A patient with scant urinary discharge is seeking treatment in the emergency room, complaining of discomfort while urinating with itchiness around the urethra. Further assessment shows thin and clear penile discharge. Tests show that the patient has a gonococcal infection. After taking the first two doses of metronidazole, the patient complained that his urine turned dark. The most appropriate response of the nurse is:
  1. “This is an unexpected response; we should report this to your doctor.”
  2. “You need to drink more water or juice to acidify your urine.”
  3. “This is an expected side effect and not clinically significant.”
  4. “This is a sign of progressing infection.”
Explanation
Answer: C - The nurse should inform the patient that metronidazole will cause his urine to turn dark. This is an expected side effect of the drug that shouldn’t alarm the patient. Options A and D are incorrect in this scenario; the patient should seek treatment if no improvement is seen in a few days or if signs of superinfections occur (e.g., white or black furry overgrowth on tongue, foul-smelling stools).
