Answer to Question 1

Correct Answer: 2

Rationale 1: Potassium citrate increases the rate of removal of lithium.
Rationale 2: There are many different medications that interact with lithium.
Rationale 3: Diuretics cause an increase in the excretion of sodium and increase the risk for toxicity.
Rationale 4: Sodium bicarbonate increases the rate of removal of lithium.

Global Rationale: Diuretics cause an increase in the excretion of sodium and increase the risk for toxicity. Potassium citrate increases the rate of removal of lithium. Diuretics cause an increase in the excretion of sodium and increase the risk for toxicity. Sodium bicarbonate increases the rate of removal of lithium.
