Final answer:
Side effects of a drug are typically experienced in the same nervous system where the drug acts, and a drug affecting both divisions of the autonomic nervous system likely targets nicotinic receptors.
Step-by-step explanation:
If you know what a particular drug does, you should choose a side effect in the same nervous system where the drug is working. The options provided refer to various body systems, but the relevant systems for this context are the autonomic nervous system and the subdivisions therein—the sympathetic and parasympathetic systems.
A drug that affects both divisions of the autonomic nervous system is going to bind to or block which type of neurotransmitter receptor? The correct answer is nicotinic receptors, which are found in both the sympathetic and parasympathetic nervous systems. Muscarinic, α-adrenergic, and ß-adrenergic receptors are also present in the autonomic nervous system, but they are more specific to either the sympathetic or parasympathetic division or are involved in specific signaling mechanisms.
Psychoactive drugs often have significant negative side effects, and individuals vary dramatically in how they respond to the drugs. Side effects should therefore be anticipated within the same nervous system on which the drug acts.
