1. A nurse is caring for a client admitted with acute myocardial
infarction (MI). Which assessment finding requires immediate
intervention?
A. Heart rate of 92 beats/min
B. Blood pressure of 128/76 mmHg
C. Chest pain rated 9/10 despite nitroglycerin administration
D. Respiratory rate of 18 breaths/min
Rationale: Persistent severe chest pain after nitroglycerin
suggests ongoing myocardial ischemia and requires immediate
evaluation to prevent further myocardial damage.
Correct Answer: C
2. Which laboratory value is the most specific indicator of
myocardial injury?
A. Myoglobin
B. Troponin I
C. Creatine kinase (CK)
D. Lactate dehydrogenase (LDH)
,Rationale: Troponin I is highly specific and sensitive for
myocardial cell injury and remains elevated for several days
after an MI.
Correct Answer: B
3. A client with heart failure reports increasing shortness of
breath when lying flat. Which term best describes this
symptom?
A. Dyspnea
B. Orthopnea
C. Tachypnea
D. Hyperventilation
Rationale: Orthopnea is difficulty breathing while lying flat and
is a common manifestation of left-sided heart failure.
Correct Answer: B
4. Which assessment finding is most consistent with left-sided
heart failure?
A. Peripheral edema
B. Jugular vein distention
C. Pulmonary crackles
D. Ascites
,Rationale: Left-sided heart failure results in pulmonary
congestion, leading to crackles, dyspnea, and decreased
oxygenation.
Correct Answer: C
5. A client with chronic obstructive pulmonary disease (COPD)
is receiving oxygen therapy. Which oxygen saturation should
the nurse generally aim to maintain?
A. 100%
B. 98–100%
C. 88–92%
D. 75–80%
Rationale: Many clients with COPD require oxygen titration to
maintain saturation between 88% and 92% to reduce the risk of
suppressing respiratory drive while ensuring adequate
oxygenation.
Correct Answer: C
6. Which intervention should the nurse implement first for a
client experiencing an acute asthma attack?
A. Encourage coughing exercises
B. Administer a prescribed short-acting bronchodilator
C. Restrict oral fluids
D. Obtain a sputum culture
, Rationale: Rapid bronchodilation is the priority intervention to
relieve airway obstruction during an acute asthma attack.
Correct Answer: B
7. Which finding indicates effective treatment for pneumonia?
A. Increasing white blood cell count
B. Improved oxygen saturation and decreased crackles
C. Persistent fever
D. Increased productive cough with blood
Rationale: Improved oxygenation and clearer lung sounds
indicate that the infection and inflammation are resolving.
Correct Answer: B
8. A nurse is assessing a client with chronic kidney disease.
Which laboratory value is expected?
A. Decreased serum creatinine
B. Elevated blood urea nitrogen (BUN)
C. Low potassium level
D. Increased hemoglobin
Rationale: Reduced kidney function causes waste products
such as BUN to accumulate in the bloodstream.
Correct Answer: B
