Patient with an infection X needs antibiotics. What can you do to prescribe the correct medication?

  1. Culture and sensitivity test
  2. Empirically choose the broadest spectrum antibiotic always
  3. Ask the patient which antibiotic they prefer
  4. Use the same antibiotic prescribed previously regardless of infection type
Show answer and explanation

Correct answer: A. Culture and sensitivity test

  • A. Correct. A culture and sensitivity test identifies the specific causative organism and its antibiotic susceptibility, allowing targeted, evidence-based antibiotic selection.
  • B. Defaulting to the broadest spectrum antibiotic without testing promotes antibiotic resistance and is not best practice.
  • C. Patient preference, without microbiological data, is not an evidence-based prescribing method.
  • D. Reusing a prior antibiotic without testing risks inadequate coverage for the current infection's specific organism.
