A nurse is collecting a blood phenylketonuria (PKU) test for a newborn prior to discharge.The newborn's guardian asks the nurse what a positive PKU test would mean.
Which of the following statements should the nurse make?

Choice A rationale

Hypertension is not a characteristic finding of hyperemesis gravidarum, which primarily affects fluid balance and nutritional status.

Choice B rationale

Dry mucous membranes are a sign of dehydration, commonly associated with hyperemesis gravidarum due to excessive vomiting.

Choice C rationale

Tachycardia can result from dehydration and electrolyte imbalances seen in hyperemesis gravidarum.

Choice D rationale

Poor skin turgor indicates dehydration, a common symptom of hyperemesis gravidarum.

Choice E rationale

Polyuria is not typical in hyperemesis gravidarum; the condition usually leads to dehydration, reducing urine output.

Based on the assessment findings, the nurse identifies that the client is at greatest risk for developing:

1. Postpartum infection
2. Hemorrhage

Here's the

• Postpartum infection: The client has a history of prolonged rupture of membranes and is experiencing a moderate amount of lochia rubra, both of which increase the risk of infection. Additionally, she reports feeling weak, fatigued, and has a temperature of 38.5°C (101.3°F), which are signs of a possible infection.
• Hemorrhage: The moderate amount of lochia rubra and a boggy fundus above the umbilicus indicate that the client may be at risk for postpartum hemorrhage. The provider's prescription for administering oxytocin if needed also suggests a concern for uterine atony, which can lead to hemorrhage.
