Case Study Answer: Kreiyln had mentioned she took over the counter cold medicine, but it
hasn’t been helping her. She probably doesn’t have a cold because antibiotics don’t work on
colds due to their protective layer and she probably has something else which led the doctor to
further investigate what it is because she said the medicine wasn’t helping. Another thing is that
colds usually don't lead up to feelings of fatigue which could’ve also made the doctor guess it
isn’t a cold.
