A client who had a small bowel resection two weeks ago is receiving 3/4 strength Ensure feedings 275 ml every 4 hours via nasogastric tube. Full strength Ensure is available in a 240 ml can. The nurse should use how many ml of Ensure to prepare the feeding? (Enter numeric value only. Round to nearest whole number if needed.)
The Correct Answer is ["206"]
Calculation for 3/4 Strength Ensure Feeding
Prompt: To determine how many milliliters of full-strength Ensure to use to prepare a 3/4 strength feeding.
Given:
Desired volume of 3/4 strength Ensure: 275 mL
Strength required: 3/4
Formula:
Amount of full-strength Ensure = Total volume x Strength required
Calculation:
Amount of full-strength Ensure = 275 mL x (3/4)
Amount of full-strength Ensure = (275 x 3) / 4
Amount of full-strength Ensure = 825 / 4
Amount of full-strength Ensure = 206.25 mL
Rounding to the nearest whole number:
Amount of full-strength Ensure = 206 mL
Therefore, the nurse should use 206 mL of full-strength Ensure to prepare the feeding.

Correct Answer is ["16.8"]
Explanation
To calculate the volume of IV solution needed to dilute the nafcillin, we'll follow these steps:
Step 1: Calculate the total volume of the diluted solution:
Desired Concentration (mg/mL) = Prescribed Dose (mg) / Total Volume (mL)
Rearranging the formula to solve for Total Volume:
Total Volume (mL) = Prescribed Dose (mg) / Desired Concentration (mg/mL)
Total Volume = 800 mg / 40 mg/mL
Total Volume = 20 mL
Step 2: Calculate the volume of nafcillin solution to be added:
Volume of Nafcillin Solution = Prescribed Dose (mg) / Concentration of Nafcillin (mg/mL)
Volume of Nafcillin Solution = 800 mg / 250 mg/mL
Volume of Nafcillin Solution = 3.2 mL
Step 3: Calculate the volume of IV solution needed to dilute:
Volume of IV Solution = Total Volume - Volume of Nafcillin Solution
Volume of IV Solution = 20 mL - 3.2 mL
Volume of IV Solution = 16.8 mL
Therefore, the nurse should add 16.8 mL of IV solution to the volume control device to dilute the nafcillin.
Correct Answer is ["1.4"]
Explanation
To calculate the volume of penicillin to be administered, we can use the following formula:
Volume (mL) = Desired Dose (Units) / Concentration (Units/mL)
Plugging in the given values:
Volume (mL) = 700,000 Units / 500,000 Units/mL
Calculating the result:
Volume (mL) = 1.4 mL
Therefore, the nurse should administer 1.4 mL of penicillin.
