Correct Answer: C

Rationale: Severe pain around the eyes that radiates over the face is a characteristic symptom of acute angle-closure glaucoma. This intense pain is typically accompanied by other symptoms such as blurred vision, halos around lights, redness in the eye, and sometimes nausea and vomiting. The acute rise in intraocular pressure leads to these symptoms, indicating a medical emergency that requires immediate attention to prevent vision loss.

Correct Answer: B

Rationale: Spironolactone is a potassium-sparing diuretic, meaning it can cause potassium retention, leading to elevated potassium levels. A potassium level of 5.2 mEq/L is above the normal range (3.5-5.0 mEq/L) and indicates hyperkalemia, which can be a serious condition. Therefore, this finding should be promptly reported to the healthcare provider for further evaluation and management to prevent potential complications.

Correct Answer: B

Rationale: The correct answer is to monitor the client's potassium levels. Hypokalemia can increase the risk of Digoxin toxicity. Potassium levels should be closely monitored to prevent adverse effects.

Correct Answer: D
