D) Routine monitoring of electrolytes, renal function, glucose, pulse oximetry and blood gases may be helpful in patients with severe toxicity.
E) A methemoglobin concentration should be obtained, if clinically indicated (patient is cyanotic, short of breath, or has mental status changes). Pulse oximetry may be inaccurate and calculated oxygen saturation will be normal in presence of methemoglobinemia.
