What is the priority action for a nurse observing a postoperative client with only 20 mL of urine output in an hour?

The priority action of checking the client's overall intake and output record is essential in this scenario as it provides the nurse with critical context about the patient’s fluid balance. By reviewing the intake and output, the nurse can better understand whether the low urine output is a sudden change from the patient's baseline or part of a trend. This context aids in determining the most appropriate course of action moving forward.

Monitoring intake and output helps assess kidney function and fluid status, especially in postoperative patients who may experience transient changes in urine output due to factors such as fluid shifts, effects of anesthesia, or surgical stress. Once this information is gathered, the nurse can make a more informed decision about whether to notify the healthcare provider, administer fluids, or increase IV rates, depending on the overall clinical picture.

Taking this step before other interventions allows for a thorough and accurate evaluation of the situation, ensuring that any necessary actions taken afterward are based on comprehensive information rather than assumptions about the patient’s condition.
