Answer 1

0.75 ml is required to administer a 75 mcg dose

Step-by-step explanation:

Given :

Lanoxin concentration = 0.1 mg/ml

Dose = 75 mcg

To Find:

mL required to administer the given dose

Solution

DESCRIPTION

LANOXIN (digoxin) is an cardiac glycoside, a group of drugs with specific common effects on myocardium. These are drugs that are found in plants. It is obtained from the Digitalis lanata leaves.

mL required to administer the given dose

Where

1 mg = 1000 mcg

75 mcg = 0.075 mg

So,

ml = 0.075 mg/ 0.1 mg/ml

Hence, to administer a 75 mcg dose we require 0.75 ml.
