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: D

Rationale: When a client is receiving cyclophosphamide, the nurse should monitor for hemorrhagic cystitis, a severe adverse effect caused by bladder irritation. It is essential to watch for signs such as hematuria, dysuria, and urinary frequency, and promptly intervene to prevent further complications.

Correct Answer: C

Rationale: The nurse should instruct the client to report a sore throat because it can indicate an infection due to the immunosuppressive effects of topotecan. Monitoring for signs of infection is crucial to prevent complications during therapy.

Correct Answer: C

Rationale: The correct answer is C: Delirium. When IV Nitroprusside is infused at high dosages, it can lead to thiocyanate toxicity, causing mental status changes such as delirium. It is crucial to monitor the thiocyanate levels to ensure they remain below 10 mg/dL during therapy to prevent adverse effects.

Correct Answer: C

Rationale: The correct answer is Acetaminophen. Acetaminophen, especially in high doses, can increase the risk of bleeding in clients taking warfarin. It is important to monitor for signs of bleeding when these medications are used concurrently to prevent adverse effects.
