When assessing a client with peripheral arterial disease, the nurse assesses the client for which of the following signs and symptoms that would be consistent with tissue ischemia?
Rationale:
Leg pain while walking is a sign and symptom consistent with tissue ischemia in peripheral arterial disease.
Correct Option Explanation:
Leg pain while walking, known as intermittent claudication, is a cardinal symptom
Which information from a patient helps the nurse confirm the previous diagnosis of chronic stable angina?
Rationale:
"The pain goes away after a nitroglycerin tablet" helps the nurse confirm the previous diagnosis of chronic stable angina.
Nitroglycerin is a potent vasodilator that rapidly relieves anginal pain by reducing myocardial oxygen demand and increasing coronary blood flow. Its consistent effectiveness in alleviating chest discomfort is a hallmark feature of chronic stable
A patient with diabetes mellitus and chronic stable angina has a new order for captopril . The nurse should teach the patient that the primary purpose of captopril is to
Rationale:
The primary purpose of captopril for this patient is to prevent changes in heart muscle.
Captopril, an ACE inhibitor, is prescribed for its cardioprotective effects. In patients with diabetes and angina, it significantly reduces cardiac remodeling and hypertrophy, preventing adverse structural changes in the heart muscle. This action helps preserve ventricular function and mitigates the progression of heart disease, offering crucial protection against long-term complications associated with both conditions.
A: decrease the heart rate. Captopril primarily acts on the renin-angiotensin system, not directly on heart rate. Beta-blockers are the class of medication typically prescribed to achieve a reduction in heart rate.
B: control blood glucose levels. Captopril is not an anti-diabetic medication; its primary mechanism does not involve directly regulating blood glucose. While beneficial for diabetic nephropathy, it does not manage glycemia itself.
D: reduce the frequency of chest pain. Captopril's main action is not directly anti-anginal. While improving cardiac function might indirectly help, nitrates or beta-blockers are typically used to acutely reduce angina frequency.
Which lifestyle changes should a client diagnosed with coronary artery disease consider?
Rationale:
Clients diagnosed with coronary artery disease should consider All of the Above lifestyle changes.
Smoking cessation significantly reduces cardiovascular risk. Regular exercise strengthens the heart and improves circulation. Weight reduction lessens the strain on the cardiovascular system and improves lipid profiles. Collectively, these lifestyle modifications are crucial for managing coronary artery disease, preventing disease progression, and enhancing overall cardiac health by addressing multiple risk factors simultaneously, leading to better long-term outcomes and reduced morbidity.
A: Smoking cessation is a vital component of managing CAD, yet focusing solely on this change neglects other equally critical interventions necessary for comprehensive disease management and risk factor mitigation.
B: Establishing a regular exercise routine profoundly benefits cardiac health and circulation. However, this single intervention alone is insufficient to address the multifaceted risk factors contributing to coronary artery disease effectively.
C: Weight reduction significantly alleviates cardiovascular strain and enhances metabolic health. While crucial, this isolated modification overlooks the combined impact of other essential lifestyle adjustments for comprehensive CAD management.
The client is being given a cardio-selective beta blocker because of which possible reasons? Select all that apply.
Rationale:
The client is being given a cardio-selective beta blocker because of Dysrhythmias.
Cardio-selective beta blockers primarily target beta-1 receptors in the heart, reducing heart rate and contractility. This action effectively stabilizes an irregular heart rhythm, making them a common treatment for various dysrhythmias. By slowing conduction through the AV node and decreasing myocardial excitability, these medications help restore a normal sinus rhythm and prevent dangerous arrhythmias, improving cardiac function.
A: Hypotension A cardio-selective beta blocker would worsen hypotension by further decreasing heart rate and contractility, leading to a dangerous drop in blood pressure rather than treating it.
B: Hypertension While beta blockers treat hypertension, the question asks for possible reasons for a cardio-selective beta blocker, and dysrhythmias are a more direct and specific indication for their cardio-selective action.
D: Cardiac arrest During cardiac arrest, the heart has stopped pumping effectively; a beta blocker would further suppress cardiac activity, making it contraindicated in this acute, life-threatening emergency.
