A charge nurse is teaching a group of staff members about hand hygiene. Which of the following information should the nurse include in the teaching?

A. The water temperature for handwashing should be comfortable and tolerable for the hands. Hot water can be drying to the skin and may not necessarily improve the effectiveness of hand hygiene. Ideally, the water temperature should be warm, but not uncomfortably hot or cold, to encourage thorough handwashing.
B. The amount of soap used for handwashing is important for effective cleaning. Applying 4 to 5 mL (approximately a teaspoon) of liquid soap ensures adequate coverage to create lather and effectively cleanse the hands. Too little soap may not produce enough lather to clean effectively, while too much may be wasteful.
C. During hand hygiene, it's recommended to keep the hands lower than the elbows to prevent water from running from the contaminated area (hands) to the cleaner area (elbows). This helps maintain hygiene and prevents potential contamination of the cleaned hands.
D. After washing hands with soap and water, it's important to dry them thoroughly. However, rubbing hands and arms to dry is not recommended. Instead, hands should be dried using a clean towel or paper towel. Rubbing can cause friction and potential irritation to the skin.

A. Immunosuppressant medications are drugs that suppress or weaken the immune system. They are often prescribed to prevent rejection of transplanted organs or to treat autoimmune diseases. However, a weakened immune system makes individuals more susceptible to infections because their body's ability to fight off pathogens is compromised. Therefore, clients taking immunosuppressant medications have an increased risk of contracting communicable diseases.
B. Poor nutrition can weaken the immune system, making it less effective in defending against infections. Essential nutrients such as vitamins and minerals play crucial roles in immune function. A deficiency in these nutrients can impair immune responses, making individuals more vulnerable to communicable diseases.
C. Keeping immunizations up to date helps protect individuals from specific communicable diseases for which vaccines are available. Vaccines stimulate the immune system to produce antibodies against particular pathogens, providing immunity. Therefore, if immunizations are up to date, the client's risk of contracting certain communicable diseases is reduced.
D. Aging is associated with changes in the immune system, known as immunosenescence, which can weaken immune responses. Older adults may have decreased production of immune cells and antibodies, making them more susceptible to infections. Additionally, aging is often accompanied by chronic health conditions or medications that further compromise immune function, increasing the risk of communicable diseases.
E. Living in a nursing home or long-term care facility can increase the risk of exposure to communicable diseases due to close contact with other residents, sharing of common spaces, and potentially inadequate infection control practices. Older adults in nursing homes may also have multiple chronic conditions and weakened immune systems, further increasing their susceptibility to infections.
