A nurse is reinforcing teaching with a client about various contraceptive methods. Which of the following statements should the nurse include in the teaching?

Answer: B. Determine the newborn's respiratory rate.

Rationale:

A. Weigh the newborn's wet diaper:
While monitoring fluid output is important in assessing hydration status and overall health, it is not the immediate priority. In the context of a newborn with neonatal abstinence syndrome (NAS), the respiratory status takes precedence, especially given that withdrawal can affect respiratory function.

B. Determine the newborn's respiratory rate:
Assessing the respiratory rate is crucial, as newborns with NAS may experience respiratory distress, including increased respiratory effort or apnea. Identifying any respiratory issues early allows for prompt intervention, which is vital for the newborn's safety and well-being. Ensuring adequate respiratory function is a priority in this population.

C. Auscultate the newborn's bowel sounds:
While assessing bowel sounds is relevant to monitoring gastrointestinal function and potential withdrawal symptoms, it is not the immediate priority. Changes in bowel sounds may occur due to the syndrome, but respiratory assessment should come first to ensure stability.

D. Swaddle the newborn in blankets:
Swaddling can provide comfort to a newborn with NAS; however, it is not the first action to take. Comfort measures are important, but they should follow critical assessments of the newborn's respiratory and overall clinical status to ensure safety.

(a) Serum bilirubin:
While serum bilirubin can provide useful information about liver function, it is not the most immediate concern for a client with hyperemesis gravidarum. This condition primarily involves severe nausea and vomiting, which can lead to dehydration and ketosis.

(b) Liver enzymes:
Liver enzymes can be elevated in hyperemesis gravidarum, but they are not the primary concern. The immediate priority is to assess the extent of dehydration and metabolic disturbances.

(c) Urinalysis for ketones:
This test is the priority because it helps determine the extent of dehydration and ketosis. In hyperemesis gravidarum, severe vomiting can lead to significant fluid and electrolyte imbalances and ketosis, which need to be identified and corrected promptly to prevent further complications.

(d) CBC:
A complete blood count (CBC) provides useful information about overall health and can identify anemia or infection, but it is not the priority for immediate assessment of hyperemesis gravidarum. The immediate need is to evaluate hydration status and ketosis, which is best done through urinalysis for ketones.
