A client presents with symptoms of chest pain, irritability, and restlessness. Which listed medication's adverse effects present similarly?

Choice A reason: Bupropion is a norepinephrine-dopamine reuptake inhibitor that can exert significant sympathomimetic effects on the central nervous system. Common adverse reactions include dose-related agitation, irritability, and restlessness due to increased dopaminergic signaling. Furthermore, bupropion is associated with cardiovascular side effects such as tachycardia and hypertension, which may manifest clinically as chest pain or palpitations in sensitive patients. Choice B reason: Zolpidem is a non-benzodiazepine hypnotic that acts as a GABA-A receptor agonist to induce sedation and sleep. Its primary side effects are central nervous system depression, dizziness, and parasomnias, such as sleep-walking. It does not typically cause sympathomimetic activation, chest pain, or irritability; in fact, its pharmacological profile is intended to reduce restlessness to facilitate sleep onset. Choice C reason: Sertraline is a selective serotonin reuptake inhibitor that more commonly causes gastrointestinal distress, sexual dysfunction, or initial transient anxiety. While "activation syndrome" can occur early in treatment, it is less characteristically associated with acute chest pain compared to the noradrenergic stimulation of bupropion. Bupropion’s unique mechanism makes it a more likely culprit for this specific constellation of symptoms. Choice D reason: Glargine insulin is a long-acting basal insulin used for glycemic control in diabetes mellitus. Its primary adverse effect is hypoglycemia, which can cause irritability and restlessness; however, the classic triad including chest pain is more indicative of the stimulant-like profile of bupropion. Insulin does not directly stimulate the noradrenergic system to the degree that psychiatric stimulants or certain antidepressants do.
