#1
Which of the following is a common symptom of heart failure?
Weight gain
ExplanationRetention of fluid leading to increased body weight.
#2
What is the primary cause of left-sided heart failure?
Coronary artery disease
ExplanationImpaired blood flow to the heart muscle due to blocked arteries.
#3
Which of the following is NOT a clinical manifestation of right-sided heart failure?
Dyspnea on exertion
ExplanationBreathlessness during physical activity is more common in left-sided heart failure.
#4
What diagnostic test is commonly used to assess the ejection fraction in heart failure?
Echocardiogram
ExplanationUltrasound imaging to measure heart function and ejection fraction.
#5
What is the hallmark symptom of acute decompensated heart failure?
Severe dyspnea
ExplanationSudden onset of severe difficulty in breathing.
#6
Which medication is commonly used as a first-line treatment for heart failure with reduced ejection fraction (HFrEF)?
Metoprolol
ExplanationBeta-blocker that reduces strain on the heart and improves function.
#7
Which classification system is commonly used to stage heart failure based on symptoms and functional limitations?
NYHA Functional Classification
ExplanationGrading system based on how much heart failure affects daily life.
#8
What is the mechanism of action of angiotensin-converting enzyme (ACE) inhibitors in heart failure management?
Inhibition of the renin-angiotensin-aldosterone system (RAAS)
ExplanationBlocks a hormone system that causes blood vessels to narrow.
#9
In heart failure with preserved ejection fraction (HFpEF), what is a characteristic finding on echocardiogram?
Left atrial enlargement
ExplanationEnlargement of the left atrium due to pressure overload.
#10
What is the main purpose of using aldosterone antagonists in heart failure management?
Reducing myocardial fibrosis and improving ventricular remodeling
ExplanationPrevents scarring of heart tissue and improves heart function.
#11
What is the primary mechanism of action of sacubitril/valsartan (Entresto) in heart failure treatment?
Inhibition of neprilysin
ExplanationCombines two drugs to improve heart function and symptoms.
