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
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 nurse should add 250 mL of water to the formula to dilute it to half strength.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
250 mL / 1 = x mL / 0.5
Cross-multiplying and solving for x gives:
x = 500 mL
Therefore, the nurse should add 250 mL of water to the formula to make a total volume of 500 mL, which is half the concentration of the original formula.
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.
