1. A nurse is assessing a patient with left-sided heart failure. Which clinical manifestation
should the nurse expect to find?
A. Jugular venous distention
B. Peripheral edema
,C. Crackles in the lungs
D. Abdominal distention
Correct Answer: C
Expert Explanation: Left-sided heart failure leads to pulmonary congestion, causing fluid
to back up into the lungs, which results in crackles, dyspnea, and cough.
2. Which laboratory value is most specific for diagnosing a myocardial infarction (MI)?
A. Creatine kinase (CK-MB)
B. Myoglobin
C. Troponin I
D. C-reactive protein
Correct Answer: C
Expert Explanation: Troponin I is a highly specific cardiac marker for myocardial injury
and remains elevated longer than CK-MB, making it the gold standard for MI diagnosis.
3. A patient with COPD is receiving oxygen therapy via a nasal cannula at 2 L/min. Which
finding indicates the therapy is effective?
A. SpO2 level of 90%
B. PaCO2 of 55 mmHg
C. Respiratory rate of 28 breaths/min
, D. Bicarbonate level of 24 mEq/L
Correct Answer: A
Expert Explanation: For patients with COPD, a target SpO2 of 88% to 92% is often
acceptable to maintain the hypoxic drive while providing adequate oxygenation.
4. A nurse is caring for a patient with a potassium level of 2.8 mEq/L. Which ECG change is
most characteristic of this electrolyte imbalance?
A. Peaked T waves
B. Widened QRS complex
C. Presence of U waves
D. Shortened QT interval
Correct Answer: C
Expert Explanation: Hypokalemia typically presents with flat or inverted T waves and the
appearance of U waves on an ECG.
5. A patient with Type 1 Diabetes is found unconscious and clammy. What is the priority
nursing action?
A. Administer 15g of simple carbohydrates orally
B. Check the patient’s blood glucose level
C. Administer glucagon intramuscularly
D. Call the healthcare provider immediately
