a) Potassium decrease by 0.3meq/l
b) K+ increase by 0.3 meq/l
c) Potassium decrease by 1.5 meq/l
d) K+increase by 1.5 meq/l
Free answer
a
Acid-base disturbances cause potassium to shift into and out of cells. This is called internal potassium balance and was discovered in 1956. In alkalosis (increase in ph,) K+ falls and in Acidosis potassium concentration will increase. For every 0.1 fall in ph, K+ increases by 0.3-0.6 meql/l
Metabolic acidosis- in a plasma potassium concentration that is elevated in relation to total body stores.
