Answer to Question 1

Correct Answer: 1
Rationale 1: Loop diuretics inhibit sodium in the loop of Henle and increase urine output.
Rationale 2: Thiazide diuretics block sodium in the distal tubule and nephron.
Rationale 3: Potassium-sparing diuretics block aldosterone.
Rationale 4: Some miscellaneous diuretics have this mechanism.

Answer to Question 2

Correct Answer: 2
Rationale 1: The medication does not need to be given with food.
Rationale 2: It is best to take loop diuretics in the morning, since they increase urine flow, which could lead to injury.
Rationale 3: Taking a loop diuretic at bedtime will cause nighttime urination and interfere with sleep.
Rationale 4: Late afternoon is too late, since the drug will increase urine flow.
