A nurse is assessing a client's vital signs. The oxygen saturation is 85%. What intervention should the nurse perform first?

Choice A reason: Popping bursae from standing is not the cause of the grating sound. Bursae are fluidfilled sacs that cushion the joints and reduce friction. Popping bursae may produce a snapping or clicking sound, but not a grating sound.

Choice B reason: A herniated disk in the diseased joint is not the cause of the grating sound. A herniated disk is a condition where the soft inner part of the intervertebral disk bulges out through a tear in the outer layer. A herniated disk may cause pain, numbness, or weakness, but not a grating sound.

Choice C reason: Pieces of bone and cartilage floating is the cause of the grating sound. Osteoarthritis is a degenerative joint disease that causes the breakdown of the cartilage and bone in the joints. Pieces of bone and cartilage may detach and float in the joint space, causing a grating sound when the joint moves.

Choice D reason: Years of an autoimmune process is not the cause of the grating sound. An autoimmune process is a condition where the immune system attacks the body's own tissues. An autoimmune process may cause inflammation, swelling, or damage to the joints, but not a grating sound.

Choice A reason: This is the best intervention because it helps the nurse to understand the client's emotional, social, and practical needs and resources. A new diagnosis of HIV can be a devastating and overwhelming experience for the client, who may face stigma, discrimination, isolation, or rejection from others. The nurse should assess the client's support system, such as family, friends, or community groups, that can provide comfort, guidance, and assistance to the client. The nurse should also encourage the client to seek professional counseling, peer support, or other services as needed.

Choice B reason: This is not the best intervention because it may not respect the client's preferences, beliefs, or values. The nurse should not assume that the client wants or needs spiritual or religious support, unless the client expresses such a desire. The nurse should ask the client about their spiritual or religious beliefs and practices and provide appropriate referrals or resources as requested by the client. The nurse should also respect the client's right to privacy and confidentiality and not disclose the client's diagnosis to anyone without the client's consent.

Choice C reason: This is not the best intervention because it may not be the most urgent or appropriate topic to discuss with the client at this time. The nurse should not focus on the legal or ethical aspects of the client's diagnosis, but rather on the client's emotional and physical wellbeing. The nurse should explain the legal requirement to tell sex partners in a sensitive and respectful manner, but only after the client has accepted and understood their diagnosis and has expressed readiness to disclose their status to others. The nurse should also provide the client with information and resources on how to prevent the transmission of HIV and how to protect themselves and their partners.

Choice D reason: This is not the best intervention because it may not be the client's wish or choice. The nurse should not offer to tell the family for the client, unless the client asks for such help. The nurse should respect the client's autonomy and decisionmaking regarding whom to tell and when to tell about their diagnosis. The nurse should also support the client in preparing for the possible reactions and outcomes of disclosing their status to their family and others.
