A client returning from surgery has a prescription for an IV of 0.9% sodium chloride to be infused at 250 ml over 3 hours. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["83"]
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 = 250 mL / 3 hours
Calculating the result:
Infusion Rate ≈ 83.33 mL/hour
Rounding to the nearest whole number, the nurse should program the infusion pump to deliver 83 mL/hour.

Correct Answer is ["2"]
Explanation
To calculate the number of tablets needed, we can set up a proportion:
x tablets / 30 mg = 1 tablet / 20 mg
Cross-multiplying:
20x = 30
Solving for x:
x = 30 / 20
x = 1.5
Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.
Therefore, the nurse should administer 2 tablets of baclofen.
Correct Answer is ["160"]
Explanation
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.
