Step-by-step explanation:
The possible side effects of narcotic analgesics include constipation, respiratory depression, and nausea. Therefore, the correct answer is d. All of the above. Narcotic analgesics act on the central nervous system to relieve pain, but can also lead to various side effects. When taken in higher doses, these drugs can cause drowsiness and, potentially, loss of consciousness. It is important for individuals taking narcotic analgesics to be aware of these side effects and to use them under proper medical supervision to minimize risks.
