Final answer:
To provide 1800 kcal using a 1.5 kcal/ml formula at full strength, you would need to administer the feeding at a rate of 1200 ml/hr.
Step-by-step explanation:
To calculate the required ml/hr to provide 1800 kcal using a 1.5 kcal/ml formula at full strength, you need to divide the total calorie requirement by the calorie content per milliliter. In this case, the formula provides 1.5 kcal per milliliter. So, the calculation would be: 1800 kcal / 1.5 kcal/ml = 1200 ml/hr.
