A nurse is caring for a client who is receiving an IV infusion of potassium chloride. Which of the following complications should the nurse recognize as an indication to discontinue the infusion?
Hypomagnesemia
Neutropenia
Coughing
Hyperkalemia
The Correct Answer is D
A. Hypomagnesemia: Low magnesium levels are not an indication to stop a potassium infusion, although magnesium and potassium levels are related. Correction of magnesium may be necessary, but hypomagnesemia alone does not warrant discontinuation.
B. Neutropenia: A low white blood cell count is not directly related to potassium administration and does not require stopping the infusion.
C. Coughing: Respiratory symptoms like coughing are not a recognized complication of potassium chloride infusion and do not indicate the need to discontinue therapy.
D. Hyperkalemia: Elevated potassium levels can be life-threatening due to the risk of cardiac arrhythmias. If laboratory results or clinical signs indicate hyperkalemia, the potassium infusion should be immediately discontinued and appropriate interventions initiated.

Explanation
Rationales for Correct Choices
- Not take the antacid within 30 min of the sucralfate: Antacids can interfere with the absorption and adherence of sucralfate to the gastric mucosa. Spacing administration by at least 30 minutes ensures optimal therapeutic action of both medications.
- Shake the suspension thoroughly before administration: Sucralfate is a suspension, meaning its medication particles are dispersed in a liquid. To ensure the client receives the correct, full dose and therapeutic effect, the medication must be shaken well immediately before measuring and administering.
Rationale for Incorrect Choices:
- Discontinue the sucralfate as soon as ulcer manifestations subside: Stopping sucralfate too early can prevent complete healing of the ulcer. Full courses should be completed as prescribed.
- Take the sucralfate with meals: Sucralfate should be taken on an empty stomach (at least 1hour before meals and at bedtime) to allow it to form the protective barrier on the ulcer before food and acid production increase.
Correct Answer is B
Explanation
A. Take the medication in the morning: Simvastatin is more effective when taken in the evening because cholesterol synthesis is higher at night. Taking it in the morning may reduce its lipid-lowering effect.
B. Report muscle tenderness: Muscle pain, tenderness, or weakness can indicate myopathy or rhabdomyolysis, serious adverse effects of statins. Clients should report these symptoms promptly for evaluation and possible medication adjustment.
C. This medication can cause kidney damage: Simvastatin primarily affects the liver and muscles. While rhabdomyolysis can indirectly impact kidney function, kidney damage is not a common direct effect of the medication.
D. Avoid drinking grapefruit juice for 3 hr after taking this medication: Grapefruit juice can inhibit metabolism of simvastatin, increasing the risk of toxicity. Avoiding grapefruit entirely, rather than timing it around the dose, is the recommended precaution.
