How to solve this: a small dog has consumed a dangerous amount of apap. the vet has ordered: rx acetylcysteine 150mg/kg/stat. your stock solution of acetylcysteine is 20%. how many ml will this 13.2lb. dog need for this dose?

a. 4.5ml

b. 10ml

c. 26.4ml

d. none of the above?

Given:

Stock dose/concentration of 20% Acetylcysteine (200 mg/mL)

150 mg/kg dose of Acetylcysteine

Weight of the dog is 13.2 lb

First we must convert 13.2 lb to kg:

13.2 lb / (2.2kg/lb) = 6 kg

Then we must calculate the dose:

(150 mg/kg) (6kg) = 900 mg

Lastly, we must calculate the dose in liquid form to be administered:

(900 mg) / (200 mg/mL) = 4.5 mL

Therefore, 4.5 mL of 20% Acetylcysteine should be given.
