Nursing Elites

1. Phenytoin is an antiarrhythmic and anticonvulsant that has an unlabeled use for:

• A. Headaches
• B. Cold remedy
• C. Neuropathic pain
• D. Antianxiety

Correct answer: C

Rationale: Phenytoin, an antiarrhythmic and anticonvulsant medication, is also used off-label for treating neuropathic pain. While its primary indications are for managing heart rhythm disorders and seizures, it has shown efficacy in managing neuropathic pain, expanding its clinical utility. Choices A, B, and D are incorrect as phenytoin is not commonly used for headaches, cold remedies, or antianxiety purposes.

2. A client has a new prescription for a Nitroglycerin transdermal patch for Angina Pectoris. Which of the following instructions should the nurse include?

• A. Remove the patch each evening.
• B. Do not cut the patch in half even if angina attacks are under control.
• C. Remove the nitroglycerin patch for 30 minutes if a headache occurs.
• D. Apply a new patch every 48 hours.

Correct answer: A

Rationale: The correct instruction for a client using a Nitroglycerin transdermal patch is to remove the patch each evening to prevent tolerance. This allows for a nitrate-free period of 10 to 12 hours during each 24-hour period, reducing the risk of developing tolerance to the medication. Choice B is incorrect because cutting the patch could alter the dose delivery and is not recommended. Choice C is incorrect as removing the patch for 30 minutes when a headache occurs may not be effective in managing symptoms. Choice D is incorrect as Nitroglycerin patches are usually applied once daily, not every 48 hours.

3. A client with Bipolar disorder has a new prescription for Carbamazepine. Which of the following instructions should the nurse include in the teaching? (Select all that apply.)

• A. This medication can safely be taken during pregnancy.
• B. Eliminate grapefruit juice from your diet.
• C. You will need to have a complete blood count and carbamazepine levels drawn periodically.
• D. Notify your provider if you develop a rash.

Correct answer: B

Rationale: The correct answer is B: "Eliminate grapefruit juice from your diet." Grapefruit juice affects carbamazepine metabolism and should be avoided. It can lead to increased levels of the medication, potentially causing toxicity. Monitoring carbamazepine blood levels and the complete blood count (CBC) is essential to ensure the medication's efficacy and safety. Although choice A is incorrect (This medication can safely be taken during pregnancy), carbamazepine is classified as a Pregnancy Category D drug, which means there is positive evidence of human fetal risk. Choice D (Notify your provider if you develop a rash) is also important because carbamazepine can cause serious adverse effects like Stevens-Johnson syndrome, which can be life-threatening. Regular monitoring and prompt reporting of any rash are crucial. Therefore, choices C and D are also relevant instructions for the client.

4. A client has a new prescription for Verapamil. Which of the following instructions should the nurse include?

• A. Increase your intake of high-fiber foods.
• B. Take the medication with grapefruit juice.
• C. Expect to feel drowsy or lightheaded.
• D. Avoid dairy products while taking this medication.

Correct answer: A

Rationale: The correct instruction to include when a client is prescribed Verapamil is to increase their intake of high-fiber foods. Verapamil can cause constipation as a side effect, and increasing fiber intake can help prevent constipation. High-fiber foods promote bowel regularity and can counteract the constipating effects of Verapamil. Choices B, C, and D are incorrect because taking Verapamil with grapefruit juice can lead to adverse reactions, drowsiness or lightheadedness is not a typical side effect of Verapamil, and there is no need to avoid dairy products specifically while taking this medication.

5. A client is prescribed Clopidogrel. Which of the following laboratory values should be monitored to assess for potential adverse effects?

• A. White blood cell count
• B. Platelet count
• C. Hemoglobin
• D. Blood glucose

Correct answer: B

Rationale: Clopidogrel is an antiplatelet medication, so monitoring the client's platelet count is crucial to assess for potential bleeding complications. Changes in platelet count can indicate an increased risk of bleeding, a known adverse effect of Clopidogrel. Monitoring white blood cell count, hemoglobin, or blood glucose is not directly related to the potential adverse effects of Clopidogrel and would not provide relevant information regarding the medication's impact on platelet function.
