Which clinical finding is most indicative of left-sided heart failure?
Peripheral edema
Hepatomegaly
Jugular venous distention
Pulmonary crackles
Left-sided heart failure leads to backup of blood into the pulmonary circulation, causing fluid accumulation in the lungs and resulting in crackles on auscultation. Jugular venous distention and hepatomegaly are more characteristic of right-sided failure. Peripheral edema can occur in both but is more pronounced in right-sided failure. American Heart Association
An ejection fraction of 35% in a patient with heart failure indicates which type of dysfunction?
HF with preserved EF (HFpEF)
Right-sided heart failure
HF with reduced EF (HFrEF)
High-output heart failure
An ejection fraction below 40% is consistent with systolic dysfunction, also called heart failure with reduced ejection fraction (HFrEF). HFpEF is defined by an EF of 50% or greater. High-output and right-sided heart failure have different pathophysiology and EF ranges. Circulation Journal
Which natriuretic peptide is most useful as a biomarker for diagnosing heart failure?
C-type natriuretic peptide (CNP)
Urodilatin
Atrial natriuretic peptide (ANP)
B-type natriuretic peptide (BNP)
B-type natriuretic peptide (BNP) is released by ventricular myocytes in response to increased wall stretch and is a sensitive marker for heart failure. ANP is released by the atria and is less specific. CNP and urodilatin have minimal diagnostic utility in clinical heart failure. NCBI PMC
Which class of medication is recommended as first-line therapy to reduce mortality in chronic heart failure?
Angiotensin-converting enzyme inhibitors (ACE inhibitors)
Digoxin
Calcium channel blockers
Alpha-adrenergic blockers
ACE inhibitors decrease afterload and inhibit the renin-angiotensin-aldosterone system, improving symptoms and survival in heart failure patients. Digoxin can improve symptoms but does not reduce mortality. Calcium channel blockers and alpha-blockers are not first-line for reducing mortality in heart failure. American Heart Association
What is the most common cause of right-sided heart failure in clinical practice?
Tricuspid regurgitation
Rheumatic heart disease
Pulmonary embolism
Left-sided heart failure
Right-sided heart failure most often stems from left-sided failure; increased pressure in the left atrium and pulmonary circulation leads to right ventricular overload. Primary right-sided causes like tricuspid regurgitation or pulmonary embolism are less common. NCBI Bookshelf
A patient on digoxin therapy reports seeing green halos around lights. This visual change is an early sign of which condition?
Digoxin toxicity
Hyperkalemia
Hypokalemia
Beta-blocker overdose
Visual disturbances such as yellow-green halos are classic early signs of digoxin toxicity. Monitoring digoxin levels and electrolytes, especially potassium, is essential to prevent toxicity. Hyper- or hypokalemia can predispose but the halo vision is specific to digoxin. UpToDate
A pulmonary capillary wedge pressure (PCWP) reading of 20 mm Hg in a heart failure patient indicates:
Normal left heart filling pressures
Right atrial overload
Elevated left atrial pressure and risk for pulmonary edema
Hypovolemia
PCWP approximates left atrial pressure; values above 18 mm Hg suggest elevated filling pressures and a high risk for pulmonary congestion. Hypovolemia would show low PCWP. Right atrial overload is assessed via right atrial pressure, not wedge pressure. Circulation
Which dietary modification is most appropriate for a patient with chronic heart failure?
High-fat diet
Low-sodium diet
Low-carbohydrate diet
High-protein diet
A low-sodium diet helps reduce fluid retention and decreases preload in heart failure patients. High-fat or high-protein diets do not address volume status. Sodium restriction is a cornerstone of nonpharmacologic management. ACC
Loop diuretics such as furosemide reduce preload by inhibiting a co-transporter located in which part of the nephron?
Collecting duct
Thick ascending limb of Henle
Proximal convoluted tubule
Distal convoluted tubule
Loop diuretics inhibit the Na?/K?/2Cl? co-transporter in the thick ascending limb of Henle, leading to significant diuresis and reduction in preload. Thiazides act on the distal convoluted tubule, and carbonic anhydrase inhibitors in the proximal tubule. Physiology Review
An ejection fraction of 55% in a patient with heart failure symptoms suggests which diagnosis?
High-output heart failure
Heart failure with preserved ejection fraction (HFpEF)
Right-sided heart failure
Heart failure with reduced ejection fraction (HFrEF)
An EF of 50% or greater in the presence of heart failure symptoms defines HFpEF, where diastolic dysfunction is the primary issue. HFrEF is diagnosed when EF is below 40%. Right-sided failure is characterized by systemic congestion rather than EF metrics. NCBI PMC
Which measurement is most useful to differentiate between systolic and diastolic heart failure?
Central venous pressure
Ejection fraction on echocardiogram
Serum BUN levels
Cardiac index
Systolic dysfunction is characterized by a reduced ejection fraction (EF), whereas diastolic dysfunction typically has a preserved EF. Cardiac index and central venous pressure do not distinguish systolic versus diastolic mechanisms. Serum BUN is a marker of renal perfusion, not ventricular function type. NCBI PMC
When initiating spironolactone therapy in heart failure, which laboratory value requires close monitoring?
Serum calcium
Serum chloride
Serum potassium
Serum sodium
Spironolactone is a potassium-sparing diuretic that antagonizes aldosterone, increasing the risk of hyperkalemia. Monitoring serum potassium is essential to avoid dangerous elevations. Sodium, calcium, and chloride are less directly affected. UpToDate
A patient on high-dose furosemide presents with muscle cramps and palpitations. Laboratory tests reveal an electrolyte abnormality responsible for these symptoms. Which is it?
Hyponatremia
Hypernatremia
Hypokalemia
Hypercalcemia
Loop diuretics cause significant potassium loss, leading to hypokalemia, which presents with muscle cramps, weakness, and palpitations. Sodium and calcium disturbances are less likely to produce these specific symptoms. Mayo Clinic
Which neurohormone is most directly responsible for pathological ventricular remodeling in chronic heart failure?
Angiotensin II
Nitric oxide
Bradykinin
Natriuretic peptides
Angiotensin II stimulates myocardial fibrosis and hypertrophy, driving adverse ventricular remodeling in chronic heart failure. Natriuretic peptides and nitric oxide counteract remodeling, and bradykinin has vasodilatory effects. NCBI PMC
In primary (AL) amyloidosis causing restrictive cardiomyopathy, which protein is deposited in the myocardium?
Beta-amyloid peptide
Collagen type I
Immunoglobulin light chains
Transthyretin
Primary amyloidosis (AL) is characterized by deposition of immunoglobulin light chains (lambda or kappa) in various tissues, including the myocardium, leading to restrictive physiology. Transthyretin is involved in ATTR amyloidosis, and beta-amyloid is linked to Alzheimer's disease. Circulation: Heart Failure

