A nurse is discussing postpartum depression with a newly licensed nurse. Which of the following statements by the newly licensed nurse indicates an understanding of this condition?

Choice A rationale While rare, some severe cases of postpartum psychosis, a distinct and more severe mental illness than postpartum depression, can involve psychotic behavior. However, it is not a common manifestation of postpartum depression itself, which primarily involves mood disturbances like profound sadness and anhedonia, impacting daily functioning. Choice B rationale Harming the infant is an extremely rare and severe outcome, typically associated with postpartum psychosis, not commonly seen in postpartum depression. Postpartum depression manifests primarily as intense sadness, anxiety, fatigue, and feelings of inadequacy, which can impair maternal-infant bonding but rarely directly leads to infant harm. Choice C rationale Postpartum depression typically has a later onset, often appearing within four weeks to six months after childbirth, rather than within 48 hours. The initial 48 hours are more commonly associated with "baby blues," a transient period of mood lability due to hormonal shifts and sleep deprivation. Choice D rationale A history of depression, whether antepartum depression or a prior episode of major depressive disorder, significantly increases a woman's susceptibility to developing postpartum depression. Neurobiological vulnerabilities and psychosocial stressors interact, predisposing individuals with pre-existing mood disorders to recurrence in the postpartum period.
