Answer 1

True. Those patients having any adverse reaction with sulfa drugs cannot safely receive other loop diuretics such as lasix, torsemide etc.the patient who is allergic to sulfa drug can remain allergic to lasix and other loop diuretics. But they can receive potassium sparing diuretics like spiranolactone.

True.Aldosterone acts on the kidney to retain sodium and water and excrete potassium in the urine. When the BP falls,the adrenal glands are stimulated and aldosterone is produced.Aldosterone helps in sodium reabsorption from urine, sweat and other body fluids. Thus its helps to maintain saodium and water retention in the body.

False. Loop diuretics are having a shorter duration of action.hence loop diuretic are administred twice daily. Where thiazide diuretics are having the duration of action upto 12 hours. hence a single dose is enough for a day.Their effectiveness usually begins within 2 hours of consumption.

Yes. Loop diuretics are the only class of diuretics that may cause ototoxicity.the common loop diuretic that cause ototoxicity id injection lasix.
