INTRODUCTION
The CMC Cardiac Medicine Certification assessment is designed to evaluate the
advanced knowledge and clinical expertise of nursing professionals caring for adult
patients with cardiac disease. This comprehensive exam covers a broad spectrum of
clinical scenarios, focusing on the pathophysiology, assessment, and management of
,acute and chronic cardiac conditions. The assessment utilizes a multiple-choice
format paired with high-stakes scenario-based questions to mirror the complexity of
the clinical environment. By emphasizing real-world application, critical thinking, and
rapid decision-making, this exam ensures that practitioners possess the specialized
skills necessary to optimize patient outcomes, adhere to regulatory standards, and
maintain the highest level of professional ethics in cardiac care.
1. A patient with a history of heart failure presents with increased dyspnea and
orthopnea. Physical assessment reveals bibasilar crackles and a S3 gallop.
Which hemodynamic finding is most likely present?
A. Decreased Systemic Vascular Resistance (SVR)
B. Increased Pulmonary Capillary Wedge Pressure (PCWP)
C. Increased Cardiac Index (CI)
D. Decreased Right Atrial Pressure (RAP)
🟢 Correct Answer: B
🔴 RATIONALE: PCWP reflects left atrial pressure and left ventricular end-diastolic
pressure. In left-sided heart failure, fluid backs up into the lungs, increasing PCWP
and causing pulmonary congestion.
, 2. A patient in the CCU develops sudden onset chest pain and a new holosystolic
murmur heard best at the apex, radiating to the axilla. The patient is becoming
increasingly hypotensive. What is the most likely complication?
A. Ventricular septal rupture
B. Acute pericarditis
C. Acute mitral regurgitation
D. Cardiac tamponade
🟢 Correct Answer: C
🔴 RATIONALE: Acute mitral regurgitation, often due to papillary muscle rupture
following an inferior MI, presents with a holosystolic murmur at the apex and rapid
hemodynamic deterioration.
3. Which of the following ECG changes is most characteristic of early
hyperkalemia?
A. Prominent U waves
B. ST-segment depression
C. Narrow, peaked T waves
D. Prolonged QT interval
, 🟢 Correct Answer: C
🔴 RATIONALE: Tall, peaked (tented) T waves are the earliest ECG sign of
hyperkalemia. As potassium levels rise further, the PR interval prolongs and the QRS
widens.
4. A patient is receiving Nitroprusside for a hypertensive crisis. The nurse notes
the patient is becoming confused and agitated, and the blood gas shows a
metabolic acidosis. What is the priority intervention?
A. Increase the infusion rate
B. Administer a bolus of Normal Saline
C. Stop the infusion and notify the provider
D. Administer intravenous Lorazepam
🟢 Correct Answer: C
🔴 RATIONALE: These are classic signs of thiocyanate/cyanide toxicity, a known risk
of prolonged or high-dose Nitroprusside administration. The infusion must be stopped
immediately.
5. When assessing a patient with a permanent pacemaker, the nurse notes a
pacing spike followed by a QRS complex, but the spike occurs earlier than the
