A toxic reaction to local anesthesia can cause which condition?

  1. Hypertension

  2. Bradycardia

  3. Hypotension

  4. Tachycardia

The correct answer is: Hypotension

A toxic reaction to local anesthesia can cause hypotension, which is a sudden and potentially dangerous drop in blood pressure. This is due to the medication's effect on the cardiovascular system, specifically the blood vessels. Option A, hypertension or high blood pressure, and option B, bradycardia or slow heart rate, are opposite reactions to hypotension and can be ruled out. Option D, tachycardia or fast heart rate, is not typically associated with a toxic reaction to local anesthesia. Therefore, option C is the correct answer. However, it is important to note that any severe or abnormal reaction to a medication should be immediately reported to a healthcare professional.
