Two patients presented to the Emergency Department. They were experiencing two different sets of signs and symptoms. The first patient, Patient A, is a very old woman who presented with cardiac issues. Her ECG (electrocardiogram) result was very abnormal. She was admitted to the ICU on the same day. She told the physician on duty that she had diarrhea for 1 and a half months. The admission laboratory work showed a potassium level of 1.1 mEq/L. The other patient, Patient B, is a 15-year-old female, of Chinese descent, who experiences dizziness, malaise, nausea, loss of appetite, chilly sensation, dyspnea, and projectile vomiting. Her laboratory results show a significant decrease/deficiency with the trace element selenium. A. What is a likely reason for Patient A's cardiac abnormalities? Explain why. B. Why was Patient A's potassium level so low? Discuss your answer. C. What is the most probable diagnosis for Patient B? D. What other diseases are associated with selenium defiency?
