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 ["0.25"]
Explanation
Given:
Ordered dose of Epinephrine: 0.01 mg/kg
Child's weight: 55 pounds
Concentration of Epinephrine: 1 mg/mL
Step 1: Convert child's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Child's weight in kg = 55 lbs x 0.453592 kg/lb = 24.94756 kg
Step 2: Calculate the total dose of Epinephrine:
Total dose (mg) = Ordered dose (mg/kg) x Child's weight (kg)
Total dose (mg) = 0.01 mg/kg x 24.94756 kg
Total dose (mg) = 0.2494756 mg
Step 3: Calculate the volume to be administered:
Volume (mL) = Total dose (mg) / Concentration (mg/mL)
Volume (mL) = 0.2494756 mg / 1 mg/mL
Volume (mL) = 0.2494756 mL
Step 4: Round to the nearest hundredth:
Volume (mL) ≈ 0.25 mL
Correct Answer is ["0.8"]
Explanation
Given:
Ordered dose of phenytoin: 20 mg
Concentration of phenytoin suspension: 125 mg/5 mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
20 mg / Volume = 125 mg/5 mL
Step 3: Solve for the unknown volume:
Volume = 20 mg / (125 mg/5 mL)
Volume = 20 mg x (5 mL / 125 mg)
Volume = 0.8 mL
