Available: Acetaminophen elixir 120 mg/10ml

Answer 1

Ordered dose of Acetaminophen elixir is 180 mg PO q6h

1mg of Acetaminophen elixir will be available in 10/120ml of solution

Then 180mg of Acetaminophen elixir will be available in 10/120×180ml

= 15ml of the available solution of Acetaminophen elixir should be given to the patient
