Section 1: Cardiovascular System
1. A 68-year-old male with a history of hypertension and diabetes presents with
exertional dyspnea and fatigue. His BP is 155/90, HR 88. An S3 gallop is heard on
auscultation. Which of the following medications is most likely to reduce his
mortality?
A. Amlodipine
B. Furosemide
C. Carvedilol
D. Digoxin
Correct Answer: C. Carvedilol
Rationale: The patient presents with signs and symptoms of heart failure
with reduced ejection fraction (HFrEF), indicated by an S3 gallop and exertional
symptoms. Beta-blockers, specifically carvedilol, metoprolol succinate, and
bisoprolol, are a cornerstone of therapy for HFrEF and have been shown to
reduce mortality. Amlodipine and furosemide manage symptoms but do not have
a proven mortality benefit in HFrEF. Digoxin reduces hospitalizations but has a
neutral effect on mortality.
2. A 55-year-old female is started on an ACE inhibitor for hypertension. One
week later, she returns complaining of a persistent, dry, hacking cough. What is
the most appropriate next step in management?
A. Add an inhaled corticosteroid.
B. Discontinue the ACE inhibitor and switch to an ARB.
C. Reduce the dose of the ACE inhibitor.
D. Reassure the patient that the cough will resolve.
Correct Answer: B. Discontinue the ACE inhibitor and switch to an ARB.
Rationale: A dry, persistent cough is a common and class-specific side
,effect of ACE inhibitors, caused by the accumulation of bradykinin. It does not
resolve with continued use or dose reduction. The most appropriate management
is to discontinue the ACE inhibitor and switch to an Angiotensin II Receptor
Blocker (ARB), which does not affect bradykinin levels and is not associated with
this side effect.
3. Which of the following ECG findings is most characteristic of hyperkalemia?
A. Prolonged QT interval
B. Prominent U waves
C. Tall, peaked T waves
D. ST-segment depression
Correct Answer: C. Tall, peaked T waves
Rationale: Hyperkalemia is a common electrolyte abnormality that affects
cardiac conduction. The earliest and most classic ECG change is the appearance of
tall, narrow, peaked T waves. As potassium levels rise further, this can progress to
a widened QRS complex, a flattened P wave, and eventually a sine wave pattern,
which can lead to ventricular fibrillation or asystole. Prominent U waves are
associated with hypokalemia.
4. A 72-year-old male with atrial fibrillation is on warfarin. His INR is 6.5, but he
has no active bleeding. What is the most appropriate management?
A. Administer Vitamin K 10 mg IV.
B. Hold warfarin and administer Fresh Frozen Plasma (FFP).
C. Hold warfarin and administer oral Vitamin K.
D. Continue warfarin at the same dose and recheck INR in 3 days.
Correct Answer: C. Hold warfarin and administer oral Vitamin K.
Rationale: For an INR > 5.0 (some guidelines say > 4.5) without active
bleeding, the recommended management is to hold the next dose of warfarin and
administer a low dose of oral Vitamin K (1-2.5 mg). IV Vitamin K is reserved for
life-threatening bleeding due to the risk of anaphylaxis. FFP is also reserved for
serious bleeding. Simply holding the drug is insufficient for an INR of 6.5.
5. A patient presents with crushing substernal chest pain. An ECG shows ST-
segment elevation in leads II, III, and aVF. Which coronary artery is most likely
occluded?
,A. Left Anterior Descending (LAD)
B. Left Circumflex (LCx)
C. Right Coronary Artery (RCA)
D. Left Main Coronary Artery
Correct Answer: C. Right Coronary Artery (RCA)
Rationale: ST-segment elevation in leads II, III, and aVF indicates an
inferior wall myocardial infarction. The inferior wall of the heart is most
commonly supplied by the Right Coronary Artery (RCA) in a right-dominant
circulation. An LAD occlusion would typically show changes in V1-V4 (anterior). An
LCx occlusion would typically show changes in I, aVL, V5, V6 (lateral).
6. Which of the following is a classic side effect of amiodarone that requires
routine monitoring?
A. Renal failure
B. Hyperthyroidism
C. Hyperkalemia
D. Hypertension
Correct Answer: B. Hyperthyroidism
Rationale: Amiodarone is a highly effective antiarrhythmic but has
significant toxicity. Because of its high iodine content, it can cause both
hyperthyroidism and hypothyroidism. Routine monitoring of thyroid function
tests (TSH, Free T4) is essential. It can also cause pulmonary fibrosis, corneal
microdeposits, hepatotoxicity, and a blue-gray skin discoloration.
7. A 65-year-old male with a history of heart failure presents with weight gain,
increased abdominal girth, and 3+ pitting edema in his lower extremities. Which
class of medication is most appropriate for acute symptom relief?
A. Loop diuretics
B. Beta-blockers
C. ACE inhibitors
D. Statins
Correct Answer: A. Loop diuretics
Rationale: The patient is exhibiting classic signs of acute decompensated
heart failure with fluid overload. Loop diuretics, such as furosemide, are the first-
, line agents for rapid symptomatic relief of congestion and edema. They work by
inhibiting sodium and chloride reabsorption in the ascending loop of Henle,
leading to potent diuresis. Beta-blockers and ACE inhibitors are for long-term
mortality benefit, not acute diuresis.
8. A 40-year-old female is diagnosed with mitral valve prolapse. She is most
likely to present with which of the following symptoms?
A. Exertional angina and syncope
B. Asymptomatic or atypical chest pain and palpitations
C. Severe dyspnea on exertion and orthopnea
D. Peripheral edema and jugular venous distension
Correct Answer: B. Asymptomatic or atypical chest pain and palpitations
Rationale: Mitral valve prolapse (MVP) is often asymptomatic. When
symptoms do occur, they are typically atypical, such as non-exertional chest pain,
palpitations, fatigue, or dyspnea. Severe symptoms like syncope, exertional
angina, or signs of heart failure are more characteristic of severe valve disease like
aortic stenosis or mitral regurgitation.
9. Which of the following lipid-lowering agents works by binding to bile acids in
the intestine?
A. Atorvastatin
B. Ezetimibe
C. Cholestyramine
D. Fenofibrate
Correct Answer: C. Cholestyramine
Rationale: Cholestyramine is a bile acid sequestrant. It is a non-absorbed
resin that binds to bile acids in the intestine, preventing their reabsorption. This
forces the liver to use cholesterol to synthesize new bile acids, which up-regulates
LDL receptors and lowers LDL cholesterol. Atorvastatin is a statin (HMG-CoA
reductase inhibitor), Ezetimibe blocks cholesterol absorption, and Fenofibrate is a
fibrate.
10. A 78-year-old male on furosemide for heart failure presents with generalized
weakness and a heart rate of 110 with an irregular rhythm. His ECG shows
prominent U waves. What is the most likely electrolyte abnormality?
