A nurse is caring for a client with myasthenia gravis. They have given the client a dose of 50 mg IV instead of 5 mg of pyridostigmine, an anticholinesterase drug. They notice the mistake as the client suddenly becomes dyspneic. They prepare to administer atropine sulfate 0.03 mg/kg IV. 

 If the client weighs 55 kg and the solution is at a concentration of 0.4 mg/mL, how many milliliters should they prepare? 

Record your answer to one decimal place.
