A home health nurse is assessing an older adult client in the home who has decreased vision due to a history of glaucoma. Which of the following findings should the nurse identify as a safety risk?
- A. Scatter rugs are present in the kitchen,
- B. Handrails are present in the bathroom.
- C. Electrical cords are placed along the walls.
- D. Uses a microwave for cooking.
Correct Answer: A
Rationale: Scatter rugs can cause tripping and slipping, posing a significant fall risk for someone with vision impairment.

A microwave is generally safer than a stove, reducing the risk of burns and fires.
