A healthy individual, weighing 60 kg, is infused with 1 L of isotonic saline to which 20 mEq of K+ has been added. Following the infusion, the plasma [K+] of this individual has increased from 3.5 mEq/L to 7.8 mEq/L
What is the most likely explanation for the development of hyperkalemia in this individual? A. shift of K+ from the ICF into the ECF B. impaired renal excretion of K+ C. the increase in plasma [K+] of 4.3 mEq/L is what is expected from the addition of 20 mEq/L of K+ to the ECF D. contraction of the ECF volume E. development of hyperosmolality
