A nurse is receiving report on four postpartum clients. Which of the following clients should the nurse plan to attend to first?

A. Changing a perineal pad every 4 hours is within expected postpartum norms for moderate bleeding. This client’s condition does not indicate an urgent issue. B. A urine output of 750 mL over 6 hours is adequate (approximately 125 mL/hr) and does not signal immediate concern. C. Deep tendon reflexes of 1+ in a client receiving IV magnesium sulfate may indicate early magnesium toxicity or impending hyporeflexia. Magnesium sulfate toxicity can lead to respiratory depression and cardiac arrest, making this the highest-priority client. D. Abdominal cramping during breastfeeding is common due to uterine contractions (afterpains) and is generally expected and non-life-threatening. This can be addressed after assessing higher-priority clients.
