Nursing Elites

1. A nurse reviewing a client's medical record notes a new prescription for verifying the trough level of the client's medication. Which of the following actions should the nurse take?

• A. Obtain a blood specimen immediately prior to administering the next dose of medication.
• B. Verify that the client has been taking the medication for 24 hours before obtaining a blood specimen.
• C. Ask the client to provide a urine specimen after the next dose of medication.
• D. Administer the medication and obtain a blood specimen 30 minutes later.

Correct answer: A

Rationale: To verify the trough levels of a medication accurately, the nurse should obtain a blood specimen immediately before administering the next dose of the medication. The trough level represents the lowest concentration of the medication in the bloodstream, typically right before the next dose is due. This timing ensures an accurate assessment of the drug's concentration in the body at its lowest point, aiding in determining the drug's effectiveness and potential toxicity levels. Choice B is incorrect because waiting for 24 hours would not provide the trough level. Choice C is incorrect as urine specimens are not used to measure trough levels. Choice D is incorrect as obtaining a blood specimen 30 minutes after administering the medication would not reflect the trough level.

2. What is the action of Metformin?

• A. Decreasing intestinal glucose absorption
• B. Increasing sensitivity to insulin
• C. Decreasing hepatic glucose production
• D. All of the above

Correct answer: D

Rationale: Metformin exerts its effects by decreasing hepatic glucose production, increasing sensitivity to insulin, and decreasing intestinal glucose absorption. These actions help in lowering blood glucose levels and improving insulin sensitivity in individuals with diabetes.

3. A client in an acute care facility is receiving IV Nitroprusside for hypertensive crisis. The nurse should monitor the client for which of the following adverse reactions to this medication?

• A. Intestinal ileus
• B. Neutropenia
• C. Delirium
• D. Hyperthermia

Correct answer: C

Rationale: The correct answer is C: Delirium. When IV Nitroprusside is infused at high dosages, it can lead to thiocyanate toxicity, causing mental status changes such as delirium. It is crucial to monitor the thiocyanate levels to ensure they remain below 10 mg/dL during therapy to prevent adverse effects. Choices A, B, and D are incorrect because IV Nitroprusside is not commonly associated with intestinal ileus, neutropenia, or hyperthermia. Monitoring for delirium is crucial due to the risk of thiocyanate toxicity.

4. When using Nitroglycerine (transdermal), how many hours should you be nitrate-free each day?

• A. 1-2 hours
• B. 5-10 hours
• C. 3-4 hours
• D. 10-12 hours

Correct answer: D

Rationale: When using Nitroglycerine (transdermal), it should be applied for 10-12 hours per day to ensure its effectiveness. A nitrate-free period within the day is essential to prevent the development of tolerance to the medication.

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

• A. Monitor for signs of bleeding.
• B. Avoid foods high in vitamin K.
• C. Expect to have increased urination.
• D. Take the medication with an antacid.

Correct answer: A

Rationale: The correct instruction for a client starting Warfarin is to monitor for signs of bleeding. Warfarin is an anticoagulant that increases the risk of bleeding; therefore, it is crucial for the client to watch for any signs of bleeding, such as easy bruising, prolonged bleeding from cuts, blood in urine or stools, or unusual bleeding from gums or nose. If any of these signs occur, the client should promptly report them to their healthcare provider for further evaluation and management. Choices B, C, and D are incorrect because avoiding foods high in vitamin K is related to other medications like Coumadin, increased urination is not a common side effect of Warfarin, and taking Warfarin with an antacid can potentially interfere with its absorption.
