Which statement about narcotic analgesics is true?

• A. They increase concentration
• B. They enhance athletic performance
• C. They improve coordination
• D. They depress the central nervous system to give relief from painful injuries

Answer: (D)

Narcotic analgesics relieve pain by depressing the central nervous system, which reduces how pain is perceived and how the brain responds to painful injuries. They work by binding to opioid receptors in the brain and spinal cord, dampening the transmission of pain signals and often producing a sense of relief alongside sedation. Because this CNS depression can slow thinking, dull reflexes, and impair coordination, these drugs typically don’t improve concentration, coordination, or athletic performance; they can actually hinder performance. That’s why the statement describing them as depressing the CNS to provide relief from painful injuries is true.
