Ca2+/K+/Na+ Flashcards
(4 cards)
How does aldosterone affect potassium?
It increases potassium secretion into the urine. So hypoaldosteronism can be associated with hyperkalaemia and mild metabolic acidosis.
anti-hypertensive drugs?
Which medications can cause hyperkalaemia?
-Aldosterone antagonists (like spironolactone and eplerenone)
-ACE inhibitors (e.g. ramipril)
-Angiotensin 2 receptor blockers (e.g. candesartan)
-NSAIDs (like naproxen and ibuprofen)
What are the mainstay treatments for hyperkalaemia?
Insulin and dextrose with IV calcium gluconate
What are the ECG changes seen in a hyperkalaemic patient?
Tall peaked T waves
Absent/flattened P waves
Prolonged PR intervals
Broad QRS complexes
Sinusoidal wave pattern
