Potassium Shifts Flashcards
1
Q
Digitalis
A
Shifts K out of cell (HYPERkalemia)
Blocks Na/K ATPase
2
Q
Hyperosmolarity
A
Shifts K out of cell (HYPERkalemia)
Water flows out of cells to decrease plasma osmolarity, K goes with it. Increases K out in the plasma
3
Q
Hypo-osmolarity
A
Shifts K into cell (HYPOkalemia)
4
Q
Lysis of cells
Crush injury, rhabdomyolysis, cancer
A
Shifts K out of cell (HYPERkalemia)
5
Q
Acidosis
A
Shifts K out of cell (HYPERkalemia)
6
Q
Alkalosis
A
Shifts K into the cell (HYPOkalemia)
7
Q
B-blocker
A
Shifts K out of cell (HYPERkalemia)
8
Q
B-adrenergic agonist
A
Shifts K into the cell (HYPOkalemia)
Increases Na/K ATPase
9
Q
High blood sugar
insulin deficiency
A
Shifts K out of cell (HYPERkalemia)
10
Q
Insulin
A
Shifts K into the cell (HYPOkalemia)
Increases NA/K ATPase
