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 ["10.2"]
Explanation
To determine the infusion rate in mL/hour for the dopamine solution:
-
Calculate the total dose per minute:
3 mcg/kg/min×91 kg=273 mcg/min3mcg/kg/min×91kg=273mcg/min. -
Convert mcg/min to mcg/hour:
273 mcg/min×60 min/hour=16,380 mcg/hour273mcg/min×60min/hour=16,380mcg/hour. -
Convert mcg to mg:
16,380 mcg÷1,000=16.38 mg/hour16,380mcg÷1,000=16.38mg/hour. -
Determine the concentration of the solution:
400 mg÷250 mL=1.6 mg/mL400mg÷250mL=1.6mg/mL. -
Calculate the mL/hour required:
16.38 mg/hour÷1.6 mg/mL=10.2375 mL/hour16.38mg/hour÷1.6mg/mL=10.2375mL/hour.
Rounded to the nearest tenth:
10.2 mL/hour.
Correct Answer is ["9000"]
Explanation
To find the answer, we can use the following steps:
- Convert the client's weight from pounds to kilograms by dividing by 2.2
- Multiply the weight in kilograms by the dosage in units/kg
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (198) / (2.2) = 90 kg
- (dose in units) = (100) x (90) = 9000 units
- (rounded dose in units) = 9000 units
Therefore, the nurse should administer 9000 units of IV Heparin to the client.
