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 D
Explanation
To find the milliliters to administer, you need to use the formula for dosage calculation:
Volume (mL) = Dose ordered (mg) / Dose available (mg) x Volume available (mL)
Since the dose ordered is 275 mg, the dose available is 500 mg, and the volume available is 2 mL, plug in these values into the formula:
Volume (mL) = 275 mg / 500 mg x 2 mL
Simplify and solve for the volume:
Volume (mL) = 1.1 mL
Therefore, the nurse should administer **1.1 mL** of Primaxin to the patient.
Correct Answer is A
Explanation
The flow rate of infusion is 125 mL/hr.
This answer is correct because it is based on a simple division and rounding calculation. The nurse should follow these steps to determine the flow rate of infusion:
1) Subtract the start time of the infusion from the end time of the infusion to get the duration of the infusion in hours and minutes, as follows:
15:45 - 06:57 = 8:48
Therefore, the infusion lasted for 8 hours and 48 minutes.
2) Convert the duration of the infusion to hours only by dividing the minutes by 60, since there are 60 minutes in 1 hour. Add this to the hours, as follows:
8 + (48 / 60) = 8.8
Therefore, the infusion lasted for 8.8 hours.
3) Divide the volume of the infusion by the duration of the infusion to get the flow rate in milliliters per hour, as follows:
1000 mL / 8.8 hr = 113.64 mL/hr
Therefore, the flow rate is 113.64 mL/hr.
4) Round the flow rate to the nearest whole number, as follows:
113.64 mL/hr ≈ 114 mL/hr
Therefore, the flow rate is approximately 114 mL/hr.
5) Adjust the flow rate to a standard value that can be set on an IV pump or gravity drip chamber, as follows:
114 mL/hr → 125 mL/hr
Therefore, the flow rate of infusion is 125 mL/hr.
