A nurse is assessing a client with a suspected diagnosis of pulmonary emphysema. The nurse assesses the client for which sign that distinguishes emphysema from chronic bronchitis?
Rationale:
Marked dyspnea is the sign that distinguishes emphysema from chronic bronchitis. In emphysema, patients typically experience significant shortness of breath due to the destruction of alveoli and impaired gas exchange, whereas chronic bronchitis presents with a productive cough and less pronounced dyspnea.
A: Copious sputum production. This sign is characteristic of chronic bronchitis, where mucus overproduction leads to frequent coughing and sputum, unlike the minimal sputum seen in emphysema.
C: Minimal weight loss. Weight loss is not a distinguishing feature of emphysema; patients can maintain weight despite respiratory difficulties, which is more associated with chronic bronchitis and its effects on appetite.
D: Cough that began before the onset of dyspnea. In emphysema, the cough often develops later in the disease progression, contrasting with chronic bronchitis, where the cough is typically present early on.
A nurse is caring for a patient with a history of diabetes. The patient is complaining of blurry vision. What is the priority action?
Rationale:
Administer insulin.
In a patient with diabetes experiencing blurry vision, administering insulin addresses potential hyperglycemia, which can lead to vision changes. Quick intervention stabilizes blood glucose levels, mitigating the risk of further complications related to diabetes.
A: Monitor blood glucose levels. Monitoring is important, but immediate insulin administration is critical for correcting any elevated glucose that could be causing the visual impairment.
B: Administer a nebulizer. A nebulizer is used for respiratory issues, not for addressing complications related to diabetes or blurry vision, making it an irrelevant choice.
D: Monitor vital signs. While monitoring vital signs is essential for overall patient assessment, it does not specifically target the immediate concern of blurry vision associated with diabetes.
A patient with pneumonia has coarse crackles and thick sputum. Which action should the nurse plan to promote airway clearance?
Rationale:
C: Assist the patient to splint the chest when coughing. This action provides support to the thoracic area, which can alleviate pain and enable more effective coughing, promoting better airway clearance of thick sputum.
A: Restrict oral fluids during the day. Limiting fluid intake could lead to thicker secretions, making it more difficult for the patient to clear mucus from their airways.
B: Teach pursed-lip breathing technique. While this technique aids in prolonging exhalation, it does not directly address the need for effective clearance of thick sputum in pneumonia patients.
D: Encourage the patient to wear the nasal O2 cannula. Although oxygen delivery is essential, it does not facilitate the removal of secretions or improve airway clearance for a patient with pneumonia.
Which patient statement indicates the need for further teaching about pursed-lip breathing?
Rationale:
D: I will puff my cheeks while exhaling through pursed lips. This statement indicates the need for further teaching as pursed-lip breathing requires controlled exhalation, not puffing cheeks, which can disrupt airflow.
A: I will inhale through my nose and exhale through my mouth. This reflects a correct understanding of the technique, emphasizing proper inhalation and exhalation methods for effective breathing.
B: I should exhale for twice as long as I inhale. This demonstrates knowledge of the technique's rhythm, promoting longer exhalation to enhance oxygen exchange and reduce breathlessness.
C: I can practice pursed-lip breathing during activities. This indicates a proper understanding of applying the technique in various situations, supporting better respiratory management during physical exertion.
When caring for a patient prescribed oxygen per nasal cannula, which of the following actions is best directed toward maintaining appropriate oxygen delivery?
Rationale:
Monitoring for proper placement of the cannula tips within the patient's nares ensures that oxygen is delivered effectively and minimizes the risk of discomfort or reduced oxygen flow due to misalignment.
A: Assessing the patient frequently for reports of dyspnea focuses on patient symptoms rather than directly ensuring effective oxygen delivery, which is prioritized by verifying cannula placement.
B: Allowing enough slack on the oxygen tube to prevent kinking addresses tubing flexibility but does not guarantee that the cannula tips are correctly positioned for optimal oxygen administration.
C: Securing the oxygen tubing to the patient's clothing to prevent tugging may help in preventing dislodgement, yet does not ensure that the cannula is correctly placed for effective oxygen delivery.
A nurse is choosing a catheter to use to suction a patient's endotracheal tube via an open system. On which variable would the nurse base the size of the chosen catheter?
Rationale:
The size of the endotracheal tube. The diameter of the catheter must be compatible with the size of the endotracheal tube to ensure effective suctioning while preventing damage to the airway or tube.
A: The age of the patient. Although age may influence general care, it does not directly determine the appropriate catheter size needed for suctioning procedures.
C: The type of secretions to be suctioned. While the nature of secretions might affect suction technique, it does not dictate the catheter size selection for an endotracheal tube.
D: The height and weight of the patient. These factors may relate to overall health but do not specifically guide the determination of catheter size for suctioning an endotracheal tube.
The nurse is providing care to a client with ARDS who has a tracheostomy. The nurse will monitor the client for complications related to the loss of which protective mechanism?
Rationale:
The ability to cough. A tracheostomy bypasses the upper airway, diminishing the cough reflex, which is essential for clearing secretions and preventing aspiration, both critical in managing ARDS complications.
B: The ability to swallow. While swallowing can be affected in some cases, the primary concern in ARDS patients with tracheostomy is the compromised cough reflex essential for airway protection.
C: The ability to filter air. Although filtering air is important, the most immediate complication for an ARDS patient with a tracheostomy is related to the loss of effective coughing.
D: The ability to humidify air. Humidification is important for airway comfort but does not directly relate to the immediate protective mechanisms required to prevent lung complications in ARDS.
The primary cells involved in infection by respiratory syncytial virus (RSV) are the
Rationale:
C: squamous epithelial cells of the bronchioles and alveoli. Respiratory syncytial virus (RSV) primarily targets squamous epithelial cells lining the bronchioles and alveoli, facilitating viral entry and replication within the respiratory tract.
A: smooth muscle cells in the bronchi and bronchioles. Smooth muscle cells do not directly participate in RSV infection, as they primarily function in regulating airway constriction rather than viral interactions.
