You are called to assist a pregnant female in the 24th week gestation period according to her due date. The pale 26-year-old patient is found supine in bed, complaining of dizziness/weakness with extreme nausea. The patient denies vaginal bleeding, amniotic fluid leakage, or abdominal pain. There are no signs of imminent birth or active labor. She reports receiving normal prenatal care with no associated problems found during the pregnancy. Her heart rate is 126-130 beats per minute; her blood pressure is 80 mmHg systolic while her skin is cool and pale. Which of the following conditions is most likely to cause the patient's presentation?
Rationale:
Supine hypotension is the most likely cause of the patient's symptoms.
Supine hypotension occurs when the gravid uterus compresses the inferior vena cava in the supine position, reducing venous return and cardiac output, causing dizziness, weakness, pallor, tachycardia, and hypotension. The patient’s 24-week gestation, cool pale skin, and low blood pressure without bleeding or labor signs align perfectly with this diagnosis.
A: Uterine rupture would present with severe abdominal pain, bleeding, and fetal distress, which are absent here.
B: Spontaneous abortion typically involves vaginal bleeding and cramping, symptoms the patient denies.
D: Placenta previa causes painless vaginal bleeding, not hypotension or supine-position-related symptoms.
You are ordered to administer 3 mg/min of lidocaine via intravenous infusion to your cardiac patient who presents with a heart rate greater than 130 beats per minute as well as greater than 10 multifocal PVCs every minute. Therefore, you quickly but carefully mix 2 grams of the medication in 500 mL of normal saline and attach micro-drip tubing to the solution bag. Which of the following drip rates would effectively deliver the ordered dose of lidocaine?
Rationale:
Administering lidocaine at 3 mg/min requires a drip rate of 30 gtts/min.
B: This option matches the required infusion rate when calculating the dosage concentration and micro-drip factor. Using 2 grams in 500 mL, 3 mg/min corresponds precisely to 30 drops per minute with micro-drip tubing, ensuring accurate delivery of the therapeutic dose to the patient.
A: 15 gtts/min delivers only half the necessary amount, resulting in subtherapeutic dosing and inadequate treatment of high heart rate and multifocal PVCs.
C: 60 gtts/min doubles the intended infusion rate, risking lidocaine toxicity and adverse cardiac effects due to overdose.
D: 45 gtts/min exceeds the target rate by 50%, potentially causing excessive plasma levels and increasing risk of lidocaine toxicity.
The main part of a word that gives it meaning is the
Rationale:
The main part of a word that gives it meaning is the Root.
The root serves as the fundamental base of a word, carrying its primary semantic content. Prefixes and suffixes modify or add nuance, but the root provides the essential meaning. Understanding roots helps decode unfamiliar words by revealing their core concept, making root knowledge crucial for vocabulary development and comprehension in language learning.
A: Prefix adds meaning to the beginning of a word but does not carry the core meaning itself; it modifies the root’s meaning rather than providing the base.
C: Suffix attaches to the end and changes grammatical function or tense; it does not hold the primary semantic content of the word.
D: Abbreviation shortens words or phrases, representing them in a concise form, but does not relate to the fundamental meaning within word structure.
Which of the following is true of mechanical lifts?
Rationale:
Mechanical lifts help prevent injury to the body. Mechanical lifts reduce the physical strain on caregivers by supporting the weight of residents during transfers, minimizing the risk of musculoskeletal injuries. They provide safe and efficient assistance, ensuring both resident and caregiver safety. Using these devices properly promotes ergonomic handling and reduces reliance on manual lifting techniques that can cause harm.
B: It is safer for an NA to lift a resident without the help of a mechanical lift contradicts safety guidelines, as manual lifting increases the risk of injury to both the caregiver and resident due to insufficient support and strain.
C: There is only one kind of mechanical lift ignores the variety available, such as hydraulic, electric, and sling lifts, each designed for different patient needs and environments, demonstrating diversity rather than uniformity.
D: When using a mechanical lift is incomplete and lacks essential information about proper use, safety precautions, or benefits, rendering it an inaccurate or insufficient choice.
A caregiver who smokes marijuana while working may have a
Rationale:
A caregiver who smokes marijuana while working may have a substance abuse problem. This behavior indicates the misuse of drugs that can impair judgment, reduce work performance, and endanger patient safety. Substance abuse involves consuming substances in a manner that negatively affects professional responsibilities, making this the most accurate description of the caregiver’s problematic conduct during work hours.
