The nurse is caring for a client with a history of chronic obstructive pulmonary disease who is receiving oxygen therapy. Which assessment should the nurse prioritize?

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: Neutropenia, a low neutrophil count, is a common chemotherapy side effect due to bone marrow suppression, increasing infection risk. Monitoring neutrophil counts is critical, as infections in breast cancer patients can be life-threatening, making it the priority side effect to assess.

Choice B reason: Hypertension is not a typical chemotherapy side effect, though some agents cause cardiovascular effects. Neutropenia is more common, compromising immunity, making it the priority to monitor, as infections pose an immediate threat in breast cancer patients on chemotherapy.

Choice C reason: Hyperkalemia is rare with chemotherapy, except in tumor lysis syndrome. Neutropenia is a frequent side effect, increasing infection risk due to marrow suppression, making it the priority to monitor, as it directly impacts patient safety during breast cancer treatment.

Choice D reason: Weight gain is not a primary chemotherapy side effect; weight loss is more common due to nausea. Neutropenia is critical to monitor, as low neutrophils increase infection risk, requiring urgent intervention in breast cancer patients undergoing chemotherapy.
