Which symptom would be a concern when monitoring a patient on corticosteroids?

Monitoring a patient on corticosteroids requires careful attention to various potential side effects, particularly those related to weight changes. Weight gain is a significant concern because corticosteroids can cause an increase in appetite and alter metabolism, leading to significant fluid retention and fat redistribution. This is particularly important in patients who may already be at risk for obesity or related metabolic conditions.

Corticosteroids also have the potential to influence the body's regulation of electrolytes and fluids, which can further exacerbate weight gain and result in additional health complications, such as hypertension and increased risk of cardiovascular issues. Being aware of these changes allows for timely interventions, including lifestyle modifications and possible adjustments in medication dosing.

Joint pain, nausea, and dry skin can occur in patients for various reasons but are typically not as directly associated with the adverse effects of corticosteroids as weight gain is. While these symptoms should still be monitored and managed if they arise, weight gain carries a more immediate concern due to its potential health impact and association with long-term use of corticosteroids.