B: granular pneumonocytes in the alveoli. Granular pneumonocytes, or type II alveolar cells, play roles in surfactant production and gas exchange, not as primary targets for RSV infection.
D: macrophages and monocytes of the bronchioles and alveoli. While macrophages and monocytes are essential for immune responses, they are not the primary cells infected by RSV.
A patient with chronic bronchitis is prescribed a combination inhaler containing a corticosteroid and a long-acting beta-agonist. Which instruction should the nurse emphasize?
Rationale:
B: Rinse your mouth after using this inhaler. This instruction is vital as corticosteroids can lead to oral thrush and other infections. Rinsing minimizes this risk and promotes oral health while ensuring effective treatment for chronic bronchitis.
A: Use this inhaler during acute asthma attacks. This medication is not intended for immediate relief of acute symptoms, as it is designed for regular management of chronic conditions.
C: Take this medication only when symptoms occur. This combination inhaler serves to maintain control over chronic bronchitis symptoms and is not intended for on-demand use, which can lead to inadequate management.
D: Shake the inhaler before use. While shaking may be necessary for some inhalers, this specific combination inhaler does not require shaking, rendering this instruction irrelevant to its proper administration.
The nurse is collecting a health history for a 12-month-old child. The child lives in a home where both parents smoke, and the child has had respiratory syncytial virus twice since birth. The child's older sister was recently diagnosed with asthma. The nurse understands that this child's risk of developing asthma later in life is
Rationale:
The child's risk of developing asthma later in life is above average. Exposure to parental smoking and previous respiratory syncytial virus infections significantly increases the likelihood of asthma development, especially in children with a family history of respiratory conditions like their sister's asthma diagnosis. These factors cumulatively heighten the child's vulnerability to respiratory illnesses.
B: average. This option fails to account for the higher risks associated with both parental smoking and the child's health history, which indicate increased susceptibility to asthma.
C: below average. This choice overlooks the significant environmental and genetic risk factors that elevate the child's chances of developing asthma, contrary to the evidence presented in their health history.
D: well below average. This option misrepresents the child's situation, as it disregards the clear connections between exposure to tobacco smoke, previous illnesses, and familial asthma history that elevate risk levels.
The airway of an unconscious patient with a suspected cervical spine injury can be safely managed by which of the following:
Rationale:
Jaw thrust effectively opens the airway of an unconscious patient while minimizing movement of the cervical spine, making it a safe choice in the context of suspected spine injuries.
A: Chin lift involves tilting the head back, which could exacerbate a cervical spine injury, potentially causing further harm to the patient.
C: Cricoid pressure may help with airway management but does not ensure an open airway and can complicate intubation in an unconscious patient.
D: All of the above suggests equal efficacy, yet chin lift and cricoid pressure pose risks, making them unsuitable for managing airway in suspected cervical spine injuries.
Which nursing action is most appropriate when caring for a patient with a suspected pulmonary embolism?
Rationale:
Initiate oxygen therapy. This action is critical as it helps to alleviate hypoxemia caused by the pulmonary embolism, improving oxygenation and enhancing tissue perfusion, which are vital for patient stability.
A: Position the patient flat in bed. Keeping the patient flat could exacerbate respiratory distress and hinder optimal lung expansion, which is counterproductive in managing a pulmonary embolism.
C: Perform chest physiotherapy. While beneficial for other respiratory conditions, chest physiotherapy may not effectively address the immediate needs of a patient experiencing a pulmonary embolism's acute complications.
D: Encourage ambulation to promote circulation. Ambulation may increase the risk of dislodging the clot or worsening the patient's condition, making it an unsuitable action in the context of suspected pulmonary embolism.
A nurse is preparing a client for a bronchoscopy scheduled in an hour. What action by the nurse takes priority?
Rationale:
Ensure that informed consent is on the chart.
Validating informed consent is paramount before a bronchoscopy, as it confirms the client’s understanding and agreement to the procedure. This action safeguards the client’s rights and ensures legal compliance, making it the nurse's top priority to address before any other preparations can proceed.
B: Administer preoperative anxiolytic medication. While reducing anxiety is beneficial, it cannot occur until consent is confirmed. Rushing this step could jeopardize the client’s understanding of the procedure.
C: Reinforce any teaching done previously. Although reinforcing teaching is important, it assumes prior knowledge. Ensuring informed consent must take precedence to validate the client’s readiness for the procedure.
D: Start the preoperative antibiotic infusion. Administering antibiotics is critical but secondary to obtaining informed consent. Without consent, proceeding with medical interventions would be inappropriate and legally questionable.
A nurse is assisting a patient with ambulation. The patient becomes short of breath and begins to complain of sharp chest pain. Which action by the nurse is the first priority?
Rationale:
A: Call for the emergency response team to bring the defibrillator.
Prompt intervention is vital when a patient exhibits signs of severe distress, such as shortness of breath and chest pain. Calling for the emergency response team ensures immediate access to critical life-saving equipment and advanced medical assistance, which can be crucial in a potentially life-threatening situation.
B: Have the patient sit down in the nearest chair.
While seating the patient may provide temporary relief, it does not address the underlying emergency. Immediate medical intervention is essential for managing possible cardiac issues indicated by the symptoms.
C: Return the patient to the room and apply 100% oxygen.
Although administering oxygen can be beneficial, it does not replace the need for urgent medical evaluation. The patient's symptoms suggest a serious condition requiring prompt emergency response rather than delayed treatment.
D: Ask a coworker to get the ECG machine STAT.
Requesting an ECG machine is a valuable step, but it lacks the immediacy needed for a patient presenting with acute symptoms. Prioritizing emergency response is critical in this scenario.
What should the nurse do first if a tracheostomy tube is dislodged?
Rationale:
Attempt to reinsert the tube. In the event of a dislodged tracheostomy tube, the priority is to secure the airway by reintroducing the tube to prevent hypoxia and facilitate ventilation, which is essential for patient survival.
B: Cover the stoma with a dressing. While protecting the stoma is important, it does not address the immediate need to secure the airway for effective breathing.
