I'm thinking 8.07 mL/dose??

Can't get this one either:

Order: Dynapen 100 mg every 6 hours orally.

Weight of child: 71 lbs.

Drug manufacturer recommendations: 12.5 mg/kg/day divided into 4 doses.

Supply: Dynapen 62.5 mg/5 mL.

How many mL will the nurse administer?

order: dynapen 100 mg every 6 hours orally.

weight of child: 71 lbs.

drug manufacturer recommendations: 12.5 mg/kg/day divided into 4 doses.

supply: dynapen 62.5 mg/5 ml.

how many ml will the nurse administer?

first you need to determine what one manufacture's recommended dose will be for this child. it involves converting the child's weight to kg, so you must know that 2.2 pounds = 1 kg:

12.5 mg

(dose desired)

/4 doses

(in a 24 hour day)

x 71 pounds

(weight of child)

/2.2 pounds

(to convert child's weight to kg)

= 100.85227 mg

, rounded off to

101 mg

you determine that the doctor has ordered a safe dose.

now, you can determine the ml to give based on what the doctor ordered:

100 mg

(dose desired)

/62.5 mg

(dose on hand)

x 5 ml

(amount the dose on hand comes in)

=

8 ml

(amount to give)
