2. Potassium-sparing diuretics and NSAIDs may interfere with potassium excretion.1 pointTrueFalseMaybe

As hyperkalaemia can be lethal, ingestion of K+ results in its rapid excretion in the urine.1 ptsTrueFalse

K+ excretion is markedly influenced by :a) aldosteroneb) amount of Na+ delivered to tubulesc) rate of tubular secretion of H+d) all of the above .

An increase in the concentration of plasma potassium causes increase in:a) release of reninb) secretion of aldosteronec) secretion of ADHd) release of natriuretic hormonee) production of angiotensin II

The effect of renin-angiotensin-aldosterone mechanism include:Group of answer choicesDecrease blood pressureIncrease reabsorption of potassiumIncrease reabsorption of sodium and waterIncrease urine volume

) The amount of potassium excreted by the kidney will decreases if :a)distal tubular flow increasesb)circulating aldosterone level increasec) dietary intake of potassium increased)Na+ reabsorption by the distal nephron decreasese) the excretion of organic ions increase
