Nursing Elites

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

• A. Take this medication at bedtime.
• B. Monitor for signs of hyperglycemia.
• C. Avoid drinking grapefruit juice.
• D. Increase your intake of potassium-rich foods.

Correct answer: C

Rationale: The correct answer is to instruct the client to avoid drinking grapefruit juice. Grapefruit juice can inhibit the metabolism of Verapamil, leading to increased blood levels of the medication, which can potentiate its effects, potentially causing adverse reactions like hypotension and bradycardia. Choices A, B, and D are incorrect. Taking Verapamil at bedtime is not a specific instruction related to its metabolism or side effects. Monitoring for signs of hyperglycemia is not directly related to Verapamil use. Increasing potassium-rich foods intake is not necessary with Verapamil and could potentially lead to hyperkalemia in some cases.

2. A client prescribed Isosorbide Mononitrate for chronic stable Angina develops reflex tachycardia. Which of the following medications should the nurse expect to administer?

• A. Furosemide
• B. Captopril
• C. Ranolazine
• D. Metoprolol

Correct answer: D

Rationale: Metoprolol, a beta-adrenergic blocker, is commonly used to treat hypertension and stable angina pectoris. It is often prescribed to decrease heart rate in clients experiencing tachycardia, including those with reflex tachycardia induced by medications like Isosorbide Mononitrate. Furosemide (Choice A) is a diuretic and is not indicated for reflex tachycardia. Captopril (Choice B) is an ACE inhibitor used for hypertension and heart failure, not tachycardia. Ranolazine (Choice C) is used in chronic angina but does not address tachycardia.

3. 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.

4. A client with thrombophlebitis receiving heparin by continuous IV infusion asks the nurse how long it will take for the heparin to dissolve the clot. Which of the following responses should the nurse give?

• A. It usually takes heparin at least 2 to 3 days to reach a therapeutic blood level.
• B. A pharmacist is the person to answer that question.
• C. Heparin does not dissolve clots. It stops new clots from forming.
• D. The oral medication you will take after this IV will dissolve the clot.

Correct answer: C

Rationale: The correct response is C. Heparin does not dissolve clots; it prevents new clots from forming. Heparin works by inhibiting the formation of new clots and the extension of existing clots, rather than directly dissolving them. The client should be informed that the purpose of heparin therapy is to prevent the clot from getting larger and to reduce the risk of new clots forming. Choices A, B, and D are incorrect. Choice A talks about reaching a therapeutic blood level of heparin, which is not related to clot dissolution. Choice B deflects the question to a pharmacist without providing relevant information. Choice D inaccurately suggests that an oral medication will dissolve the clot, which is not the mechanism of action for heparin.

5. What are the actions of the drug metformin?

• A. Decreases hepatic glucose production and intestinal glucose absorption
• B. Increases sensitivity to insulin
• C. Short-term sedation
• D. Both A and B

Correct answer: D

Rationale: Metformin has dual actions by decreasing hepatic glucose production and intestinal glucose absorption, which helps in reducing blood glucose levels. Additionally, it increases sensitivity to insulin, aiding in its proper utilization within the body. Choice A is correct as metformin acts by decreasing hepatic glucose production and intestinal glucose absorption. Choice B is also correct as metformin increases sensitivity to insulin. Choice C, short-term sedation, is incorrect as metformin is not known for causing sedation. Therefore, the correct answer is D because metformin performs both of these actions.
