1. A nurse is assessing a client with left-sided heart failure. Which of the following findings
should the nurse expect?
A. Jugular venous distention
B. Dependent edema
C. Crackles in the lung bases
D. Ascites
Answer: C
Rationale: Left-sided heart failure results in pulmonary congestion due to the heart’s
inability to pump blood effectively into the systemic circulation. This fluid backup leads to
crackles, dyspnea, and orthopnea. Right-sided heart failure would more typically present
with systemic signs such as JVD and peripheral edema.
2. Which electrolyte imbalance is a patient most at risk for when taking a non-potassium-
sparing diuretic like Furosemide?
A. Hyperkalemia
B. Hypokalemia
,C. Hypernatremia
D. Hypocalcemia
Answer: B
Rationale: Loop diuretics like Furosemide increase the excretion of water, sodium, and
potassium from the kidneys. The nurse must monitor for hypokalemia, which can cause
cardiac arrhythmias. Patients are often encouraged to increase dietary potassium intake or
take supplements while on this medication.
3. A client is admitted with a suspected Myocardial Infarction (MI). Which cardiac enzyme is
most sensitive and specific for diagnosing an MI?
A. Myoglobin
B. CK-MB
C. LDH
D. Troponin I
Answer: D
Rationale: Troponin I is highly specific to cardiac muscle and is the preferred marker for
diagnosing myocardial injury. It begins to rise within a few hours of an MI and remains
elevated for up to two weeks. CK-MB is also used but is less specific than Troponin.
, 4. When caring for a client with a history of Chronic Obstructive Pulmonary Disease (COPD),
which oxygen delivery method is typically preferred for precise titration?
A. Simple face mask
B. Venturi mask
C. Non-rebreather mask
D. Partial rebreather mask
Answer: B
Rationale: The Venturi mask is the most accurate method for delivering a precise
concentration of oxygen. This is critical for COPD patients who may rely on a hypoxic drive
to breathe. Providing too much oxygen can suppress their respiratory drive.
5. A nurse is reviewing the arterial blood gas (ABG) results for a patient: pH 7.30, PaCO2 52,
HCO3 24. How should the nurse interpret these results?
A. Metabolic Acidosis
B. Respiratory Acidosis
C. Respiratory Alkalosis
D. Metabolic Alkalosis
Answer: B
Rationale: The pH is below 7.35, indicating acidosis, and the PaCO2 is above 45, indicating
a respiratory cause. The HCO3 is within the normal range, suggesting no compensation has
