A client has a new prescription for Warfarin. The nurse should identify that the concurrent use of which of the following medications increases the client's risk of bleeding?

Correct Answer: C

Rationale: In this scenario, the correct answer is C) Acetaminophen. Acetaminophen is known to potentiate the effects of Warfarin, increasing the risk of bleeding in the client. Acetaminophen can interfere with the metabolism of Warfarin, leading to higher levels of Warfarin in the blood and subsequently increasing the risk of bleeding complications. Option A) Vitamin K is incorrect because Vitamin K actually antagonizes the effects of Warfarin by promoting clotting factors' synthesis. Calcium carbonate (Option B) and Ranitidine (Option D) do not have significant interactions with Warfarin that would increase the risk of bleeding. Educationally, understanding drug interactions is crucial in pharmacology to ensure safe and effective medication management for patients. Nurses need to be aware of potential interactions to prevent adverse drug events and optimize patient outcomes. It is essential to educate patients about the importance of disclosing all medications, including over-the-counter drugs like Acetaminophen, to healthcare providers when starting a new prescription like Warfarin.

Correct Answer: C

Rationale: The correct answer is C. Erythromycin should be taken on an empty stomach with a full glass of water to increase absorption. Taking it with milk (choice A) or an antacid (choice D) can interfere with its absorption. Avoiding direct sunlight (choice B) is not directly related to the administration of erythromycin.

Correct Answer: B

Rationale: The correct answer is B) You should stop taking this medication if you develop a rash. This information is crucial because ceftriaxone is known to cause severe allergic reactions, including skin rashes, which can be a sign of a serious adverse event like Stevens-Johnson syndrome. Discontinuing the medication and seeking medical attention promptly can prevent further complications and ensure the client's safety. Option A is incorrect because a cough is not a common side effect of ceftriaxone. Option C is also incorrect because ceftriaxone is primarily administered via intramuscular or intravenous routes, not orally. Option D is incorrect as well because while ceftriaxone can cause the urine to turn a reddish color, not yellow. In an educational context, it is essential for nurses to understand the potential side effects and adverse reactions of medications to educate clients effectively. Teaching clients to watch for specific signs and symptoms, like a rash in the case of ceftriaxone, empowers them to take an active role in their healthcare and seek timely medical intervention when necessary.

Correct Answer: D

Rationale: The client's symptoms of face spasms after receiving Prochlorperazine indicate acute dystonia, a known side effect. Diphenhydramine is commonly administered to manage extrapyramidal symptoms, such as muscle spasms, caused by medications like Prochlorperazine. Therefore, the nurse should anticipate a prescription for Diphenhydramine to alleviate the client's symptoms.

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.
