SECTION 1: CARDIOVASCULAR DISORDERS (Questions 1–30)
1. A 62-year-old male with a 15-year history of type 2 diabetes mellitus presents for routine
evaluation. His blood pressure is 148/92 mmHg, BMI is 31 kg/m², and laboratory studies
reveal LDL-C of 145 mg/dL, HDL-C of 38 mg/dL, and triglycerides of 210 mg/dL. According to
current cardiovascular risk reduction guidelines, what is the most appropriate initial
management strategy for this patient?
A. Initiate lifestyle modifications only and re-evaluate in 6 months
B. Initiate statin therapy and lifestyle modifications with a target LDL-C reduction of ≥50%
C. Initiate antihypertensive therapy with an ACE inhibitor and re-check lipids in 3 months
D. Refer to cardiology for coronary angiography
Rationale: This patient has diabetes mellitus with elevated LDL-C and meets criteria for high-risk
primary prevention. Current guidelines recommend high-intensity statin therapy for patients
with diabetes and LDL-C ≥100 mg/dL, targeting a ≥50% reduction in LDL-C. Lifestyle
modifications alone would be insufficient given the significant cardiovascular risk profile.
2. A 55-year-old female presents with complaints of progressive shortness of breath on
exertion, fatigue, and ankle swelling over the past 2 months. She has a history of
hypertension treated with lisinopril. Physical examination reveals jugular venous distention,
S3 gallop, and 2+ pitting edema to the knees. What is the most appropriate next step in the
evaluation of this patient?

,Page 2 of 71
A. Order a chest X-ray and complete blood count
B. Order a transthoracic echocardiogram
C. Start furosemide 40 mg daily and schedule follow-up in 2 weeks
D. Obtain serum BNP level and comprehensive metabolic panel
Rationale: This patient presents with classic signs and symptoms of heart failure (exertional
dyspnea, fatigue, peripheral edema, JVD, S3 gallop). An echocardiogram is essential to assess
left ventricular ejection fraction and guide management.
3. A 45-year-old male with no known cardiac history presents with palpitations and a heart
rate of 150 bpm. ECG shows a narrow-complex tachycardia with regular rhythm. What is the
most appropriate initial management?
A. Administer adenosine 6 mg IV push
B. Administer amiodarone 150 mg IV
C. Perform synchronized cardioversion
D. Administer diltiazem 20 mg IV
Rationale: Adenosine is the first-line treatment for stable narrow-complex regular tachycardia
(suspected SVT) after vagal maneuvers fail.
4. A 68-year-old female with atrial fibrillation on warfarin has an INR of 5.8. She is not
bleeding. What is the most appropriate management?
A. Administer vitamin K 10 mg IV
B. Hold warfarin and administer vitamin K 2.5 mg PO
C. Transfuse fresh frozen plasma
D. Continue warfarin and recheck INR in 2 days
Rationale: For INR 5–9 without bleeding, the recommended management is to hold warfarin
and administer low-dose oral vitamin K (2.5 mg) unless rapid reversal is needed.
5. A 72-year-old male with heart failure (EF 35%) has a potassium level of 5.6 mEq/L while
taking lisinopril and spironolactone. What is the most appropriate management?
A. Continue both medications and recheck potassium in 1 week
2|Page
,Page 3 of 71
B. Discontinue spironolactone and recheck potassium
C. Discontinue lisinopril and continue spironolactone
D. Add furosemide to promote potassium excretion
Rationale: Spironolactone is a potassium-sparing diuretic that can cause hyperkalemia,
especially when combined with ACE inhibitors. In this case, spironolactone should be
discontinued first.
6. A 58-year-old female presents with new-onset hypertension (BP 158/96 mmHg). She has no
comorbidities. According to JNC 8 guidelines, which medication class is first-line?
A. ACE inhibitor
B. Beta-blocker
C. Thiazide diuretic or calcium channel blocker
D. Alpha-blocker
Rationale: For Black patients without comorbidities, JNC 8 recommends thiazide diuretics or
calcium channel blockers as first-line therapy.
7. A 65-year-old male with stable angina is prescribed metoprolol. Which assessment finding
would require the nurse to hold the medication?
A. Heart rate 88 bpm
B. Blood pressure 110/70 mmHg
C. Heart rate 52 bpm
D. Respiratory rate 18 breaths/min
Rationale: Beta-blockers should be held if heart rate is below 60 bpm or systolic blood pressure
is below 90 mmHg.
8. A 70-year-old female with heart failure is prescribed furosemide. Which laboratory value
requires immediate intervention?
A. Potassium 3.8 mEq/L
B. Sodium 138 mEq/L
3|Page
, Page 4 of 71
C. Potassium 3.1 mEq/L
D. BUN 18 mg/dL
Rationale: Loop diuretics can cause hypokalemia. A potassium level below 3.5 mEq/L requires
intervention.
9. A 55-year-old male with a mechanical mitral valve on warfarin has a target INR of:
A. 1.5–2.0
B. 2.0–3.0
C. 2.5–3.5
D. 3.0–4.0
Rationale: The target INR for mechanical mitral valves is 2.5–3.5.
10. A 48-year-old male presents with chest pain relieved by rest. ECG shows ST depression.
What is the most likely diagnosis?
A. STEMI
B. Unstable angina/NSTEMI
C. Stable angina
D. Pericarditis
Rationale: ST depression with chest pain at rest suggests unstable angina/NSTEMI.
11. A 62-year-old female with diabetes has a blood pressure of 138/82 mmHg. What is the
target blood pressure for this patient?
A. <140/90 mmHg
B. <130/80 mmHg
C. <120/70 mmHg
D. <150/90 mmHg
Rationale: For patients with diabetes, the target blood pressure is <130/80 mmHg.
12. A 75-year-old male with heart failure is prescribed carvedilol. Which instruction should be
included?
