A nurse is caring for a 25yearold male quadriplegic client. Which of the following treatments would the nurse perform to decrease the risk of joint contracture and promote joint mobility?

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: Eradicating the disease is not the purpose of the medications, because osteoarthritis is a chronic and progressive condition that cannot be cured by drugs. Osteoarthritis is a degenerative joint disease that causes the breakdown of cartilage and bone, leading to pain, stiffness, and reduced mobility.

Choice B reason: Turning on the immune system is not the purpose of the medications, because osteoarthritis is not an autoimmune disease that involves the immune system attacking the joints. Osteoarthritis is a mechanical disease that involves the wear and tear of the joints due to aging, injury, or overuse.

Choice C reason: Reducing pain and inflammation is the purpose of the medications, because osteoarthritis is a painful and inflammatory condition that affects the quality of life of the client. The medications for osteoarthritis include analgesics, such as acetaminophen or opioids, and antiinflammatory drugs, such as nonsteroidal antiinflammatory drugs (NSAIDs) or corticosteroids, which can relieve the symptoms and improve the function of the joints.

Choice D reason: Managing weight loss is not the purpose of the medications, because osteoarthritis is not a metabolic disease that affects the weight of the client. Osteoarthritis is a structural disease that affects the joints of the client. However, managing weight is an important factor in preventing or treating osteoarthritis, as excess weight can increase the stress and damage on the joints.
