What is the relationship between acid-base balance and serum potassium level? What is the reason for LSs low urine output? How should her fluids be managed?

LS is brought to the emergency department for management of acute mushroom poisoning. Her respirations are slow and shallow and she is nonresponsive. She is admitted to the critical care unit to be closely monitored for the development of respiratory failure and renal failure which often accompany mushroom poisoning. Her urine output is decreased to about 20 ml/hr. Her laboratory values are serum K+ = 5.7 mEq/L; arterial blood gases (ABGs): pH = 7.13 PaCO2 = 56 mm Hg PaO2 = 89 mm Hg HCO3- = 18 mEq/L.
What is the most likely cause of LSs potassium imbalance? Explain the role of the kidney in potassium excretion.
