The healthcare provider prescribes ceftazidime 30 mg/kg/day or an infant weighing 3,500 grams. What dose should the nurse administer daily to this infant? (Enter numeric value only.)
The Correct Answer is ["105"]
Given:
Ordered dose of Ceftazidime: 30 mg/kg/day
Infant's weight: 3,500 grams (3.5 kg)
Step 1: Calculate the total daily dose of Ceftazidime:
Total daily dose (mg) = Ordered dose (mg/kg/day) x Infant's weight (kg)
Total daily dose (mg) = 30 mg/kg/day x 3.5 kg
Total daily dose (mg) = 105 mg

Correct Answer is ["30"]
Explanation
Given:
Ordered dose of lamivudine: 150 mg twice daily
Concentration of lamivudine solution: 10 mg/mL
Step 1: Calculate the total daily dose of lamivudine:
Total daily dose (mg) = Dose per administration (mg) x Number of administrations per day
Total daily dose (mg) = 150 mg/dose x 2 doses/day
Total daily dose (mg) = 300 mg/day
Step 2: Calculate the volume to be administered per dose:
Volume (mL) = Dose per administration (mg) / Concentration (mg/mL)
Volume (mL) = 150 mg / 10 mg/mL
Volume (mL) = 15 mL/dose
Step 3: Calculate the total volume to be administered in 24 hours:
Total volume (mL) = Volume per dose (mL) x Number of doses per day
Total volume (mL) = 15 mL/dose x 2 doses/day
Total volume (mL) = 30 mL/day
Correct Answer is ["13"]
Explanation
Given:
Total insulin in solution: 125 units
Ordered infusion rate: 10 units/hour
Step 1: Calculate the total infusion time:
Total infusion time (hours) = Total insulin (units) / Infusion rate (units/hour)
Total infusion time (hours) = 125 units / 10 units/hour
Total infusion time (hours) = 12.5 hours
Step 2: Round to the nearest whole number:
Total infusion time (hours) ≈ 13 hours
