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.

When instructing a client on self-administration of nasal drops, the nurse should recommend the supine position. In the supine position, the client lies on their back with the head slightly elevated. This position allows for easy access to the nostrils and facilitates the proper instillation of the nasal drops.

The other options are not recommended for instillation of nasal drops for various reasons:

a) Sims position: Simsposition is a side-lying position with the upper leg flexed. This position is often used for rectal examinations or procedures and is not suitable for instilling nasal drops.

b) Prone position: Prone position refers to lying face down. It is not ideal for administering nasal drops as it

can obstruct proper access to the nostrils and make it difficult to instill the drops accurately.

d) Orthopneic position: Orthopneic position is a sitting position with the upper body supported by pillows. It is commonly used by individuals with respiratory distress to facilitate breathing. However, it is not specifically recommended for administering nasal drops as it may not provide optimal access to the nostrils for proper instillation.
