A nurse assesses an audible grating sound (crepitus) when a client with osteoarthritis moves his knees. What is the cause of this 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.

Choice A reason: This is not the best intervention because it is timeconsuming and may not be feasible in some situations. Writing down the message can also be impersonal and may not convey the tone or emotion of the speaker. The nurse should use verbal communication as much as possible and supplement it with nonverbal cues, such as gestures, facial expressions, and eye contact.

Choice B reason: This is an incorrect intervention because it can be annoying and ineffective. Talking loudly in the impaired ear can cause discomfort and distortion of the sound. It can also damage the remaining hearing in the ear. The nurse should not shout or raise their voice, but rather speak at a normal volume and enunciate clearly.

Choice C reason: This is the best intervention because it enhances the quality and clarity of the verbal message. Speaking slowly and clearly while facing the client allows the client to see the nurse's mouth movements and facial expressions, which can help them understand the words and the meaning. The nurse should also avoid covering their mouth or chewing gum while speaking.

Choice D reason: This is not the best intervention because it can be inconvenient and impractical. Talking in a regular voice in the good ear may require the nurse to move around the client or position themselves in a certain way. It can also make the client feel isolated or singled out. The nurse should try to communicate with the client in a way that is comfortable and respectful for both parties.
