A 9-year-old child who weighs 66 lb is to receive gentamicin sulfate 2 mg/kg/dose every 8 hours for an Escherichia coli urinary tract infection. How many mg per dose should this child receive? (Enter numeric value only.)
The Correct Answer is ["60"]
Here's how to calculate the gentamicin dosage per dose for the child:
Client weight conversion:
Client weight: 66 lbs
We need the weight in kilograms (kg) for the medication dosage.
Conversion factor: 1 kg = 2.205 lbs
Client weight (kg) = 66 lbs / 2.205 lbs/kg = 30 kg (round to nearest whole number)
Gentamicin dosage:
Prescribed dose: 2 mg/kg/dose (given)
Calculate the total gentamicin amount per dose:
Total dose (mg/dose) = Dose (mg/kg/dose) x Client weight (kg)
Total dose (mg/dose) = 2 mg/kg/dose * 30 kg
Total dose (mg/dose) = 60 mg (round to nearest whole number)
Therefore, the child should receive 60 mg of gentamicin sulfate per dose.

Correct Answer is ["111"]
Explanation
Here's how to calculate the rate for the infusion pump:
Total volume to infuse: 1 liter (given)
Infusion time: 9 hours (given)
We need to find the volume delivered per hour (mL/hour) considering the total volume and infusion time.
Volume conversion: Since the volume is given in liters, convert it to mL:
1 liter * 1000 mL/liter = 1000 mL
Infusion rate (mL/hour):
Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours)
Infusion rate (mL/hour) = 1000 mL / 9 hours
Infusion rate (mL/hour) = 111.11 mL/hour (round to nearest tenth)
Therefore, the nurse should program the infusion pump to deliver approximately 111 mL/hour.
Correct Answer is ["4.8"]
Explanation
The vial is labeled as “100 mg per 4 mL.”
This means that each mL contains 25 mg of the medication (100 mg / 4 mL = 25 mg/mL).
The nurse needs to administer 120 mg of the medication.
To find out how many mL this is, we divide the dose by the concentration:
VolumeinmL = 120mg / 25mg/mL = 4.8mL
If rounding is required to the nearest tenth, the nurse should administer 4.8 mL of the medication.
