Nursing Elites

1. What is the primary purpose of administering anticoagulants to a patient with atrial fibrillation?

• A. To reduce blood pressure.
• B. To prevent clot formation.
• C. To prevent arrhythmias.
• D. To reduce inflammation.

Correct answer: B

Rationale: The primary purpose of administering anticoagulants to a patient with atrial fibrillation is to prevent clot formation. Patients with atrial fibrillation are at an increased risk of forming blood clots in the heart, which can lead to stroke if they travel to the brain. Anticoagulants help to reduce this risk by inhibiting the clotting process. Therefore, choices A, C, and D are incorrect because anticoagulants do not primarily aim to reduce blood pressure, prevent arrhythmias, or reduce inflammation in patients with atrial fibrillation.

2. A client has undergone insertion of a permanent pacemaker. When developing a discharge teaching plan, the nurse writes a goal of, 'The client will verbalize symptoms of pacemaker failure.' Which symptoms are most important to teach the client?

• A. Facial flushing.
• B. Fever.
• C. Pounding headache.
• D. Feelings of dizziness.

Correct answer: D

Rationale: The correct answer is 'D: Feelings of dizziness.' Feelings of dizziness may occur as a result of a decreased heart rate, leading to decreased cardiac output, which can be an indication of pacemaker failure. Teaching the client to recognize symptoms of decreased cardiac output, like dizziness, is crucial for early detection of pacemaker malfunction. Choices A, B, and C are less specific to pacemaker failure and are not commonly associated with this condition. Facial flushing, fever, and pounding headache are not typical signs of pacemaker failure and are not directly related to cardiac output, making them less relevant for teaching the client about pacemaker failure.

3. During spring break, a young adult presents to the urgent care clinic and reports a stiff neck, a fever for the past 6 hours, and a headache. Which intervention is most important for the nurse to implement first?

• A. Initiate isolation precautions
• B. Administer an antipyretic
• C. Draw blood cultures
• D. Prepare for lumbar puncture

Correct answer: A

Rationale: The correct answer is to initiate isolation precautions. This is the priority action because the patient presents with symptoms that could be indicative of meningitis, an infectious disease that requires isolation to prevent its spread. Administering an antipyretic (Choice B) may help manage the fever but does not address the need for isolation. Drawing blood cultures (Choice C) and preparing for a lumbar puncture (Choice D) are important steps in diagnosing meningitis but should come after initiating isolation precautions to prevent potential transmission of the infection to others.

4. Oxygen via nasal cannula has been prescribed for a client with emphysema. The nurse checks the physician’s orders to ensure that the prescribed flow is not greater than:

• A. 1 L/min
• B. 3 L/min
• C. 4 L/min
• D. 6 L/min

Correct answer: B

Rationale: The correct answer is B, 3 L/min. Clients with emphysema typically receive oxygen at a flow rate of 1 to 2 L/min, with a maximum of 3 L/min. Higher flow rates can lead to oxygen toxicity in these clients, so it's crucial to adhere to the prescribed limits. Choice A (1 L/min) is too low and may not provide adequate oxygenation for the client. Choices C (4 L/min) and D (6 L/min) exceed the recommended flow rates for clients with emphysema and can increase the risk of oxygen toxicity.

5. A patient asks the nurse about taking calcium supplements to avoid hypocalcemia. The nurse will suggest that the patient follow which instruction?

• A. Take a calcium and vitamin D combination supplement.
• B. Take calcium along with phosphorus to improve absorption.
• C. Take calcium with antacids to reduce stomach upset.
• D. Use aspirin instead of acetaminophen when taking calcium.

Correct answer: A

Rationale: The correct answer is to take a calcium and vitamin D combination supplement. Vitamin D enhances the absorption of calcium in the body, making it an essential component for calcium utilization. Choice B is incorrect because calcium and phosphorus have an inverse relationship, where an increased level of one mineral decreases the level of the other, so taking them together may not be beneficial. Choice C is incorrect because antacids often contain magnesium, which can promote calcium loss instead of absorption. Choice D is incorrect because aspirin can alter vitamin D levels and interfere with calcium absorption, so it is not recommended when taking calcium supplements.
