A client with a gastrostomy tube (GT) receives a prescription for Osmolite® 1/2 strength enteral formula at 80 ml/hour. To prepare a 4 hour solution, the nurse should dilute the full-strength formula with how many ml of water? (Enter numeric value only.)
The Correct Answer is ["160"]
To prepare a 4-hour solution of Osmolite® 1/2 strength enteral formula at 80 ml/hour, the nurse will need to dilute the full-strength formula with a certain amount of water.
Step 1: Calculate the total volume of the 1/2 strength formula needed for 4 hours:
Total Volume = Infusion Rate (mL/hour) x Infusion Time (hours)
Total Volume = 80 mL/hour x 4 hours
Total Volume = 320 mL
Step 2: Determine the volume of full-strength Osmolite® needed:
Since the desired solution is 1/2 strength, we need to dilute the full-strength formula by half.
Volume of Full-Strength Osmolite® = Total Volume / 2
Volume of Full-Strength Osmolite® = 320 mL / 2
Volume of Full-Strength Osmolite® = 160 mL
Step 3: Calculate the volume of water needed to dilute the full-strength Osmolite®:
Volume of Water = Total Volume - Volume of Full-Strength Osmolite®
Volume of Water = 320 mL - 160 mL
Volume of Water = 160 mL
Therefore, the nurse should dilute the full-strength Osmolite® with 160 mL of water to prepare a 4-hour solution.

Correct Answer is ["200"]
Explanation
To calculate the infusion rate, we'll use the following formula:
Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)
First, convert minutes to hours:
75 minutes x (1 hour / 60 minutes) = 1.25 hours
Then, plug in the values into the formula:
Infusion Rate = 250 mL / 1.25 hours
Calculating the result:
Infusion Rate ≈ 200 mL/hour
Therefore, the nurse should program the secondary infusion pump to deliver 200 mL/hour.
Correct Answer is ["7"]
Explanation
To calculate the number of tablets needed, we'll set up a proportion:
x tablets / 3.5 mg = 1 tablet / 0.5 mg
Cross-multiplying:
0.5x = 3.5
Solving for x:
x = 3.5 / 0.5
x = 7
Therefore, the nurse should administer 7 tablets of benztropine for each dose.
