Which of the following assessments indicates a potential complication in a postpartum client?

In the context of postpartum assessments, sharp abdominal pain can indicate a potential complication. After childbirth, it is expected for the uterus to contract and for women to experience some discomfort as part of the healing process. However, sharp or severe abdominal pain might suggest complications such as uterine atony (failure of the uterus to contract properly), retained placental fragments, or even infection. These conditions require prompt assessment and intervention, as they can lead to significant health issues if not addressed.

In contrast, an increased appetite is often a normal response as the body begins to recover from childbirth and can signify that the nursing mother is nourishing herself adequately. Stable blood pressure indicates that a patient is likely not experiencing severe blood loss or cardiovascular issues, while an improved mood is generally a positive sign, reflecting emotional adjustment after delivery. Each of these other options indicates a normal or healthy response, making sharp abdominal pain a notable exception that warrants further investigation.
