The correct answer is b. "I will apply petroleum jelly to the penis with each diaper change."

Choice A rationale:

• It is incorrect to focus on removing all yellow exudate.A small amount of yellow exudate is normal during the healing process after circumcision.Attempting to aggressively clean it off can irritate the delicate healing tissues and cause discomfort for the baby.
• Instead,parents should gently cleanse the area with warm water during diaper changes,allowing any mild exudate to naturally drain.

Choice B rationale:

• Applying petroleum jelly with each diaper change is an essential step in promoting healing and preventing discomfort after circumcision.Here's why:
  • Protects against moisture:Petroleum jelly forms a barrier that protects the delicate healing tissues from moisture from urine and feces.This helps to prevent irritation and keeps the area clean.
  • Reduces friction:The lubricating properties of petroleum jelly reduce friction between the penis and the diaper,which can minimize discomfort and pain for the baby.
  • Promotes healing:Petroleum jelly creates a moist environment that promotes healing and reduces scab formation.This helps the circumcision site to heal faster and more comfortably.

Choice C rationale:

• While ensuring a proper diaper fit is important for overall hygiene,it's not the most crucial aspect of post-circumcision care.A snug diaper can put unnecessary pressure on the healing penis,potentially causing irritation and discomfort.It's generally recommended to choose a diaper that fits comfortably without being too tight.

Choice D rationale:

• Using soap to wash the penis is not recommended during the healing process.Soap can be harsh and drying to the delicate tissues,potentially causing irritation and delaying healing.
• Warm water is sufficient for cleansing the area during diaper changes.

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.
