A nurse is educating a client about a new prescription for morphine sulfate (Astramorph). Which of the following statement should the nurse include in the teaching about morphine?
Morphine sulfate acts as an antagonist on the mu and kappa receptors.
Morphine sulfate acts as an agonist on the mu and kappa receptors
Morphine sulfate has a less analgesic effect compared to butorphanol.
Morphine sulfate has a low potential for abuse, causing little euphoria.
The Correct Answer is B
A. Morphine is an opioid agonist, not an antagonist. It binds to the mu and kappa receptors to produce its analgesic effects.
B. Morphine sulfate is an opioid analgesic that works by binding to the mu and kappa receptors in the brain and spinal cord, which produces pain relief.
C. This statement is not accurate. Morphine sulfate typically has a stronger analgesic effect than butorphanol, a partial opioid agonist.
D. Morphine sulfate has a high potential for abuse due to its euphoric effects and is classified as a controlled substance.
