A nurse is preparing to administer cefotaxime 100 mg/kg /IV bolus divided in equal doses every 8 hr to a toddler who weighs 26.4 lb. Available is cefotaxime injection 300 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.3"]
Order: Cefotaxime 100 mg/kg IV bolus, divided into equal doses every 8 hours
Toddler Weight: 26.4 lb
Available Solution: Cefotaxime injection 300 mg/mL
Desired Dose: mL per dose
Step 1: Convert Toddler Weight to Kilograms (kg)
1 kg = 2.2 lbs
Toddler Weight in kg: 26.4 lbs / 2.2 lbs/kg = 12 kg
Step 2: Calculate the Total Daily Dose
Ordered Dose: 100 mg/kg
Toddler Weight: 12 kg
Total Daily Dose: 100 mg/kg x 12 kg = 1200 mg
Step 3: Determine the Number of Doses per Day
Doses are given every 8 hours.
Hours in a Day: 24 hours
Number of Doses: 24 hours / 8 hours/dose = 3 doses
Step 4: Calculate the Dose per Administration
Total Daily Dose: 1200 mg
Number of Doses: 3
Dose per Administration: 1200 mg / 3 doses = 400 mg/dose
Step 5: Calculate the Volume to Administer per Dose
Dose per Administration: 400 mg
Concentration: 300 mg/mL
Volume to Administer: 400 mg / 300 mg/mL = 1.333 mL
Step 6: Round to the Nearest Tenth
The calculated volume is 1.333 mL.
Rounded to the nearest tenth: 1.3 mL
Answer: 1.3 mL

Explanation
Order: Dexamethasone 0.5 mg/kg/day IM, divided equally every 6 hours
Client Weight: 132 lbs
Available Solution: Dexamethasone 4 mg/mL
Desired Dose: mL per dose
Step 1: Convert Client Weight to Kilograms (kg)
1 kg = 2.2 lbs
Client Weight in kg: 132 lbs / 2.2 lbs/kg = 60 kg
Step 2: Calculate the Total Daily Dose
Ordered Dose: 0.5 mg/kg/day
Client Weight: 60 kg
Total Daily Dose: 0.5 mg/kg/day x 60 kg = 30 mg/day
Step 3: Determine the Number of Doses per Day
Doses are given every 6 hours.
Hours in a Day: 24 hours
Number of Doses: 24 hours / 6 hours/dose = 4 doses
Step 4: Calculate the Dose per Administration
Total Daily Dose: 30 mg/day
Number of Doses: 4 doses
Dose per Administration: 30 mg / 4 doses = 7.5 mg/dose
Step 5: Calculate the Volume to Administer per Dose
Dose per Administration: 7.5 mg
Concentration: 4 mg/mL
Volume to Administer: 7.5 mg / 4 mg/mL = 1.875 mL
Step 6: Round to the Nearest Tenth
The calculated volume is 1.875 mL.
Rounded to the nearest tenth: 1.9 mL
Answer: 1.9 mL
Correct Answer is ["4.5"]
Explanation
Calculate the Insulin Dose in Units/hr:
Dose = 0.1 units/kg/hr x 45 kg
Dose = 4.5 units/hr
Determine the Insulin Concentration in Units/mL:
Available concentration = 1 unit/mL (given in the problem)
Calculate the Infusion Rate in mL/hr:
Infusion Rate (mL/hr) = Dose in units/hr / Concentration (units/mL)
Infusion Rate (mL/hr) = 4.5 units/hr / 1 unit/mL
Infusion Rate (mL/hr) = 4.5 mL/hr
Round to the Nearest Tenth (if necessary):
4.5 mL/hr
