Rationale: The correct answer is A. Common side effects of opioid analgesics include drowsiness and dizziness. These side effects can impair a person's ability to operate machinery or drive safely. To manage these side effects, it is essential to advise patients to avoid activities that require alertness until they know how the medication affects them.
