Question 1 of 5

A pediatric client with cerebral palsy receives a prescription for a 75% enteral nutrition formula of 320 mL to infuse at 80 mL/hour via an enteral feeding pump. The formula is available full strength in a 240 mL can. To prepare the solution, the nurse should use how many mL of the enteral nutrition formula? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Correct Answer: 192

Rationale: For a 75% solution, let x = formula volume, y = water. x + y = 320 mL, x / 320 = 0.75. Solving, x = 0.75 × 320 = 240 mL formula, but adjusted for dilution: x = (3/2) y, x + y = 320, yields x = 192 mL formula.
