A nurse is working with a community health care team to devise strategies for preventing violence in the community. Which of the following interventions is an example of tertiary prevention?

Choice A reason: Koplik spots are small, white, bluish-gray spots that appear on the inner cheeks, gums, or roof of the mouth before the rash develops. They are a characteristic sign of measles and can help to distinguish it from other viral infections.

Choice B reason: Persistent low-grade temperature is not a finding that the nurse should expect in a client who has measles. Measles typically causes a high fever that can reach up to 40°C (104°F) and lasts for four to seven days. The fever may spike when the rash appears and subside when the rash fades.

Choice C reason: Muscle aches and tenderness are not findings that the nurse should expect in a client who has measles. Measles mainly affects the respiratory system and the skin, and does not cause significant muscle involvement. The client may experience fatigue, weakness, or malaise, but not muscle pain or soreness.

Choice D reason: Rash confined to the trunk of the body is not a finding that the nurse should expect in a client who has measles. Measles causes a red, blotchy rash that usually starts on the face and spreads to the rest of the body, including the arms, legs, and feet. The rash may last for up to a week and may cause itching or peeling of the skin.

Choice A reason: Asking the client if they have been thinking about harming themselves is not the best response, as it may sound accusatory or judgmental. It may also make the client defensive or reluctant to share their feelings. The nurse should assess the client's suicide risk later, after establishing rapport and trust.

Choice B reason: Asking the client how long they have been feeling this way is not the most appropriate response, as it may imply that the nurse is more interested in the duration of the problem than the client's current situation. It may also suggest that the nurse expects the client to have a clear timeline of their feelings, which may not be the case.

Choice C reason: Telling the client to share what is going on with them right now is the best response, as it shows empathy and genuine interest in the client's perspective. It also invites the client to express their thoughts and emotions, and helps the nurse identify the factors that contribute to the client's sense of meaninglessness.

Choice D reason: Asking the client if they really think their life has no purpose is not a helpful response, as it may sound dismissive or sarcastic. It may also make the client feel invalidated or misunderstood, and reinforce their negative beliefs. The nurse should avoid challenging the client's statements, and instead explore the reasons behind them.
