Determine the desired dose per administration.
The nurse needs to administer 150 mg of lamivudine per dose.

The nurse is preparing to administer 100 mL of ceftriaxone sodium in dextrose 5% in water.
Calculate the infusion rate in mL/hr.
The infusion time is 30 minutes, which is equivalent to 30/60 = 0.5 hours.
Infusion rate = Total volume / Infusion time = 100 mL / 0.5 hr = 200 mL/hr
Correct Answer is ["165"]
Explanation
Convert the patient's weight to kg.
The patient weighs 245 lb.
1 lb is approximately equal to 0.45 kg.
Patient's weight in kg = 245 lb x 0.45 kg/lb = 110.25 kg
Calculate the dose per administration.
The prescribed dose is 1.5 mg/kg/dose.
Dose per administration = 1.5 mg/kg/dose x 110.25 kg = 165.375 mg/dose
Round the dose to the nearest whole number.
Dose per administration = 165 mg
