Answer to Question 1

ANS: A
Serum K+ concentration is determined primarily by the pH of extracellular fluid and the size of the intracellular K+ pool. In extracellular acidosis, excess H+ ions are exchanged for intracellular K+. Movement of K+ from intracellular to extracellular spaces may produce dangerous levels of hyperkalemia.

Answer to Question 2

ANS: C
Hypokalemia (reduced serum potassium) disturbs cellular function in a number of organ systems. These include the gastrointestinal, neuromuscular, renal, and cardiovascular systems.
