Explanation
A history of gastric ulcers is a contraindication to the use of aspirin. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that can irritate the stomach lining and increase the risk of gastrointestinal bleeding and ulcers. Therefore, in a client with a history of gastric ulcers, aspirin should be avoided to prevent exacerbation of the condition and potential complications.

Correct Answer is D

Furosemide is a loop diuretic that blocks water reabsorption in the loop of Henle promoting diuresis. It also causes potassium loss in urine leading to hypokalemia. Checking potassium levels before administration of furosemide prevents worsening already existing hypokalemia.
Hypokalemia causes complications like cardiac dysrhythmias, muscle weakness, and fatigue. The nurse should monitor the client for signs and symptoms of hypokalemia and notify the provider appropriately
A. furosemide does not affect the blood glucose levels
