Ati demsn maternal newborn proctored exam ( 50 Questions)
A nurse is preparing to administer acetaminophen 10 mg/kg/dose to a child who weighs 28 lb. The amount available is acetaminophen 120 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth).
Correct Answer: 5.3
Convert the child's weight from pounds (lb) to kilograms (kg)
Given weight = 28 lb
Conversion factor: 1 kg = 2.2 lb
Weight (kg) = 28 lb / 2.2 lb/kg
= 12.727 kg
Calculate the Single Dose in milligrams (mg)
Prescribed dose = 10 mg/kg/dose
Single Dose (mg) = Weight (kg) x Dose (mg/kg/dose)
= 12.727 kg x 10 mg/kg
= 127.272 mg
Calculate the Volume (mL) to Administer (Dose/Have Method)
Ordered Dose (D) = 127.272... mg
Available Dose (H) = 120 mg
Quantity (Q) = 5 mL
Volume (mL) = (Dose Ordered (D) / Dose Available (H)) x Quantity (Q)
= (127.272 mg / 120 mg) x 5 mL
= 1.0606 x 5 mL
= 5.303 mL
Round to the Nearest Tenth
= 5.3
