Briefly Describe about the hypokalemia?
Hyperkalemia occurs when serum K levels are greater than 5 1n ML. High plasma K results in cardiac arrhythmias. A K level of 8.0 m MIL can cause cardiac arrest and death. Hyperkalemia can occur in severe acidosis when the activity of Na+/ K+- ATPase is inhibited resulting in redistribution of K. It can also occur in severe kidney diseases where ability to excrete K is impaired especially if K consumption is not restricted and patient is experiencing tissue or RBC breakdown.
