Your patient is a 19-year-old female who called EMS because she awoke with itchy red patches on her chest, back, and arms that seem to come and go. As you obtain the history, you learn that she started taking Keflex, an antibiotic, two days ago to prevent infection in a laceration to her hand. In explaining to your patient what is going on, which of the following statements would be the most accurate?
A) It looks like the infection in your hand has spread to the bloodstream. The toxins from the bacteria are causing a rash.
B) These look like hives. They occur during an allergic reaction. You may have developed an allergy to the antibiotic you are taking.
