Nursing Elites

1. Which lab value is critical for patients on warfarin therapy?

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

Correct answer: A

Rationale: The correct answer is to monitor INR levels for patients on warfarin therapy. INR monitoring is essential because it helps assess the clotting tendency of the blood and ensures that patients are within the therapeutic range to prevent both blood clots and excessive bleeding. Monitoring potassium levels (Choice B), sodium levels (Choice C), or platelet count (Choice D) is not specifically required for patients on warfarin therapy and does not directly impact the effectiveness or safety of the medication.

2. A client is receiving heparin therapy. Which of the following laboratory results indicates the client is receiving an effective dose of heparin?

• A. INR 1.5
• B. aPTT 60 seconds
• C. Platelets 150,000/mm³
• D. Potassium 4.0 mEq/L

Correct answer: B

Rationale: An aPTT of 60 seconds indicates the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for a clot to form, and a therapeutic range for heparin therapy is usually 1.5 to 2 times the control value, which is around 60-80 seconds. An INR of 1.5 is not related to heparin therapy, as it is commonly used to monitor warfarin therapy. Platelet count and potassium levels are not direct indicators of the effectiveness of heparin therapy.

3. A client with vision loss is being cared for by a nurse. Which of the following actions should the nurse take?

• A. Keep objects in the client's room in the same place
• B. Ensure there is high-wattage lighting in the client's room
• C. Approach the client from the side
• D. Touch the client gently to announce presence

Correct answer: A

Rationale: The correct action for the nurse to take is to keep objects in the client's room in the same place. This helps individuals with vision loss navigate their environment more easily by creating a familiar and consistent layout. Choice B, ensuring high-wattage lighting, may not be suitable for all clients with vision loss and can cause discomfort or glare. Approaching the client from the side (Choice C) can startle them and is not recommended. Touching the client (Choice D) without warning may cause anxiety or distress, so it's important to announce presence verbally.

4. A nurse is preparing to administer a rectal suppository to a client. What action should the nurse take?

• A. Encourage the client to hold their breath as long as possible.
• B. Insert the suppository just past the anal sphincter.
• C. Lubricate the suppository and insert it 1.5 cm (0.6 in) into the rectum.
• D. Place the client in a Sims' position before inserting the suppository.

Correct answer: D

Rationale: The correct action the nurse should take when administering a rectal suppository is to place the client in a Sims' position. This position helps facilitate the proper administration of the suppository by allowing better access to the rectum. Encouraging the client to hold their breath as long as possible (Choice A) is unnecessary and not related to the administration of a rectal suppository. Inserting the suppository just past the anal sphincter (Choice B) is incorrect as it may not reach the rectum where it needs to be placed. Lubricating the suppository and inserting it 1.5 cm into the rectum (Choice C) is incorrect as the suppository needs to be inserted deeper into the rectum for proper absorption.

5. A nurse is caring for a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min, and the PR interval is 0.24 seconds. What cardiac rhythm should the nurse interpret this finding as?

• A. First-degree AV block.
• B. Premature ventricular contraction.
• C. Sinus bradycardia.
• D. Atrial fibrillation.

Correct answer: A

Rationale: The correct answer is A: First-degree AV block. A PR interval of 0.24 seconds indicates a prolonged PR interval, which is characteristic of first-degree AV block. This rhythm is considered benign and often does not require treatment. Choice B, premature ventricular contraction, is characterized by early, abnormal ventricular contractions and would not be indicated by the findings provided. Choice C, sinus bradycardia, would present with a normal PR interval but a heart rate less than 60 beats per minute. Choice D, atrial fibrillation, is characterized by an irregularly irregular rhythm with no identifiable P waves, which does not align with the findings of a prolonged PR interval in this scenario.
