1. A nurse is preparing to administer furosemide (Lasix) to a client. Which
laboratory value is the priority for the nurse to check before administration?
A. Serum Sodium
B. Serum Glucose
C. Serum Calcium
D. Serum Potassium
Answer: D
Rationale: Furosemide is a loop diuretic that commonly causes potassium depletion;
therefore, the nurse must monitor for hypokalemia.
2. When administering digoxin (Lanoxin), at what heart rate should the nurse
withhold the medication for an adult client?
A. Below 100 bpm
B. Below 60 bpm
C. Below 80 bpm
D. Above 110 bpm
Answer: B
Rationale: Digoxin should be withheld if the apical pulse is less than 60 beats per minute
in an adult to avoid bradycardia.
,3. Which of the following is a classic sign of hypoglycemia?
A. Diaphoresis and shakiness
B. Fruity breath odor
C. Extreme thirst
D. Abdominal pain
Answer: A
Rationale: Hypoglycemia manifests as sweating (diaphoresis), tremors, shakiness, and
confusion due to low blood glucose levels.

held for 48 hours after the procedure?
A. Furosemide

A. Crackles in the lungs
B. Dyspnea on exertion
C. Peripheral edema
D. Frothy pink sputum
