A medicine resident on her nephrology rotation notices that she has received more alerts of high serum potassium levels on her patients through the hospital's electronic medical record despite her census not having changed. On inspection of the laboratory result reports, critical alert markers were seen for potassium values greater than 5.5 mEq/L 3 days ago, whereas the same alerts have been seen for values > 5.0 mEq/L since yesterday. One of her patient's nurses asks if the patient should get an electrocardiogram. How has the potassium value reporting been affected?