A: Sober relapse This term refers to returning to substance use after a period of abstinence, but the question does not specify prior sobriety or relapse, so this option does not fit the scenario.
C: Legal substance appropriation This phrase implies lawful use or allocation of substances, which contradicts the caregiver’s inappropriate marijuana use during work, rendering this choice irrelevant.
D: Workplace harassment issue This involves improper behavior towards coworkers or clients, unrelated to substance use, making it unrelated to the caregiver’s marijuana consumption at work.
The nurse is caring for a postoperative patient who has had a minimally invasive carpel tunnel repair. The patient has a temperature of 97° F and is shivering. Which reason will the nurse most likely consider as the primary cause when planning care?
Rationale:
The patient’s temperature of 97° F and shivering most likely result from anesthesia lowering metabolism. Anesthesia reduces the body's metabolic rate, decreasing heat production and causing hypothermia, which leads to shivering as the body attempts to generate warmth. This is common after surgery, especially minimally invasive procedures, where external heat loss is minimal but metabolic suppression is significant.
B: Surgical suites having air currents may cause some heat loss, but this effect is minimal and less significant than metabolic reduction in causing postoperative hypothermia and shivering.
C: The patient being dressed only in a gown does not primarily explain the low temperature; clothing affects heat retention but anesthesia-induced metabolic changes are more influential.
D: A large open body cavity causes heat loss, but minimally invasive carpal tunnel repair involves small incisions, making this explanation irrelevant to the patient’s hypothermia.
A middle-aged man walks 2 miles each day. What type of exercise is he getting by this activity?
Rationale:
Walking 2 miles each day is an example of isotonic exercise.
Isotonic exercises involve muscle contractions with movement, where muscle length changes as tension remains constant, such as walking. This activity requires continuous movement and repetitive muscle contractions, fitting the definition of isotonic exercise perfectly by promoting endurance and cardiovascular health through dynamic motion.
B: Isometric exercises involve muscle contractions without any joint movement, unlike walking, which requires dynamic muscle length changes and bodily displacement.
C: Isokinetic exercises use specialized machines to maintain constant speed during muscle contraction, not applicable to natural walking activities.
D: Isostretching focuses on sustained stretching without muscle shortening or lengthening, differing fundamentally from walking’s repetitive muscle movement.
A sign of dehydration is
Rationale:
Dizziness is a sign of dehydration. Dizziness occurs because dehydration reduces blood volume, leading to decreased blood flow and oxygen supply to the brain. This lack of adequate circulation causes lightheadedness or vertigo, which are common symptoms indicating the body’s need for fluids to restore balance and maintain normal physiological functions, making dizziness a clear dehydration indicator.
A: Moist mucous membranes indicate proper hydration levels, as dehydration typically causes dry or sticky mucous membranes due to fluid loss, making moist membranes inconsistent with dehydration symptoms.
B: An increase in urinary output contradicts dehydration signs since fluid loss usually results in decreased urine production to conserve water within the body.
C: Slowed heartbeat does not align with dehydration, which often causes an increased heart rate as the body attempts to maintain adequate circulation despite lower blood volume.
Which of the following foods should be avoided by clients who are prone to
Rationale:
Clients prone to certain sensitivities should avoid chocolate. Chocolate contains compounds like caffeine and theobromine that can trigger allergic reactions, migraines, or digestive issues in sensitive individuals. Its stimulants and potential allergens often exacerbate symptoms, making it unsuitable for those prone to adverse responses. Avoiding chocolate helps minimize health risks and supports better symptom management in vulnerable clients.
A: Lettuce Lettuce is generally mild, hypoallergenic, and unlikely to provoke reactions in sensitive clients. It lacks stimulants or common allergens that would necessitate avoidance for those prone to sensitivities or adverse effects.
B: Eggs Eggs are a common allergen but do not contain stimulants like chocolate. Unless the client has a specific egg allergy, eggs are not typically avoided for sensitivity related to stimulants or migraine triggers.
D: Butterscotch Butterscotch is primarily sugar and butter-based without stimulants or strong allergens. It does not commonly provoke sensitivities related to migraine or allergic reactions, making it less critical to avoid compared to chocolate.
One way for a nursing assistant to make a positive first impression at a job interview is to
Rationale:
Bathe ensures cleanliness and personal hygiene, which are crucial for making a positive first impression at a job interview, especially in a healthcare setting where professionalism and attention to self-care are highly valued. Demonstrating good grooming habits reflects respect for the role and awareness of workplace standards, fostering trust and confidence in the nursing assistant’s suitability for the position.
