A home health care nurse is reinforcing teaching about breast engorgement with a client who is postpartum and is breastfeeding her newborn. Which of the following client statements indicates an understanding of the teaching?

Choice A rationale:

The fit of the newborn's clothes is not a reliable indicator of hydration. It may vary based on the clothing size or style and does not give a direct measure of the newborn's hydration status. This choice is not appropriate for evaluating hydration and is therefore incorrect.

Choice B rationale:

The number of wet diapers per day is an essential measure for assessing a newborn's hydration. In the first few days after birth, the baby should have at least one wet diaper for each day of life (e.g., one wet diaper on day one, two on day two, etc.). Afterward, the newborn should have around 6-8 wet diapers per day, which indicates adequate hydration. This choice is appropriate and the correct answer.

Choice C rationale:

How often the newborn cries can be influenced by various factors, including hunger, discomfort, or sleepiness. While crying can indicate the baby's needs, it is not a specific or accurate measure of hydration status. Therefore, this choice is not appropriate for evaluating hydration and is incorrect.

Choice D rationale:

The newborn's skin turgor is a measure of skin elasticity, commonly used in adults to assess hydration. However, it is not a reliable indicator of hydration in newborns, as their skin is more elastic and different from adult skin. Skin turgor is not a suitable parameter to evaluate newborn hydration, making this choice incorrect.

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.
