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 nurse is planning to teach a group of clients about preventing low back pain. Which of the following information should the nurse include?

• A. Wear low-heeled shoes.
• B. Elevate the legs while sitting.
• C. Engage in prolonged sitting to rest the back muscles.
• D. Sleep on a soft mattress to prevent strain on the back.

Correct answer: A

Rationale: The correct answer is A: 'Wear low-heeled shoes.' Wearing low-heeled shoes helps prevent back strain by promoting proper posture. High heels can cause an imbalance in the body's alignment, leading to increased stress on the lower back. Choices B, C, and D are incorrect. Elevating the legs while sitting can help with circulation but does not directly prevent low back pain. Engaging in prolonged sitting can actually contribute to low back pain due to decreased muscle activity and increased pressure on the spine. Sleeping on a soft mattress may not provide adequate support for the back, potentially worsening back pain instead of preventing it.

3. A nurse is caring for a client who is at risk for developing pressure ulcers. Which of the following interventions should the nurse implement?

• A. Use a donut-shaped cushion for sitting
• B. Turn the client every 4 hours
• C. Elevate the head of the bed to 45 degrees
• D. Massage reddened areas to increase circulation

Correct answer: C

Rationale: Elevating the head of the bed reduces pressure on bony prominences, which helps prevent pressure ulcers.

4. What is the priority intervention for a patient with dehydration?

• A. Administer IV fluids
• B. Monitor intake and output
• C. Administer oral fluids
• D. Provide electrolyte replacement

Correct answer: A

Rationale: The correct answer is to administer IV fluids. This intervention is the priority as it helps rapidly restore hydration in patients with dehydration by delivering fluids directly into the bloodstream. Monitoring intake and output (choice B) is important but comes after providing immediate fluid resuscitation. Administering oral fluids (choice C) may not be sufficient for a patient with dehydration who requires rapid rehydration. Providing electrolyte replacement (choice D) is essential but often follows fluid resuscitation to correct any electrolyte imbalances resulting from dehydration.

5. A nurse is providing discharge teaching to a client who is postoperative following a hip arthroplasty. Which of the following statements indicates a need for further teaching?

• A. I will avoid sitting in a recliner while recovering.
• B. I will bend at the waist to pick up items from the floor.
• C. I will use a pillow between my legs when lying on my side.
• D. I will avoid crossing my legs when sitting.

Correct answer: B

Rationale: The correct answer is B. Bending at the waist can increase the risk of dislocation following hip arthroplasty. This movement can put strain on the hip joint and potentially lead to complications. Choices A, C, and D are all correct statements that promote proper postoperative care and help prevent complications. Sitting in a recliner, using a pillow between the legs when lying on the side, and avoiding crossing legs when sitting are all appropriate instructions for a client recovering from hip arthroplasty.
