Correct Answer is D
Explanation
A. Bradycardia: Bradycardia is not a common side effect of diphenhydramine. This medication primarily causes sedation and anticholinergic effects.
B. Hypertension: Hypertension is not commonly associated with diphenhydramine, which tends to have more sedative and anticholinergic side effects.
C. Bleeding: Bleeding is not a known side effect of diphenhydramine. It does not affect clotting mechanisms or platelet function.
D. Sedation: Sedation is a common side effect of diphenhydramine, which is an antihistamine with sedative properties. Clients should be advised about possible drowsiness and to avoid activities that require alertness, like driving, while taking it.
Correct Answer is D
Explanation
A. Digoxin: Digoxin requires caution with elevated potassium levels, as hyperkalemia can increase the risk of digoxin toxicity. A potassium level of 5.3 mEq/L is borderline high, so it should be used cautiously.
B. Lisinopril: Lisinopril, an ACE inhibitor, can also increase potassium levels. It may not be the best choice for this client due to the elevated potassium.
C. Potassium iodide: Potassium iodide would further increase the client's potassium level and is contraindicated.
D. Furosemide: Furosemide is a loop diuretic that can help to lower serum potassium levels by promoting potassium excretion. Therefore, it is appropriate for this client with an elevated potassium level.
