Question 1 of 5
A physician ordered 1/4 strength Isomil 12 oz via nasogastric tube over 6 hours. How much solvent (water) will be needed?
Correct Answer: B
Rationale: The correct answer is B: 270 mL.
To calculate the amount of solvent needed, we first find the total volume of the Isomil solution: 12 oz x 1/4 = 3 oz. Next, convert 3 oz to mL (1 oz = 30 mL), so 3 oz x 30 mL/oz = 90 mL. Since the Isomil solution will be administered over 6 hours, divide 90 mL by 6 hours to get the rate per hour: 90 mL / 6 hours = 15 mL/hour. Finally, multiply the rate per hour by the total duration (6 hours): 15 mL/hour x 6 hours = 90 mL.
Therefore, the total amount of solvent needed is 90 mL, and when added to the 12 oz of Isomil, the total volume is 270 mL. Other choices are incorrect because they do not follow the correct calculations based on the given information.
