A client has a new prescription for a Fentanyl transdermal patch. Which of the following instructions should the nurse include?

Correct Answer: C

Rationale: The correct instruction the nurse should include for a client using a Fentanyl transdermal patch is to avoid exposure to heat sources. Heat can increase the absorption of the medication, potentially causing an overdose. Instructing the client to avoid heat sources is crucial to ensure their safety and the effectiveness of the medication. Choices A, B, and D are incorrect because applying the patch to a non-hairy area, changing it every 72 hours, and not cutting the patch are general guidelines for using transdermal patches but do not specifically address the unique risks associated with Fentanyl patches.

Correct Answer: A

Rationale: The correct answer is to instruct the client to avoid taking aspirin while on Clopidogrel. Clopidogrel is an antiplatelet medication that can increase the risk of bleeding. Aspirin and other NSAIDs can further potentiate this risk, so they should be avoided while taking Clopidogrel to reduce the chance of bleeding complications. Choices B, C, and D are incorrect. There is no specific instruction to take Clopidogrel with food or at bedtime. Avoiding foods high in potassium is not directly related to Clopidogrel use.

Correct Answer: A

Rationale: Corrected Rationale: Hydrochlorothiazide, a diuretic, can lead to electrolyte imbalances, particularly hyponatremia (low sodium levels). The nurse should closely monitor the client's sodium levels due to the potential adverse effect of Hydrochlorothiazide. Incorrect Rationales: - Hyperkalemia (Choice B) is less likely to be caused by Hydrochlorothiazide; in fact, it can lead to hypokalemia. - Hypercalcemia (Choice C) is not a common adverse effect of Hydrochlorothiazide. - Hypoglycemia (Choice D) is not directly associated with Hydrochlorothiazide use.

Correct Answer: A

Rationale: Corrected Rationale: Lisinopril is an ACE inhibitor that can cause hyperkalemia by reducing potassium excretion through the kidneys. Monitoring serum potassium levels is crucial to detect hyperkalemia early and prevent adverse effects such as cardiac arrhythmias. Choices B, C, and D are incorrect because Lisinopril is not known to significantly impact sodium, calcium, or magnesium levels in the same way it affects potassium levels.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid taking aspirin while on this medication.' Clopidogrel is an antiplatelet medication that can increase the risk of bleeding. Aspirin and other NSAIDs also affect platelet function and can further increase the risk of bleeding when combined with Clopidogrel. Therefore, it is important for the client to avoid taking aspirin while on this medication to reduce the risk of excessive bleeding. Choices A, C, and D are incorrect because there is no specific requirement to take Clopidogrel with food, avoid foods high in potassium, or take it at bedtime. The key instruction here is to avoid aspirin to prevent potential bleeding complications.
