Final answer:
To calculate the total urine output in 24 hours if the hourly output remains constant, you need to multiply the hourly output by the number of hours in a day.
Step-by-step explanation:
To calculate the total urine output in 24 hours if the hourly output remains constant, you need to multiply the hourly output by the number of hours in a day. In this case, the hourly output is 0.9 mL and there are 24 hours in a day. So, the total urine output in 24 hours is 0.9 mL/hour * 24 hours = 21.6 mL. Therefore, none of the given options A) 10,000 mL/24 hr, B) 20,000 mL/24 hr, C) 12,000 mL/24 hr, D) 16,000 mL/24 hr, match the correct answer.
