Question

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. The nurse explains the cause of this rash is most likely:

1) Allergic reaction to a new food
2) Bacterial infection
3) Viral infection
4) Heat and moisture trapped in skin folds

Answer 1

The cause of the rash is most likely heat and moisture trapped in skin folds, known as a heat rash or miliaria. To prevent and manage heat rash, it's important to keep the affected areas cool and dry and avoid tight clothing.

Step-by-step explanation:

The cause of the rash on the infant's neck and axilla, characterized by tiny pinhead-sized reddened papules, is most likely heat and moisture trapped in skin folds.

This type of rash is commonly known as a heat rash or miliaria.

Heat and moisture trapped in the skin folds can lead to blocked sweat ducts, causing the sweat to be trapped beneath the skin and resulting in a rash.

To prevent and manage heat rash, it is important to keep the affected areas cool and dry, avoid tight clothing, and keep the skin clean.
