A nurse is assessing a postpartum client for signs of postpartum depression. Which of the following symptoms is most indicative of postpartum depression rather than normal postpartum adjustment?

A. Feeling anxious about the baby's health and well-being, but still able to care for the baby effectively Mild anxiety about the baby’s health is a common experience for new mothers and does not necessarily indicate PPD. It becomes concerning if anxiety becomes overwhelming or interferes with daily functioning. B. Experiencing occasional mood swings and irritability while adjusting to the new role of motherhood Mood swings and irritability are normal postpartum adjustments, often due to hormonal changes, sleep deprivation, and new responsibilities. These symptoms typically resolve within a few weeks. C. Feeling overwhelmed and having difficulty sleeping due to the demands of a newborn Feeling overwhelmed and sleep disturbances are common in the postpartum period due to frequent infant care needs. However, severe or persistent sleep disturbances, especially with loss of interest in daily activities, may indicate PPD. D. Persistent feelings of sadness, severe fatigue, and loss of interest in activities, including caring for the baby Postpartum depression is characterized by prolonged sadness, extreme fatigue, withdrawal, and difficulty bonding with the baby. These symptoms extend beyond normal postpartum blues (which typically resolve within two weeks) and require medical intervention, including therapy and possibly medication.
