A client does not understand why vision loss due to glaucoma is irreversible. What is the nurse's best explanation?

Choice A reason: Determine whether it is temporary or permanent is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Determining whether the compromised immunity is temporary or permanent is an important assessment, but it should be done after ensuring the safety and infection prevention of the client. Compromised immunity can be temporary or permanent, depending on the cause, such as medication, disease, or genetic disorder.

Choice B reason: Take the client's vital signs every four hours is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Taking the client's vital signs every four hours is an important monitoring, but it should be done after ensuring the safety and infection prevention of the client. Vital signs can indicate the general health status and the presence of infection or inflammation, such as fever, tachycardia, or hypotension.

Choice C reason: Teach the family members to receive the flu shot annually is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Teaching the family members to receive the flu shot annually is an important education, but it should be done after ensuring the safety and infection prevention of the client. The flu shot is a vaccine that can protect the family members and the client from influenza, which can be a serious and potentially fatal infection for people with compromised immunity.

Choice D reason: Wash hands before entering the client's room is the nurse's priority action for a client with compromised immunity, because it is the most urgent and relevant. Washing hands before entering the client's room is a basic and essential infection prevention measure, which can protect the client from exposure to pathogens that can cause infection. People with compromised immunity have a weakened or impaired immune system, which makes them more susceptible and vulnerable to infection.

Choice A reason: Properly disposing of contaminated equipment is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Contaminated equipment, such as gloves, gowns, masks, or needles, should be disposed of in designated containers or bags to prevent exposure or injury to others. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.

Choice B reason: Discarding used syringes into appropriate containers is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Used syringes, especially those that contain blood or body fluids, should be discarded into punctureresistant, leakproof, and labeled containers to prevent needlestick injuries or exposure to others. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.

Choice C reason: Changing soiled linens is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Soiled linens, especially those that contain blood or body fluids, should be changed and handled with gloves and minimal agitation to prevent contamination or aerosolization of pathogens. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.

Choice D reason: Performing hand hygiene is the most effective way to prevent the spread of pathogens during client care, because it reduces the number of microorganisms on the hands of the health care worker, which are the most common source and mode of transmission of infection. Hand hygiene should be performed before and after contact with the client, after contact with potentially infectious materials, after removing gloves, and before and after performing invasive procedures. Hand hygiene can be performed by washing with soap and water or using alcoholbased hand rubs.
