Question

The practical nurse (PN) is preparing to administer terbutaline 25 mcg/kg/dose subcutaneously to a client with emphysema who weighs 80pounds. The available concentration is 1 mg/1 ml. How many mL should the PN administer? (Enter numeric value only. If rounding isrequired, round to the nearest fenth.)

Answer 1

We have the following:

The first thing is to calculate how many mcg for an 80 pound person.

We know that

1 kg = 2.2 pounds

80 pounds * 1 kg/ 2.2 pounds = 36.3 kg

now,

now,

1 mcg = 0.001 mg

therefore:

`915\text{mcg}\cdot\frac{0.001mg}{\text{mcg}}=0.915mg`

the milligram per milliliter ratio is 1 to 1, therefore 0.915 milliters is the correct answer
