Which client is at the greatest risk for pressure injury development?

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: Stage 1 is a wound that involves only the epidermis, the outermost layer of the skin. It appears as a nonblanchable redness, warmth, or hardness on intact skin. It does not have any breakage or ulceration of the skin.

Choice B reason: Stage 2 is a wound that involves the epidermis and the dermis, the second layer of the skin. It appears as a shallow, open, reddened ulcer with a partialthickness loss of skin. It may have some serous exudate, but no slough or eschar. It may also present as a blister or abrasion.

Choice C reason: Stage 3 is a wound that involves the epidermis, the dermis, and the subcutaneous tissue, the third layer of the skin. It appears as a deep, open, reddened ulcer with a fullthickness loss of skin. It may have some slough or eschar, but no exposed bone, tendon, or muscle. It may also have tunneling or undermining of the wound edges.

Choice D reason: Stage 4 is a wound that involves the epidermis, the dermis, the subcutaneous tissue, and the underlying structures, such as bone, tendon, or muscle. It appears as a deep, open, reddened ulcer with a fullthickness loss of skin and tissue. It has exposed bone, tendon, or muscle, which may be visible or palpable. It may also have slough, eschar, necrosis, infection, or osteomyelitis.
