The patient has a history of substance abuse and was found down in his apartment lying on his right arm. He was last seen 24 hours earlier by his mother who lives in the same building. He is disoriented and unable to answer any questions. His vitals are HR 48, T 97.6, RR 18, BP 10075. You decide to obtain an EKG as shown in Figure 1. Which of the following is most likely the cause of this patients EKG results?? A: Hypocalcemia, B: Hypercalcemia, C: Hyperkalemia, D: Hypokalemia, E: Hypomagnesemia,  <response>: This is a clinical case scenario involving a 45-year-old male with a history of substance abuse who is found unresponsive and disoriented. He has bradycardia and a prolonged QT interval on EKG. The key findings here are the bradycardia, prolonged QT interval, and history of substance abuse. Bradycardia and prolonged QT can be caused by electrolyte abnormalities like hypokalemia, hypocalcemia, and hypomagnesemia. However, given his history of substance abuse, the most likely cause of his presentation is hyperkalemia from acute kidney injury or rhabdomyolysis. Hyperkalemia can lead to arrhythmias like bradycardia and prolong the QT interval. Hypokalemia would shorten the QT interval. The other electrolyte abnormalities are less likely in this scenario.C: Hyperkalemia
