A nurse is administering an intravenous (IV) infusion of 2 g cefotaxime dissolved in 100 mL of isotonic glucose solution to a client. The drop factor of the IV tubing is 15 drops/mL.
If the infusion time is 1 hr, what is the gt/min?
400 gt/min
6 gt/min
25 gt/min
9 gt/min
The Correct Answer is C
The gt/min is 25.
This answer is correct because it is based on a simple formula and calculation. The nurse should use the following formula to calculate the gt/min:
gt/min = (Volume in mL x Drop factor in gt/mL) / Time in min
Plugging in the given values, the nurse should get:
gt/min = (100 mL x 15 gt/mL) / 60 min
gt/min = 25
Therefore, the gt/min is 25.

Correct Answer is D
Explanation
To answer this question, we need to calculate the infusion rate in mL per hour by using the following formula²:
Infusion rate (mL/h) = Dose (mcg/kg/min) × Weight (kg) × 60 min/h × Volume (mL) / Concentration (mcg/mL)
In this case, the infusion rate is:
Infusion rate (mL/h) = 3 mcg/kg/min × 70 kg × 60 min/h × 250 mL / 2500 mg
We need to convert lb to kg by dividing by 2.2
Infusion rate (mL/h) = 3 mcg/kg/min × (154 lb / 2.2 kg/lb) × 60 min/h × 250 mL / 2500 mg
We need to convert mg to mcg by multiplying by 1000:
Infusion rte (mL/h) = 3 mcg/kg/min × (154 lb / 2.2 kg/lb) × 60 min/h × 250 mL / (2500 mg × 1000 mcg/mg)
We can simplify the equation by canceling out some units and numbers:
Infusion rate (mL/h) = 3 × 154 × 250 / (2.2 × 2500 × 1000)
We can use a calculator to get the final answer:
Infusion rate (mL/h) = 12.6363636363636 mL/h
Correct Answer is D
Explanation
One tablespoon is equal to **14.7867648 milliliters**¹²³⁴. To convert tablespoons to milliliters, you can multiply the value in tablespoons by 14.7867648. For example, 1 tablespoon x 14.7867648 milliliters = 14.7867648 milliliters.
Therefore, to convert 1 tablespoon of mouthwash to milliliters, you can multiply 1 by 14.7867648. The answer is **14.7867648 milliliters**. This is the amount of mouthwash that a patient uses in 1 tablespoon.
