Nursing Elites

1. A healthcare provider is reviewing the medical history of a client who is scheduled for surgery and takes Warfarin daily. Which of the following laboratory results should the healthcare provider monitor?

• A. Potassium level
• B. INR
• C. BUN
• D. Platelet count

Correct answer: B

Rationale: The INR (International Normalized Ratio) is the most important lab value to monitor in a client taking warfarin. Warfarin is an anticoagulant, and the INR reflects the effectiveness of anticoagulation therapy. Monitoring the INR helps ensure the client is within the therapeutic range to prevent both clotting and bleeding complications.

2. What is the pharmacological action of metformin?

• A. Blocks stimulation of beta1 and beta2.
• B. Blocks vasoconstriction and aldosterone.
• C. Acts at many levels in the CNS to produce an anxiolytic effect.
• D. Decreases hepatic glucose production.

Correct answer: D

Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.

3. When educating a client starting a new prescription for metoprolol, which instruction should the nurse include?

• A. Check your pulse before taking the medication.
• B. Take the medication with food to increase absorption.
• C. Avoid sudden changes in position.
• D. Monitor your blood pressure regularly.

Correct answer: C

Rationale: The correct instruction for a client starting metoprolol is to avoid sudden changes in position. Metoprolol can cause dizziness due to its blood pressure-lowering effects, increasing the risk of falls and injury. Instructing the client to change positions slowly helps prevent orthostatic hypotension and related adverse events. Checking the pulse before taking the medication (Choice A) is not typically necessary for metoprolol. Taking the medication with food (Choice B) is not required for absorption and can be taken with or without food. Monitoring blood pressure regularly (Choice D) is essential for clients taking metoprolol, but avoiding sudden changes in position is more critical to prevent dizziness and falls.

4. When educating a client who has a prescription for Levothyroxine, which instruction should the nurse include?

• A. Take this medication on an empty stomach.
• B. Take this medication with food.
• C. Take this medication at bedtime.
• D. Take this medication with antacids.

Correct answer: A

Rationale: The correct instruction for taking Levothyroxine is on an empty stomach. This helps to enhance the absorption and effectiveness of the medication. Consuming it with food or antacids can impede its absorption, leading to decreased efficacy.

5. When educating a client who has a prescription for Propranolol, what instruction should the healthcare provider include?

• A. Take this medication with food.
• B. Discontinue the medication if you feel fatigued.
• C. Expect to have decreased heart rate with this medication.
• D. Do not stop taking this medication abruptly.

Correct answer: D

Rationale: The correct instruction for a client with a prescription for Propranolol is not to stop taking the medication abruptly. Abrupt cessation can result in rebound hypertension or other cardiac complications. It is crucial for the client to taper off the medication gradually under healthcare provider supervision to prevent adverse effects. Choice A is incorrect because Propranolol can be taken with or without food. Choice B is incorrect as discontinuing the medication based on fatigue alone is not advisable without consulting a healthcare provider. Choice C is incorrect because while Propranolol can decrease heart rate, it is not the primary instruction to provide in this scenario.
