The nurse plans to provide the next shift with the IV fluid balance for a client who had a 440 mL secondary infusion that was started 2 hours ago at a rate of 85 mL/hour via an infusion pump. What is the remaining volume to be infused? (Enter numeric value only.)
The Correct Answer is ["270"]
To find the answer, we can use the following formula:
(remaining volume) = (initial volume) - (infused volume)
Substituting the given values, we get:
(remaining volume) = (440) - ((85 x 2))
Simplifying, we get:
(remaining volume) = (440) - (170)
(remaining volume) = 270
Therefore, the remaining volume to be infused is 270 mL.

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.
Correct Answer is ["6"]
Explanation
To find the answer, we can use the following steps:
- Convert the dosage of oxytocin from milliunits/min to units/hour by multiplying by 60
- Calculate the concentration of oxytocin in the IV bag by dividing the amount of oxytocin by the volume of solution
- Divide the dosage of oxytocin by the concentration of oxytocin in the IV bag to get the volume to be delivered
Using these steps, we get:
- (dosage of oxytocin in units/hour) = (2) x (60) = 120 milliunits/hour
- (concentration of oxytocin in IV bag) = (20) / (1000) = 0.02 units/mL
- (volume to be delivered in mL/hour) = (120 x 10^-3) / (0.02) = 6 mL/hour
Therefore, the nurse should program the infusion pump to deliver 6 mL/hour of oxytocin in lactated Ringer's to the patient.
