Correct Answer: C

Rationale: A serum potassium level of 5.2 mEq/L indicates hyperkalemia. Spironolactone is a potassium-sparing diuretic that can cause potassium retention. Hyperkalemia is a serious condition that can lead to cardiac dysrhythmias. The healthcare professional should withhold the medication and promptly notify the provider to prevent potential complications.

Correct Answer: B

Rationale: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can increase the risk of bleeding when taken with Warfarin due to its antiplatelet effects. The combination of Warfarin, an anticoagulant, and NSAIDs can potentiate the risk of bleeding complications. Clients on Warfarin should avoid NSAIDs and opt for alternative pain relief options to minimize the risk of adverse effects.

Correct Answer: B

Rationale: Warfarin is contraindicated for a client taking Gingko Biloba due to the potential interaction that can lead to suppressed coagulation and an increased risk of bleeding or hemorrhage. Warfarin is an anticoagulant, and when combined with Gingko Biloba, which also has anticoagulant properties, the risk of bleeding complications is significantly heightened.

Correct Answer: D

Rationale: The correct instruction for taking Colesevelam is to take it with food and at least one glass of water to ensure proper absorption and reduce the risk of gastrointestinal side effects.

Correct Answer: B

Rationale: Coarse tremors are a common sign of Lithium toxicity. Monitoring for tremors is crucial as they can indicate a potentially serious complication that requires immediate intervention. While other options such as severe hypertension, constipation, and muscle spasm may be symptoms of various conditions, they are not typically associated with Lithium toxicity.