Study Outcomes

  1. Analyze heart failure pathophysiology -

    Differentiate between left-sided, right-sided, and congestive heart failure by recognizing underlying mechanisms and clinical manifestations presented in NCLEX-style questions.

  2. Apply nursing interventions for congestive heart failure -

    Identify appropriate prioritization, monitoring parameters, and treatment strategies to manage fluid overload and improve patient outcomes.

  3. Interpret cardiomyopathy variations -

    Distinguish between dilated, hypertrophic, and restrictive cardiomyopathy and outline specific nursing care considerations for each type.

  4. Assess diagnostic findings and lab values -

    Evaluate key laboratory results (e.g., BNP, electrolytes) and diagnostic tests (e.g., echocardiogram) to inform patient care decisions during the NCLEX exam.

  5. Evaluate pharmacological treatments -

    Explain the mechanisms, side effects, and nursing implications of common heart failure medications, including ACE inhibitors, beta-blockers, and diuretics.

  6. Develop test-taking strategies for NCLEX questions -

    Apply critical thinking techniques and question analysis tips to improve accuracy and confidence when tackling heart failure NCLEX questions.

Cheat Sheet

  1. Systolic vs Diastolic Dysfunction -

    Understand that systolic heart failure features reduced ejection fraction (EF < 40%) while diastolic preserves EF (> 50%) by impaired filling. Use the formula EF = SV/EDV×100 to calculate ejection fraction and remember "SIDs" to recall Systolic is ↓EF. This distinction often pops up in Heart Failure NCLEX Questions to guide appropriate treatment.

  2. NYHA Functional Classification -

    Familiarize with the four classes I - IV based on symptom severity and activity tolerance: Class I is no limitation, while Class IV has symptoms at rest. The mnemonic "I Need My Rest" (I-no Restriction, II-slight, III-marked, IV-rest) helps with Congestive Heart Failure NCLEX Questions. Accurate classification informs prognosis and medication adjustments per ACC/AHA guidelines.

  3. Cornerstone Pharmacotherapy (ABCs) -

    ACE inhibitors, Beta-blockers, and diuretics reduce morbidity and mortality by lowering preload, afterload, and preventing remodeling. Remember the "ABCs" of CHF management: ACEI like lisinopril, Beta-blockers like metoprolol, and loop diuretics like furosemide for volume control. These are high-yield for Heart Failure Questions NCLEX to select first-line agents.

  4. Acute Decompensated Management (LMNOP) -

    Use the mnemonic LMNOP (Lasix, Morphine, Nitrates, Oxygen, Position) for rapid stabilization of acute pulmonary edema. IV loop diuretics and vasodilators reduce preload while upright positioning and supplemental oxygen improve gas exchange. Expect NCLEX Questions About Heart Failure to test this protocol in emergency scenarios.

  5. Cardiomyopathy Differentiation -

    Distinguish dilated (systolic dysfunction, enlarged chambers), hypertrophic (diastolic dysfunction, thick walls), and restrictive (rigid ventricles) types using echo findings. The "D-H-R" mnemonic aids recall - Dilated, Hypertrophic, Restrictive - and guides cardiomyopathy NCLEX Questions on tailored management. Each subtype has unique treatment pathways per Journal of Cardiac Failure reviews.
