Question

A 30 year old man is diagnosed with metabolic acidosis at the emergency room due to severe diarrhea, the patient starts to have arrhythmia and the physician asks for serum K+ level. 
 Which is the most likely explanation of the patient’s arrhythmia?

Answer

the patient has hyperkalemia due to a decrease in activity of K+ channels at renal principal cells by the acidosis, also extra H+ ions enter cells in exchange for K+

Answer

the patient has hypokalemia due to an increase in activity of K+ channels at renal principal cells by the acidosis, also extra H+ ions enter cells in exchange for K+

Answer

the patient has normal serum K+ levels but high levels of H+ ions

Answer

the patient has hyperkalemia due to increased renal reabsorption of K+ at renal principal cell and increased reabsorption of H+ ions by the acidosis

Answer

the patient has hypokalemia due to the decreased renal reabsorption of K+ at renal principal cell, also reduced excretion of H+ ions by the acidosis
