Final answer:
Couplet care, also known as mother-baby care or rooming-in, is the approach where one nurse provides care for both mother and infant, encouraging bonding and easing transition to home life.
Step-by-step explanation:
The nursing care management approach in which one nurse cares for both the mother and her infant is known as couplet care, which is also called mother-baby care or rooming-in.
This approach promotes family bonding, encourages optimal newborn feeding practices, and eases the transition to home life due to the continuity of care. The nurse assigned to a family unit of mother and newborn is responsible for assessing, planning, and implementing care for both, which may include promoting breastfeeding, teaching about newborn care, and monitoring the health status of mother and child.
