A nurse is providing teaching to a client who has a prescription for heat therapy for treatment of cellulitis of the right lower leg. Which of the following client statements indicates an understanding of the teaching?
"I'll keep a heating pad on the calf of my right leg when I am lying down."
"I'll wrap a warm, wet towel around my right calf every 4 hours."
"I'll place my leg under a heat lamp every 3 hours."
"I will sit on the side of the tub and soak my right leg two times every day."
The Correct Answer is B
Rationale:
A. Keeping a heating pad on the leg for extended periods can lead to burns or skin damage. Heat therapy should be applied intermittently with breaks to prevent overheating.
B. Wrapping a warm, wet towel and applying it intermittently is appropriate for localized heat therapy and can help reduce inflammation and promote healing.
C. Using a heat lamp may not provide consistent or controlled heat application and is not the standard approach for treating cellulitis.
D. Soaking the leg in a tub is not recommended as it may introduce bacteria and potentially worsen the infection.

Correct Answer is D
Explanation
Rationale:
A. Action involves actively making changes or implementing strategies to alter behavior. The client's refusal to follow dietary advice indicates they are not actively engaging in behavior change.
B. Preparation entails planning and getting ready to make a change. The client’s statement shows no intention of preparing for a change.
C. Contemplation involves recognizing the need for change and considering it but not yet committed to making it. The client’s dismissive attitude suggests they are not at this stage.
D. Precontemplation is characterized by a lack of awareness or denial of the need for change. The client’s indifference to the dietary recommendations reflects this stage, as they are not yet considering changing their behavior.
