A client is receiving a continuous tube feeding of 60 mL/hr. How many calories will be received in 12 hours if the formula is 1.2 cal/mL?

The correct answer is: 864

To determine the total number of calories the client will receive in 12 hours from a continuous tube feeding of 60 mL/hr using a formula that provides 1.2 calories per mL, follow these steps: First, calculate the total volume of formula administered over 12 hours. Since the feeding rate is 60 mL/hr, the total volume for 12 hours is: 60 mL/hr × 12 hr = 720 mL. Next, to find the total caloric intake, multiply the total volume of the formula by the number of calories per mL. Given the formula provides 1.2 calories per mL, the calculation is: 720 mL × 1.2 cal/mL = 864 calories. Thus, the client will receive a total of 864 calories in 12 hours, making that the correct answer. This methodical approach ensures you accurately calculate caloric intake based on the feeding rate and caloric density of the formula.