C: Manually ventilate the patient. This action is necessary if the airway cannot be secured, but the first step is to attempt reinsertion of the tube to restore proper airflow.
D: Assess oxygenation. Evaluating oxygenation is essential but should follow the immediate action of attempting to reinsert the tube to ensure the airway is open for ventilation.
The nurse is planning care for a client diagnosed with chronic obstructive pulmonary disease (COPD). Which interventions should the nurse select to meet nutritional needs?
Rationale:
Provide small, frequent meals. This approach helps manage energy levels and reduces the work of breathing, which is crucial for clients with COPD. Smaller portions are easier to consume and digest, ensuring adequate nutrient intake without overwhelming the respiratory system.
B: Restrict protein intake. Protein is essential for maintaining muscle mass and supporting overall health, particularly important for individuals with COPD who may experience muscle wasting.
C: Encourage fasting. Fasting could lead to inadequate nutrient intake and energy depletion, exacerbating symptoms of COPD and negatively impacting overall health and recovery.
D: Limit fluid intake. Adequate hydration is vital for maintaining mucus viscosity and promoting effective airway clearance, which is critical for individuals managing COPD symptoms.
What category of medications may be administered by nebulizer or metered-dose inhaler to open narrowed airways?
Rationale:
Bronchodilators are the category of medications that may be administered by nebulizer or metered-dose inhaler to open narrowed airways. These medications work by relaxing the muscles around the airways, facilitating easier airflow and improving breathing efficiency. They are crucial in managing conditions such as asthma and chronic obstructive pulmonary disease (COPD).
A: bronchoconstrictors These medications would exacerbate airway narrowing rather than alleviate it, contradicting the objective of improving airflow. They are not used to treat respiratory conditions effectively.
B: antihistamines Primarily designed to combat allergic reactions, antihistamines do not target airway constriction. They lack the mechanism needed for immediate airway dilation, making them unsuitable for this purpose.
C: narcotics These substances are primarily pain relievers and have no relevance in treating airway constriction. Their effects do not address the respiratory issues associated with narrowed airways.
The nurse assesses the chest of a patient with pneumococcal pneumonia. Which finding would the nurse expect?
Rationale:
Increased tactile fremitus. This finding occurs in pneumococcal pneumonia due to lung consolidation, where denser lung tissue transmits vibrations more effectively, thereby enhancing the tactile sensation during assessment.
B: Dry, nonproductive cough. Pneumococcal pneumonia typically presents with a productive cough, not a dry one, indicating that mucus is present in the airways and lungs.
C: Hyperresonance to percussion. This sound suggests air trapping or pneumothorax, which is not characteristic of pneumonia; instead, pneumonia usually produces dullness due to fluid or consolidation.
D: A grating sound on auscultation. A grating sound, or pleural friction rub, indicates pleuritis rather than pneumonia, which primarily manifests with abnormal breath sounds, such as crackles or bronchial breath sounds.
A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with increased dyspnea. Which laboratory test result requires immediate intervention?
Rationale:
A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with increased dyspnea. A PaO2 of 55 mmHg requires immediate intervention.
A PaO2 of 55 mmHg indicates severe hypoxemia, which can lead to respiratory failure in patients with COPD. This critical level necessitates prompt oxygen therapy or other interventions to stabilize the patient and improve oxygenation.
A: Hemoglobin of 15 g/dL. This level is within the normal range, suggesting adequate oxygen-carrying capacity and does not require urgent intervention in this context.
C: pH of 7.35. While this indicates acidosis, it is not as immediately life-threatening as the severely low PaO2 level that signifies acute respiratory distress.
D: HCO3 of 24 mEq/L. This bicarbonate level falls within the normal range and does not signify any immediate metabolic disturbance that would warrant urgent medical action.
Which patient requires rapid assessment due to a muffled voice?
Rationale:
A: A patient with a muffled voice requires rapid assessment. This symptom can indicate serious conditions such as airway obstruction or trauma, necessitating immediate evaluation to prevent complications and ensure timely intervention.
B: A patient with a nasal fracture may experience pain and swelling, but a muffled voice specifically signals potential airway issues, which demands more urgent attention than a fracture alone.
C: A patient with epistaxis primarily presents with bleeding from the nose. While it can lead to airway concerns, the immediate indicator here is the muffled voice, not just bleeding.
D: A patient with allergic rhinitis typically presents with congestion and sneezing. Although it may cause voice changes, it is less urgent than the potential airway compromise indicated by a muffled voice.
The emergency department nurse is evaluating the effectiveness of therapy for a patient who has received treatment during an asthma attack. Which assessment finding is the best indicator that the therapy has been effective?
Rationale:
O₂ saturation is >90%.
A saturation level above 90% signifies adequate oxygenation and effective bronchodilation, indicating that the therapy during the asthma attack has successfully improved the patient's respiratory function and overall gas exchange.
A: No wheezes are audible. Absence of wheezes suggests improvement, yet it doesn't guarantee sufficient oxygenation or effective therapy, as wheezing can sometimes persist despite adequate treatment.
C: Accessory muscle use has decreased. While reduced accessory muscle use indicates less respiratory distress, it does not directly measure oxygenation levels, which are crucial for evaluating therapy effectiveness.
D: Respiratory rate is 16 breaths/minute. A respiratory rate within normal limits may indicate stability, but it does not provide specific information about oxygenation or the success of the treatment given.
A client with asthma is prescribed a corticosteroid inhaler. What should the nurse emphasize in client teaching?
Rationale:
Rinse your mouth after each use to prevent thrush. This practice is crucial as corticosteroids can lead to fungal infections in the mouth, and rinsing helps minimize this risk while promoting oral hygiene.
A: Use the inhaler only during an asthma attack. Corticosteroids are intended for regular use to control inflammation, not just during acute episodes.
C: Take the medication before using a bronchodilator. The effective sequence is to use the bronchodilator first to open airways, followed by the corticosteroid for optimal delivery.
D: Increase fluid intake after using the inhaler. While hydration is generally beneficial, it does not specifically relate to the use of a corticosteroid inhaler or its effects.
