Answer to Question 1

D
The brain stem serves as a conduction pathway between the higher and lower neural centers. Reticular formation runs through the brain stem and plays a role in arousal. Respiratory and cardiac regulation is done by the brain stem. The brain stem does not help control motor functions.

Answer to Question 2

3. Do not smoke.

Rationale:
The one modifiable risk factor for hip fractures is smoking. Women who smoke have a greater risk because smoking reduces bone density in menopausal and postmenopausal women. The client should not be instructed to avoid exercise; exercise will enhance the client's gait, balance, and musculoskeletal strength. Limiting sun exposure will not impact the client's risk of experiencing a hip fracture. The nurse should not instruct the client to use throw rugs throughout the home because this could cause tripping, leading to a fall.
