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?

A.

400 gt/min

B.

6 gt/min

C.

25 gt/min

D.

9 gt/min

Answer and Explanation

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 B

Explanation

This is another dosage calculation problem. To solve it, we need to use the formula:

Caloric need ÷ Calories per mL 1000 = Formula per day

In this case, the caloric need is 2250 calories, and the calories per mL is 2000/1000 = 2. Plugging these values into the formula, we get:

2250 ÷ 2 × 1000 = 1125

Therefore, the client would need **1125 mL** of formula per day to meet the calorie requirements.

Correct Answer is A

Explanation

To set the IV pump correctly, you need to calculate the following:

  • The patient's weight in kilograms
  • The dose of Zofran in milligrams
  • The infusion rate in milliliters per hour

First, convert the patient's weight from pounds to kilograms by dividing by 2.2:

176 lb / 2.2 = 80 kg

Next, multiply the patient's weight by the dose of Zofran per kilogram to get the total dose in milligrams:

80 kg x 0.15 mg/kg = 12 mg

Then, use the formula for infusion rate to find how many milliliters per hour the IV pump should deliver:

Infusion rate (mL/h) = (Total volume (mL) x Flow factor (gt/mL)) / Time (min) x 60 min/h

Since the medication is mixed in 50 mL of normal saline and the infusion time is 15 minutes, plug in these values into the formula:

Infusion rate (mL/h) = (50 mL x 1 gt/mL) / 15 min x 60 min/h

Simplify and solve for the infusion rate:

Infusion rate (mL/h) = 200 mL/h
