Which of the following must be assessed regularly in patients on corticosteroid treatment?

In patients receiving corticosteroid treatment, regular assessment of electrolyte levels, particularly potassium, is essential. Corticosteroids can lead to electrolyte imbalances, including hypokalemia (low potassium levels), which can result in significant health issues such as muscle weakness, arrhythmias, and other cardiovascular complications. Monitoring helps ensure that any imbalances are addressed promptly, maintaining the patient’s overall health during corticosteroid therapy.

While eye exams for cataracts, liver function tests, and blood glucose levels are also important in the context of corticosteroid use—due to the potential side effects of long-term corticosteroid therapy—the focus on potassium reflects a critical aspect of managing electrolyte balance which can be immediately life-threatening if not properly monitored.
