Which of the following instruction should a nurse provide to promote the safe use of a cane as an assistive device for a client who is recovering from a musculoskeletal injury of the right lower extremity?
Hold the cane on the left side.
Place the cane 46 cm (18 in) in front of her feet before advancing.
Adjust the height of the cane so the arm is straight during use.
Remove the rubber tip from the end of the cane.
The Correct Answer is A
A. Hold the cane on the left side: The cane should be held on the stronger (unaffected) side (in this case, the left) to provide balance and support for the injured right leg.
B. Place the cane 46 cm (18 in) in front of her feet before advancing: The cane should only be placed about 15–25 cm (6–10 in) in front to maintain stability.
C. Adjust the height of the cane so the arm is straight during use: The elbow should be slightly flexed (~20–30 degrees) for optimal balance and comfort.
D. Remove the rubber tip from the end of the cane: The rubber tip is essential for traction and to prevent slipping.

Correct Answer is C
Explanation
A. "I will place an area rug at the entry of my bathroom.": Area rugs are fall hazards and should be removed.
B. "I will keep the fluorescent ceiling light on in my room at night.": While keeping lights on is helpful, ceiling lights may be too bright or not easily accessible. A night light or bedside lamp is safer and more practical.
C. “I will place a bath seat in my shower to use when I bathe.": Using a bath seat reduces the risk of slipping and falling in the shower.
D. “I will keep my walker at the end of my bed.": The walker should be kept within reach to ensure it is easily accessible when the client gets out of bed.
Correct Answer is A
Explanation
A. Warm the affected area in a water bath: The affected area should be rewarmed gradually using a water bath at 37° to 39°C (98.6° to 102.2°F) to minimize tissue damage.
B. Administer the pneumococcal vaccine: This is not related to the immediate treatment of frostbite.
C. Massage the calf and thigh muscles: Massaging frostbitten areas can cause further tissue injury and is contraindicated.
