Total body sodium content determines extracellular fluid volume, and is regulated by the balance between sodium intake and sodium loss. Oubain is a poison that causes blockage of the Na+/K+ ATPase. Which of the following would occur after administration of oubain? Explain why?
a) Increased extracellular sodium concentartion
b) Increased intracellular potassium concentration
c) Increased cellular water concentration
d) increased intracellular chloride concentration
this question is confusing me. if the poison blocks the pump then basically na+ and k+ cannot move into and out of the cell. can any one explain it to me how would it increase any thing??
