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 ["100"]
Explanation
Given:
Volume of fluid: 2 liters (1 liter = 1000 mL, so 2 liters = 2000 mL)
Infusion time: 20 hours
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 2000 mL / 20 hr
Flow rate (mL/hr) = 100 mL/hr
Correct Answer is ["6"]
Explanation
Given:
Ordered dose of Oxytocin: 2 milliunits/min
Concentration of Oxytocin: 20 units in 1 liter (1000 mL) = 20 units/1000 mL = 0.02 units/mL
Step 1: Convert milliunits to units:
Ordered dose (units/min) = Ordered dose (milliunits/min) / 1000 milliunits/unit
Ordered dose (units/min) = 2 milliunits/min / 1000 milliunits/unit
Ordered dose (units/min) = 0.002 units/min
Step 2: Calculate the infusion rate in units/hour:
Infusion rate (units/hour) = Ordered dose (units/min) x 60 minutes/hour
Infusion rate (units/hour) = 0.002 units/min x 60 minutes/hour
Infusion rate (units/hour) = 0.12 units/hour
Step 3: Calculate the infusion rate in mL/hour:
Infusion rate (mL/hour) = Infusion rate (units/hour) / Concentration (units/mL)
Infusion rate (mL/hour) = 0.12 units/hour / 0.02 units/mL
Infusion rate (mL/hour) = 6 mL/hour
