A nurse is reinforcing teaching with a client who is postpartum about bathing her newborn. Which of the following statements by the client indicates a need for further teaching?

A. This condition typically results from excessive loss of acid, often due to vomiting or diuretics. It is not the most likely concern in a cold environment with an infant who has been crying and kicking.

B. A cold environment can lead to nonshivering thermogenesis in newborns, where they metabolize brown fat to generate heat. This process can lead to increased lactic acid production, potentially causing metabolic acidosis. The infant's fatigue following crying and kicking may indicate that the body has expended significant energy to stay warm, making metabolic acidosis a priority concern.

C. While hunger could be a reason for crying, it is not the priority concern in this scenario where environmental cold and fatigue are present.

D. Overstimulation might cause crying, but the environmental cold and subsequent risk of metabolic acidosis are more critical concerns in this context.

Rooting. Choice A rationale:

The Moro reflex is a startle reflex characterized by the infant's sudden extension and abduction of the arms in response to a loud noise or sudden movement. It is not involved in the initiation of sucking and is unrelated to breastfeeding.

Choice B rationale:

The rooting reflex is a crucial reflex that helps initiate sucking in newborns. When the infant's cheek is stroked or touched, they will turn their head toward the stimulus and open their mouth, preparing for feeding. This reflex helps the infant find the mother's nipple and begin breastfeeding effectively.

Choice C rationale:

The stepping reflex is a primitive reflex observed in newborns when held upright with their feet touching a solid surface. The baby will make stepping movements, mimicking walking. However, this reflex is not related to the initiation of sucking and breastfeeding.

Choice D rationale:

The Babinski reflex is a reflex in which the big toe extends upward and the other toes fan out when the sole of the foot is stimulated. This reflex is present in newborns and disappears as the child grows older. It is not involved in the initiation of sucking.
