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, then multiply it by the total time in hours, and finally divide it by 1000 to get the volume in litres.
The infusion rate in mL per hour is the amount of fluid that is given to a patient over a period of time. It can be calculated by dividing the total volume of fluid in mL by the total time in hours². In this case, the infusion rate is:
2.75 mL/min × 60 min/h = 165 mL/h
The total volume of fluid in mL is the infusion rate multiplied by the total time in hours. In this case, the total volume is:
165 mL/h × 7 h = 1155 mL
The volume in litres is the volume in mL divided by 1000. In this case, the volume in litres is:
1155 mL / 1000 = 1.16 L
Therefore, the correct answer is d. 1.16 L.
Correct Answer is B
Explanation
To find the milliliters per dose, you need to use the formula for dosage calculation:
Volume (mL) = Dose ordered (mg) / Concentration (mg/mL) x Volume available (mL)
Since the dose ordered is 0.5 grams, the concentration is 125 mg/5 mL, and the volume available is 5 mL, plug in these values into the formula:
Volume (mL) = 0.5 grams / 125 mg/5 mL x 5 mL
However, before you can simplify and solve for the volume, you need to convert the dose from grams to milligrams by multiplying by 1000:
Volume (mL) = 500 mg / 125 mg/5 mL x 5 m
Simplify and solve for the volume:
Volume (mL) = 20 mL
Therefore, the nurse should administer **20 mL** of Amoxil per dose to the patient.
