A nurse is teаching а client аbоut the difference between PRN albuterоl use and the develоpment of tolerance/worsening asthma control. The client states, "I've been using my albuterol inhaler 4-5 times every day for the past two weeks, but it doesn't seem to help as much anymore, so I just use it more often." Which response by the nurse is MOST appropriate?
