Nursing Elites

1. A nurse is preparing to teach a client about the use of a peak flow meter. Which of the following instructions should the nurse include?

• A. Place the mouthpiece in your mouth and blow out as quickly as you can.
• B. Exhale slowly into the mouthpiece over 5 seconds.
• C. Take a slow deep breath before blowing into the mouthpiece.
• D. Blow into the mouthpiece at a steady rate for 3 seconds.

Correct answer: A

Rationale: The correct instruction for using a peak flow meter is to place the mouthpiece in your mouth and blow out as quickly as you can. This action helps measure the peak expiratory flow of the client. Choice B is incorrect because exhaling slowly does not provide an accurate peak flow reading. Choice C is incorrect as taking a slow deep breath before blowing interferes with obtaining an accurate measurement. Choice D is incorrect as blowing at a steady rate for 3 seconds may not reflect the peak expiratory flow accurately.

2. Which lab value should be monitored in patients receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor platelet count
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT in patients receiving heparin therapy. Activated Partial Thromboplastin Time (aPTT) is crucial to assess the therapeutic effectiveness of heparin and to prevent bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy, not heparin. Platelet count (Choice C) monitoring is essential for detecting heparin-induced thrombocytopenia rather than assessing heparin therapy itself. Monitoring sodium levels (Choice D) is not directly related to heparin therapy monitoring.

3. A nurse is assessing a client who is receiving a continuous heparin infusion. Which of the following findings should the nurse report to the provider?

• A. Platelet count of 200,000/mm³
• B. aPTT of 50 seconds
• C. Hemoglobin of 14 g/dL
• D. INR of 1.0

Correct answer: D

Rationale: The correct answer is D because an INR of 1.0 is below the therapeutic range for clients receiving heparin, indicating a potential need for dosage adjustment. Platelet count (choice A) within normal range, aPTT (choice B) within therapeutic range, and hemoglobin level (choice C) are not directly related to the monitoring of heparin therapy and would not require immediate reporting to the provider.

4. How should a healthcare provider monitor a patient who has been prescribed digoxin?

• A. Monitor potassium levels
• B. Monitor heart rate
• C. Check digoxin levels
• D. Check blood glucose levels

Correct answer: C

Rationale: The correct way to monitor a patient who has been prescribed digoxin is by checking digoxin levels. Digoxin is a medication used to treat various heart conditions, and monitoring its levels in the blood is crucial to prevent toxicity. Monitoring potassium levels (Choice A) is important as well, as digoxin can affect potassium levels, but checking digoxin levels is more specific to monitoring the medication itself. Monitoring heart rate (Choice B) is relevant but does not directly assess the medication levels. Checking blood glucose levels (Choice D) is not typically indicated specifically for patients prescribed digoxin.

5. A nurse is planning care for a client who has a new prescription for a peripheral intravenous (IV) catheter. Which of the following actions should the nurse take to prevent infection?

• A. Shave the hair at the insertion site.
• B. Cleanse the site with povidone-iodine.
• C. Wear sterile gloves when changing the dressing.
• D. Change the IV site every 48 to 72 hours.

Correct answer: D

Rationale: The correct action to prevent infection when caring for a client with a new peripheral IV catheter is to change the IV site every 48 to 72 hours. Shaving the hair at the insertion site can actually increase the risk of infection by causing microabrasions in the skin. While cleansing the site with povidone-iodine is important before insertion, it is not necessary to continue doing so once the IV is in place. Wearing sterile gloves when changing the dressing is crucial for maintaining aseptic technique but does not directly prevent infection related to the IV site itself.
