ATI Dosage Calculations RN Nursing Care of Children 3.1 ( 28 Questions)
A nurse is preparing to administer diazepam 0.3 mg/kg IV bolus to a toddler who weighs 24 Ib. Available is diazepam injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.65 mL
Let’s calculate this step by step:
Step 1: Convert the toddler’s weight from pounds (lb) to kilograms (kg) using the conversion factor 1 kg = 2.2 lbs.
24 lbs ÷ 2.2 lbs/kg = 10.91 kg
Step 2: Calculate the total amount of diazepam needed using the dosage of 0.3 mg/kg.
0.3 mg/kg × 10.91 kg = 3.27 mg
Step 3: Calculate the volume of diazepam injection to administer using the concentration of 5 mg/mL.
3.27 mg ÷ 5 mg/mL = 0.654 mL
Rounding to the nearest hundredth, the nurse should administer 0.65 mL of diazepam injection.
