A nurse is teaching a group of assistive personnel about performing hand hygiene when caring for a client who has an immunodeficiency disorder. Which of the following information should the nurse include in the teaching?

Rationale: A. Decontaminate hands with an alcohol-based hand rub after taking the client's pulse: Alcohol-based hand rubs are effective for decontaminating hands after routine tasks like taking a pulse, provided hands are not visibly soiled. They are effective in removing most pathogens, making them ideal. B. Dry hands by starting from the wrist and moving toward the fingers: Hands should be dried by patting them gently with a clean paper towel, starting from the fingers and moving toward the wrist. This technique reduces the risk of transferring pathogens to clean areas. C. Wash hands with an alcohol-based hand rub if you have artificial nails: Alcohol-based hand rubs should not be used if artificial nails are present, as they may not effectively remove pathogens from under the nails. Handwashing with soap and water is preferred in these cases. D. Lather hands with soap and apply friction under running water for 5 seconds: Handwashing should involve lathering with soap for at least 20 seconds, not 5, to ensure that friction is applied across all areas of the hands to remove pathogens effectively.
