Correct Answer is A

Explanation

Choice A rationale: If the client's skin becomes red, the heat application should be stopped to prevent burns or skin damage.
Choice B rationale: Heat applications are generally recommended for 20-30 minutes, not at least 40 minutes, to avoid skin damage.
Choice C rationale: Safety pins should not be used to keep the heating pad in place, as they can damage the pad or cause injury to the client.
Choice D rationale: The temperature of the heating pad should be set to a comfortable and safe level, typically below 42.2° C (108° F).

A. "I should use my axilla to bear body weight." B. "I should keep my elbows extended." C. "When getting up out of the chair, I should extend my uninjured leg." D. "To climb stairs, I should place weight on my unaffected leg first."

Correct Answer is D

Explanation

Choice A rationale: Using the axilla to bear body weight can lead to nerve damage and is not a proper crutch technique.
Choice B rationale: Keeping the elbows extended can lead to discomfort and poor crutch control. The elbows should be slightly flexed.
Choice C rationale: When getting up from a chair, extending the uninjured leg first is not the correct technique. The patient should keep the injured leg extended for stability.
Choice D rationale: Placing weight on the unaffected leg first when climbing stairs is the correct technique, allowing for better balance and stability.
