A postpartum nurse has received an exchange report on the four following mother-baby couplets.Based on the provided information, which couplet should the nurse first assess?

Choice A rationale This scenario presents potential issues related to maternal-infant bonding and psychosocial adaptation, indicated by the mother referring to her baby as "it" and requesting nursery care. While important for long-term well-being, this is a psychosocial concern, and the immediate physiological stability of mother-baby couplets, especially related to hemorrhage risk, generally takes precedence in initial triage. Continuous monitoring and support are required before discharge. Choice B rationale The client's assessment findings of a G5P4 status (multiparity), prolonged labor (20 hours), labor augmentation, and a large baby (4500 grams or >4000 grams) are all significant risk factors for postpartum hemorrhage (PPH), specifically due to uterine atony. A fundus 2 cm above the umbilicus suggests the uterus is not contracting adequately, increasing the risk of excessive blood loss. This requires immediate assessment and intervention to prevent hypovolemic shock. Normal uterine position post-delivery is at or below the umbilicus. Choice C rationale Difficulty breastfeeding is a non-emergent concern related to lactation and infant feeding, not a direct threat to the mother's or infant's immediate physical stability. The mother's fundus is firm, indicating good uterine involution and a low risk of immediate hemorrhage. Lochia is also appropriate for 36 hours postbirth. The couplet is physiologically stable and can be assessed after higher-risk clients. Choice D rationale This client is stable following a cesarean birth. Vital signs are within normal ranges: blood pressure (115/75 mm Hg) is normal (systolic 90-140 mm Hg, diastolic 60-90 mm Hg), pulse (80 bpm) is normal (60-100 bpm), respiration (18 breaths/min) is normal (12-20 breaths/min), and temperature (98.6°F or 37°C) is normal (97.8-99.1°F or 36.5-37.3°C). Intrathecal morphine requires vigilance for respiratory depression, but her current rate is normal, suggesting no acute toxicity.
