A postpartum client comes to the clinic for her routine 6-week visit. The nurse assesses the client and suspects that she is experiencing subinvolution based on which of the following?

Choice A rationale A nonpalpable fundus (uterus) below the symphysis pubis is expected after approximately 10 to 14 days postpartum as the uterus involutes. Subinvolution, conversely, is characterized by a larger-than-expected uterus for the period, meaning the fundus would likely still be palpable and higher than anticipated, indicating failure of the myometrium to contract effectively back to its pre-pregnancy size. Choice B rationale Bruising on arms and legs is a finding related to potential coagulopathy, trauma, or a bleeding disorder, which is not a direct or characteristic sign of subinvolution. Subinvolution is a local uterine condition involving delayed return of the uterus to its non-pregnant state, primarily manifesting as persistent or heavier-than-normal lochia and a boggy uterus. Choice C rationale Fever is a classic sign of postpartum infection, such as endometritis, which can be an underlying cause of subinvolution, but it is not the primary defining sign of subinvolution itself. Subinvolution is defined anatomically by the delayed process of involution, with the main clinical feature being altered lochia pattern, not necessarily a systemic sign like fever. Choice D rationale Moderate lochia serosa lasting beyond the expected time frame (typically 22-27 days) is a primary clinical indicator of subinvolution. This persistent bleeding, resulting from inadequate myometrial contraction and failure to compress the uterine blood vessels effectively, indicates that the normal shedding and healing process of the endometrium is delayed or incomplete.
