Opioids (narcotics) have what effect?

• A. Cause dehydration
• B. Induce sleep only
• C. Treat infections
• D. Relieve pain and produce euphoria

Answer: (D)

Opioids act on receptors in the brain and spinal cord to block pain signals, giving analgesia. They also commonly produce a feeling of euphoria, which is a mood-altering effect. This combination—relieving pain and creating a sense of well-being—is why opioids are known for their analgesic and mood-changing properties. They do not have a primary role in dehydration or treating infections. While they can cause drowsiness or sedation, they are not limited to inducing sleep, and they carry risks such as respiratory depression and constipation. In practice, this dual effect explains both their therapeutic use for pain and their potential for misuse or overdose, so monitoring respiration, level of consciousness, and pain relief is essential.
