ATI Pharmacology Proctored Exam 2023

Correct Answer: A

Rationale: The correct answer is St. John's wort. St. John's wort can reduce the effectiveness of Warfarin by interacting with its metabolism, potentially leading to decreased anticoagulant effects. Therefore, the nurse should instruct the client to avoid using St. John's wort while taking Warfarin to prevent adverse drug interactions. Additionally, it is essential to educate the client about other herbal supplements like garlic and ginseng, which may also interact with Warfarin and should be avoided to ensure the medication's efficacy and safety.

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: C

Rationale: The correct answer is to instruct the client to avoid drinking grapefruit juice. Grapefruit juice can inhibit the metabolism of Verapamil, leading to increased blood levels of the medication, which can potentiate its effects, potentially causing adverse reactions like hypotension and bradycardia.

Correct Answer: C

Rationale: The correct answer is C: Delirium. When IV nitroprusside is administered at high dosages, it can lead to thiocyanate toxicity, resulting in mental status changes such as delirium. Monitoring thiocyanate levels during therapy is crucial to ensure they remain below 10 mg/dL to prevent this adverse reaction.

Correct Answer: C

Rationale: Capecitabine is known to cause neutropenia as a common adverse effect due to bone marrow suppression. Neutropenia increases the risk of infections and requires close monitoring to prevent complications.
