• A. Increased high density lipoprotein
• B. Increased circulation
• C. Increased pumping action of the heart

3. 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.

4. 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.

• 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.
