MDC III FINAL EXAM & STUDY GUIDE - 200 PRACTICE QUESTIONS

CARDIAC DISORDERS (Questions 1-40)

1. A patient with crackles, shortness of breath, and lower extremity edema likely has which
condition?

• A) Right-sided heart failure

• B) Left-sided heart failure

• C) Bradycardia

• D) Increased cardiac output

Correct Answer: B) Left-sided heart failure

Explanation: Left-sided heart failure leads to pulmonary congestion, resulting in crackles,
dyspnea, and eventually peripheral edema as the condition progresses .



2. What type of heart sound would you expect to hear in a patient with mitral regurgitation?

• A) High-pitched holosystolic murmur

• B) Blowing, decrescendo diastolic murmur

• C) S3 gallop only

• D) Systolic ejection murmur

Correct Answer: A) High-pitched holosystolic murmur

Explanation: Mitral regurgitation produces a high-pitched holosystolic murmur best heard at the
apex with radiation to the axilla .



3. A patient with untreated mitral regurgitation is at risk for developing:

, • A) Right-sided heart failure

• B) Left-sided heart failure

• C) Cardiac tamponade

• D) Pericarditis

Correct Answer: B) Left-sided heart failure

Explanation: Chronic mitral regurgitation increases left ventricular volume and pressure,
eventually leading to left-sided heart failure if left untreated .



4. What assessment finding would be consistent with left-sided heart failure? (Select all that
apply)

• A) Shortness of breath

• B) Chest X-ray showing pulmonary congestion

• C) Elevated BNP

• D) Peripheral edema only

Correct Answer: A, B, C

Explanation: Left-sided heart failure presents with respiratory symptoms (SOB), pulmonary
congestion on imaging, and elevated BNP. Peripheral edema is more characteristic of right-sided
failure .



5. The most accurate way to assess fluid gain in a heart failure patient is:

• A) Measuring intake and output

• B) Daily weights on the same scale before breakfast

• C) Assessing peripheral edema

• D) Monitoring urine output

Correct Answer: B) Daily weights on the same scale before breakfast

Explanation: Daily weights are the most reliable indicator of fluid status in heart failure patients.
A weight gain of 2-3 lbs in 24 hours may indicate fluid retention .

,6. Which medication class is best for treating heart failure? (Select all that apply)

• A) ACE inhibitors

• B) Diuretics

• C) Beta blockers

• D) Nitrates

Correct Answer: A, B, C, D

Explanation: Heart failure treatment often includes a combination of ACE inhibitors, diuretics for
fluid management, beta blockers to reduce cardiac workload, and nitrates for vasodilation .



7. What is the best diagnostic tool for diagnosing heart failure?

• A) Chest X-ray

• B) Echocardiogram

• C) BNP level

• D) ECG

Correct Answer: B) Echocardiogram

Explanation: Echocardiogram provides information about ejection fraction, chamber size,
valvular function, and overall cardiac function, making it the gold standard for diagnosing heart
failure .



8. What is the surgical treatment of choice for end-stage heart failure?

• A) Ventricular assist devices (VADs)

• B) Cardiac resynchronization therapy

• C) Percutaneous angiogram

• D) Genetic counseling

Correct Answer: A) Ventricular assist devices (VADs)

, Explanation: VADs are mechanical pumps implanted to work with the patient's own heart,
dramatically improving outcomes in end-stage heart failure .



9. A patient with atrial fibrillation is at risk for:

• A) Hemorrhage

• B) Embolisms

• C) Bradycardia

• D) Hypotension

Correct Answer: B) Embolisms

Explanation: Atrial fibrillation causes blood to pool in the atria, increasing the risk of clot
formation and subsequent embolization .



10. A patient in atrial fibrillation with a heart rate of 180 bpm may present with: (Select all
that apply)

• A) Hypotension

• B) Dizziness

• C) Worsening heart failure

• D) Hypertension

Correct Answer: A, B, C

Explanation: Rapid ventricular response in afib reduces cardiac output, leading to hypotension,
dizziness, and can precipitate heart failure .



11. What rhythm is characterized by chaotic, disorganized electrical activity with no
identifiable P waves?

• A) Atrial fibrillation

• B) Ventricular tachycardia

• C) Atrial flutter
