What statement by the client indicates a correct understanding of the timing of progression of human immunodeficiency virus (HIV) to acquired immunodeficiency syndrome (AIDS)?

Choice A reason: This is the correct statement because it reflects the fact that reexposure to HIV can increase the viral load and accelerate the decline of the immune system. HIV is a virus that infects and destroys the CD4 cells, which are the white blood cells that help fight infections. AIDS is the final stage of HIV infection, when the CD4 count falls below 200 cells/mm3 or the client develops an opportunistic infection. The progression from HIV to AIDS can vary from person to person, depending on several factors, such as viral strain, genetic factors, treatment adherence, and coinfections. Reexposure to HIV can expose the client to a different or more aggressive strain of the virus, which can overwhelm the immune system and hasten the development of AIDS.

Choice B reason: This is an incorrect statement because it ignores the role of nutrition in maintaining the health and function of the immune system. Diet can influence the progression of HIV to AIDS by affecting the client's weight, energy, metabolism, and susceptibility to infections. The client should eat a balanced and varied diet that provides adequate calories, protein, vitamins, minerals, and fluids. The client should also avoid foods that can cause diarrhea, dehydration, or food poisoning, which can worsen the symptoms and complications of HIV infection.

Choice C reason: This is an incorrect statement because it contradicts the evidence that shows that meditation can have positive effects on the psychological and physiological wellbeing of people living with HIV. Meditation is a mindbody practice that involves focusing attention on the present moment, breathing, and relaxation. Meditation can help the client cope with stress, anxiety, depression, and pain, which are common challenges for people living with HIV. Meditation can also improve the immune system function by reducing inflammation, oxidative stress, and cortisol levels, which can slow down the progression of HIV to AIDS.

Choice D reason: This is an incorrect statement because it overlooks the impact of sexually transmitted infections (STIs) on the course of HIV infection. STIs can increase the risk of transmitting and acquiring HIV by causing ulcers, inflammation, or bleeding in the genital area, which can facilitate the entry and exit of the virus. STIs can also increase the viral load and decrease the CD4 count, which can speed up the progression of HIV to AIDS. The client should practice safe sex by using condoms, getting tested and treated for STIs, and informing their sexual partners about their HIV status.

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.
