The nurse is caring for a client with a history of depression who is prescribed a selective serotonin reuptake inhibitor (SSRI). Which side effect should the nurse monitor for?

Choice A reason: Open-angle glaucoma involves chronic optic nerve damage due to impaired aqueous humor drainage, not a reversible “angle” change. Medications reduce intraocular pressure but cannot restore anatomical angles. This response is inaccurate, as the condition requires lifelong management to prevent further nerve damage and vision loss.

Choice B reason: Open-angle glaucoma requires lifelong medication to maintain normal intraocular pressure, preventing optic nerve damage. Medications like prostaglandin analogs or beta-blockers enhance aqueous humor outflow or reduce production, controlling pressure long-term. This is the accurate response, as sustained pressure management is essential to preserve vision in chronic glaucoma.

Choice C reason: Reducing excess pressure is a goal of glaucoma treatment, but open-angle glaucoma is chronic, requiring ongoing medication even after pressure is lowered. This response is incomplete, as it suggests a temporary treatment, whereas lifelong therapy is needed to prevent pressure spikes and progressive optic nerve damage.

Choice D reason: Open-angle glaucoma is typically painless and not associated with swelling. Medications target intraocular pressure, not pain or inflammation. This response is inaccurate, as it misaligns with the pathophysiology of glaucoma, which involves optic nerve damage from pressure, not inflammatory or painful symptoms.

Choice A reason: Serum creatinine assesses kidney function, not cardiac injury. While relevant for overall health, it does not confirm myocardial infarction. Troponin is specific to cardiac muscle damage, making it the priority test to diagnose acute coronary events in the emergency setting.

Choice B reason: Troponin levels are the gold standard for diagnosing myocardial infarction, as they rise within hours of cardiac muscle injury due to ischemia. High specificity for heart tissue makes troponin critical for confirming acute coronary syndrome, guiding urgent treatment in the emergency department.

Choice C reason: Complete blood count evaluates anemia or infection but is nonspecific for myocardial infarction. While useful for overall assessment, it does not detect cardiac injury. Troponin directly indicates heart muscle damage, making it the priority test for confirming the diagnosis.

Choice D reason: Blood glucose may be elevated in stress or diabetes but is not diagnostic for myocardial infarction. Cardiac-specific markers like troponin are essential for confirming heart injury, as glucose levels lack specificity for acute coronary events, making them secondary.
