,NR 293 Pharmacology Nursing: Nutrition and Renal Fluid/Electrolytes Exam 2026/2027
UPDATE
1. A patient is prescribed Furosemide for heart failure. Which mechanism of action correctly
describes this medication?
A. Inhibition of sodium and chloride reabsorption in the distal convoluted tubule
B. Antagonism of aldosterone receptors in the collecting duct
C. Inhibition of the Na-K-2Cl symporter in the thick ascending limb of the loop of Henle
D. Inhibition of carbonic acid conversion in the proximal tubule
Answer: C
Rationale: Loop diuretics like Furosemide work specifically in the thick ascending limb of
the loop of Henle by blocking the Na-K-2Cl symporter, leading to significant diuresis.
2. Which assessment finding is most critical for a nurse to monitor in a patient receiving
intravenous potassium chloride 10 mEq/hr?
A. Increased bowel sounds
B. Cardiac rhythm on telemetry
C. Urine output of 40 mL/hr
D. Blood pressure of 110/70 mmHg
, Answer: B
Rationale: Potassium imbalances directly affect cardiac conduction; continuous ECG
monitoring is essential to detect arrhythmias or peaked T waves indicative of
hyperkalemia.
3. A patient on Spironolactone is at highest risk for which electrolyte imbalance?
A. Hypokalemia
B. Hypernatremia
C. Hypocalcemia
D. Hyperkalemia
Answer: D
Rationale: Spironolactone is a potassium-sparing diuretic that antagonizes aldosterone,
causing the kidneys to retain potassium while excreting sodium and water.
4. Total Parenteral Nutrition (TPN) is being discontinued. Why must the nurse taper the
infusion rate rather than stopping it abruptly?
A. To prevent fluid volume overload
B. To prevent air embolism
C. To avoid sudden electrolyte shifts
D. To prevent rebound hypoglycemia
