Nephrotic syndrome

7. A patient on digoxin develops hyperkalemia. Why is this concerning?

Increased digoxin toxicity risk

Decreased digoxin efficacy

Hypernatremia development

Hypercalcemia risk

8. A patient with a serum potassium of 3.2 mEq/L presents with muscle weakness and fatigue. Which condition is this patient experiencing?

Hyperkalemia

Hypokalemia

Submit

16. A patient with hypokalemia and hypomagnesemia requires correction of both. Why is magnesium important?

Potassium cannot be corrected without magnesium repletion

Magnesium increases potassium excretion

Magnesium is required for potassium cellular uptake

Magnesium prevents hyperkalemia
