A nurse is providing oral hygiene for an unconscious client. What is the priority nursing intervention?

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: Wearing a gown is the correct answer, because it is the appropriate PPE for contact precautions, which are required for clients who have MRSA. MRSA is a type of bacteria that is resistant to many antibiotics and can cause serious infections in the skin, blood, lungs, or other organs. MRSA can be transmitted by direct or indirect contact with the infected wound or contaminated surfaces. Wearing a gown can protect the nurse's clothing and skin from exposure to MRSA.

Choice B reason: Wearing sterile gloves is not the correct answer, because it is not the appropriate PPE for contact precautions, which are required for clients who have MRSA. Sterile gloves are used for sterile procedures, such as inserting a catheter or changing a dressing, not for routine assessments, such as checking the pulse. Wearing sterile gloves can be wasteful and unnecessary, and it does not provide adequate protection from MRSA.

Choice C reason: Wearing a PAPR mask is not the correct answer, because it is not the appropriate PPE for contact precautions, which are required for clients who have MRSA. PAPR stands for powered airpurifying respirator, and it is a type of mask that filters the air and provides positive pressure to the wearer. PAPR masks are used for airborne precautions, which are required for clients who have diseases that can be spread through the air, such as tuberculosis or measles, not for clients who have MRSA.

Choice D reason: Wearing a surgical mask is not the correct answer, because it is not the appropriate PPE for contact precautions, which are required for clients who have MRSA. Surgical masks are used for droplet precautions, which are required for clients who have diseases that can be spread through respiratory droplets, such as influenza or pertussis, not for clients who have MRSA.
