Detailed explanation-1: -Potassium (K+) is the major intracellular cation, with 98% of the total pool being located in the cells at a concentration of 140-150 mmol/l, and only 2% in the extracellular fluid, where it ranges between 3.5 and 5 mmol/l.

Detailed explanation-2: -Hyperkalemia can be the result of intracellular to extracellular shift in the presence of acidosis, beta-blocker use, cellular breakdown, decreased excretion in renal failure, hypoaldosteronism or pseudohypoaldosteronism, and less commonly, increased potassium intake.

Detailed explanation-3: -comparison with extracellular fluid It differs from intracellular fluid (fluid within the cells) in that it generally has a high concentration of sodium and low concentration of potassium, while intracellular fluid is high in potassium and low in sodium.