After the AV node, the electrical impulse is then transmitted into the _________, and into the _________.
Rationale:
After the AV node, the electrical impulse is then transmitted into the Bundle of His, and into the Purkinje fibers.
The atrioventricular (AV) node delays the impulse briefly before it passes into the Bundle of His, also known as the AV bundle. This specialized conduction pathway then branches into left and right bundle branches, which further divide into the Purkinje fibers. These fibers rapidly distribute the electrical signal throughout the ventricular myocardium, ensuring synchronized ventricular contraction for efficient blood ejection.
A: Purkinje fibers, ventricles The impulse reaches the Purkinje fibers after the Bundle of His, not immediately post-AV node. The ventricles are stimulated by the Purkinje fibers, not a subsequent structure in the direct electrical conduction pathway.
B: Atria, ventricles The atria contract before the AV node receives the impulse; they are not part of the electrical pathway after it. While ventricles are eventually stimulated, this option omits crucial intermediate conduction structures.
D: Ventricles, Purkinje fibers The electrical impulse is conducted to the ventricles by the Purkinje fibers, not transmitted directly into the ventricles immediately after the AV node. The Bundle of His precedes Purkinje fibers in the specific sequence.
A nurse responds to a telemetry alarm and determines that the client is in which rhythm, where the rate is greater than 150, diastole is shortened, and the heart does not have sufficient time to fill?
Rationale:
The client is in Supraventricular Tachycardia.
Supraventricular Tachycardia (SVT) is characterized by a heart rate typically exceeding 150 bpm, originating above the ventric
Myocardial ischemia occurs as a result of increased oxygen demand and decreased oxygen supply. What factors and disorders result in increased oxygen demand (select all that apply)?
Rationale:
Increased cardiac workload with aortic stenosis results in increased oxygen demand.
Increased cardiac workload with aortic stenosis significantly elevates the heart's effort to pump blood against the narrowed valve. This heightened resistance and pressure overload force the myocardium to contract more forcefully and frequently, consuming more ATP and consequently requiring a greater supply of oxygen to sustain its metabolic activity and maintain function.
A: Hypovolemia or anemia primarily reduce oxygen supply to the myocardium by decreasing blood volume or oxygen-carrying capacity. These conditions do not directly cause the heart muscle to increase its workload or oxygen consumption.
C: Narrowed coronary arteries from atherosclerosis directly impair oxygen supply to the heart muscle by physically obstructing blood flow. This condition limits the delivery of oxygen, rather than increasing the myocardium's need for it.
D: Angina in the patient with atherosclerotic coronary arteries is a symptom of myocardial ischemia, often triggered when existing limited supply cannot meet demand. Angina itself is not a factor that increases the heart's oxygen demand.
The client has an IV and is experiencing tissue necrosis at the site of the IV. What drug might be causing this?
Rationale:
An alpha agonist might be causing tissue necrosis at the IV site.
Alpha agonists, like norepinephrine or dopamine, cause intense vasoconstriction by stimulating alpha-1 receptors on blood vessels. This profound narrowing of blood vessels significantly reduces blood flow to the surrounding tissue, leading to ischemia. Prolonged ischemia deprives cells of oxygen and nutrients, ultimately resulting in cellular death and observable tissue necrosis at the IV insertion site.
A: Digoxin Digoxin primarily impacts cardiac contractility and rhythm, not directly causing localized tissue necrosis through vasoconstriction at an IV site. Its effects are systemic, related to heart muscle function.
C: A beta blocker Beta blockers, such as metoprolol, primarily reduce heart rate and blood pressure by blocking beta-adrenergic receptors. They do not induce the localized intense vasoconstriction necessary for IV site tissue necrosis.
D: A calcium channel blocker Calcium channel blockers, like amlodipine, relax blood vessels and reduce heart rate, often used for hypertension. They vasodilate rather than constrict, making tissue necrosis at an IV site an unlikely direct consequence.
Which type of heart valve disease occurs when the mitral valve does not close properly, allowing blood to flow backward into the left atrium?
Rationale:
Mitral regurgitation occurs when the mitral valve does not close properly, allowing blood to flow backward into the left atrium.
