Which practice is recommended to prevent human immune deficiency virus (HIV) transmission?

Choice A reason: Properly disposing of contaminated equipment is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Contaminated equipment, such as gloves, gowns, masks, or needles, should be disposed of in designated containers or bags to prevent exposure or injury to others. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.

Choice B reason: Discarding used syringes into appropriate containers is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Used syringes, especially those that contain blood or body fluids, should be discarded into punctureresistant, leakproof, and labeled containers to prevent needlestick injuries or exposure to others. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.

Choice C reason: Changing soiled linens is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Soiled linens, especially those that contain blood or body fluids, should be changed and handled with gloves and minimal agitation to prevent contamination or aerosolization of pathogens. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.

Choice D reason: Performing hand hygiene is the most effective way to prevent the spread of pathogens during client care, because it reduces the number of microorganisms on the hands of the health care worker, which are the most common source and mode of transmission of infection. Hand hygiene should be performed before and after contact with the client, after contact with potentially infectious materials, after removing gloves, and before and after performing invasive procedures. Hand hygiene can be performed by washing with soap and water or using alcoholbased hand rubs.

Choice A reason: This is not the correct answer because opioids are a class of medications that act on the opioid receptors in the brain and spinal cord to reduce pain perception and emotional response. Opioids do not have a direct effect on tissue inflammation or bone healing, but they can cause side effects such as constipation, nausea, sedation, respiratory depression, and addiction.

Choice B reason: This is not the correct answer because anticoagulants are a class of medications that prevent or reduce the formation of blood clots by interfering with the clotting factors or platelets. Anticoagulants do not have a direct effect on tissue inflammation or bone healing, but they can increase the risk of bleeding and hematoma formation, which can impair the blood supply and oxygen delivery to the injured tissues.

Choice C reason: This is the correct answer because NSAIDs are a class of medications that inhibit the enzyme cyclooxygenase (COX), which is involved in the synthesis of prostaglandins, which are inflammatory mediators that cause pain, swelling, and fever. NSAIDs can decrease tissue inflammation and pain, but they can also delay bone healing by reducing the formation of osteoblasts, which are cells that build new bone tissue.

Choice D reason: This is not the correct answer because narcotics are another term for opioids, which are a class of medications that act on the opioid receptors in the brain and spinal cord to reduce pain perception and emotional response. Narcotics do not have a direct effect on tissue inflammation or bone healing, but they can cause side effects such as constipation, nausea, sedation, respiratory depression, and addiction.
