TOPIC 1: DIURETICS
12 Questions • 8.8% of Exam • Focuses on various diuretic classes and their uses in treating conditions like hypertension and heart
failure.
QUESTION 1
Thiazide diuretic
Correct Answer: Hydrochlorothiazide.
Rationale: "Hydrochlorothiazide" is a correct answer because it is a medication that specifically belongs to the thiazide
diuretic class, a group of diuretics that work by inhibiting the sodium-chloride transporter in the kidneys. This classification is
due to its chemical structure, mechanism of action, and therapeutic use, all of which align with the characteristics of thiazide
diuretics.
QUESTION 2
Loop diuretic
Correct Answer: Furosemide.
Rationale: Furosemide is a loop diuretic because it acts on the Loop of Henle in the kidneys, a specific region where water
and electrolyte reabsorption primarily occurs, to inhibit sodium and chloride reabsorption, leading to increased urine
production. This mechanism of action is unique to loop diuretics, distinguishing them from other types of diuretics that act on
different regions of the nephron.
QUESTION 3
Potassium sparing diuretic
Correct Answer: Spironolactone.
Rationale: Spironolactone works by blocking the action of aldosterone, a hormone that promotes sodium retention and
potassium excretion, thereby allowing potassium levels to be preserved and not excreted, which is a key characteristic of
potassium-sparing diuretics. This mechanism of action helps to counteract the effects of aldosterone, resulting in the
retention of potassium and water in the body.

QUESTION 4
Hydrochlorthiazide (Thiazide diuretics) Uses
Correct Answer: Treat hypertension
-edema from heart failure
-hepatic cirrhosis.
Rationale: Hydrochlorothiazide, a thiazide diuretic, is used to treat hypertension as it helps reduce blood volume and lowers
blood pressure. The other options, edema from heart failure and hepatic cirrhosis, are conditions where thiazide diuretics
can alleviate symptoms such as fluid retention and swelling, making them secondary uses of the medication.
QUESTION 5
Furosemide (loop diuretics) uses
Correct Answer: Treat fluid retention caused by heart failure
-renal dysfunction
-cirrhosis
-hypertension
-pulmonary edema.
Rationale: Furosemide, as a loop diuretic, works by inhibiting the sodium-potassium-chloride cotransporter in the distal
convoluted tubule of the kidneys, leading to increased urine production and decreased fluid retention in conditions such as
heart failure, renal dysfunction, cirrhosis, hypertension, and pulmonary edema, which are characterized by excessive fluid
accumulation. This mechanism of action makes furosemide an effective treatment for these conditions, resulting in its
specific use in managing fluid retention caused by these conditions.
QUESTION 6
Spironolactone (potassium-sparing diuretics) action
Correct Answer: Promote sodium and water excretion and potassium retention.
Rationale: Spironolactone acts as a potassium-sparing diuretic by inhibiting the action of aldosterone, a hormone that
promotes sodium and water reabsorption and potassium excretion in the kidneys. By blocking aldosterone, spironolactone
ultimately leads to increased excretion of sodium and water, while allowing potassium to be retained in the body.
