The patient is a 5-day-old newborn who weighs 7 lb 3 oz. Ordered: Nebcin 4 mg IM q12h. Refer to information from package insert. If this is a safe dose, calculate the amount to administer: ________ If it is not a safe dose, write: not safe. 
Fill in the blank(s) with the appropriate word(s).
0.4 mL
Convert weight to kg:
1 lb : 16 oz = x : 3 oz
x = 0.1875, rounded to 0.2 lb
1 kg : 2.2 lb = x : 7.2 lb 
x = 3.267 kg, rounded to 3.3 kg
Calculate maximum safe dose:
D = 4 mg/kg × 3.3 kg
D = 13.2 mg
13.2 given in 2 divided doses = 6.6 mg/dose = maximum safe dose.
Therefore, 4 mg is a safe dose.
Calculate amount to administer:
H = 20 mg; Q = 2 mL; D = 4 mg 
A = 0.4 mL
