A nurse is assessing a client who is postoperative following abdominal surgery and has an indwelling urinary catheter that is draining dark yellow urine at 25 mL/hr. Which of the following interventions should the nurse anticipate?

A. Dark yellow urine and low urine output (25 mL/hr) may indicate dehydration or decreased fluid intake, so a fluid bolus is indicated to promote kidney perfusion. B. Continuous bladder irrigation is typically indicated if there is concern about urinary tract obstruction or blood clots, not for low urine output alone. C. Clamping the catheter can further hinder urine output and is not indicated. D. A urine culture and sensitivity might be necessary if infection is suspected, but the priority is to address hydration first.
