An infection control nurse is teaching a class about transmission of infectious agents. The nurse should include that which of the following diseases is transmitted via airborne transmission?

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.

A. This response acknowledges the parent's concern but maintains confidentiality regarding the report. It offers to involve the supervisor, which is a reasonable step. However, it may leave the parent feeling uneasy or uncertain.
B. This response directly informs the parent about the legal obligation of the nurse to report suspected child abuse. It provides clarity on why the nurse took action. However, it might be perceived as abrupt or lacking empathy.
C. This response suggests that someone else (possibly a healthcare provider or another authority figure) will explain the situation later. It doesn't directly address the reason for the nurse's action or the legal requirement to report.
D. This response explains the chain of events, from reporting to the supervisor's decision to contact authorities. It provides information but might not directly address the parent's emotional concern or the legal obligation of the nurse.