Mitral regurgitation accurately describes the condition where the mitral valve fails to close completely
After the nurse teaches the patient about the use of carvedilol (Coreg) in preventing anginal episodes, which statement by a patient indicates that the teaching has been effective?
Rationale:
It is important not to suddenly stop taking the carvedilol.
Beta-blockers like carvedilol should not be abruptly discontinued due to the risk of rebound angina, myocardial infarction, or arrhythmias. Sudden cessation can lead to increased heart rate and blood pressure, exacerbating cardiac symptoms. Patients must understand the importance of gradual tapering under medical supervision to prevent adverse cardiovascular events, indicating effective teaching about safe medication management.
A: “Carvedilol will help my heart muscle work harder.†Carvedilol, a beta-blocker, actually reduces the heart's workload and oxygen demand, thereby decreasing angina. It does not make the heart muscle work harder, but rather slows heart rate and lowers blood pressure.
C: “I can expect to feel short of breath when taking carvedilol.†While carvedilol can cause bronchospasm in susceptible individuals, it is not an expected or desired effect.
The nurse is caring for a client on warfarin with an INR of 5.2. What is the most appropriate action?
Rationale:
Administer vitamin K as an antidote is the most appropriate action.
An INR of 5.2 is significantly above the therapeutic range (typically 2.0-3.0) for a client on warfarin, indicating a high risk of bleeding. Administering vitamin K directly reverses warfarin's anticoagulant effects by promoting the synthesis of clotting factors. This intervention swiftly reduces the elevated INR, mitigating the immediate danger of hemorrhage and restoring safer coagulation levels for the client.
B: Hold the next dose of warfarin. While holding the dose is part of managing an elevated INR, it acts too slowly for a dangerously high INR of 5.2, which demands immediate reversal.
C: Increase the dose of warfarin. Increasing the dose would dangerously escalate the client's anticoagulation, further elevating the INR and intensifying their already critical bleeding risk.
D: Monitor the client's INR closely. Close monitoring alone is insufficient for an INR of 5.2; immediate pharmacological intervention is required to prevent serious bleeding complications.
Which type of medication helps to lower cholesterol levels in the blood?
Rationale:
Statins help to lower cholesterol levels in the blood.
Statins are a class of drugs that reduce cholesterol production in the liver by inhibiting the enzyme HMG-CoA reductase. This action significantly lowers low-density lipoprotein (LDL) cholesterol, often called "bad" cholesterol, and triglycerides, while sometimes increasing high-density lipoprotein (HDL) cholesterol. Their primary therapeutic role is preventing cardiovascular disease by managing dyslipidemia effectively.
B: Beta-blockers Beta-blockers primarily reduce heart rate and blood pressure by blocking adrenaline's effects, not directly influencing blood cholesterol concentrations.
C: ACE inhibitors ACE inhibitors relax blood vessels and lower blood pressure by blocking the production of angiotensin II, having no direct impact on lipid profiles.
D: Diuretics Diuretics increase urine output to reduce fluid retention and blood pressure, rather than targeting or modifying circulating cholesterol levels in the bloodstream.
Which nursing diagnosis is most appropriate for a patient with chronic venous insufficiency?
Rationale:
Skin Integrity, impaired is the most appropriate nursing diagnosis for a patient with chronic venous insufficiency.
Chronic venous insufficiency (CVI) characteristically leads to venous stasis, causing blood pooling and increased pressure in lower extremity veins. This persistent pressure compromises tissue perfusion and nutrient exchange, leading to skin changes such as edema, hyperpigmentation, and ultimately, ulcer formation. These manifestations directly indicate a compromised dermal barrier and impaired skin integrity, making it a primary and direct consequence of CVI.
A: Activity Intolerance While CVI symptoms like leg pain and swelling can limit activity, activity intolerance is a secondary effect, not the primary, direct physical manifestation of the underlying pathophysiology on a tissue level.
B: Body Image, disturbed CVI-related skin changes, like discoloration or ulcers, can certainly affect self-perception. However, this diagnosis addresses a psychosocial response, not the direct physiological tissue damage characteristic of the condition.
