Calculate the flow rate in mL/hr. (Equipment used is programmable in whole mL/hr). Order: 2,000 mL D5W in 24 hr by infusion pump. Calculate rate in mL/hr.
83 mL/hr
75 mL/hr
42 mL/hr
60 mL/hr
The Correct Answer is A
Step 1: Identify the total volume to be infused.
- Total volume = 2,000 mL
Step 2: Identify the total time for infusion.
- Total time = 24 hours
Step 3: Calculate the flow rate in mL/hr.
- Flow rate = Total volume ÷ Total time
- Flow rate = 2,000 mL ÷ 24 hours
Step 4: Perform the division.
- 2,000 ÷ 24 = 83.3333…
Step 5: Round to the nearest whole number since the equipment is programmable in whole mL/hr.
- Rounded flow rate = 83 mL/hr
So, the flow rate is 83 mL/hr.

Correct Answer is C
Explanation
Step 1: Identify the given information
- Total volume to infuse = 100 mL
- Infusion time = 30 minutes
- Drop factor = 60 gtt/mL
Step 2: Use the formula for flow rate
Flow rate (gtt/min) = (Total Volume (mL) × Drop Factor (gtt/mL)) ÷ Infusion Time (min)
Step 3: Plug in the values
= (100 × 60) ÷ 30
Step 4: Solve step by step
- 100 × 60 = 6000
- 6000 ÷ 30 = 200
Correct Answer is B
Explanation
To solve this problem, we need to use the formula:
Rate (mL/hr) = Volume (mL) / Time (hr)
Plugging in the given values, we get:
Rate (mL/hr) = 100 mL / 0.75 hr
Rate (mL/hr) = 133.33 mL/hr
However, this is not the final answer because the equipment used is programmable in whole mL/hr, which means we need to round the rate to the nearest whole number. Therefore, we need to apply the rounding rule: if the decimal part is 0.5 or more, round up; if the decimal part is less than 0.5, round down. In this case, the decimal part is 0.33, which is less than 0.5, so we round down. This gives:
Rounded rate (mL/hr) = 133 mL/hr
Therefore, the correct flow rate is 133 mL/hr.
