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 ["17"]
Explanation
Given:
Volume of fluid: 50 mL
Infusion time: 30 minutes
Drop factor: 10 gtt/mL
Formula:
Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL)
Step 1: Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Volume (mL) / Time (min)
Infusion rate (mL/min) = 50 mL / 30 min
Infusion rate (mL/min) = 1.67 mL/min
Step 2: Calculate the flow rate in gtt/min:
Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)
Flow rate (gtt/min) = 1.67 mL/min x 10 gtt/mL
Flow rate (gtt/min) = 16.7 gtt/min
Step 3: Round to the nearest whole number:
Flow rate (gtt/min) ≈ 17 gtt/min
Correct Answer is ["15"]
Explanation
Given:
Ordered infusion rate: 10 units/kg/hour
Patient weight: 165 pounds
Concentration of Heparin: 25,000 units in 500 mL (50 units/mL)
Step 1: Convert patient weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Patient weight in kg = 165 lbs x 0.453592 kg/lb = 74.8 kg
Step 2: Calculate the total dose of Heparin in units/hour:
Total dose (units/hour) = Ordered dose (units/kg/hour) x Patient weight (kg)
Total dose (units/hour) = 10 units/kg/hour x 74.8 kg
Total dose (units/hour) = 748 units/hour
Step 3: Calculate the infusion rate in mL/hour:
Infusion rate (mL/hour) = Total dose (units/hour) / Concentration (units/mL)
Infusion rate (mL/hour) = 748 units/hour / 50 units/mL
Infusion rate (mL/hour) = 14.96 mL/hour
Step 4: Round to the nearest whole number:
Infusion rate (mL/hour) ≈ 15 mL/hour
