For a TPN solution delivered at 50 ml/hr at 3/4 strength, how much of the formula and water is appropriate?

To find the appropriate amounts of formula and water for a TPN (Total Parenteral Nutrition) solution delivered at 50 ml/hr at 3/4 strength, we first need to determine the total volume of the TPN solution required in a 24-hour period.

Calculating the total volume for 24 hours:

50 ml/hr * 24 hr = 1200 ml

Since the solution is at 3/4 strength, we need to calculate how much of that total volume accounts for the formula and how much is water. The 3/4 strength indicates that 75% of the total volume is made up of the formula, and the remaining 25% is water.

Calculating the amount of formula:

0.75 * 1200 ml = 900 ml of formula

Now, calculating the amount of water:

1200 ml - 900 ml = 300 ml of water

Thus, the appropriate amounts in the correct configuration show that for the TPN solution at 50 ml/hr at 3/4 strength, a total of 900 ml should be the formula, and 300 ml should be water. This makes option B the right choice, as it accurately reflects the calculated requirements for a balanced T
