A patient is receiving a 200 mL bolus of 0.9% normal saline (NS) to be infused over 20 minutes. The nurse should set the infusion pump to deliver how many mL/hour?
(Enter numeric value only.)
The Correct Answer is ["600"]
The correct answer is 600 mL/hour. To find the answer, we can use the following formula:
(mL/hour) = (mL/minute) x 60
Substituting the given values, we get:
(mL/hour) = (200 / 20) x 60
Simplifying, we get:
(mL/hour) = 10 x 60
(mL/hour) = 600
Therefore, the nurse should set the infusion pump to deliver 600 mL/hour of 0.9% NS to the patient.

Correct Answer is ["240"]
Explanation
To find the answer, we can use the following steps:
- Calculate the amount of water needed to dilute the formula to 75% by subtracting the volume of the prescribed solution from the volume of the full strength formula
- Subtract the amount of water from the volume of the can to get the amount of enteral nutrition formula
- Round the result to the nearest whole number
Using these steps, we get:
- (water in mL) = (320) - (240) = 80 mL
- (enteral nutrition formula in mL) = (240) - (80) = 160 mL
- (rounded enteral nutrition formula in mL) = 160 mL
Therefore, the nurse should use 160 mL of enteral nutrition formula from the can to prepare the solution.
Correct Answer is ["42"]
Explanation
To find the answer, we can use the following formula:
(gtt/min) = (mL/hour) x (gtt/mL) / 60
Substituting the given values, we get:
(gtt/min) = (1000 / 8) x (20) / 60
Simplifying, we get:
(gtt/min) = 125 x 20 / 60
(gtt/min) = 41.667
(rounded gtt/min) = 42
Therefore, the nurse should regulate the infusion to deliver 42 gtt/minute of lactated Ringer's.
