Propranolol is administered by IV for life-threatening arrhythmias. The maximum daily dose is 3 mg. If the solution of propranolol has a concentration of 0.06 mg/ml, how many milliliters are required to administer a maximum dose?

ANSWER:

50milliliters(mls) of propanolol solution will be required to achieve

the maximum dose of 3mg.

EXPLANATION:

If the concentration of propanolol solution is 0.06mg/ml, it means that 0.06 milligrams(mg) is in 1 milliliter and therefore 3 mg will be in x milliliters(mls).

That is:

0.06 mg = 1 ml

3 mg = x mls

CROSS MULTIPLY both equations to solve for x :-

0.06x = 1 X 3

Therefore x = (1 X 3)/ 0.06

x = 3/0.06 which means that:

x = 50 mls

50mls is needed to achieve the maximum dose of 3mg

Explanation:If a ml contain 0.06mg

Then; 1ml=0.06mg

Xml = 3mg

X = 3*1 ÷0.06mg

X= 50ml

0.06mg=1ml

3mg=x

X= 3mgx1ml/0.06mg

=3ml/0.06

=50mls

50mls will be required to administer a maximum dose.
