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. A client who is sitting in High-Fowler's position is at risk for what type of injury as the skin layers shift in opposite directions?

D. Shearing injury

Correct answer: D

Rationale:

3. What may be a cause of conductive hearing loss?

A. Prolonged exposure to loud noises
B. Medications
C. Presbycusis
D. Otitis media

Correct answer: D

Rationale: Otitis media can cause conductive hearing loss by affecting the middle ear.

4. Why is a client with osteoporosis prone to fractures?

A. The client has bone spurs that lead to fractures
B. The client has increased bone density
C. The client has porous bones
D. The client is not prone to fractures

Correct answer: C

Rationale: The correct answer is C. Osteoporosis is characterized by porous, weak bones due to decreased bone density. This porous nature of bones in osteoporosis makes them more prone to fractures. Choice A is incorrect because bone spurs do not lead to fractures in osteoporosis; they are bony outgrowths unrelated to osteoporosis. Choice B is incorrect as osteoporosis is associated with decreased, not increased, bone density. Choice D is incorrect as individuals with osteoporosis are indeed prone to fractures due to weakened bones.
