Nursing Elites

1. What lab value should a healthcare provider monitor for a patient on warfarin therapy?

• A. Potassium
• B. PT/INR
• C. Sodium
• D. Calcium

Correct answer: B

Rationale: The correct answer is B: PT/INR. When a patient is on warfarin therapy, healthcare providers monitor the PT/INR levels to evaluate the effectiveness of the treatment and assess the risk of bleeding. Monitoring potassium, sodium, or calcium levels is not directly related to warfarin therapy and would not provide the necessary information needed to manage the medication effectively.

2. A client who has a new diagnosis of tuberculosis should be placed in which type of room to prevent the spread of airborne pathogens?

• A. Administer isoniazid by mouth daily.
• B. Place the client in droplet isolation.
• C. Wear a surgical mask when transporting the client.
• D. Place the client in a negative pressure room.

Correct answer: D

Rationale: Clients diagnosed with tuberculosis should be placed in a negative pressure room to prevent the spread of airborne pathogens. Option A is incorrect because administering isoniazid is a treatment for tuberculosis, not a preventive measure related to infection control. Option B is incorrect as droplet isolation is used for diseases transmitted through respiratory droplets, not airborne pathogens like tuberculosis. Option C is incorrect as wearing a surgical mask is not sufficient to prevent the spread of tuberculosis in healthcare settings; placing the client in a negative pressure room is the most effective measure.

3. A nurse is reviewing the medical history of a client who has angina. Which of the following findings in the client's medical history should the nurse identify as a risk factor for angina?

• A. Hyperlipidemia.
• B. COPD.
• C. Seizure disorder.
• D. Hyponatremia.

Correct answer: A

Rationale: The correct answer is A: Hyperlipidemia. Hyperlipidemia, which is an elevated level of lipids (fats) in the blood, is a well-established risk factor for angina. High levels of lipids can lead to atherosclerosis, a condition where fatty deposits build up in the arteries, reducing blood flow to the heart muscle and increasing the risk of angina. Choice B, COPD (Chronic Obstructive Pulmonary Disease), is not directly linked to an increased risk of angina. COPD primarily affects the lungs and is not a known risk factor for angina. Choice C, Seizure disorder, and Choice D, Hyponatremia (low sodium levels), are also not typically associated with an increased risk of angina. While medical conditions like hypertension, diabetes, and smoking are other common risk factors for angina, hyperlipidemia is specifically known for its impact on blood vessels, making it a key risk factor to identify in a client's medical history.

4. A client with asthma asks how to use a peak flow meter. Which of the following instructions should the nurse provide?

• A. Use the peak flow meter at the same time each day.
• B. Take a slow, deep breath and blow out as hard as you can.
• C. Keep a log of your peak flow readings.
• D. Perform the test before using any bronchodilators.

Correct answer: D

Rationale: The correct answer is to instruct the client to perform the peak flow test before using any bronchodilators. This is important because it provides the most accurate baseline measurement of lung function. Choice A is not necessarily crucial for the accuracy of the test. Choice B describes the technique for spirometry, not peak flow meter use. Choice C, while important for tracking trends, is not directly related to the accuracy of the initial measurement.

5. What is the appropriate nursing action for a patient experiencing an acute allergic reaction?

• A. Administer antihistamines
• B. Administer corticosteroids
• C. Administer oxygen
• D. Administer bronchodilators

Correct answer: A

Rationale: The appropriate nursing action for a patient experiencing an acute allergic reaction is to administer antihistamines. Antihistamines work by blocking the action of histamine, a chemical released during an allergic reaction, and can help relieve symptoms such as itching, swelling, and hives. Corticosteroids are used for severe allergic reactions not responding to antihistamines, as they have anti-inflammatory properties. Oxygen is administered in cases of respiratory distress, while bronchodilators are used for bronchospasms. However, the first-line intervention for an acute allergic reaction is antihistamines.