A nurse is discussing ventilation and perfusion with a newly licensed nurse. The nurse should include in the discussion that the exchange of oxygen and carbon dioxide occurs at which of the following locations?
Rationale:
B: Alveoli. The alveoli are tiny air sacs in the lungs where the critical exchange of oxygen and carbon dioxide takes place, enabling efficient gas exchange with the bloodstream.
A: Trachea. The trachea serves as a passageway for air to enter the lungs but does not facilitate the actual exchange of gases.
C: Diaphragm. The diaphragm is a muscle that aids in breathing by expanding and contracting the thoracic cavity, rather than being a site for gas exchange.
D: Bronchial tubes. Bronchial tubes direct air to the lungs but are not the locations where oxygen and carbon dioxide are exchanged, as that occurs in the alveoli.
The nurse teaches a patient about peak flow meter use. Which action by the patient indicates that teaching was successful?
Rationale:
The patient uses an albuterol (Ventolin HFA) inhaler for peak flows in the yellow zone. This indicates successful teaching, as patients should utilize inhalers when their peak flow readings are in the yellow zone, suggesting the need for additional medication to prevent worsening symptoms.
A: The patient inhales rapidly through the peak flow meter mouthpiece. Rapid inhalation does not provide an accurate reading; a slow, deep breath is required for proper use.
B: The patient takes montelukast (Singulair) for peak flows in the red zone. Montelukast is a preventive medication, not an immediate solution, and should not be used for urgent red zone readings.
C: The patient calls the health care provider when the peak flow is in the green zone. The green zone indicates stable condition, not requiring immediate consultation; this action shows misunderstanding of the peak flow zones.
A patient with tuberculosis is taking rifampin. The patient reports orange-colored urine. What should the nurse do?
Rationale:
Reassure the patient this is a normal side effect. Rifampin can cause orange-colored urine due to its metabolic byproducts, which are harmless and not indicative of any underlying health issues related to tuberculosis treatment.
B: Hold the medication and notify the provider. This action is unnecessary since orange urine is a known benign side effect of rifampin and does not signal a need to discontinue treatment.
C: Assess the patient for jaundice. The presence of orange urine does not correlate with jaundice, which is characterized by yellowing of the skin and eyes, warranting a different clinical assessment.
D: Recommend increasing fluid intake. While hydration is generally beneficial, it does not address the harmless nature of the orange urine and does not require a change in the patient’s current fluid regimen.
Which of the following is TRUE in colostomy feeding?
Rationale:
B: Pour 30 ml of water before and after feeding administration. This practice ensures that the stoma remains hydrated and helps to flush the feeding tube, preventing blockages and maintaining optimal function during colostomy feeding.
A: Hold the syringe 18 inches above the stoma and administer the feeding slowly. This height may lead to excessive pressure and discomfort, adversely affecting the feeding process.
C: Insert the ostomy feeding tube 1 inch towards the stoma. Inserting the tube too deeply can risk injury to the stoma and surrounding tissues, causing complications.
D: A Pink stoma means that circulation towards the stoma is all well. While a pink stoma typically indicates good circulation, other factors may influence stoma health and function, requiring further assessment.
Which task can be delegated to an LPN/LVN?
Rationale:
Suctioning a stable patient can be delegated to an LPN/LVN. This task involves basic nursing skills that LPNs/LVNs are trained to perform, ensuring patient safety while managing airway clearance under stable conditions.
A: Patient assessment requires comprehensive knowledge and critical thinking, typically reserved for RNs who can evaluate complex patient needs and make informed decisions based on their findings.
C: Patient teaching necessitates a deeper understanding of medical information and the ability to tailor education to individual patient needs, which is primarily within the scope of registered nurses.
D: Adjusting oxygen settings involves critical decision-making and clinical judgment to ensure patient safety, tasks that are generally performed by registered nurses rather than LPNs/LVNs.
Transmission of mycobacterium tuberculosis is through:
Rationale:
Transmission of mycobacterium tuberculosis is through airborne transmission. Airborne transmission involves the inhalation of aerosolized particles containing the bacteria, allowing them to reach the lungs of a susceptible person, facilitating infection.
A: Droplet transmission. This mode involves larger respiratory droplets that do not remain suspended in the air, thus limiting the distance they can travel compared to airborne particles.
B: Direct contact transmission. This method requires physical interaction with an infected individual or contaminated surfaces, which is not how tuberculosis spreads in the majority of cases.
C: Vector transmission. This type of transmission relies on an intermediary organism, like insects, which is not applicable for tuberculosis, as it spreads directly through the air.
A client with pulmonary fibrosis is receiving supplemental oxygen. What is the primary goal of oxygen therapy in this condition?
Rationale:
To maintain tissue oxygenation. In pulmonary fibrosis, lung function is compromised, leading to inadequate oxygen delivery to tissues. Supplemental oxygen therapy aims to enhance oxygen levels in the bloodstream, thereby ensuring that vital organs and tissues receive sufficient oxygen for optimal functioning.
A: To cure the underlying disease. Oxygen therapy does not address the fibrotic changes in lung tissue, which remain irreversible and require different therapeutic approaches for management.
C: To prevent the need for mechanical ventilation. While oxygen therapy can support breathing, it does not guarantee the avoidance of mechanical ventilation, especially in advanced stages of pulmonary fibrosis.
D: To improve exercise tolerance permanently. Oxygen therapy may enhance exercise capacity temporarily, but it does not fundamentally alter the disease's progression or lead to lasting improvements in exercise tolerance.
The clinic nurse is teaching a patient with acute sinusitis. Which interventions should the nurse plan to include in the teaching session (select one that doesn't apply)?
Rationale:
Blowing the nose should be avoided to decrease the nosebleed risk. This intervention is not applicable because blowing the nose can actually help clear mucus and relieve sinus pressure, rather than causing harm.
A: Decongestants can be used to relieve swelling. This option correctly highlights that decongestants effectively reduce nasal swelling, promoting better airflow and comfort in patients with sinusitis.
C: Taking a hot shower will increase sinus drainage and decrease pain. This option correctly suggests that steam from a hot shower can facilitate sinus drainage and provide symptomatic relief for sinusitis.
