A nurse is caring for a client who is receiving heat applications using a heating pad. Which of the following actions should the nurse take when applying the pad?

Choice A rationale: Bearing the weight of the body on the hands is not the correct technique for using crutches. The weight should be borne on the arms, not the hands.
Choice B rationale: Using crutches that belonged to someone else may not be appropriate as they need to be properly fitted for the individual. Additionally, old crutches may be worn or damaged.
Choice C rationale: This statement is appropriate and does not indicate a need for additional teaching. Keeping spare crutch tips is a good practice, as crutch tips can wear down over time and may need replacement. This demonstrates the client's understanding of the need for maintenance and preparedness.
Choice D rationale: This statement is appropriate and indicates a good understanding of crutch care. Regular inspection of crutches is important to ensure their safety and effectiveness. It allows the client to identify any signs of wear or damage early on and take necessary actions, such as replacing worn-out parts, to prevent accidents or injuries.

Choice A rationale: The skin helps regulate body temperature by sweating and dilation or constriction of blood vessels.
Choice B rationale: The skin acts as a barrier, protecting the body from external threats such as pathogens and physical injury.
Choice C rationale: The skin is rich in sensory receptors, allowing for the perception of touch, pressure, pain, and temperature.
Choice D rationale: The skin plays a role in the production of vitamin D when exposed to sunlight.
Choice E rationale: Vitamin C production is not a function of the skin; vitamin C is obtained through diet.
