What is the priority intervention for the nurse to enhance meeting the psychosocial needs of a client on transmissionbased precautions?

Choice A reason: Once the tissue has necrosed from high pressure, it does not regenerate is the best explanation, because it describes the mechanism and outcome of glaucoma. Glaucoma is a condition that causes increased intraocular pressure, which damages the optic nerve and the retina, the tissues that are responsible for transmitting and processing visual information. Once these tissues are necrosed, or dead, they do not regenerate, or grow back, resulting in irreversible vision loss.

Choice B reason: Glaucoma always leads to permanent blindness is not a good explanation, because it is inaccurate and pessimistic. Glaucoma does not always lead to permanent blindness, but rather to progressive vision loss that can be prevented or slowed down with early diagnosis and treatment. Glaucoma can cause peripheral vision loss, tunnel vision, or blind spots, but not necessarily complete blindness.

Choice C reason: Once retinal detachment occurs, it does not return to its normal state is not a good explanation, because it is irrelevant and misleading. Retinal detachment is a condition that occurs when the retina separates from the underlying layer of blood vessels, which can cause vision loss or blindness. However, retinal detachment is not caused by glaucoma, nor is it a common complication of glaucoma. Retinal detachment can sometimes be repaired with surgery, depending on the extent and duration of the detachment.

Choice D reason: Once bacterial infection has caused damage, the tissue does not regenerate is not a good explanation, because it is incorrect and confusing. Bacterial infection is not a cause or a consequence of glaucoma, but rather a separate condition that can affect the eye. Bacterial infection can cause inflammation, pain, discharge, or redness in the eye, but not necessarily vision loss or tissue necrosis. Bacterial infection can usually be treated with antibiotics, which can prevent or reverse the damage.

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.