C: Fluid Volume, deficient Chronic venous insufficiency involves fluid retention and pooling in the lower extremities due to incompetent valves, not a systemic lack of fluid volume or dehydration within the vascular system.
The client on warfarin has an INR of 1.2. What is the nurse's priority action?
Rationale:
Increasing the dose of warfarin is the nurse's priority action.
An INR of 1.2 indicates subtherapeutic anticoagulation for a client on warfarin, whose target range is typically 2.0-3.0. This low INR means the medication is not sufficiently preventing blood clot formation, increasing the patient's risk for thromboembolic events. The priority is to adjust the warfarin dose upwards to achieve the desired therapeutic INR and ensure adequate anticoagulation.
B: Administer vitamin K: Administering vitamin K would counteract warfarin's effects, further reducing anticoagulation and elevating the risk of dangerous clotting in a patient already subtherapeutic.
C: Monitor for signs of bleeding: A subtherapeutic INR of 1.2 primarily signifies an elevated risk of clot formation, not bleeding. While general patient safety always includes monitoring, it does not address the immediate pharmacological imbalance.
D: Hold the next dose and notify the healthcare provider: Holding the next dose would worsen the subtherapeutic state, significantly increasing the client's risk for thromboembolic events. The immediate need is dose escalation, not cessation.
The client is on a cardio-selective beta blocker. Why might this be ordered?
Rationale:
The client has asthma that would be exacerbated by a non-cardio-selective beta blocker.
Cardio-selective beta blockers primarily target beta-1 receptors in the heart, minimizing effects on beta-2 receptors in the lungs. For clients with asthma, non-selective beta blockers can block pulmonary beta-2 receptors, leading to bronchoconstriction and worsening respiratory function. Therefore, a cardio-selective agent is crucial to manage cardiac conditions while preventing severe asthma exacerbations, ensuring safer treatment for individuals with co-existing
A client reports substernal chest pain. Test results show electrocardiographic changes and an elevated cardiac troponin level. What should be the focus of nursing care?
Rationale:
Improving myocardial oxygenation and reducing cardiac workload should be the focus of nursing care.
Given substernal chest pain, ECG changes, and elevated troponin, the client is experiencing myocardial ischemia. Nursing care must prioritize re-establishing the balance between myocardial
From where do these originate, behind the cusps of the aortic valve, in an area known as Valsalva's sinus?
Rationale:
The structures originate behind the cusps of the aortic valve, in an area known as Valsalva's sinus.
The question explicitly states that the origin is "behind the cusps of the aortic valve, in an area known as Valsalva's sinus." This anatomical description directly points to the aortic valve as the source. The coronary arteries, supplying blood to the heart muscle, typically arise from the aortic sinuses, which are the dilatations behind the aortic valve leaflets, confirming this location.
A: Pulmonary valve This valve separates the right ventricle from the pulmonary artery, directing deoxygenated blood to the lungs, not containing the specified origin point for coronary arteries behind its cusps.
C: Tricuspid valve This valve resides between the right atrium and right ventricle, regulating deoxygenated blood flow within the right side of the heart, anatomically distant from Valsalva's sinus.
D: Mitral valve Located between the left atrium and left ventricle, this valve manages oxygenated blood flow into the left ventricle, bearing no anatomical relation to the aortic valve's sinuses or coronary artery origins.
The client is on digoxin and has severe digoxin toxicity. What is the nursing priority action?
Rationale:
Give Digibind as an antidote is the nursing priority action for severe digoxin toxicity.
For severe digoxin toxicity, administering Digibind (digoxin immune Fab) is the immediate priority. Digibind specifically binds to digoxin molecules in the blood, neutralizing their effects and rapidly reversing life-threatening symptoms. This targeted pharmacological intervention is crucial to prevent further cardiac complications and ensure patient stabilization when toxicity is severe and potentially fatal.
A: Check the potassium level. This is important, but not the priority action for severe toxicity where an antidote is available. Checking levels is diagnostic, not immediately therapeutic for acute, severe poisoning.