D: Saline nasal spray can be made at home and used to wash out secretions. This option correctly indicates that homemade saline sprays are effective for cleansing nasal passages and clearing secretions in sinusitis patients.
A nurse is assessing a client with a suspected diagnosis of pulmonary emphysema. The nurse assesses the client for which sign that distinguishes emphysema from chronic bronchitis?
Rationale:
Marked dyspnea is a key sign that distinguishes emphysema from chronic bronchitis, as patients with emphysema often experience significant difficulty in breathing, particularly during physical exertion, reflecting the disease's impact on lung function.
A: Copious sputum production typically characterizes chronic bronchitis rather than emphysema, where sputum is often minimal, highlighting a fundamental difference in the pathological features of each condition.
C: Minimal weight loss is not a definitive sign of emphysema; patients may experience weight loss, but it is not a distinguishing factor when comparing it to chronic bronchitis.
D: Cough that began before the onset of dyspnea generally indicates chronic bronchitis, as emphysema usually features a later onset of cough in conjunction with pronounced breathing difficulties.
A nurse is caring for a patient with a history of diabetes. The patient is complaining of blurry vision. What is the priority action?
Rationale:
Administer insulin.
Insulin is crucial for managing blood glucose levels in diabetic patients, particularly when symptoms like blurry vision arise, indicating possible hyperglycemia. Timely administration can prevent further complications and stabilize the patient's condition.
A: Monitor blood glucose levels. While monitoring is important, immediate insulin administration takes precedence to address the symptomatic issue and prevent progression of hyperglycemia.
B: Administer a nebulizer. A nebulizer is irrelevant in this scenario, as the patient's complaint of blurry vision relates to diabetes management rather than respiratory concerns.
D: Monitor vital signs. Although vital signs are essential for overall assessment, they do not directly address the urgent need for insulin in a patient experiencing blurry vision related to diabetes.
A patient with pneumonia has coarse crackles and thick sputum. Which action should the nurse plan to promote airway clearance?
Rationale:
Assist the patient to splint the chest when coughing.
This action supports the chest wall during coughing, reducing pain and improving the effectiveness of cough efforts, which is crucial for clearing thick sputum in pneumonia patients.
A: Restrict oral fluids during the day. Reducing fluid intake can lead to thicker secretions, making airway clearance more difficult and exacerbating the patient's respiratory condition.
B: Teach pursed-lip breathing technique. While beneficial for improving breathing patterns, this technique does not directly assist in clearing thick sputum from the airways.
D: Encourage the patient to wear the nasal O2 cannula. Providing oxygen support is important but does not address the need for effective airway clearance in the presence of thick sputum.
Which patient statement indicates the need for further teaching about pursed-lip breathing?
Rationale:
I will puff my cheeks while exhaling through pursed lips. Pursed-lip breathing involves exhaling gently and slowly through pursed lips, helping to control breathing. Puffing the cheeks suggests improper technique that may hinder the effectiveness of this method.
A: I will inhale through my nose and exhale through my mouth. This statement aligns with pursed-lip breathing, emphasizing proper inhalation and controlled exhalation for optimal respiratory benefits.
B: I should exhale for twice as long as I inhale. This guideline is accurate, as extending the exhalation duration aids in reducing breathlessness and enhancing lung function during pursed-lip breathing.
C: I can practice pursed-lip breathing during activities. This reflects a correct understanding, as pursed-lip breathing can be effectively utilized during various physical activities to improve oxygenation and overall respiratory efficiency.
When caring for a patient prescribed oxygen per nasal cannula, which of the following actions is best directed toward maintaining appropriate oxygen delivery?
Rationale:
Monitoring for proper placement of the cannula tips within the patient's nares ensures optimal oxygen delivery, as misalignment can significantly reduce the effectiveness of oxygen therapy and compromise patient safety.
A: Assessing the patient frequently for reports of dyspnea does not directly influence the oxygen delivery itself, although it is important for overall patient monitoring and response evaluation.
B: Allowing enough slack on the oxygen tube to prevent kinking addresses potential mechanical issues but does not ensure that the cannula is correctly positioned for effective oxygen delivery.
C: Securing the oxygen tubing to the patient's clothing to prevent tugging helps maintain stability but does not guarantee the correct placement of the cannula for optimal oxygen flow.
A nurse is choosing a catheter to use to suction a patient's endotracheal tube via an open system. On which variable would the nurse base the size of the chosen catheter?
Rationale:
The size of the endotracheal tube. The catheter's size must correlate with the endotracheal tube's diameter to ensure effective suctioning while minimizing trauma to the airway and preventing complications during the procedure.
A: The age of the patient. While age can influence airway size, it does not provide a definitive measurement for catheter selection in relation to endotracheal tube size.
C: The type of secretions to be suctioned. The consistency of secretions may affect suction techniques but does not dictate the catheter diameter needed for effective suctioning through the endotracheal tube.
D: The height and weight of the patient. Physical dimensions might suggest airway size, yet they do not directly determine the appropriate catheter size for suctioning a specific endotracheal tube.
The nurse is providing care to a client with ARDS who has a tracheostomy. The nurse will monitor the client for complications related to the loss of which protective mechanism?
Rationale:
The ability to cough. The cough reflex is crucial for clearing secretions and preventing aspiration in clients with tracheostomies, especially those with ARDS, as they are at high risk for complications.
B: The ability to swallow. While swallowing is essential for nutrition, it does not directly relate to airway protection or the management of respiratory complications in this context.
C: The ability to filter air. Although filtering air is vital, a tracheostomy primarily bypasses the upper airway, so this mechanism's loss is less critical than the cough reflex in this situation.
D: The ability to humidify air. Humidification is important for airway health, but loss of this function does not pose as immediate a risk to airway protection as the inability to cough.
The primary cells involved in infection by respiratory syncytial virus (RSV) are the
Rationale:
The primary cells involved in infection by respiratory syncytial virus (RSV) are the squamous epithelial cells of the bronchioles and alveoli.
