A mother is concerned about what might have caused a heat rash on her infant. The nurse observes tiny pinhead-sized reddened papules on the infant's neck and axilla. What does the nurse explain as the most likely cause of this rash?

A. Empty bladder completely with each void: Ensuring the bladder is completely emptied helps to reduce the risk of residual urine, which can promote bacterial growth and increase the risk of UTIs.
B. Avoid bubble baths: Bubble baths can irritate the urethra and promote bacterial growth, increasing the risk of UTIs. Avoiding them helps in prevention.
C. Increase fiber intake: Increasing fiber intake is not directly related to UTI prevention and is more relevant to digestive health.
D. Wear nylon underpants; Nylon underpants can trap moisture and create a warm environment that supports bacterial growth. Cotton underwear is recommended instead.
E. Watch for manifestations of infection: Being vigilant for signs of infection such as fever, pain, or changes in urination patterns is crucial for early detection and treatment of UTIs.

A. Wash bed linens in cold water. Washing bed linens in cold water is ineffective for killing pinworm eggs. Hot water should be used to properly sanitize linens and kill the eggs.
B. Clean the bathroom with bleach solution. While cleaning the bathroom with bleach can help reduce contamination, it is not a primary or effective measure for preventing pinworm spread and reinfection in a household setting.
C. Keep children's nails short. Keeping nails short reduces the likelihood of the child scratching the perianal area, where pinworm eggs are deposited, and then ingesting the eggs through hand-to-mouth contact. This helps prevent the spread and reinfection of pinworms.
D. Dress child in loose-fitting underwear. Loose-fitting underwear does not specifically help in preventing the spread or reinfection of pinworms. Tight-fitting underwear may actually be better to prevent the spread of eggs to other surfaces.