C: Change the dosing of digoxin to every other day. Adjusting future dosing is inappropriate for an acute, severe toxic event. The immediate concern is neutralizing the current overdose, not modifying the maintenance regimen for ongoing therapy.
D: Administer a potassium supplement to decrease digoxin toxicity. While hypokalemia can exacerbate toxicity, administering potassium is not the primary intervention for
The nurse is giving a client an IV bolus of heparin. What is the most important nursing action?
Rationale:
Monitoring the client's heart rate is the most important nursing action when giving an IV bolus of heparin.
Heparin, especially via IV bolus, can cause rapid changes, including hypersensitivity reactions or potential arrhythmias, which manifest as heart rate alterations. Close cardiac monitoring is crucial for early detection of adverse effects like tachycardia or bradycardia, ensuring immediate intervention to maintain optimal hemodynamic stability during this critical medication administration.
B: Check the client's blood pressure. While important, blood pressure changes often follow heart rate alterations in an acute reaction. Heart rate provides an earlier, more sensitive indicator of the body's immediate physiological response to the heparin bolus.
C: Check for signs of bleeding. Bleeding is a significant long-term risk of heparin therapy, but an IV bolus itself doesn't cause immediate, acute bleeding that would be the most pressing concern during administration. The immediate physiological response is paramount.
D: Monitor the client's respiratory rate. Respiratory rate monitoring is standard, but it's generally a less immediate or specific indicator of acute adverse reactions to an IV heparin bolus compared to cardiac changes. Heart rate offers a more direct physiological insight.
The client has had heparin-induced thrombocytopenia. How is this treated?
Rationale:
Heparin-induced thrombocytopenia is treated by giving lepirudin.
Heparin-induced thrombocytopenia (HIT) causes a paradoxical prothrombotic state despite low platelets, necessitating non-heparin anticoagulation. Direct thrombin inhibitors like lepirudin, a recombinant hirudin, are the cornerstone of acute HIT management. Lepirudin directly inhibits thrombin activity, preventing further clot formation and allowing platelet counts to normalize, thereby mitigating the severe thrombotic complications associated with HIT without using heparin products.
A: Give clotting factors. Clotting factors would worsen the underlying hypercoagulable state of HIT, where pathological thrombosis, not bleeding, is the critical concern needing immediate management.
B: Give vitamin K. Vitamin K promotes the synthesis of clotting factors, which would inappropriately increase the client's clotting potential in a condition already marked by dangerous thrombosis.
C: Give warfarin. Warfarin is contraindicated in acute HIT because it can induce warfarin-induced skin necrosis by transiently reducing protein C levels, exacerbating the prothrombotic condition.
A client on spironolactone (Aldactone) has a potassium level of 6.0 mEq/L. What is the nurse's priority action?
Rationale:
Hold the spironolactone and notify the healthcare provider.
Spironolactone is a potassium-sparing diuretic, making hyperkalemia (potassium > 5.0 mEq/L) a serious adverse effect. A potassium level of 6.0 mEq/L indicates significant hyperkalemia, posing a risk for cardiac dysrhythmias. Holding the medication immediately prevents further potassium retention. Notifying the healthcare provider ensures prompt assessment, diagnostic evaluation, and initiation of appropriate interventions to manage this life-threatening electrolyte imbalance.
B: Administer a potassium supplement. Administering additional potassium would dangerously elevate the existing severe hyperkalemia (6.0 mEq/L), significantly increasing the risk of fatal cardiac arrhythmias. This action directly contradicts safe patient care.
C: Continue the spironolactone as ordered. Continuing the medication would further promote potassium retention, exacerbating the already elevated and dangerous serum potassium level. This inaction disregards a critical adverse effect, jeopardizing patient safety and cardiac stability.
D: Increase the dose of spironolactone. Increasing the spironolactone dose would intensify the drug's potassium-sparing effects, critically worsening the client's hyperkalemia. This action could precipitate severe cardiac complications, making it a highly inappropriate and harmful intervention.
Pneumothorax symptoms.
Rationale:
Both A and B are symptoms of pneumothorax.