B: Use deodorant and brush her teeth before the interview improves personal hygiene but lacks the comprehensive cleanliness impact that bathing provides, which significantly enhances overall appearance and scent control.
C: Put on a pleasant perfume or cologne before the interview might overwhelm or irritate others, potentially causing negative reactions in a healthcare environment where sensitivity to smells is important.
D: Smoke a cigarette right before the interview if it will help her to be calm introduces unpleasant odors and health risks, creating an unfavorable impression contrary to professional healthcare standards.
Which of the following is a sign or symptom of the beginning stages of HIV infection?
Rationale:
Flu-like symptoms are a sign or symptom of the beginning stages of HIV infection. Early HIV infection often causes symptoms similar to the flu, such as fever, sore throat, and fatigue, which occur as the immune system responds to the virus. These symptoms typically appear within 2 to 4 weeks after exposure, marking the acute phase of HIV.
A: Poor circulation does not typically manifest during early HIV infection; it is unrelated to initial viral activity and immune response in the acute stage.
B: Damage to the eyes usually occurs in advanced HIV or AIDS due to opportunistic infections, not in the initial infection phase.
C: Open sores on the penis are more characteristic of other sexually transmitted infections, not a primary sign of early HIV infection.
Care guidelines for dialysis include
Rationale:
Care guidelines for dialysis include following instructions for intake and output measurement carefully. Monitoring fluid balance through accurate intake and output documentation is essential to prevent complications such as fluid overload or dehydration, which can adversely affect dialysis effectiveness and patient health. Proper measurement ensures timely interventions and maintains overall treatment safety and efficacy during dialysis care.
A: Advising the resident to wear tight sleeves restricts blood flow and can damage the dialysis access site, increasing risk of complications and impairing treatment efficacy.
B: Checking blood pressure readings on the access arm risks injury to the vascular access, potentially causing clotting or damage and compromising dialysis function.
D: Encouraging residents to put pressure on the access arm can harm the access site, leading to bleeding or thrombosis, which jeopardizes dialysis access patency and patient safety.
Principle of triage for 27 seriously injured in an aircraft accident:
Rationale:
The principle of triage is to produce the greatest number of survivors based on available resources. This approach prioritizes efficient use of limited medical supplies and personnel, focusing on patients who have the best chance of survival rather than those who are most severely injured or first encountered, optimizing overall outcomes in mass casualty incidents like an aircraft accident.
A: Treat the most severely injured patients first prioritizes critical cases but may exhaust resources on those unlikely to survive, reducing overall survival rates in large-scale emergencies.
B: Establish a field triage area directed by a doctor is a logistical step but does not define the core principle guiding patient prioritization during triage.
C: Rapidly transport all patients to the nearest appropriate hospital overlooks resource constraints and triage priorities, potentially overwhelming facilities and limiting effective care distribution.
Your pediatric patient has been ill for several days leading you to suspect he may be dehydrated. Once on the electrocardiogram, it is evident the patient has an accelerated heart rate and abnormally flattened T waves. What is the most likely cause of this finding?
Rationale:
An abnormally flattened T wave combined with an accelerated heart rate most likely indicates hypokalemia. Hypokalemia commonly presents with ECG changes such as flattened or inverted T waves, along with tachycardia, especially in dehydrated patients due to electrolyte imbalances. This finding aligns with the clinical context of prolonged illness and dehydration, which can cause potassium depletion and cardiac electrical disturbances.
A: Hyperglycemia Hyperglycemia primarily affects glucose metabolism and rarely causes specific ECG changes like flattened T waves or tachycardia; it is more associated with symptoms like polyuria and polydipsia rather than direct cardiac electrical abnormalities.
B: Hyperkalemia Hyperkalemia typically causes peaked T waves and widened QRS complexes, opposite to flattened T waves, making it inconsistent with the patient’s ECG findings and clinical presentation.
C: Hypoglycemia Hypoglycemia influences neurological function and can cause symptoms like confusion or seizures, but it does not produce characteristic ECG changes such as flattened T waves or tachycardia in this context.
A 15 year old male is brought to the ED after being involved in a motor vehicle crash. He is unconscious and was intubated at the scene by emergency personnel. Upon arrival at the ED, the patient's oxygen saturation is 92%, HR is 96 bpm and BP is 150/85. Breath sounds are decreased on the left side of the thorax. The next step is:
Rationale:
The next step is to reassess the position of the endotracheal tube.
