The student nurse is reviewing orders given to a patient with depression. Which order should the student nurse question?

Reasoning: Choice A reason: Electroconvulsive therapy is an evidence-based intervention for patients with treatment-resistant depression or acute suicidality. It provides rapid relief of depressive symptoms when pharmacological interventions are too slow to ensure patient safety. Therefore, this is a standard and appropriate order that the nurse would not need to question. Choice B reason: Starting tricyclic antidepressants at a low dose is standard clinical practice to monitor for anticholinergic side effects and cardiotoxicity. Because these medications have a narrow therapeutic index and significant side-effect profiles, a conservative titration approach is necessary for patient safety and to improve long-term medication adherence. Choice C reason: Combining a Selective Serotonin Reuptake Inhibitor with a Monoamine Oxidase Inhibitor is strictly contraindicated due to the high risk of Serotonin Syndrome. This life-threatening condition results from excessive synaptic serotonin, leading to autonomic instability, hyperthermia, and neuromuscular abnormalities. A washout period of 2 to 5 weeks is mandatory. Choice D reason: Elavil, a tricyclic antidepressant, has sedative properties that can be utilized to manage agitation or insomnia associated with major depressive disorder. While newer agents are often preferred, it remains a valid pharmacological option in specific clinical contexts, so it does not warrant the same immediate concern as a contraindication.