Pneumothorax, characterized by air accumulating in the pleural space, typically manifests with acute onset symptoms. Both chest pain, often sharp and pleuritic, and shortness of breath, varying from mild dyspnea to severe respiratory distress depending on lung collapse extent, are classic indicators. These combined presentations necessitate prompt medical evaluation to prevent further respiratory compromise and ensure effective treatment.
A: Chest pain While a primary symptom of pneumothorax, it does not encompass the full clinical picture, as respiratory distress is also a hallmark manifestation frequently accompanying thoracic discomfort.
B: Shortness of breath Though a significant symptom of pneumothorax, it alone does not represent the complete symptomatic profile, as patients often concurrently experience sudden, sharp chest discomfort alongside breathing difficulties.
D: None of the above This choice is incorrect because both chest pain and shortness of breath are well-established and frequently observed clinical indicators directly associated with the presence of a pneumothorax.
The client is receiving a beta agonist. What adverse effect should the nurse look out for?
Rationale:
The nurse should look out for Hyperglycemia.
Beta agonists, particularly beta-2 agonists, stimulate beta-2 receptors, which can lead to increased glycogenolysis in the liver and muscle, and gluconeogenesis. This process elevates blood glucose levels, causing hyperglycemia. Nurses must monitor blood sugar, especially in diabetic patients, to prevent significant metabolic disturbances due to this common pharmacological effect.
A: Hypoglycemia Hypoglycemia is not a typical adverse effect of beta agonists; these medications generally increase blood glucose, not decrease it. Beta-blockers, conversely, can mask the signs of hypoglycemia.
C: Muscle weakness Muscle weakness is not a direct or common adverse effect of beta agonists; instead, these drugs can sometimes cause muscle tremors due to receptor stimulation, which is distinct from generalized weakness.
D: Parasthesias Paresthesias, characterized by tingling or numbness, are not a recognized or frequent side effect associated with beta agonist administration. These neurological sensations are generally unrelated to the drug's primary mechanism of action.
The nurse is monitoring a client on dobutamine. What adverse effect should the nurse watch for?
Rationale:
Tachycardia is an adverse effect the nurse should watch for when monitoring a client on dobutamine.
Dobutamine is a beta-1 adrenergic agonist primarily used to increase myocardial contractility and stroke volume in heart failure. Its therapeutic action can inadvertently stimulate cardiac beta-1 receptors excessively, leading to an elevated heart rate. While improving cardiac output, this heightened chronotropic effect manifests as tachycardia, necessitating careful monitoring to prevent myocardial ischemia or arrhythmias, especially in vulnerable clients.
B: Bradycardia Dobutamine's mechanism of action involves stimulating beta-1 receptors, which directly increases heart rate, making a slow heart rate an unlikely adverse effect.
C: Hypertension Dobutamine primarily improves cardiac output without significant peripheral vasoconstriction; therefore, it typically causes minimal changes in blood pressure or even slight hypotension.
D: Respiratory distress Dobutamine specifically targets cardiac receptors, not directly influencing pulmonary function or airway patency, so respiratory distress is not a direct adverse effect.
A client has developed acute pulmonary edema. Which test result should the nurse expect?
Rationale:
Interstitial edema by chest X-ray should be the expected test result for a client with acute pulmonary edema.
Acute pulmonary edema involves fluid accumulation in the lung interstitium and alveoli. A chest X-ray visually confirms this pathological fluid shift, manifesting as increased vascular markings, peribronchial cuffing, and Kerley B lines, which are all characteristic signs of interstitial edema. This diagnostic finding directly correlates with the clinical presentation of pulmonary edema, providing definitive radiological evidence of the condition's severity and location.
B: Metabolic alkalosis by ABG analysis Acute pulmonary edema typically causes hypoxemia and respiratory acidosis due to impaired gas exchange and CO2 retention, not metabolic alkalosis.
C: Bradycardia by ECG Patients experiencing acute pulmonary edema often exhibit tachycardia as a compensatory mechanism for decreased cardiac output and increased sympathetic nervous system activation, not bradycardia.
D: Decreased PAWP by hemodynamic monitoring Acute pulmonary edema results from elevated left ventricular filling pressures, leading to increased pulmonary artery wedge pressure (PAWP), indicating fluid overload and cardiac dysfunction, not a decrease.
