Questions on Hypermagnesemia
A 78-year-old man is brought to the emergency department with a 3-day history of fever and abdominal pain. Examination and urinalysis findings are consistent with pyelonephritis, causing sepsis and acute renal failure on a background of pre-existing chronic kidney disease (CKD). His temperature is 38.7°C (101.6°F), pulse is 110 beats/min, respirations are 22/min, and blood pressure is 98/65mmHg. A systems examination reveals a loss of deep tendon reflexes and ECG shows prolonged atrioventricular conduction. On further questioning, the patient also reveals that he has been feeling generally weak and nauseous, and has had two episodes of vomiting today. His past medical history is significant for CKD with an eGFR of 24 mL/min, and GERD for which he has recently been taking antacids. Considering the history and examination findings, which of the following electrolyte abnormalities is most likely to have caused this patient's presentation?
