What is the appropriate nursing intervention if a client’s uterus is found to be firm, above the level of the umbilicus, and to the right of midline two hours after giving birth?

A uterus that is found to be firm, elevated above the level of the umbilicus, and positioned to the right of midline suggests a possible distended bladder, which can impede the normal involution of the uterus. When a client's bladder is distended, it can push the uterus up and to the side, leading to potential complications such as increased bleeding or delayed recovery.

Assisting the client to the bathroom to empty her bladder is the most appropriate intervention in this scenario. It helps relieve bladder distension, allowing the uterus to return to its normal position and facilitate proper uterine involution. This intervention not only addresses the physical positioning of the uterus but also contributes to the overall comfort and recovery of the new mother.

Other options like encouraging deep breathing exercises, administering pain medication, or monitoring vital signs closely do not directly address the issue of urinary retention, which is likely causing the uterine deviation in this case. Each of those interventions might be appropriate in different contexts, but they do not target the immediate problem caused by a full bladder.