Squamous epithelial cells line the respiratory tract and serve as the primary entry point for RSV, facilitating the virus's attachment and subsequent infection. Their location in the bronchioles and alveoli positions them as critical targets for the virus, leading to respiratory illnesses.
A: smooth muscle cells in the bronchi and bronchioles. These cells play a role in regulating airway constriction but do not directly participate in RSV infection or replication processes.
B: granular pneumonocytes in the alveoli. While these cells are involved in surfactant production, they are not the primary targets for RSV infection, which prefers epithelial cells.
D: macrophages and monocytes of the bronchioles and alveoli. These immune cells respond to infections but are not the primary cells infected by RSV, which primarily targets epithelial cells.
A patient with chronic bronchitis is prescribed a combination inhaler containing a corticosteroid and a long-acting beta-agonist. Which instruction should the nurse emphasize?
Rationale:
Rinse your mouth after using this inhaler. This instruction is crucial as it helps prevent oral thrush and other side effects associated with corticosteroid use, ensuring the medication is used safely and effectively.
A: Use this inhaler during acute asthma attacks. This inhaler is designed for maintenance therapy, not immediate relief during exacerbations, which requires a rescue inhaler instead.
C: Take this medication only when symptoms occur. Chronic bronchitis requires consistent medication use for optimal control, not just when symptoms are present, to manage inflammation and prevent exacerbations.
D: Shake the inhaler before use. While shaking may benefit some inhalers, this specific combination inhaler does not require shaking, making this instruction unnecessary and potentially misleading for proper usage.
The nurse is collecting a health history for a 12-month-old child. The child lives in a home where both parents smoke, and the child has had respiratory syncytial virus twice since birth. The child's older sister was recently diagnosed with asthma. The nurse understands that this child's risk of developing asthma later in life is
Rationale:
The child's risk of developing asthma later in life is above average. Given the child's frequent respiratory infections, exposure to parental smoking, and a family history of asthma, these factors significantly elevate the likelihood of future respiratory issues, including asthma.
B: average Exposure to smoking and recurrent respiratory infections typically leads to a higher risk, making this assessment insufficiently cautious regarding the child's health status.
C: below average Not considering the significant environmental and genetic factors at play, such as parental smoking habits and a sibling with asthma, leads to an underestimation of risk.
D: well below average This option fails to recognize the interplay of environmental influences, recurrent illness, and family history that collectively increase the child's risk profile for asthma considerably.
The airway of an unconscious patient with a suspected cervical spine injury can be safely managed by which of the following:
Rationale:
Jaw thrust is the safest method for managing the airway of an unconscious patient with a suspected cervical spine injury. This technique minimizes neck movement, thereby reducing the risk of exacerbating potential spinal injuries while effectively opening the airway.
A: Chin lift This method involves tilting the head back, which can compromise spinal stability and potentially worsen a cervical spine injury.
C: Cricoid pressure This technique can obstruct the airway and is not suitable for patients with suspected cervical spine injuries due to the risk of further trauma.
D: All of the above Combining these methods would increase the chances of causing harm to the cervical spine, making it unsuitable for patients with suspected injuries.
Which nursing action is most appropriate when caring for a patient with a suspected pulmonary embolism?
Rationale:
Initiate oxygen therapy. Oxygen therapy is crucial for a patient with a suspected pulmonary embolism as it helps alleviate hypoxemia, ensuring adequate oxygenation to vital organs and supporting respiratory function during this critical condition.
A: Position the patient flat in bed. Keeping the patient flat can exacerbate respiratory distress and is not conducive to optimal lung expansion or oxygenation.
C: Perform chest physiotherapy. Chest physiotherapy may not be suitable as it could dislodge a clot or worsen the patient’s condition, failing to address the immediate need for oxygenation.
D: Encourage ambulation to promote circulation. Encouraging ambulation poses a risk of increasing the workload on the heart and may lead to further complications, as the patient requires stabilization first.
A nurse is preparing a client for a bronchoscopy scheduled in an hour. What action by the nurse takes priority?
Rationale:
Ensure that informed consent is on the chart.
Obtaining informed consent is critical prior to any medical procedure, including bronchoscopy. It ensures that the client understands the procedure, its risks and benefits, and confirms their agreement. This step is essential for legal and ethical compliance, making it the nurse’s top priority when preparing for the procedure.
B: Administer preoperative anxiolytic medication. While reducing anxiety is important, it cannot take precedence over ensuring the client has provided informed consent for the procedure.
C: Reinforce any teaching done previously. Although reviewing information is beneficial, it should follow the acquisition of informed consent to ensure the client is adequately prepared for the procedure.
D: Start the preoperative antibiotic infusion. Administering antibiotics may be necessary but must occur after confirming that the client has given informed consent, which is fundamental for legal and ethical reasons.
A nurse is assisting a patient with ambulation. The patient becomes short of breath and begins to complain of sharp chest pain. Which action by the nurse is the first priority?
Rationale:
A: Call for the emergency response team to bring the defibrillator.
Immediate action is crucial when a patient exhibits shortness of breath and sharp chest pain, as these symptoms may indicate a cardiac event. Activating emergency assistance ensures timely intervention, potentially saving the patient’s life.
B: Have the patient sit down in the nearest chair.
While providing support is vital, simply having the patient sit does not address potential life-threatening issues and delays necessary emergency interventions that may be required.
C: Return the patient to the room and apply 100% oxygen.
Though applying oxygen could be beneficial, returning to the room may waste valuable time. Rapid response is essential given the severity of the patient’s symptoms.
D: Ask a coworker to get the ECG machine STAT.
Requesting an ECG is important, yet prioritizing immediate emergency response takes precedence. The patient's life may be in jeopardy, necessitating swift action beyond diagnostic measures.
What should the nurse do first if a tracheostomy tube is dislodged?
Rationale:
Attempt to reinsert the tube. Immediate reinsertion of the tracheostomy tube is crucial to maintain the airway and prevent hypoxia. This action allows for continued ventilation and oxygenation, minimizing the risk of respiratory distress.
