Question
A 25-year-old male was pulled comatose from the bottom of a private swimming pool. Immersion time was unknown. His pupils were dilated, and his breathing was agonal. CPR was initiated at the scene, and the paramedics intubated him at once. Which of the following electrolyte disorder is most likely to be the cause of the cardiac arrest?Question 96Answera.Hypokalemia.b.Hypomagnesemiac.Hypocalcemiad.Hyponatremia.
Solution
Based on the given scenario, a 25-year-old male was found comatose at the bottom of a private swimming pool. It is mentioned that his pupils were dilated and his breathing was agonal. CPR was initiated at the scene and the paramedics intubated him immediately. The question asks which electrolyte disorder is most likely to be the cause of the cardiac arrest.
To determine the likely electrolyte disorder, we need to consider the symptoms presented. Dilated pupils and agonal breathing are indicative of severe brain injury or hypoxic-ischemic encephalopathy, which can occur due to lack of oxygen to the brain. In this case, the lack of oxygen could be a result of drowning.
Among the given options, the electrolyte disorder that is most likely to cause cardiac arrest in this scenario is hypokalemia, which refers to low levels of potassium in the blood. Hypokalemia can lead to cardiac arrhythmias and, in severe cases, cardiac arrest.
Therefore, the answer to the question is a. Hypokalemia.
