1. Death of bone tissue can occur when the blood supply to the bone is disrupted. What is this complication called?

• A. Reflex sympathetic dystrophy
• B. Avascular necrosis
• C. Delayed union
• D. Complex regional pain syndrome

Correct Answer: B

Rationale: The correct answer is B, avascular necrosis. Avascular necrosis is the condition where bone tissue dies due to the disruption of blood supply to the bone. Reflex sympathetic dystrophy (Choice A) is a chronic pain condition, delayed union (Choice C) refers to a delayed healing of a fracture, and complex regional pain syndrome (Choice D) is a chronic pain condition typically affecting an arm or leg.

2. Which test is used in the diagnosis of osteoporosis?

• A. Phalen's maneuver
• B. Dual-energy X-ray absorptiometry (DXA) scan
• C. Proprioception
• D. Blood culture

Correct Answer: B

Rationale: The correct answer is B, Dual-energy X-ray absorptiometry (DXA) scan, which is commonly used to diagnose osteoporosis by measuring bone mineral density. Phalen's maneuver (choice A) is a test used to assess for carpal tunnel syndrome and is not related to osteoporosis. Proprioception (choice C) refers to the sense of body position and is not a diagnostic test for osteoporosis. Blood culture (choice D) is used to detect infections caused by bacteria in the bloodstream and is not relevant to the diagnosis of osteoporosis.

3. What is one of the earliest signs of fat embolism syndrome?

• A. Paresthesia
• B. Severe pain in the affected limb unrelieved by medication
• C. Edema
• D. Hypoxemia

Correct Answer: D

Rationale: Hypoxemia is one of the earliest signs of fat embolism syndrome. In fat embolism syndrome, fat globules enter the bloodstream and can obstruct blood flow in the lungs, leading to hypoxemia. Paresthesia, severe pain unrelieved by medication, and edema are not typically among the earliest signs of fat embolism syndrome.

4. The nurse uses proper body mechanics to move a client up in bed. What action by the nurse will increase their risk of a workplace injury?

• A. Place the bed in the lowest possible position
• B. Use the legs when lifting
• C. Keep feet apart to provide a wide base of support
• D. Face the direction of the movement

Correct Answer: A

Rationale: Placing the bed in the lowest possible position increases the risk of injury because it does not support proper body mechanics. When lifting a client, it is important to have the bed at a comfortable height to avoid strain. Using the legs when lifting (choice B) is correct as it reduces the strain on the back. Keeping feet apart to provide a wide base of support (choice C) helps with stability and balance. Facing the direction of the movement (choice D) is essential for maintaining proper alignment and reducing the risk of injury.

5. What intervention by the nurse would be the best to prevent deep vein thrombosis after a fracture of the hip?

• A. Encouraging bedrest
• B. Applying antiembolism stockings
• C. Tell the client to take anticoagulants
• D. Teaching about smoking cessation

Correct Answer: B

Rationale: The best intervention to prevent deep vein thrombosis (DVT) after a fracture of the hip is to apply antiembolism stockings. These stockings help promote circulation and prevent blood clots from forming in the legs due to immobility. Encouraging bedrest is not recommended as it can increase the risk of DVT. While anticoagulants are used in some cases, the primary prevention method is mechanical prophylaxis like antiembolism stockings. Teaching about smoking cessation is important for overall health but is not directly related to preventing DVT in this scenario.
