Correct Answer: B

Rationale: Spironolactone is a potassium-sparing diuretic commonly used in patients with heart failure. The nurse should monitor for signs of hyperkalemia, which is a potential side effect of spironolactone therapy. Hyperkalemia can lead to serious cardiac arrhythmias, so close monitoring of potassium levels is essential to prevent complications.

Correct Answer: B

Rationale: Increasing sharp pain related to compartment syndrome necessitates immediate intervention as it may lead to permanent damage to muscles and nerves. Compartment syndrome is a serious condition that requires urgent medical attention to prevent further complications such as tissue necrosis and nerve injury.

Correct Answer: C

Rationale: Numbness and tingling around the mouth can indicate hypocalcemia, a potential complication after thyroidectomy. Hypocalcemia can occur due to inadvertent injury or removal of the parathyroid glands during the thyroidectomy, leading to decreased calcium levels. As a result, the client may experience symptoms such as numbness, tingling, muscle cramps, or spasms. Prompt intervention is necessary to prevent severe complications like tetany or seizures. Therefore, the healthcare provider should address numbness and tingling around the mouth immediately to prevent further deterioration of calcium levels and potential serious outcomes.

Correct Answer: D

Rationale: The nurse's priority action in this situation is to notify the healthcare provider immediately. These symptoms, including severe pain, swelling, warmth, and redness in the leg, are indicative of deep vein thrombosis (DVT), a potentially serious condition. Prompt notification of the healthcare provider is crucial to initiate appropriate diagnostic tests and interventions to prevent complications associated with DVT.
