Final answer:
The patient receives 1200 mL of a concentrated formula daily, which equates to 960 mL of actual fluid. If the patient's daily fluid requirement is estimated at 1500 mL, there is a deficit of 540 mL, meaning the patient needs an additional 540 mL of fluid per day to meet their hydration needs.
Step-by-step explanation:
To calculate the daily fluid requirement for a patient, we can use the information provided. The patient receives a concentrated formula at a rate of 50 mL per hour. To find the total volume of formula received in a day, we multiply the hourly rate by the number of hours in a day:
50 mL/hr × 24 hrs = 1200 mL/day.
Since the formula is concentrated at 80%, we need to adjust our calculation to determine the actual fluid content the patient receives:
1200 mL/day × 0.80 (80%) = 960 mL/day of fluid.
However, according to the question, the estimated daily fluid requirement for the patient is 1500 mL. Hence, there is a deficit in fluid intake:
1500 mL (required) - 960 mL (received from formula) = 540 mL/day.
This indicates that the patient would require an additional 540 mL of fluid per day to meet the estimated fluid requirement.
