A nurse is caring for a client who has impaired renal function. The nurse should notify the provider if the client's hourly urine output falls below what amount? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Step 1: Identify the minimum acceptable urine output for an adult Adequate urine output = 0.5 mL/kg/hr Step 2: Apply the standard adult minimum For an average adult (approximately 60 kg): 0.5 mL × 60 kg = 30 mL/hr Step 3: Round to the nearest whole number 30 → 30 mL/hr
