Nursing Elites

1. A nurse is reviewing the medical history of a client who has angina. What risk factor should the nurse identify?

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

Correct answer: A

Rationale: The correct answer is A, Hyperlipidemia. Hyperlipidemia, characterized by high levels of lipids in the blood, is a well-established risk factor for the development of angina. Elevated lipid levels can lead to atherosclerosis, which narrows the arteries supplying the heart muscle with oxygenated blood, increasing the risk of angina. Choices B, C, and D are incorrect because COPD, seizure disorder, and hyponatremia are not directly associated with an increased risk of angina.

2. 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.

3. A client with a new diagnosis of type 2 diabetes mellitus is being taught about foot care by a nurse. Which of the following instructions should the nurse include?

• A. Soak your feet in warm water daily.
• B. Wear shoes that are one size larger than your normal size.
• C. Wear cotton socks to keep your feet dry.
• D. Trim your toenails straight across.

Correct answer: D

Rationale: The correct answer is D: "Trim your toenails straight across." This instruction is essential to prevent ingrown toenails in clients with diabetes. Soaking feet in warm water daily (choice A) may increase the risk of skin breakdown and infection. Wearing shoes one size larger than normal (choice B) can lead to friction and cause blisters. While wearing cotton socks (choice C) is generally recommended, the emphasis should be on moisture-wicking materials rather than just cotton.

4. A client has a central venous catheter. Which of the following actions should be taken to prevent an air embolism?

• A. Keep the catheter clamped when not in use
• B. Have the client perform the Valsalva maneuver while the catheter is removed
• C. Use a non-coring needle to access the catheter
• D. Flush the catheter with 0.9% sodium chloride every 24 hours

Correct answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

5. A healthcare professional is reviewing a client's laboratory results. Which of the following values is a contraindication to the administration of heparin?

• A. Hemoglobin 13 g/dL
• B. Platelet count 50,000/mm³
• C. White blood cell count 6,000/mm³
• D. INR 2.5

Correct answer: B

Rationale: The correct answer is B: Platelet count 50,000/mm³. A platelet count of 50,000/mm³ increases the risk of bleeding, making heparin contraindicated. Platelets are essential for blood clotting, and a low count can lead to excessive bleeding. Choices A, C, and D are not contraindications to heparin administration. Hemoglobin level of 13 g/dL is within the normal range, white blood cell count of 6,000/mm³ is also normal, and an INR of 2.5 is within the therapeutic range for patients receiving heparin therapy.
