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
- Ordered dose = 1.0 mg
- Available concentration = 0.4 mg per 1 mL
Step 2: Use the ratio and proportion method
Required dose ÷ Available concentration = Volume to administer
Step 3: Plug in the values
= (1.0 ÷ 0.4)
Step 4: Solve step by step
- 1.0 ÷ 0.4 = 2.5 mL
Step 5: Round to the nearest tenth
- 2.5 mL (already rounded)
Correct Answer is B
Explanation
To solve this problem, we need to use the formula:
Desired dose / Available dose = Number of tablets
Plugging in the given values, we get:
200 mg / 100 mg = Number of tablets
2 = Number of tablets
Therefore, the correct dosage is 2 tablets.
