COMPREHENSIVE TEST FORMS A & B 2026
QUESTIONS WITH ANSWERS GRADED A+
◉ A nurse is caring for a client who has a major burn injury and is
experiencing third spacing. Which of the following fluid or
electrolyte imbalances should the nurse expect?
A. Hypokalemia
B. Hypernatremia
C. Elevated Hct
D. Decreased Hgb. Answer: C. Elevated Hct
The nurse should expect a client who is experiencing third spacing
resulting from a major burn to have an elevated hematocrit level as
blood volume is reduced by vascular dehydration.
Incorrect Answers:
A. The nurse should expect the client to have hyperkalemia as a
result of potassium being leaked from cellular injury.
B. The nurse should expect the client to have hyponatremia once
sodium leaks into the interstitial space, causing decreased levels in
the blood.
,D. The nurse should expect the client to have an increased
hemoglobin level as blood volume is reduced by vascular
dehydration.
◉ A nurse is examining the ECG of a client who has frequent
premature ventricular contractions (PVCs). Which of the following
QRS changes should the nurse expect to see on the client's ECG?
A. Narrower than usual QRS complexes
B. Much greater amplitude than the usual QRS complexes
C. Same polarity as the usual QRS complexes
D. Immediate resumption of the usual rhythm. Answer: B. Much
greater amplitude than the usual QRS complexes
The QRS complexes unusually have greater amplitude in height and
depth in clients with PVCs.
◉ A nurse is caring for a client who is experiencing autonomic
dysreflexia due to a C5 spinal cord injury. After checking the client's
vital signs, which of the following actions should the nurse perform
next?
A. Administer nifedipine
B. Place the client in a high-Fowler's position
, C. Check for urinary retention
D. Check for a fecal impaction. Answer: B. Place the client in a high-
Fowler's position
According to evidence-based practice, the nurse should first place
the client in a high-Fowler's position to decrease the client's blood
pressure and reduce the risk of end-organ damage from the sudden
rise in blood pressure.
◉ A nurse is monitoring a client for reperfusion following
thrombolytic therapy to treat acute myocardial infarction (MI).
Which of the following indicators should the nurse identify to
confirm reperfusion?
A. Ventricular dysrhythmias
B. Appearance of Q waves
C. Elevated ST segments
D. Recurrence of chest pain. Answer: A. Ventricular dysrhythmias
The appearance of ventricular dysrhythmias following thrombolytic
therapy is a sign of reperfusion of the coronary artery.
◉ A nurse is teaching a newly licensed nurse about caring for a
client who is scheduled for an esophagogastric balloon tamponade
