6. What is the mode of action of loop diuretics?

  • Inhibit Na+/K+/Cl- reabsorption, meaning a fewer number of electrolytes remain in the limb lumen and hence a lesser volume of water is present in the lumen too
  • Inhibit Na+/K+/Cl- reabsorption, meaning a greater number of electrolytes remain in the limb lumen and hence a greater volume of water is present in the lumen
  • Inhibit Na+/K+/Cl- reabsorption, meaning a fewer number of electrolytes remain in the limb lumen and hence a greater volume of water is present in the lumen too
  • Inhibit Na+/K+/Cl- reabsorption, meaning a greater number of electrolytes remain in the limb lumen and hence a lesser volume of water is present in the lumen

7. Loop diuretics are commonly used in treating which of the following conditions?

  • Peripheral oedema, pulmonary oedema and congestive heart failure
  • Pulmonary oedema, hypertension and hypokalaemia
  • Peripheral oedema, angina pectoris and stroke
  • Pulmonary oedema, hypertension and diabetes

8. Symptomatic diuretic-induced gout can be treated by which of the following?

  • Mannitol
  • Allopurinol
  • Bumetanide
  • Calcitriol

9. Hyperuricaemia is a recognised adverse effect of thiazide diuretics. Why?

  • Thiazides promot excess uric acid reabsorption
  • Thiazides prevent uric acid reabsorption
  • Secretion of thiazides competes with uric acid secretion
  • Thiazides blow up uric acid

10. Broadly speaking, how do thiazide diuretics act?

  • Actively promote Na+/Cl- excretion
  • Actively promote Na+/Cl- reuptake
  • Inhibit Na+/Cl- reuptake
  • Inhibit Na+/Cl- excretion

11. Where do thiazide diuretics have their main action?

  • Loop of Henle
  • Distal convoluted tubule
  • Glomerulus
  • Proximal convoluted tubule

12. What is the mode of action of loop diuretics?

  • Inhibit Na+/K+/Cl- reabsorption, meaning a greater number of electrolytes remain in the limb lumen and hence a greater volume of water is present in the lumen
  • Inhibit Na+/K+/Cl- reabsorption, meaning a greater number of electrolytes remain in the limb lumen and hence a lesser volume of water is present in the lumen
  • Inhibit Na+/K+/Cl- reabsorption, meaning a fewer number of electrolytes remain in the limb lumen and hence a greater volume of water is present in the lumen too
  • Inhibit Na+/K+/Cl- reabsorption, meaning a fewer number of electrolytes remain in the limb lumen and hence a lesser volume of water is present in the lumen too

13. True or false: Spirinolactone's efficacy is enhanced in hyperaldosteronism?

  • Chostochondritis
  • Hypercalcaemia
  • Polycystic Kidney Disease

15. True or false: thiazide diuretics increase Na+, Cl- & H2O excretion?

  • True
  • False

16. Hyperuricaemia is a recognised adverse effect of thiazide diuretics. Why?

  • Thiazides promot excess uric acid reabsorption
  • Secretion of thiazides competes with uric acid secretion
  • Thiazides blow up uric acid
  • Thiazides prevent uric acid reabsorption

17. Where do carbonic anhydrase inhibitors act?

  • Proximal Convoluted Tubule
  • Distal Convoluted Tubule

18. Symptomatic diuretic-induced gout can be treated by which of the following?

  • Allopurinol
  • Bumetanide
  • Mannitol
  • Calcitriol

19. Which of the following are examples of side effects of loop diuretics?

  • Cushing's disease, polymyalgia rheumatica and rheumatoid arthritis
  • Pneumonia, tuberculosis and lung cancer
  • Osteoporosis, hypokalaemia and deafness
  • Hypertension, oedema and diabetes

20. True or false: Spirinolactone's efficacy is enhanced in hyperaldosteronism?

  • True
  • False
