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

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 nurse is caring for an infant who has a prescription for continuous pulse oximetry. Which of the following is an appropriate action for the nurse to take?

Correct answer: B

Rationale: The correct answer is to move the probe site every 3 hours. This action helps prevent skin breakdown and ensures accurate readings. Placing the infant under a radiant warmer (Choice A) is not necessary for pulse oximetry monitoring. Heating the skin before placing the probe (Choice C) can potentially cause burns in infants. Placing a sensor on the index finger (Choice D) is not the standard practice for continuous pulse oximetry in infants.

3. A nurse is assessing a client who has dehydration. Which of the following findings should the nurse expect?

Correct answer: C

Rationale: The correct answer is C: Tachycardia. Tachycardia is a common sign of dehydration because the body tries to compensate for the reduced fluid volume by increasing the heart rate. Bradycardia (choice A) is not typically seen in dehydration as the body tries to maintain perfusion. Increased skin turgor (choice B) is actually a sign of dehydration, but tachycardia is a more specific finding. A bounding pulse (choice D) is associated with conditions like hyperthyroidism or aortic regurgitation, not dehydration.

4. A nurse is teaching a client who has heart failure about a new prescription for furosemide. Which of the following statements should the nurse include?

Correct answer: C

Rationale: The correct statement to include when teaching a client about furosemide is that it may cause potassium levels to decrease. Furosemide is a loop diuretic that can lead to hypokalemia, emphasizing the importance of monitoring potassium levels. Option A is incorrect because furosemide is usually taken in the morning to prevent nighttime diuresis. Option B is incorrect as tinnitus, not ringing in the ears, is associated with furosemide use. Option D is wrong because while it is essential to monitor potassium levels, the client should be advised to consume foods high in potassium to prevent hypokalemia.

5. A nurse is caring for a client who is 1 hr postoperative following a transurethral resection of the prostate (TURP). The nurse notes that the client's indwelling urinary catheter has not drained in the past hour. Which of the following actions should the nurse take?

Correct answer: A

Rationale: In this situation, the nurse should irrigate the catheter with 0.9% sodium chloride to help relieve any obstruction and ensure proper urinary drainage following a TURP. Repositioning the catheter may not address the underlying issue of obstruction. Notifying the provider should be done after attempting to resolve the drainage issue. Increasing the rate of continuous bladder irrigation is not the initial intervention for a catheter that is not draining.
