The healthcare provider prescribes 1 liter of lactate Ringers to infuse in 8 hours. The IV administration set delivers 15 gtt/mL. How many mL/hour should the nurse program the infusion pump?
(Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["125"]
- Calculate the infusion rate in mL/hour using the formula: infusion rate (mL/hour) = volume (mL) / time (hours)
- Plug in the given values: infusion rate (mL/hour) = 1000 mL / 8 hours
- Simplify the expression: infusion rate (mL/hour) = 125 mL/hour
- The nurse should program the infusion pump to deliver 125 mL/hour

Correct Answer is ["18"]
Explanation
To determine the infusion rate, we'll use the following formula:
Infusion rate (mL/hr) = Desired dose (units/hr) / Concentration of heparin (units/mL)
First, calculate the concentration of heparin in the IV bag:
- 20,000 units / 250 mL = 80 units/mL
Then, plug the values into the formula:
- Infusion rate = 1,400 units/hr / 80 units/mL = 17.5 mL/hr
Therefore, the nurse should program the infusion pump to deliver 18 mL/hr (rounded to the nearest whole number).
Correct Answer is ["0.41"]
Explanation
- To calculate the dose, divide 4800 mg by 400 mg to get 12 mL.
- To convert mL to ounces, multiply 12 mL by 0.0338 to get 0.4056 ounces.
- To round to the nearest hundredth, the final answer is 0.41 ounces.
- The nurse should instruct the client to take 0.41 ounces of magnesium hydroxide at bedtime.
