Final answer:
The correct descriptions for A and B are postpartum bliss and postpartum blues, respectively. Postpartum bliss refers to the elation after childbirth, while postpartum blues involves emotional changes that peak around the fifth day and resolve by the tenth day.
Step-by-step explanation:
The correct answer to the question is c. A: Postpartum bliss; B: Postpartum blues. The period characterized by heightened joy and feelings of well-being after giving birth is known as postpartum bliss, and matches the description given for A. Meanwhile, the emotional lability, depression, sadness, and other symptoms described for B match the definition of postpartum blues, which typically peaks around the fifth day after birth and subsides by the tenth day. It is important to differentiate postpartum blues from postpartum depression, which is more severe and may require clinical treatment.
After giving birth, along with these emotional changes, the person will also experience physical adjustments such as postpartum uterine contractions that limit blood loss and a vaginal discharge called lochia.