Reassessing the endotracheal tube is crucial because decreased breath sounds on one side can indicate tube malposition, such as right mainstem intubation. Correcting tube placement can rapidly improve oxygenation and ventilation, preventing unnecessary invasive procedures and addressing the primary cause of asymmetric breath sounds after intubation in trauma patients.
A: Immediate needle cricothyroidotomy is not indicated here since the airway is already secured by intubation, and there is no evidence of upper airway obstruction requiring emergency surgical airway.
C: Chest tube insertion is premature without confirming the cause of decreased breath sounds; tube malposition must be ruled out before invasive thoracic intervention.
D: Immediate needle thoracentesis is inappropriate because clinical signs do not confirm tension pneumothorax, and less invasive assessment should precede emergency decompression.
A 20 year old male is brought to the hospital approximately 30 minutes after being stabbed in the chest. There is a 3cm wound just medial to the left nipple. His BP is 70/33 and HR is 140. Neck and arm veins are distende Breath sounds are normal. Heart sounds are diminished, IV access has been established and warm crystalloid is infusing. The next most important aspect of immediate management is:
Rationale:
The next most important aspect of immediate management is a FAST exam.
A FAST exam rapidly evaluates for pericardial effusion or hemoperitoneum, crucial in trauma with hypotension and distended neck veins, suggesting possible cardiac tamponade. It is a bedside, non-invasive diagnostic tool guiding urgent intervention, outweighing delays from imaging or diagnostics not immediately informative in this unstable patient.
A: CT scan of the chest Delays critical bedside assessment and resuscitation in an unstable patient; CT is time-consuming and less practical when rapid diagnosis of tamponade is needed.
B: 12 lead ECG Provides electrical heart activity but does not identify life-threatening pericardial fluid accumulation causing shock in trauma.
D: Begin infusion of RBCs While blood transfusion is essential, immediate identification of tamponade via FAST directs lifesaving pericardial drainage before further resuscitation.
Which of the following is an example of objective information?
Rationale:
A resident's face is drooping on one side. This statement presents observable, measurable data that can be verified by anyone, making it objective information. It relies on visible facts without interpretation or personal feelings. Objective information is based on direct evidence, unlike subjective information which involves opinions, emotions, or personal experiences that vary between individuals.
B: A resident does not like his caregiver conveys personal feelings and opinions, which are subjective and cannot be independently verified through observation or measurement.
C: A resident enjoyed his breakfast reflects an individual’s personal experience and emotional response, representing subjective information that depends on the resident’s perception.
D: A resident does not want to go to religious services today expresses a choice influenced by feelings or preferences, thus it is subjective and not based on observable facts.
Your adult patient sustained a right index finger amputation at work. On arrival, first responders have the bleeding controlled with sterile dressings, and the patient is conscious, alert, and oriented. What is the best way to manage the patient's amputated finger during transport to the hospital?
Rationale:
The best way to manage the amputated finger is to wrap it in gauze moistened with normal saline, seal it in a plastic bag, and place it on ice. This method prevents tissue desiccation, reduces bacterial contamination, and preserves cellular viability by maintaining a cold, moist environment essential for successful replantation during transport to the hospital.
A: Do not wrapping the finger leaves it exposed to drying and contamination, increasing tissue damage and reducing the chances of successful reattachment. Simply placing it on a towel with ice is insufficient protection.
C: Rinsing the gauze-wrapped finger with water risks washing away protective saline and introduces contaminants. Direct contact with ice inside the bag without proper wrapping can cause frostbite and cellular injury.
D: Keeping the finger close to the patient’s body temperature risks accelerating tissue degradation. Warmth increases metabolic demand and necrosis, which diminishes the likelihood of successful surgical reattachment.
2 Which of the following is the first step in the nursing process?
Rationale:
The first step in the nursing process is Assessment. Assessment involves collecting comprehensive data about the patient's health status, including physical, psychological, and social factors. This foundational step enables nurses to identify health problems, establish baseline information, and develop a personalized plan of care. Without thorough assessment, subsequent steps like diagnosis and planning lack accurate information to be effective and targeted.
A: Diagnosis identifies patient problems but depends on data from the initial assessment; it cannot precede understanding the patient's condition.
C: Evaluation measures the effectiveness of interventions and outcomes, making it a later phase after planning and implementation.
D: Planning sets goals and strategies based on assessment and diagnosis; it requires prior data collection to be meaningful.
Which of the following is a function of the bones?
