Drugs for Peripheral Nervous System Questions
Question 1 of 5
What is the major mechanism of action of the drug that apparently caused the patient's signs and symptoms?
Correct Answer: A
Rationale: The correct answer is A: Inhibition of transmitter reuptake at noradrenergic synapses. This mechanism of action is consistent with symptoms related to increased noradrenergic activity. By inhibiting reuptake, more neurotransmitter remains in the synaptic cleft, leading to increased stimulation of postsynaptic receptors. Options B, C, and D do not directly relate to the patient's signs and symptoms, which are likely due to excess noradrenergic activity. Option B, activation of opiate receptors, would not explain the symptoms. Option C, activation of serotonergic presynaptic receptors, is not relevant to noradrenergic activity. Option D, stimulation of monoamine release, is less likely as the symptoms are more indicative of increased noradrenaline levels due to reuptake inhibition.
