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. A client has a new prescription for enoxaparin. Which of the following instructions should the nurse include?

• A. Massage the injection site after administering the medication.
• B. Pinch the skin while administering the injection.
• C. Administer the medication at bedtime.
• D. Aspirate before injecting the medication.

Correct answer: B

Rationale: When administering enoxaparin, it is important to pinch the skin to ensure proper subcutaneous injection. Massaging the injection site after administering the medication is not recommended. Administering the medication at bedtime is not a specific requirement for enoxaparin. Aspirating before injecting the medication is not necessary for subcutaneous injections like enoxaparin.

3. A nurse is preparing to administer a unit of packed RBCs to a client. Which of the following actions should the nurse take first?

• A. Check the client's identification band
• B. Verify the provider's prescription
• C. Prime the IV tubing with 0.9% sodium chloride
• D. Obtain the client's vital signs

Correct answer: A

Rationale: The correct first action for the nurse to take when preparing to administer a unit of packed RBCs is to check the client's identification band. This step is crucial to ensure that the correct blood is administered to the right client, preventing any errors or adverse reactions. Verifying the provider's prescription, priming the IV tubing, and obtaining the client's vital signs are important steps in the process but should follow the initial identification check to prioritize patient safety.

4. Which laboratory test is essential for monitoring renal function in a patient with chronic kidney disease?

• A. Monitor BUN and creatinine levels
• B. Check blood glucose levels
• C. Monitor hemoglobin and hematocrit levels
• D. Monitor liver enzymes

Correct answer: A

Rationale: The correct answer is to monitor BUN (Blood Urea Nitrogen) and creatinine levels in a patient with chronic kidney disease. These tests provide crucial information about renal function. Checking blood glucose levels (Choice B) is important for monitoring diabetes, not renal function. Monitoring hemoglobin and hematocrit levels (Choice C) helps assess anemia, not specifically renal function. Monitoring liver enzymes (Choice D) is relevant for assessing liver function, not renal function.

5. A client with hypertension is receiving discharge teaching from a nurse on managing blood pressure at home. Which of the following instructions should the nurse include?

• A. Take medication at bedtime.
• B. Check blood pressure once a week.
• C. Use a blood pressure cuff that fits snugly around the arm.
• D. Stop taking medication once blood pressure is within the normal range.

Correct answer: C

Rationale: The correct answer is C: 'Use a blood pressure cuff that fits snugly around the arm.' Using a properly fitting cuff is essential for accurate blood pressure measurements. Choice A is incorrect because the timing of medication administration should be individualized and not specified in the question. Choice B is incorrect as checking blood pressure once a week may not provide sufficient monitoring for a client with hypertension. Choice D is incorrect because stopping medication abruptly once blood pressure is normal can lead to rebound hypertension and complications.
