A nurse is assisting with the admission of a client who has hyperemesis gravidarum. Which of the following laboratory tests is the priority to complete?

(A) "You should recognize that your baby sucking on his hands is a hunger cue."
Recognizing hunger cues is crucial for successful breastfeeding. Early hunger cues like sucking on hands, rooting, and lip-smacking indicate that the baby is ready to feed. Responding to these cues can help establish a good breastfeeding routine and ensure the baby gets adequate nutrition before becoming too distressed to feed effectively.

(B) "You should feed your baby for 10 minutes on each breast."
Feeding duration can vary significantly among babies. Some may need longer than 10 minutes on each breast, while others might feed more efficiently in a shorter time. Instead of a strict time limit, it's important to encourage the mother to allow the baby to feed until they show signs of being full, such as pulling away from the breast or falling asleep.

(C) "You should feed your baby six times a day."
Newborns typically need to feed more frequently than six times a day. Most newborns breastfeed 8-12 times in 24 hours. Limiting feeds to six times a day may not provide sufficient nutrition and can affect the baby’s growth and milk supply.

(D) "You should wake your baby at least every 6 hours at night for feedings."
Newborns, especially in the first few weeks, often need to be fed more frequently than every 6 hours, including at night. Typically, it’s recommended to wake a baby to feed if they sleep for more than 4 hours at a time in the early weeks to ensure adequate intake and to help establish the mother’s milk supply.

(A) Retained placental fragments:
Retained placental fragments can lead to postpartum hemorrhage (PPH) due to incomplete expulsion of the placenta or membranes, which can cause ongoing bleeding. Failure of the uterus to contract effectively after childbirth to compress blood vessels at the placental site can result in excessive bleeding. This is a significant risk factor for PPH and requires prompt intervention to prevent complications.

(B) Urinary tract infection:
While urinary tract infections (UTIs) can occur in the postpartum period, they are not typically considered significant risk factors for postpartum hemorrhage. UTIs are more commonly associated with symptoms such as dysuria, frequency, and urgency.

(C) Oligohydramnios:
Oligohydramnios, a condition characterized by decreased amniotic fluid volume, is not a direct risk factor for postpartum hemorrhage. Oligohydramnios may be associated with other pregnancy complications but is not directly related to the risk of postpartum hemorrhage.

(D) Breech presentation:
While breech presentation (when the baby's buttocks or feet are positioned to deliver first) may increase the risk of complications during labor and delivery, it is not specifically linked to postpartum hemorrhage. Breech presentation may necessitate interventions such as cesarean section delivery to reduce the risk of birth-related complications, but it is not a direct risk factor for postpartum hemorrhage.
