What intervention should a nurse anticipate for a postoperative client with dark yellow urine draining at 25 ml/hr?

When considering the appropriate intervention for a postoperative client exhibiting dark yellow urine with a low output of 25 ml/hr, administering a fluid bolus is crucial. This choice addresses the potential issue of dehydration, which may be indicated by the concentrated, dark yellow urine. In the postoperative setting, fluid balance can be affected by factors such as surgical stress, limited oral intake, and potential fluid loss during surgery.

A fluid bolus would help restore adequate hydration and may stimulate kidney function to improve urine output. This intervention aims to ensure that the kidneys are receiving sufficient fluid to produce an adequate volume of urine, as well as to maintain electrolyte balance and overall homeostasis.

In contrast, while increasing oral intake may be beneficial as the client recovers, it may not be feasible if the client is unable to tolerate fluids adequately or if their postoperative condition does not yet allow for increased oral intake. Calling the physician might be necessary if the situation does not improve after initial interventions, but the immediate step is to address the possible dehydration with a fluid bolus. Encouraging ambulation can promote overall recovery and potentially aid in urine output, but it is secondary to the need for adequate hydration, particularly when the urine output is already significantly low.
