The patient is most likely experiencing postpartum blues or depression. It is characterized by feelings of irritability, anxiety, and other signs of depression following the delivery. The condition is more common among women who have perinatal issues such as marital and financial problems, lack of social support, and recent death of loved ones. It is important for the nurse to attend the needs of the patient and allow her to express her emotions and feelings. It is not appropriate to immediately impose on the patient love and care for the baby, because it may reinforce her animosity.
