Correct Answer: C

Rationale: The correct instruction to include when a client is prescribed Furosemide is to change positions slowly. Furosemide is a diuretic that can lead to orthostatic hypotension, causing dizziness and increasing the risk of falls. By advising the client to change positions slowly, the nurse helps prevent these adverse effects and ensures the client's safety. Option A is incorrect because Furosemide is usually taken in the morning to prevent disturbed sleep due to frequent urination. Option B is incorrect as Furosemide can cause potassium loss, so advising to avoid foods high in potassium would not be appropriate. Option D is incorrect because taking Furosemide with meals may increase the risk of side effects and decrease its effectiveness.

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: 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.

Correct Answer: D

Rationale: Hydrochlorothiazide is a diuretic that can lead to dehydration due to increased urination. Signs of dehydration include dry mouth, increased thirst, and decreased urine output. It is essential to educate the client to monitor these signs and seek medical attention if they occur. Choice A is incorrect because Hydrochlorothiazide is usually taken in the morning to prevent disruption of sleep due to increased urination during the night. Choice B is incorrect because while Hydrochlorothiazide can lead to potassium loss, consuming foods rich in potassium is not a specific instruction related to this medication. Choice C is incorrect because taking Hydrochlorothiazide with a meal is not a specific requirement for its administration.

Correct Answer: D

Rationale: Propranolol is contraindicated in clients with first-degree heart block due to its negative inotropic and chronotropic effects. The nurse should report this finding to the provider to consider an alternative therapy to prevent potential worsening of cardiac conduction abnormalities. Choices A, B, and C are not directly contraindications to Propranolol therapy for migraine headaches and do not pose immediate risks that would require reporting to the provider.
