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 ["60"]
Explanation
To calculate the infusion rate, we'll use the following formula:
Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)
Plugging in the given values:
Infusion Rate = 240 mL / 4 hours
Infusion Rate = 60 mL/hour
Since the feeding is half-strength, the nurse should program the enteral pump to deliver 60 mL/hour.

Explanation
Calculating the Trimethoprim-Sulfamethoxazole Dose
Problem: Administer 120 mg of Bactrim-DS Oral Suspension. The available concentration is 200 mg/5 mL.
Steps:
Set up a proportion:
We want to find the number of milliliters (mL) needed.
We know the desired dose (120 mg) and the concentration of the medication (200 mg/5 mL).
Proportion:
x mL / 120 mg = 5 mL / 200 mg
Cross-multiply:
200x = 600
Solve for x:
x = 600 / 200
x = 3
Answer: The nurse should administer 3 mL of Bactrim-DS Oral Suspension per dose.
