A client is receiving an intravenous infusion of 1.5 L of saline solution at a rate of 75 mL/hr.
How many hours will it take to finish the infusion at the current rate?
10 hours
7.5 hours
20 hours
15 hours
The Correct Answer is C
To find the hours to finish the infusion, you need to calculate the following:
- The volume of saline solution in milliliters
- The time in hours using the formula: Time (h) = Total volume (mL) / Infusion rate (mL/h)
First, convert the volume of saline solution from liters to milliliters by multiplying by 1000:
1.5 L x 1000 = 1500 mL
Next, use the formula for time to find how many hours it will take to infuse the saline solution at the current rate:
Time (h) = Total volume (mL) / Infusion rate (mL/h)
Since the total volume is 1500 mL and the infusion rate is 75 mL/h, plug in these values into the formula:
Time (h) = 1500 mL / 75 mL/h
Simplify and solve for the time:
Time (h) = 20 h
Therefore, it will take **20 hours** to finish the infusion at the current rate.

Correct Answer is B
Explanation
The nurse should administer 1050 mg of medication to achieve the total prescribed dose.
This answer is correct because it is based on a simple multiplication calculation. The nurse can multiply the prescribed dose per kilogram by the weight of the client in kilograms to get the total dose in milligrams, as follows:
25 mg/kg x 42 kg = 1050 mg
Therefore, the nurse should administer 1050 mg of medication to the client.
Correct Answer is D
Explanation
The nurse should administer 2 tablets per dose to this patient.
This answer is correct because it is based on a simple unit conversion and ratio and proportion calculation. The nurse can convert 0.1 mg to 100 mcg by multiplying by 1000, since there are 1000 mcg in 1 mg. Then, the nurse can set up a proportion as follows:
50 mcg / 1 tablet = 100 mcg / x tablets
Cross-multiplying and solving for x gives:
x = 2 tablets
Therefore, the nurse should administer 2 tablets of Synthroid to deliver 0.1 mg or 100 mcg of the medication to the patient.
