1. A nurse is caring for a client who is postoperative following a hip arthroplasty. Which of the following actions should the nurse take to prevent dislocation of the prosthesis?

A. Place a pillow between the client's legs.
B. Place the client in a high Fowler's position.
C. Maintain the client in a side-lying position.
D. Keep the client's legs elevated.

Correct answer: A

Rationale: Placing a pillow between the client's legs is the correct action to prevent dislocation of the prosthesis after hip arthroplasty. This positioning helps maintain proper alignment and stability of the hip joint, reducing the risk of dislocation. Placing the client in a high Fowler's position (choice B) is not recommended after hip arthroplasty as it may strain the hip joint. Maintaining the client in a side-lying position (choice C) or keeping the client's legs elevated (choice D) does not provide the same level of support and alignment as placing a pillow between the legs.

2. A nurse is assessing a client who is receiving a continuous heparin infusion. Which of the following findings should the nurse report to the provider?

A. Platelet count of 200,000/mm³
B. aPTT of 50 seconds
C. Hemoglobin of 14 g/dL
D. INR of 1.0

Correct answer: D

Rationale: The correct answer is D because an INR of 1.0 is below the therapeutic range for clients receiving heparin, indicating a potential need for dosage adjustment. Platelet count (choice A) within normal range, aPTT (choice B) within therapeutic range, and hemoglobin level (choice C) are not directly related to the monitoring of heparin therapy and would not require immediate reporting to the provider.

3. 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.

4. What is the initial intervention for a patient experiencing an allergic reaction?

A. Administer antihistamines
B. Administer corticosteroids
C. Administer oxygen
D. Administer IV fluids

Correct answer: A

Rationale: The correct answer is to administer antihistamines as the initial intervention for a patient experiencing an allergic reaction. Antihistamines work to block the effects of histamine, a substance released during an allergic reaction, helping to relieve symptoms such as itching, swelling, and hives. Corticosteroids (Choice B) are sometimes used in severe cases to reduce inflammation, but they are not the first-line treatment for an allergic reaction. Administering oxygen (Choice C) may be necessary if the patient is having difficulty breathing, but it is not the first intervention. IV fluids (Choice D) are typically given for conditions like dehydration or shock, not as the primary intervention for an allergic reaction.

5. What is the best position for a patient in respiratory distress?

A. Semi-Fowler's position
B. Trendelenburg position
C. Prone position
D. Supine position

Correct answer: A

Rationale: The best position for a patient in respiratory distress is the Semi-Fowler's position. This position promotes lung expansion and eases breathing by allowing the chest to expand more fully. The Trendelenburg position (choice B) where the patient's feet are higher than the head is not recommended in respiratory distress as it may cause increased pressure on the chest and reduced lung expansion. The prone position (choice C) lying on the stomach is also not optimal for respiratory distress as it can further compromise breathing. The supine position (choice D) lying flat on the back is not ideal as it may impair breathing by restricting chest expansion.
