Nursing Elites

1. Which diagnostic test is used to confirm tuberculosis (TB) infection?

• A. Chest X-ray
• B. Sputum culture
• C. Skin test (Mantoux)
• D. MRI

Correct answer: C

Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.

2. What is the appropriate diet for a patient with chronic kidney disease?

• A. Low protein diet
• B. High protein diet
• C. Low sodium diet
• D. Low potassium diet

Correct answer: A

Rationale: A low protein diet is the appropriate choice for a patient with chronic kidney disease because it helps to reduce the buildup of waste products in the body, which the kidneys may struggle to filter out. High protein diets can put extra strain on the kidneys by increasing the workload to eliminate the byproducts of protein metabolism. While low sodium and low potassium diets can also be important for managing certain aspects of kidney disease, the primary focus should be on controlling protein intake to lessen the burden on the kidneys.

3. A nurse is caring for a client who has a tracheostomy. Which of the following actions should the nurse take when providing tracheostomy care?

• A. Use sterile technique when performing tracheostomy care.
• B. Replace the tracheostomy ties every 24 hours.
• C. Use a sterile brush to clean the inner cannula.
• D. Change the tracheostomy dressing once a week.

Correct answer: C

Rationale: The correct answer is to use a sterile brush to clean the inner cannula. This action is crucial to prevent infection during tracheostomy care. Choice A is incorrect as clean technique is not adequate for tracheostomy care, sterile technique is required. Choice B is incorrect as tracheostomy ties should be replaced when soiled, not routinely every 24 hours. Choice D is incorrect as tracheostomy dressings should be changed more frequently to maintain cleanliness and prevent infection.

4. A nurse is planning care for a client who is 1 day postoperative following a total knee arthroplasty. Which of the following interventions should the nurse include?

• A. Keep the affected leg elevated as needed.
• B. Apply ice packs to the affected knee as prescribed.
• C. Encourage the client to ambulate as soon as possible.
• D. Perform range-of-motion exercises as instructed.

Correct answer: C

Rationale: Encouraging the client to ambulate as soon as possible is essential in preventing complications like deep vein thrombosis post knee arthroplasty. While keeping the affected leg elevated and applying ice packs can be beneficial in certain situations, early ambulation takes precedence in this case. Performing range-of-motion exercises hourly may not be necessary and could potentially cause more harm than good if not done correctly or excessively.

5. A nurse is providing teaching to a client who is at 36 weeks of gestation and is scheduled for a nonstress test. Which of the following instructions should the nurse include?

• A. The test will last about 30 minutes.
• B. You should drink a full glass of water prior to the test.
• C. You will need to have your bladder full for this test.
• D. This test measures how well your baby's heart responds to movement.

Correct answer: D

Rationale: The correct answer is D. A nonstress test measures the fetal heart's response to movement, helping to assess fetal well-being. Choice A is incorrect as the duration of the test can vary, and it is not always precisely 30 minutes. Choice B is incorrect as drinking water is not necessary for a nonstress test. Choice C is incorrect as having a full bladder is not required for this test.
