Question 5 of 5
Which of the following molecular actions most likely mediated the analgesic effect of morphine in the patient with multiple fractures?
Correct Answer: D
Rationale: The opening of K+ channels on postsynaptic neurons is a key molecular action that mediates the analgesic effect of opioids like morphine. This action leads to hyperpolarization of the neuron, reducing its excitability and inhibiting pain transmission. Therefore, in a patient with severe pain due to multiple fractures, the opening of K+ channels by morphine would be the most likely mechanism responsible for the analgesic effect.
