A client is prescribed 25 mg/kg of a medication. The weight of the client is 42 kg.
How many milligrams (mg) of medication should be administered to achieve the total prescribed dose?
1250 mg
1150 mg
950 mg
1050 mg
The Correct Answer is B
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.

Correct Answer is C
Explanation
The nurse should administer 12.5 mL of amoxicillin oral suspension.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
200 mg / 5 mL = 500 mg / x mL
Cross-multiplying and solving for x gives:
x = 12.5 mL
Therefore, the nurse should administer 12.5 mL of amoxicillin oral suspension to deliver 500 mg of the medication to the patient.
Correct Answer is A
Explanation
The amount of ampicillin in one dose is 390 mg.
This answer is correct because it is based on a series of multiplication and division calculations. The nurse should follow these steps to determine the amount of ampicillin in one dose:
1) Multiply the prescribed dose per kilogram per day by the child's weight in kilograms to get the total dose per day in milligrams, as follows:
150 mg/kg/day x 10.4 kg = 1560 mg/day
Therefore, the child needs 1560 mg of ampicillin per day.
2) Divide the total dose per day by the number of doses per day to get the amount of each dose in milligrams, as follows:
1560 mg/day / 4 doses/day = 390 mg/dose
Therefore, the amount of ampicillin in one dose is 390 mg.
