Choice A rationale Bladder distention upon palpation indicates urinary retention, meaning the client is unable to void effectively or empty the bladder completely. In the postpartum period, a full bladder can inhibit uterine contraction and increase the risk of postpartum hemorrhage because a distended bladder displaces the uterus, preventing it from clamping down appropriately. The normal range for post-void residual volume is typically less than 100 mL. Choice B rationale Not feeling the urge to urinate may be due to decreased bladder sensation following labor and delivery or effects of regional anesthesia, which can lead to urinary retention. Effective voiding is characterized by the ability to sense the urge to void, initiate urination, and empty the bladder, typically passing at least 150 mL per void after catheter removal. Choice C rationale Lateral displacement of the uterus is a common sign of a distended bladder. A full bladder pushes the uterus out of its normal midline position, impairing its ability to contract effectively, which increases the risk for uterine atony and subsequent postpartum hemorrhage. The fundus should remain firm and in the midline position after effective voiding. Choice D rationale The firming of the fundus with massage indicates that the uterus is contracting, which is essential for preventing postpartum hemorrhage by compressing the blood vessels at the placental site. Effective voiding allows the uterus to remain in its midline position, facilitating proper involution and contractility, which is reflected by a firm fundus.