B: Cover the stoma with a dressing. While covering the stoma can help, it does not address the critical need for airway patency and could lead to suffocation.
C: Manually ventilate the patient. Manual ventilation may be necessary but cannot be effectively performed without ensuring the airway is clear and the tube is in place first.
D: Assess oxygenation. Although assessing oxygenation is important, prioritizing airway reestablishment is essential to prevent immediate respiratory failure before any assessment can be accurately made.
The nurse is planning care for a client diagnosed with chronic obstructive pulmonary disease (COPD). Which interventions should the nurse select to meet nutritional needs?
Rationale:
Provide small, frequent meals. This approach aids in managing COPD by preventing excessive fatigue during meals, ensuring better nutrient intake, enhancing overall calorie consumption, and improving the client’s energy levels for daily activities.
B: Restrict protein intake. Adequate protein is essential for maintaining muscle mass and supporting overall health in COPD patients, making this option detrimental to their nutritional needs.
C: Encourage fasting. Fasting deprives the body of essential nutrients, which is counterproductive for individuals with COPD who require a consistent intake of energy and nutrients to maintain their health.
D: Limit fluid intake. Hydration is crucial for COPD patients to help thin mucus; limiting fluids can lead to increased thickening of secretions, exacerbating breathing difficulties and overall health issues.
What category of medications may be administered by nebulizer or metered-dose inhaler to open narrowed airways?
Rationale:
Bronchodilators are medications that may be administered by nebulizer or metered-dose inhaler to open narrowed airways. These drugs specifically relax the muscles around the airways, improving airflow and alleviating breathing difficulties often associated with asthma or COPD.
A: bronchoconstrictors These substances cause narrowing of the airways, leading to increased difficulty in breathing, which contradicts the desired effect of opening the airways.
B: antihistamines Primarily used to alleviate allergy symptoms, antihistamines do not have a direct role in relaxing airway muscles or treating conditions related to narrowed airways.
C: narcotics While they may relieve pain and induce sedation, narcotics do not possess properties to expand or open airways, making them unsuitable for respiratory treatments.
The nurse assesses the chest of a patient with pneumococcal pneumonia. Which finding would the nurse expect?
Rationale:
Increased tactile fremitus. This finding occurs due to the presence of fluid or consolidated lung tissue associated with pneumococcal pneumonia, leading to enhanced vibrations when the patient speaks.
B: Dry, nonproductive cough. Pneumococcal pneumonia typically presents with a productive cough, as the infection usually causes mucus production, contrary to the characteristics of a dry cough.
C: Hyperresonance to percussion. Hyperresonance suggests air-filled spaces, often indicating conditions like pneumothorax or emphysema, which do not align with the solidified lung tissue seen in pneumonia.
D: A grating sound on auscultation. A grating sound, or pleural friction rub, typically indicates pleurisy rather than pneumonia, where breath sounds and crackles are more commonly associated with fluid or consolidation.
A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with increased dyspnea. Which laboratory test result requires immediate intervention?
Rationale:
A PaO2 of 55 mmHg requires immediate intervention. This level indicates severe hypoxemia, which poses critical risks for a patient with COPD, necessitating urgent treatment to restore adequate oxygenation.
A: Hemoglobin of 15 g/dL. This value reflects a normal range, indicating no immediate concern related to oxygen-carrying capacity in the context of respiratory distress.
C: pH of 7.35. Although this indicates acidosis, it is not as urgent as the critically low PaO2 level requiring prompt oxygenation support.
D: HCO3 of 24 mEq/L. This bicarbonate level is within the normal range, suggesting no metabolic imbalance requiring immediate correction in the context of the patient's respiratory condition.
Which patient requires rapid assessment due to a muffled voice?
Rationale:
A: A patient with a muffled voice requires rapid assessment as this symptom can indicate serious conditions such as airway obstruction or trauma. Prompt evaluation is crucial to prevent potential respiratory distress or complications.
B: Patient with nasal fracture typically presents with facial deformity and nasal obstruction, but a muffled voice is not a primary concern indicating immediate evaluation.
C: Patient with epistaxis may experience bleeding from the nose, yet this condition does not inherently cause a muffled voice, which suggests more urgent airway issues.
D: Patient with allergic rhinitis usually exhibits nasal congestion and sneezing; however, this condition does not typically result in a muffled voice that necessitates rapid assessment.
The emergency department nurse is evaluating the effectiveness of therapy for a patient who has received treatment during an asthma attack. Which assessment finding is the best indicator that the therapy has been effective?
Rationale:
O₂ saturation is >90%. This measurement signifies that the patient’s lungs are effectively exchanging gases, indicating improved oxygenation and successful management of the asthma attack, validating the therapy’s effectiveness.
A: No wheezes are audible. While the absence of wheezes suggests some improvement, it does not provide a comprehensive picture of the patient’s overall respiratory function and oxygenation status.
C: Accessory muscle use has decreased. Although a reduction in accessory muscle usage implies relief from respiratory distress, it does not directly measure oxygenation, which is critical in assessing therapy effectiveness.
D: Respiratory rate is 16 breaths/minute. A normal respiratory rate does not guarantee effective therapy, as it overlooks critical factors like oxygen saturation and overall respiratory function during and after an asthma attack.
A client with asthma is prescribed a corticosteroid inhaler. What should the nurse emphasize in client teaching?
Rationale:
Rinse your mouth after each use to prevent thrush. This practice is crucial as corticosteroids can cause oral thrush, a fungal infection; rinsing helps minimize this risk and promotes oral hygiene.
A: Use the inhaler only during an asthma attack. Corticosteroids are designed for regular use to control inflammation, not just for immediate relief during an attack.
C: Take the medication before using a bronchodilator. The typical recommendation is to use the bronchodilator first to open airways, followed by the corticosteroid for optimal effect.
D: Increase fluid intake after using the inhaler. While hydration is important, it does not directly relate to the use of corticosteroid inhalers or their side effects.
A nurse is discussing ventilation and perfusion with a newly licensed nurse. The nurse should include in the discussion that the exchange of oxygen and carbon dioxide occurs at which of the following locations?
