A 62-year-old woman who was discharged from the hospital several hours ago following
evaluation of optic neuritis now has swelling of her ankles. Prior to admission, the patient
had a 3-day history of loss of vision and poor color perception in her right eye. Visual acuity
on admission was less than 20/200 in her right eye and was 20/40 in her left eye. The
remainder of the physical examination was noncontributory. Blood pressure on admission
was 140/80 mm Hg. The patient had been otherwise healthy and had been taking no
medications. She has never worn corrective lenses. Family history is significant for thyroid
disorder. During her hospital stay, the patient received intravenous methylprednisolone
therapy for the past four days. Vital signs today are temperature 37.2°C (99.0°F), pulse
100/min, respirations 14/min, and blood pressure 150/95 mm Hg. Physical examination
shows ankle edema but is otherwise unchanged from physical examination done on
admission. Laboratory studies are obtained. Which of the following serum laboratory study
results is most likely in this patient?
A) Decreased magnesium concentration
B) Decreased sodium concentration
C) Increased calcium concentration
D) Increased glucose concentration
E) Increased potassium concentration
what the hell is this?