A primary prevention for reducing a female patient's risk of developing coronary heart disease is to:
Rationale:
A primary prevention for reducing a female patient's risk of developing coronary heart disease is to take aspirin 81 mg/d.
Aspirin 81 mg daily can serve as primary prevention by inhibiting platelet aggregation, thereby reducing the risk of thrombotic events that contribute to coronary heart disease development. For select women at elevated risk, particularly those with increased atherosclerotic cardiovascular disease risk factors but without a history of cardiovascular events, low
A toddler requires supplemental oxygen therapy for a cyanotic heart defect. In planning for home care, the nurse would discuss which of the following with the parents?
Rationale:
The nurse would discuss means of promoting mobility while meeting the need for supplemental oxygen.
Toddlers naturally explore and develop through movement, so maintaining age-appropriate activity is crucial for their physical and psychosocial well-being, even with a cyanotic heart defect requiring oxygen. Discussing adaptive equipment like portable oxygen tanks or long tubing allows the child to engage in typical developmental play and exploration, fostering independence and growth within the home environment while ensuring continuous oxygen delivery.
A: The need to maintain the child on bedrest. Bedrest severely restricts a toddler's essential developmental exploration and physical activity, which is generally contraindicated unless medically emergent, hindering their crucial gross motor skill acquisition and psychosocial development.
C: Symptoms of oxygen toxicity. While oxygen toxicity is a concern in specific clinical settings, it is less common with low-flow home oxygen for chronic conditions; the primary home care focus is safe administration and developmental support.
D: How to draw blood for blood gases. Drawing arterial blood gases is an advanced, invasive procedure performed by trained medical professionals, not a skill taught to parents for routine home management of supplemental oxygen.
A patient who is in the 10th week of outpatient cardiac rehabilitation continues to exhibit symptoms of depression. When developing a discharge plan, the cardiac-vascular nurse includes:
Rationale:
A referral for counseling and possible medication is included in the discharge plan for a patient exhibiting persistent depression symptoms.
The patient's ongoing depression at week 10 of cardiac rehabilitation necessitates a specialized intervention beyond the scope of typical cardiac rehab. Persistent depressive symptoms warrant professional psychological evaluation and potential pharmacological management. A referral ensures comprehensive mental health support, addressing the comorbidity effectively and promoting holistic recovery, which significantly impacts cardiac outcomes and overall well-being.
B: a trial of herbal remedies. Herbal remedies lack sufficient evidence-based efficacy for clinical depression and may interact adversely with cardiac medications. Recommending unproven treatments deviates from professional nursing standards and could delay effective care for the patient's persistent symptoms.
C: alternative therapies, including yoga and massage. While beneficial for stress reduction, yoga and massage are complementary therapies, not primary treatments for clinical depression. Relying solely on these approaches would neglect the patient's significant mental health needs, requiring more targeted, evidence-based interventions.
D: comprehensive information about the patient's cardiac status to help reduce their anxiety. Providing cardiac information primarily addresses anxiety, not the patient's diagnosed and persistent depression. Depression requires specific mental health interventions, and while information is helpful, it won't resolve underlying depressive symptoms requiring clinical management.
A child has been diagnosed with rheumatic fever. Which statement by the mother indicates an understanding of rheumatic fever?
Rationale:
"I should avoid giving my child aspirin for the arthritic pain." indicates the mother's understanding of rheumatic fever.
Rheumatic fever treatment often involves salicylates like aspirin for inflammation, but Reye's syndrome risk in children, especially with viral illnesses, makes non-aspirin anti-inflammatory drugs or corticosteroids safer alternatives. A mother understanding aspirin avoidance demonstrates awareness of potential complications and appropriate medication choices for her child's specific condition, prioritizing safety over symptomatic relief alone.
B: "It's very upsetting that my child must take penicillin until he's 20 years old." Rheumatic fever prophylaxis duration varies based on residual heart disease, often extending into adulthood, but not necessarily until age 20 for all cases. The specific age is not universally fixed for every child.
C: "I need to wear a gown, gloves, and
