A man has been admitted to the hospital unit with a medical diagnosis of chronic obstructive pulmonary disease (COPD). He is receiving supplemental oxygen at 2 L/min via a nasal cannula. Which positioning technique will best assist him with breathing?

Choice A reason: These drugs kill the virus is not true about antiretroviral drugs used to treat human immunodeficiency virus (HIV), because it is inaccurate and misleading. Antiretroviral drugs do not kill the virus, but rather block or interfere with the enzymes or proteins that the virus needs to replicate or integrate into the host cells. Antiretroviral drugs can reduce the viral load, which is the amount of virus in the blood, but they cannot eliminate the virus completely.

Choice B reason: Only certain licensed drugs are effective is not true about antiretroviral drugs used to treat human immunodeficiency virus (HIV), because it is vague and incomplete. Antiretroviral drugs are licensed and approved by the regulatory authorities, such as the Food and Drug Administration (FDA), based on their safety and efficacy. However, not all licensed drugs are equally effective for all people with HIV, as the virus can develop resistance or mutation to some drugs over time. Therefore, the choice and combination of antiretroviral drugs may vary depending on the individual's viral genotype, drug history, and drug interactions.

Choice C reason: A few missed doses per month are OK is not true about antiretroviral drugs used to treat human immunodeficiency virus (HIV), because it is incorrect and dangerous. Antiretroviral drugs require strict adherence and compliance, which means taking the drugs exactly as prescribed, without missing or skipping any doses. A few missed doses per month are not OK, as they can reduce the effectiveness of the drugs and increase the risk of viral resistance or mutation, which can lead to treatment failure or disease progression.

Choice D reason: These drugs inhibit viral replication is true about antiretroviral drugs used to treat human immunodeficiency virus (HIV), because it describes the mechanism and outcome of the drugs. Antiretroviral drugs inhibit viral replication, which means they prevent or slow down the multiplication or reproduction of the virus. Antiretroviral drugs can inhibit viral replication by targeting different stages of the viral life cycle, such as reverse transcription, integration, or maturation. Antiretroviral drugs can improve the immune function and quality of life of people with HIV.

Choice A reason: Washing your hands thoroughly is an important measure to reduce the risk of infection. Hand washing is one of the most effective ways to prevent the transmission of germs that can cause diseases. Hand washing can remove dirt, bacteria, viruses, and other contaminants from the skin and prevent them from entering the body or spreading to others. The nurse should teach the client with AIDS to wash their hands frequently and properly, especially before and after eating, using the bathroom, touching their face, or handling any objects that may be contaminated.

Choice B reason: Avoiding cleaning your toothbrush with bleach is not a measure to reduce the risk of infection. Cleaning your toothbrush with bleach is not a recommended practice, as bleach is a harsh chemical that can damage the toothbrush and irritate the mouth. However, cleaning your toothbrush with bleach does not increase the risk of infection, as bleach can kill most germs that may be present on the toothbrush. The nurse should teach the client with AIDS to rinse their toothbrush with water after each use and replace it every 3 to 4 months or sooner if the bristles are worn or frayed.

Choice C reason: Avoiding raw fruits and vegetables is a measure to reduce the risk of infection. Raw fruits and vegetables may be contaminated with bacteria, parasites, or pesticides that can cause foodborne illnesses. The client with AIDS has a weakened immune system that cannot fight off these infections effectively and may develop serious complications, such as diarrhea, dehydration, or malnutrition. The nurse should teach the client with AIDS to wash, peel, or cook their fruits and vegetables before eating them and to avoid any that are bruised, moldy, or spoiled.

Choice D reason: Avoiding crowds is a measure to reduce the risk of infection. Crowds are places where many people gather and interact, such as public transportation, shopping malls, schools, or workplaces. Crowds increase the exposure to germs that can cause respiratory, gastrointestinal, or skin infections. The client with AIDS has a lowered resistance to these infections and may contract them more easily and severely. The nurse should teach the client with AIDS to avoid crowds as much as possible and to wear a mask, practice social distancing, and use hand sanitizer if they have to be in a crowded place.

Choice E reason: Not sharing toothpaste with family members is a measure to reduce the risk of infection. Sharing toothpaste with family members can transfer saliva, blood, or other body fluids that may contain germs that can cause oral, dental, or systemic infections. The client with AIDS is more susceptible to these infections and may also transmit the HIV virus to their family members through their body fluids. The nurse should teach the client with AIDS to use their own toothpaste and toothbrush and to store them separately from their family members' ones.
