Answer to Question 1

ANS: A
Intravascular and interstitial fluids have similar electrolyte compositions. However, plasma con-tains substantially more protein than interstitial fluid. Proteins, chiefly albumin, account for the high osmotic pressure of plasma. Osmotic pressure is an important determinant of fluid distribu-tion between vascular and interstitial compartments.

Answer to Question 2

ANS: A
Potassium (K+), magnesium (Mg2+), phosphate (PO43), sulfate (SO42), and protein constitute the main intracellular electrolytes.
