Role of the Kidney in Potassium Excretion
N.A. is brought to the ED for management of intentional drug overdose. He ingested 56 tables of Amoxicillin (prescribed 875 mg po BID for 28 days for a sinus infection) and 30 tablets of Seconal (prescribed 100 mg capsules po QHS prn for sleep). His respirations are slow and shallow, and he is non-responsive. He is admitted to the critical care unit to be closely monitored for the development of ventilatory failure and renal failure, which often accompany drug overdose of Amoxicillin (renal failure) and secondary (ventilatory failure). His urine output is decreased at about 20 mL/hr.Role of the Kidney in Potassium Excretion

His laboratory values and serum K+ = 6.7 mEq/L; arterial blood gas: pH = 7.13, PaCO2 = 65 mm Hg; PaO2 = 88 mm Hg, and HCO3- = 16 mEq/L. Answer each question completely, and focus on pathophysiology. Remember to reference your answers properly. 1. What is the most likely cause of N.A.’s potassium imbalance? Explain the role of the kidney in potassium excretion. (2 points) 2. What is the relationship between acid-base balance and serum potassium level? (2 points) 3. What is the reason for N.A.’s low urine output? How should his fluids be managed? (2 points) 4. Categorize and explain the probable cause of N.A.’s acid-base disorder. (2 points) 5. Can N.A. compensate for his acid-base disorder? Why or why not? (2 points) 6.
