Question 1 of 5
A patient calls the clinic and reports feeling unwell, with symptoms of rapid heart rate, severe headache, and light-headedness. The nurse notes that the patient was prescribed metronidazole a few days ago. What substance could likely be causing these symptoms?
Correct Answer: C
Rationale: The correct answer is C: Alcohol. Metronidazole interacts with alcohol, causing a disulfiram-like reaction. This reaction can result in symptoms such as rapid heart rate, severe headache, and light-headedness. This is because metronidazole inhibits the breakdown of acetaldehyde, leading to an accumulation of this toxic substance when alcohol is consumed.
Choices A, B, and D do not have interactions with metronidazole that would cause these specific symptoms.
