Physiological AdaptationQuestion 1457 of 2368

A client develops oral thrush after taking antibiotics. Which explanation should the nurse understand?

  1. The antibiotics were contaminated with fungus during manufacturing
  2. The antibiotics stopped white blood cell production in the bone marrow
  3. The antibiotics killed bacteria that normally keep Candida growth in check
  4. The antibiotics removed the protective mucus layer from the mouth and throat
Show answer

Correct answer: The antibiotics killed bacteria that normally keep Candida growth in check

Normal flora bacteria limit Candida. When antibiotics kill them, the yeast can overgrow and cause thrush.