Rationale:
Bones lend support to body structures. Bones provide a rigid framework essential for maintaining the body’s shape and posture. They bear weight and allow muscles to attach, facilitating movement and structural integrity. This support function is fundamental to the skeletal system, enabling the body to maintain its form and perform physical activities efficiently and effectively.
A: Protecting the body from disease involves the immune system, not bones. Bones do not directly fight infections or guard against pathogens.
C: Sending messages throughout the human body is a function of the nervous system, not bones. Bones do not transmit electrical signals or nerve impulses.
D: Pumping blood throughout the body is the role of the heart, not bones. Bones do not contract or circulate blood in the circulatory system.
A form of cancer that begins in the uterus is called
Rationale:
A form of cancer that begins in the uterus is called Endometrial cancer. Endometrial cancer originates specifically from the lining of the uterus, known as the endometrium, distinguishing it from other reproductive cancers. Its development involves abnormal cell growth within this uterine lining, making it the precise medical term for uterine cancer, unlike cancers arising in nearby organs or tissues.
A: Cervical cancer Arises in the cervix, the lower part of the uterus, not the uterine lining. It involves different cells and symptoms, thus it does not represent cancer beginning specifically within the uterus itself.
B: Ovarian cancer Develops in the ovaries, which are separate reproductive organs responsible for egg production. This cancer type is unrelated to the uterine tissue and originates outside the uterus.
C: Testicular cancer Occurs exclusively in the testes, male reproductive organs, making it unrelated to the female reproductive system and the uterus. It cannot describe any form of uterine cancer.
The process of ____________ helps communities prevent disease.
Rationale:
Sanitation helps communities prevent disease. Sanitation involves maintaining clean conditions to promote health, such as proper waste disposal and clean water supply, which directly reduces disease transmission. It creates an environment that minimizes exposure to pathogens, thereby protecting public health and preventing outbreaks within communities by controlling factors that contribute to the spread of infections and illnesses.
A: Sterilization eliminates all forms of microbial life on instruments but does not address broader community health measures or environmental cleanliness necessary for disease prevention in populations.
C: Asepsis refers to techniques preventing contamination during medical procedures, focusing on cleanliness in clinical settings rather than widespread community disease prevention.
D: Immunity is the body's defense against pathogens but does not involve environmental or communal actions that prevent disease spread among populations.
What is transcultural nursing?
Rationale:
Transcultural nursing is the study of various cultures with the goal of providing care specific to each. This approach emphasizes understanding cultural differences to deliver personalized, respectful, and effective nursing care, ensuring patients' cultural beliefs, values, and practices are honored while promoting health and well-being in diverse populations.
B: Nursing that involves traveling to different countries focuses on geographical movement rather than cultural understanding or care, which transcultural nursing prioritizes.
C: Providing care to residents who are transgender addresses gender identity specifically, not the broader cultural competence central to transcultural nursing.
D: Nursing that involves a team approach centers on collaboration, differing from transcultural nursing’s emphasis on cultural sensitivity and individualized care.
How can an employer provide a safe working environment?
Rationale:
An employer can provide a safe working environment by providing training and personal equipment for an employee's job role. Proper training ensures employees understand safety protocols, while personal equipment protects them from hazards. This approach directly addresses workplace risks, reducing accidents and injuries, thereby fulfilling the employer's responsibility to maintain a secure and health-conscious workspace for all staff members.
B: Ask employees to provide their own personal protective equipment and clothing shifts responsibility to workers, potentially leading to inconsistent safety standards and unregulated protection, which undermines workplace safety protocols and employer accountability.
C: Provide employees with a paid lunch and break times to keep morale high improves comfort and satisfaction but does not directly address physical safety hazards or the provision of protective measures required in a secure work environment.
D: Provide travel arrangements to and from the workplace assists with commuting convenience but does not influence the safety conditions within the actual workplace, which is the employer’s primary responsibility to manage effectively.
_____ is a federal health insurance program for people who are 65 years of age or older or people of any age with permanent kidney failure or certain disabilities.
Rationale:
Medicare is a federal health insurance program for people who are 65 years of age or older or people of any age with permanent kidney failure or certain disabilities. Medicare specifically targets elderly and disabled populations, providing coverage for hospital care, medical services, and prescription drugs under federal oversight, distinguishing it clearly from other health or safety programs.
B: Medicaid provides health coverage primarily for low-income individuals and families, not specifically targeting elderly or disabled individuals based on age or kidney failure, and is jointly funded by state and federal governments.
C: Occupational Safety and Health Administration focuses on workplace safety regulations and standards, unrelated to providing health insurance or medical coverage for elderly or disabled individuals.
