A nurse has to administer 0.05 mcg/kg of a medication to an infant who weighs 7 kg.
Calculate the dose that the nurse should administer to the infant.

0.35 mcg

350 mcg

35 mcg

3.5 mcg

Answer and Explanation

The Correct Answer is A

The nurse should administer 0.35 mcg of medication to the infant.

This answer is correct because it is based on a simple multiplication calculation. The nurse should multiply the prescribed dose per kilogram by the infant's weight in kilograms to get the total dose in micrograms, as follows:

0.05 mcg/kg x 7 kg = 0.35 mcg

Therefore, the nurse should administer 0.35 mcg of medication to the infant.

Correct Answer is C

Explanation

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.

A. 100 mL/hr B. 200 mL/hr C. 50 mL/hr D. 300 mL/hr

Correct Answer is B

Explanation

To find the rate in mL/hr, you need to use the formula for infusion rate:

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

Since the total volume is 50 mL, the ﬂow factor is 1 gt/mL, and the 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

Therefore, the nurse should set the IV pump to deliver **200 mL/h** to infuse Regian 10 mg over 15 minutes.
