Most common cause of hypokalemia
A. Upper G.I potassium loss
B. Lower G.I. potassium loss
C. Renal potassium loss
D. Post operative potassium loss
Most common cause of hypokalemia
A. Drugs
B. Endogenous hormone production
C. Intrinsic renal defects
D. Fistula
Cisplatin induce hypokalemia is predominantly from
A. Renal potassium wasting
B. Increase distal tubular delivery of a nonreabsorbable anion
C. Increases collecting duct potassium secretion
D. Magnesium depletion

| Increased Urinary Potassium Levels | Decreased Urinary Potassium Levels | |
| 1 | Diuretic therapy. | Amiloride |
| 2 | Cortisone therapy. | I/V glucose infusion. |
| 3 | Thiazides. | Dehydration |
| 4 | Chronic renal failure. | Malnutrition |
| 5 | Starvation. | Malabsorption |
| 6 | Hyperaldosteronism. | Addison disease |
| 7 | Excessive intake of licorice. | Vomiting |
| 8 | Renal tubular acidosis. | Acute renal failure where urinary K will be low but the patient will have hyperkalemia. |
| 9 | Cushing’s syndrome. | Diarrhea |
| 10 | Alkalosis. | |
| 11 | Drugs like penicillin and carbenicillin |
