Which of the following statements accurately describes a characteristic of the newborn immune system?

Choice A rationale

Shivering is not a primary concern for newborns as they have limited ability to shiver. Instead, they rely on non-shivering thermogenesis to maintain body temperature.

Choice B rationale

Cold stress is a significant concern for newborns as it can lead to hypothermia, increased oxygen consumption, and metabolic acidosis. Placing a newborn under a radiant heat warmer helps maintain their body temperature and prevent cold stress.

Choice C rationale

Brown fat production is a natural process in newborns that helps generate heat. However, the primary purpose of using a radiant heat warmer is to prevent cold stress, not to stimulate brown fat production.

Choice D rationale

Basal metabolic rate reduction is not the primary concern. The focus is on preventing cold stress and maintaining the newborn’s body temperature.

Choice A rationale

Applying a 1-2 cm ribbon from outer to inner canthus is incorrect because it increases the risk of contamination and infection by moving from a less clean area to a more clean area.

Choice B rationale

Applying a 2-3 inch ribbon from inner to outer canthus is incorrect because the length of the ribbon is too long and the direction is not recommended for preventing contamination.

Choice C rationale

Applying a 1-2 cm ribbon from inner to outer canthus is correct as it minimizes the risk of contamination by moving from a cleaner area to a less clean area, ensuring proper application of the ointment.

Choice D rationale

Applying a 1-2 inch ribbon to the upper eyelid is incorrect because the upper eyelid is not the recommended site for application, and the length of the ribbon is too long.
