Questions: A client with a gastrostomy tube (GT) receives a prescription for a 250 ml bolus feeding of Glucerna 60% enteral formula. The nurse should dilute the full-strength formula with how many ml of water? (Enter numeric value only).

Solution Steps

To solve this problem, we need to determine how much water should be added to the full-strength formula to achieve a specific dilution. The problem states that the formula is 60% enteral, which means 60% of the mixture is the formula, and the remaining 40% should be water. We need to calculate the amount of water that makes up 40% of the total volume.

1. Let \( x \) be the total volume of the diluted formula.
2. Since 60% of \( x \) is the formula, we have \( 0.6x = 250 \) ml.
3. Solve for \( x \) to find the total volume of the diluted formula.
4. Subtract 250 ml from \( x \) to find the amount of water needed.

To find the total volume of the diluted formula, we use the relationship that 60% of the total volume is the formula. Given that the formula volume is 250 ml, we set up the equation:

\[ 0.6x = 250 \]

Solving for \( x \), the total volume of the diluted formula:

\[ x = \frac{250}{0.6} = 416.\overline{6} \text{ ml} \]

The amount of water needed is the difference between the total volume of the diluted formula and the volume of the formula itself:

\[ \text{Water Volume} = x - 250 = 416.\overline{6} - 250 = 166.\overline{6} \text{ ml} \]
