The nurse applies a warmed blanket to a chilled patient. Which term is used to describe the process by which the blanket increases the patient’s temperature?

Choice A reason: This is an incorrect choice because gently trimming the patient’s toenails after soaking the feet in warm soapy water is not the best intervention of the nurse for a diabetic patient who has rough skin on the feet and thick, overgrown toenails. Trimming the toenails can be risky for the diabetic patient, as it can cause bleeding, infection, or injury to the nail bed or surrounding skin. The nurse should avoid cutting the toenails of the diabetic patient, unless instructed by a podiatrist.

Choice B reason: This is an incorrect choice because using a pumice stone to smooth roughened areas of skin on the patient’s feet is not the best intervention of the nurse for a diabetic patient who has rough skin on the feet and thick, overgrown toenails. A pumice stone is a porous rock that can be used to exfoliate the skin and remove dead cells. However, it can also damage the skin and cause abrasions, irritation, or infection. The nurse should be careful when using a pumice stone on the diabetic patient, and avoid rubbing too hard or too often.

Choice C reason: This is an incorrect choice because liberally applying lotion to the patient's feet especially between the toes is not the best intervention of the nurse for a diabetic patient who has rough skin on the feet and thick, overgrown toenails. Applying lotion to the feet can help to moisturize and soften the skin, but it can also create a moist environment that can promote fungal growth and infection. The nurse should apply lotion sparingly to the feet of the diabetic patient, and avoid applying it between the toes.

Choice D reason: This is the correct choice because obtaining a consultation for a podiatrist to assess the feet and provide nail care is the best intervention of the nurse for a diabetic patient who has rough skin on the feet and thick, overgrown toenails. A podiatrist is a specialist who can diagnose and treat foot problems, such as nail disorders, skin conditions, or infections. The podiatrist can safely and effectively trim the toenails of the diabetic patient, and provide education and advice on foot care and prevention of complications. The nurse should refer the diabetic patient to a podiatrist at least once a year, or more often if needed.

Choice A reason: This is incorrect. Wiping up the liquid with paper towels and gloves can spread the mercury droplets and increase the risk of exposure. Mercury can also penetrate through nitrile gloves and cause skin irritation.

Choice B reason: This is incorrect. Disinfecting the area with chlorine bleach can create toxic vapours that can harm the respiratory system. Chlorine bleach is not effective in removing mercury from the surface.

Choice C reason: This is incorrect. Contacting the housekeeping staff to mop up the liquid can delay the proper clean-up and disposal of mercury. Mopping can also disperse the mercury droplets and contaminate the mop and the water.

Choice D reason: This is correct. Consulting the agency’s materials safety data sheets (MSDS) is the priority action of the nurse. MSDS provide information on the hazards, precautions, and procedures for handling and disposing of mercury. The nurse should follow the MSDS guidelines and use the appropriate equipment and methods to clean up the spill.
