Your friend Porter believes that if he visits the doctor, he should get a prescription. More specifically, he believes that if he has an infection, whether due to an ingrown toenail, a cold, or something more serious, he should get an oral antibiotic. He reasons that he is the one taking the risk of adverse effects, so it should be his choice. Is he right?
 A) Porter is right only if the infection is caused by bacteria. A virus should be treated with an antiviral.
  B) No. While a minor infection, such an ingrown toenail, may be treated topically, all other infections should be treated with antibiotics.
  C) No. The overuse of antibiotics leads to the development of resistance, which puts everyone at risk.
  D) Yes. In general, Porter is right about this.
