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.

Answer: D. "Clean the prosthesis using a damp, soapy cloth."

Rationale:

A. "Keep initial pressure dressing in place for 1 week after surgery":
The pressure dressing is typically changed more frequently to monitor the incision site for signs of infection and to ensure appropriate healing. Keeping it in place for a week without monitoring could increase the risk of infection and complications.

B. "Leave the prosthesis in place when going to bed":
It is generally recommended to remove the prosthesis at night to allow the residual limb to rest and prevent skin irritation or pressure sores. Leaving it on overnight can lead to unnecessary strain on the limb.

C. "Avoid extension of the hips when lying down":
Clients should actually avoid prolonged hip flexion, not extension, as it can lead to hip contractures. Instead, they should try to lie prone periodically to stretch the hip and reduce the risk of contracture formation.

D. "Clean the prosthesis using a damp, soapy cloth":
Using a damp, soapy cloth to clean the prosthesis helps maintain hygiene and prevents skin irritation. It's important to keep the prosthesis clean to avoid any buildup of bacteria or dirt, which can affect both the device and the residual limb’s health.
