A nurse enters the hospital room of a client with reduced immunity. What observation requires further action by the nurse?

Choice A reason: A client with leukemia is a susceptible host most at risk for infection. Leukemia is a type of cancer that affects the blood cells, especially the white blood cells, which are responsible for fighting infections. Leukemia causes the production of abnormal and immature white blood cells that cannot function properly and crowd out the normal ones. This leads to a condition called leukopenia, which is a low level of white blood cells. Leukopenia makes the client more vulnerable to infection by reducing the immune system's ability to defend against pathogens.

Choice B reason: A child who is immunized is not a susceptible host most at risk for infection. Immunization is a process that stimulates the immune system to produce antibodies against a specific disease. Immunization protects the child from getting infected by the disease or reduces the severity of the infection if it occurs. Immunization also prevents the spread of the disease to other people who are not immunized or who are immunocompromised.

Choice C reason: A 60yearold client is not a susceptible host most at risk for infection. Age is a factor that may influence the susceptibility to infection, but it is not the most important one. Older adults may have a weaker immune system due to aging, chronic diseases, or medications, but they may also have a stronger immune memory due to previous exposure to pathogens. The risk of infection in older adults depends on their overall health status, lifestyle, and preventive measures.

Choice D reason: A hospitalized 35yearold client is not a susceptible host most at risk for infection. Hospitalization is a factor that may increase the exposure to infection, but it is not the most significant one. Hospitalized clients may encounter various sources of infection, such as health care workers, other clients, medical equipment, or invasive procedures, but they may also receive adequate infection control measures, such as hand hygiene, isolation, sterilization, or prophylaxis. The risk of infection in hospitalized clients depends on their diagnosis, treatment, and compliance.

Choice A reason: Providing active range of motion (ROM) is not a treatment that the nurse can perform for a quadriplegic client. Active ROM means that the client moves their own joints without assistance. A quadriplegic client has paralysis of all four limbs and cannot move their joints voluntarily.

Choice B reason: Providing passive range of motion (ROM) is a treatment that the nurse can perform for a quadriplegic client. Passive ROM means that the nurse moves the client's joints through their full range of motion without resistance. This helps prevent joint contracture, which is the loss of joint movement and flexibility due to muscle shortening and stiffness. It also helps maintain joint mobility, which is the ability of the joint to move smoothly and freely.

Choice C reason: Turning the client every 2 hours is not a treatment that the nurse can perform to decrease the risk of joint contracture and promote joint mobility. Turning the client every 2 hours is a preventive measure to avoid pressure ulcers, which are skin injuries caused by prolonged pressure on the skin. It does not directly affect the joint function or movement.

Choice D reason: Administering glucosamine supplements is not a treatment that the nurse can perform to decrease the risk of joint contracture and promote joint mobility. Glucosamine supplements are dietary supplements that may help reduce the pain and inflammation of osteoarthritis, which is a degenerative joint disease that causes the breakdown of the cartilage and bone in the joints. It does not affect the muscle or nerve function or movement.
