b. "Everyone who lives in the home will need medication."

The nurse should inform the guardian that everyone who lives in the home will need medication when reinforcing teaching about enterobiasis. Enterobiasis, also known as pinworm infection, is highly contagious, and it can easily spread from person to person within the household. Treating only the affected individual may not be sufficient to eliminate the infection completely, as other household members may also be infected or at risk of reinfection.

Explanation for the other options:

a. "One dose of medication is all that will be necessary." Enterobiasis is typically treated with a medication regimen that involves taking multiple doses over a period of time. This is to ensure that all stages of the pinworm life cycle are targeted and eradicated. A single dose is usually not sufficient to eliminate the infection completely.

c. "Allow the child to take tub baths instead of showers." The choice of tub baths or showers does not directly impact the treatment or prevention of enterobiasis. Both methods of bathing can be used, but it is important to maintain good hygiene practices, such as regular handwashing and proper cleaning of the perianal area, to reduce the risk of reinfection.

d. "Wash all clothes and bed linens in cold water." While proper hygiene practices and laundering of clothes and bed linens are important in preventing the spread of enterobiasis, using cold water alone may not be sufficient. Washing clothes and bed linens in hot water (at a temperature of at least 60°C or 140°F) is recommended to kill any pinworm eggs that may be present.

b. "You feel upset by the responses of others."

The appropriate response by the nurse is to acknowledge and validate the client's feelings. Option b, "You feel upset by the responses of others," demonstrates empathy and reflects back the client's feelings, indicating that the nurse understands and acknowledges the client's distress.

Explanation for the other options:

a. "I think you should just ignore the others." This response dismisses the client's concerns and does not address the underlying issue of the client feeling hurt by the interactions with others. It is important for the nurse to address the client's feelings and provide support.

c. "Let's keep the focus of our discussion on your needs." While it is important to address the client's needs, it is also necessary to address the client's concerns and feelings related to the interactions with other clients. Ignoring or dismissing the client's concerns can further isolate the client and hinder their progress in the therapeutic environment.

d. "Everything will get beter once you get to know everyone." This response minimizes the client's feelings and does not provide immediate support or address the client's concerns. It is essential for the nurse to validate the client's emotions and explore strategies to address the issue of others making fun of the client.

In summary, the nurse should choose a response that acknowledges the client's feelings and demonstrates empathy. Validating the client's experience can help establish trust and provide a foundation for further therapeutic interventions.
