Nursing Elites

1. 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?

• A. Vitamin K
• B. Calcium carbonate
• C. Acetaminophen
• D. Ranitidine

Correct answer: C

Rationale: The correct answer is Acetaminophen (Choice C). Acetaminophen, especially in high doses, can increase the risk of bleeding in clients taking Warfarin. It can potentiate the anticoagulant effect of Warfarin, leading to an increased risk of bleeding. Vitamin K (Choice A) is actually used to reverse the effects of Warfarin in case of over-anticoagulation, so it does not increase the risk of bleeding. Calcium carbonate (Choice B) and Ranitidine (Choice D) do not significantly interact with Warfarin to increase the risk of bleeding.

2. Which of the following drugs is associated with hepatitis as a reaction?

• A. Valproic acid
• B. Quinidine
• C. Isoniazid
• D. Ethosuximide

Correct answer: C

Rationale: Hepatitis is a known side effect of isoniazid. It is important to monitor patients on isoniazid for signs of liver damage, including hepatitis, as part of their treatment regimen for tuberculosis.

3. When teaching a client with a new prescription for Warfarin, which herbal supplement should the nurse instruct the client to avoid?

• A. St. John's wort
• B. Echinacea
• C. Garlic
• D. Ginseng

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. Echinacea, garlic, and ginseng are not the correct answers in this case. While these herbal supplements may also interact with Warfarin and affect its efficacy, St. John's wort has a well-known interaction with Warfarin that can significantly impact its anticoagulant effects. Educating the client about the specific interaction between St. John's wort and Warfarin is crucial to ensure patient safety and the medication's therapeutic benefit.

4. When should a blood sample be obtained for a peak serum level of gentamicin when administered by IV infusion for 1 hour at 0900?

• A. 1000
• B. 1030
• C. 1100
• D. 1130

Correct answer: B

Rationale: The nurse should obtain the blood sample for the peak serum level at 1030. This timing allows for 30 minutes to elapse after the completion of the 1-hour IV infusion, which is the recommended window for obtaining the peak serum level of gentamicin.

5. A client is being educated about the use of Fluticasone to treat Perennial Rhinitis. Which of the following statements by the client indicates an understanding of the teaching?

• A. I should use the spray every 4 hours while I am awake.
• B. It can take as long as 3 weeks before the medication takes maximum effect.
• C. This medication can also be used to treat motion sickness.
• D. I can use this medication when my nasal passages are blocked.

Correct answer: B

Rationale: The correct answer is B because Fluticasone may show some benefits within a few hours, but its full therapeutic effect may take up to 3 weeks to be achieved in treating Perennial Rhinitis. Option A is incorrect as the frequency of Fluticasone use is usually once daily. Option C is incorrect as Fluticasone is not used for motion sickness. Option D is incorrect as Fluticasone is a preventive medication and not used for immediate relief when nasal passages are blocked.
