NR 667 CEA Exit Exam Practice Questions
200 Multiple Choice Questions with Answers and Rationales
Section 1: Cardiovascular System (Questions 1-30)
1. A 63-year-old male with a history of hypertension and diabetes presents with
exertional chest pressure that resolves with rest. The pain has been stable for the
past 6 months. Which diagnosis is most consistent with these findings?
A) Unstable angina
B) Stable angina
C) Myocardial infarction
D) Pericarditis
Answer: B) Stable angina
Rationale: Stable angina is characterized by predictable chest pain provoked by
physical exertion or emotional stress and relieved within minutes by rest or
nitroglycerin. Unlike unstable angina, it does not occur at rest or increase in
frequency. The stability of symptoms over 6 months supports this diagnosis .
,2. A 58-year-old female presents with acute shortness of breath, orthopnea, and
bilateral lower extremity edema. She has a history of myocardial infarction 3
years ago. Echocardiogram shows an ejection fraction of 30%. Which medication
class should be initiated as part of guideline-directed medical therapy?
A) Calcium channel blockers
B) Beta-blockers
C) Thiazolidinediones
D) Direct vasodilators
Answer: B) Beta-blockers
Rationale: Patients with heart failure with reduced ejection fraction (HFrEF, EF <
40%) should be treated with guideline-directed medical therapy including beta-
blockers (carvedilol, metoprolol succinate, or bisoprolol), ACE inhibitors or ARBs,
and loop diuretics for volume management. Beta-blockers reduce mortality and
hospitalizations in HFrEF .
3. A patient presents with new-onset atrial fibrillation with a ventricular rate of
110 bpm. The patient reports symptoms started 4 days ago. What is the priority
intervention before attempting cardioversion?
,A) Immediate electrical cardioversion
B) Rate control and anticoagulation
C) Administer amiodarone bolus
D) Schedule cardiac catheterization
Answer: B) Rate control and anticoagulation
Rationale: In atrial fibrillation of >48 hours or unknown duration, guidelines
recommend rate control and anticoagulation for at least 3 weeks before
cardioversion to reduce the risk of thromboembolic events. Transesophageal
echocardiogram may be an alternative to rule out left atrial thrombus before
cardioversion .
4. Which electrolytes are primarily involved in the function of the atria?
A) Sodium and potassium
B) Potassium and calcium
C) Sodium and calcium
D) Magnesium and potassium
, Answer: B) Potassium and calcium
Rationale: The atria (top chambers of the heart) work on potassium (K+) and
calcium (Ca). This is why medications that work on K+ or Ca channels, such as
Cardizem (calcium channel blocker) or Amiodarone (potassium channel blocker),
are used to treat atrial conditions .
5. Which electrolytes are primarily involved in the function of the ventricles?
A) Potassium and calcium
B) Sodium and calcium
C) Sodium and potassium
D) Magnesium and potassium
Answer: C) Sodium and potassium
Rationale: The ventricles (bottom chambers of the heart) work on sodium (Na)
and potassium (K+). This explains why medications affecting Na or K channels are
used for ventricular conditions .