D: Health and Human Services is a federal department overseeing public health programs but does not itself provide a specific health insurance program like Medicare for elderly or disabled populations.
Diabetic ketoacidosis may be caused by
Rationale:
Diabetic ketoacidosis may be caused by having too much insulin in the body.
Having too much insulin disrupts normal glucose metabolism, leading to an imbalance that can trigger ketoacidosis by promoting excessive fat breakdown and ketone production, creating an acidic environment in the blood. This option accurately reflects the pathophysiological mechanism behind diabetic ketoacidosis.
B: Having too little insulin in the body typically results in hyperglycemia but does not directly cause ketoacidosis through the mechanisms described here.
C: Eating too little food alone does not induce diabetic ketoacidosis, as it lacks the hormonal imbalance necessary to produce ketones in excess.
D: Too much exercise can cause metabolic changes but is not a primary cause of diabetic ketoacidosis, which depends on insulin regulation.
Staff must report if a resident consumes less than _______ of his meal.
Rationale:
Staff must report if a resident consumes less than 50% of his meal.
Consuming less than half of a meal signals potential health or nutritional issues requiring staff intervention. Reporting at the 50% threshold ensures timely monitoring and prevents complications from insufficient intake. This standard balances vigilance with practicality, helping caregivers identify residents at risk without unnecessary alarm over minor consumption variations.
A: 75% sets a threshold too high, causing excessive reporting and unnecessary concern over minor meal reductions, diluting focus on serious nutritional risks.
C: 35% is too low, risking missed early warning signs of inadequate intake and delaying necessary care interventions, potentially jeopardizing resident health.
D: 80% demands reporting for very minor reductions, leading to impractical expectations and excessive workload with limited clinical benefit or relevance to resident well-being.
Why is the prompt reporting of defective equipment important in the workplace?
Rationale:
Prompt reporting of defective equipment is important to ensure that the risk to people's health and safety is minimised. This prevents accidents and injuries by allowing timely intervention, maintaining a safe work environment, and adhering to safety regulations. Early identification and reporting help address hazards before they escalate, protecting employees from potential harm and ensuring ongoing workplace safety compliance.
A: To ensure the equipment is replaced quickly so work can resume prioritizes productivity over safety, overlooking the primary concern of preventing health risks and safeguarding employees from harm.
C: To ensure the risk assessment process is completed quickly and efficiently focuses on procedural speed rather than the critical goal of reducing actual health and safety dangers.
D: To ensure the health and safety representative informs the manufacturer emphasizes communication with external parties instead of directly addressing the immediate health and safety risks posed by defective equipment.
A 29-year-old male is brought to the ED after being involved in a motor vehicular collision when his car struck a bridge abutment. He is intoxicated, has GCS 13, and complains of abdominal pain. His BP was 80mmHg systolic by palpation on admission, but rapidly increased to 110/70 with the administration of IV flui His heart rate is 120/min. The chest x-ray shows loss of aortic knob, widening of mediastinum, no rib fracture, and no hemopneumothorax. Contrast angiography:
Rationale:
Contrast angiography is not necessary if the CT-scan of the chest is normal.
CT angiography has become the preferred initial imaging modality for suspected traumatic aortic injury due to its high sensitivity and specificity. A normal CT scan effectively rules out significant aortic injury, making invasive contrast angiography redundant and unnecessary in stable patients without additional suspicious findings.
A: Is not indicated This is overly broad; contrast angiography may still be indicated in certain trauma cases depending on clinical suspicion and imaging results.
B: Should be performed after CT scan of the chest This is incorrect as CT angiography often replaces conventional contrast angiography, not follows it.
C: Is positive for aortic rupture in 80% of similar cases This exaggerates the sensitivity and does not reflect the current diagnostic standards or prevalence of positive findings.
Which number of respirations would be considered abnormal?
Rationale:
An abnormal number of respirations would be 22 breaths per minute.
22 breaths per minute exceeds the typical adult respiratory rate range of 12 to 20 breaths per minute, indicating tachypnea. This elevated rate suggests possible respiratory distress or an underlying medical condition requiring attention, distinguishing it as abnormal compared to normal resting breathing rates.
A: 17 breaths per minute falls within the normal adult respiratory rate range, representing a typical, healthy breathing pattern at rest.
C: 13 breaths per minute lies comfortably within the standard respiratory interval, indicating no deviation from normal breathing rates.
D: 12 breaths per minute represents the low boundary of normal adult respiratory rates, thus not constituting an irregular respiration count.
