University Comprehensive Nursing Practice Questions with
Answers and Detailed Rationales With 50+ QA and
Rationales
Question 1
A nurse is reviewing laboratory results for an individual admitted with
dehydration. Which laboratory value is most consistent with dehydration?
A. Hematocrit of 54%
B. Sodium level of 134 mEq/L
C. Potassium level of 3.5 mEq/L
D. Blood glucose of 92 mg/dL
Correct Answer✅:
A. Hematocrit of 54%
Rationale:
Dehydration reduces plasma volume, resulting in hemoconcentration and an
elevated hematocrit. This finding is commonly accompanied by increased blood
urea nitrogen (BUN) and serum osmolality.
,Question 2
A nurse is caring for an individual receiving intravenous furosemide. Which
electrolyte imbalance requires close monitoring?
A. Hypercalcemia
B. Hypernatremia
C. Hypokalemia
D. Hypermagnesemia
Correct Answer✅:
C. Hypokalemia
Rationale:
Loop diuretics such as furosemide increase urinary potassium excretion, placing
individuals at risk for hypokalemia. Low potassium can contribute to muscle
weakness and potentially life-threatening cardiac dysrhythmias.
Question 3
Which assessment finding should be reported immediately following
administration of an opioid analgesic?
A. Respiratory rate of 8 breaths/minute
B. Mild nausea after eating
C. Pain score decreasing from 8 to 4

A. Respiratory rate of 8 breaths/minute
, Rationale:
Respiratory depression is the most serious adverse effect associated with opioid
medications. Immediate assessment and intervention are required to prevent
respiratory failure.