Rationale:
Oxygen and carbon dioxide exchange occurs at the alveoli.
Alveoli are tiny air sacs in the lungs where gas exchange takes place. Their thin walls facilitate the transfer of oxygen into the bloodstream and carbon dioxide out, making them essential for effective respiration and overall respiratory function.
A: Trachea The trachea serves as a passage for air but does not facilitate gas exchange.
C: Diaphragm The diaphragm is a muscle that aids in breathing but does not directly participate in gas exchange.
D: Bronchial tubes The bronchial tubes transport air to the lungs but do not engage in the exchange of gases.
The nurse teaches a patient about peak flow meter use. Which action by the patient indicates that teaching was successful?
Rationale:
D: The patient uses an albuterol (Ventolin HFA) inhaler for peak flows in the yellow zone. This indicates successful teaching, as patients are instructed to use their rescue inhaler when peak flow readings fall within this range, signaling potential respiratory distress that requires intervention.
A: The patient inhales rapidly through the peak flow meter mouthpiece. Proper technique involves a strong, swift blast of air, not rapid inhalation, which could lead to inaccurate readings.
B: The patient takes montelukast (Singulair) for peak flows in the red zone. Montelukast is a maintenance medication and should not be used as an immediate response in emergency situations indicated by the red zone.
C: The patient calls the health care provider when the peak flow is in the green zone. Green zone readings indicate stable condition and self-management, negating the necessity for contacting a provider at that moment.
A patient with tuberculosis is taking rifampin. The patient reports orange-colored urine. What should the nurse do?
Rationale:
Reassure the patient this is a normal side effect. Rifampin is known to cause a harmless discoloration of body fluids, including urine, which is a common and expected reaction to the medication.
B: Hold the medication and notify the provider. There is no indication that the orange urine signifies a serious or harmful condition, so immediate action is unnecessary.
C: Assess the patient for jaundice. Orange urine does not indicate jaundice; instead, it is a benign effect of rifampin and not related to liver dysfunction.
D: Recommend increasing fluid intake. Increased fluid intake does not address the harmless side effect of rifampin-induced orange urine, as the color change is not a sign of dehydration.
Which of the following is TRUE in colostomy feeding?
Rationale:
B: Pour 30 ml of water before and after feeding administration. This practice is essential for maintaining hydration and ensuring the feeding process is smooth, promoting optimal nutrient absorption and preventing complications.
A: Hold the syringe 18 inches above the stoma and administer the feeding slowly. This method may cause discomfort and should follow specific height guidelines for effective feeding.
C: Insert the ostomy feeding tube 1 inch towards the stoma. This measurement is inappropriate and can lead to complications; proper insertion techniques require careful attention to distance and direction.
D: A Pink stoma means that circulation towards the stoma is all well. While a pink stoma often indicates good blood flow, various factors can affect stoma health beyond color alone.
Which task can be delegated to an LPN/LVN?
Rationale:
Suctioning a stable patient. LPNs/LVNs are trained to perform suctioning on stable patients, which involves clearing airways without requiring the extensive clinical judgment necessary for more complex assessments or interventions.
A: Patient assessment. This task involves critical thinking and complex decision-making that typically exceeds the scope of practice for LPNs/LVNs, necessitating an RN's expertise for comprehensive evaluations.
C: Patient teaching. Educating patients often demands a depth of knowledge and assessment skills that go beyond the LPN/LVN role, requiring RNs to ensure information is conveyed accurately and effectively.
D: Adjusting oxygen settings. Modifying oxygen levels requires careful assessment and clinical judgment, which are responsibilities typically reserved for RNs, ensuring patient safety and appropriate care interventions.
Transmission of mycobacterium tuberculosis is through:
Rationale:
Transmission of mycobacterium tuberculosis is through airborne transmission. This pathogen spreads when an infected person coughs or sneezes, releasing tiny droplets containing the bacteria into the air, which can be inhaled by others.
A: Droplet transmission Tiny respiratory droplets are indeed produced, but they usually contain larger particles that do not remain airborne long enough to facilitate tuberculosis transmission effectively.
B: Direct contact transmission Tuberculosis does not spread through skin-to-skin contact, as it primarily requires inhalation of aerosolized particles from an infected person's respiratory secretions.
C: Vector transmission Mycobacterium tuberculosis does not rely on vectors like insects or animals for transmission, as it is exclusively airborne and requires human interaction for spread.
A client with pulmonary fibrosis is receiving supplemental oxygen. What is the primary goal of oxygen therapy in this condition?
Rationale:
To maintain tissue oxygenation. In pulmonary fibrosis, oxygen therapy primarily aims to ensure that the body’s tissues receive adequate oxygen, alleviating symptoms and improving quality of life for the patient.
A: To cure the underlying disease. Oxygen therapy does not address the root cause of pulmonary fibrosis, which is a progressive and irreversible lung condition requiring other treatment approaches.
C: To prevent the need for mechanical ventilation. While oxygen therapy can support breathing, it doesn’t guarantee that mechanical ventilation won't be necessary as the disease progresses and respiratory failure occurs.
D: To improve exercise tolerance permanently. Oxygen therapy may enhance exercise tolerance temporarily, but it does not provide a lasting solution, as the underlying disease continues to progress.
The clinic nurse is teaching a patient with acute sinusitis. Which interventions should the nurse plan to include in the teaching session (select one that doesn't apply)?
Rationale:
Blowing the nose should be avoided to decrease the nosebleed risk. This intervention is not applicable; patients with acute sinusitis can benefit from gentle nose blowing to clear mucus and relieve pressure.
A: Decongestants can be used to relieve swelling. This option promotes symptom relief by reducing nasal congestion and facilitating easier breathing, which is essential in managing acute sinusitis.
C: Taking a hot shower will increase sinus drainage and decrease pain. The steam from a hot shower helps to open nasal passages and promote drainage, providing symptomatic relief for sinusitis sufferers.
D: Saline nasal spray can be made at home and used to wash out secretions. This method is effective for moisturizing nasal passages, helping to clear mucus and alleviate discomfort associated with sinusitis.
