Im not very good with this, but
Average speed
Speed = distance over time
Take the distance and divide it by the time i got
60.8695652174
But not sure i did it correctly. Worth a shot.
Intracellular Potassium Shifts and Impaired Potassium Excretion leads to elevated plasma K levels.
What is Hyperkalemia?
- Hyperkalemia, a potentially lethal condition, develops when serum potassium levels rise above 5.5 mmol/l.
- Potassium is the most common intracellular cation and is crucial for many physiological functions, at a concentration of 100-150 mmol/l. The digestive system quickly and usually fully absorbs potassium.
Causes:
- Increased Potassium intake: In adult patients with normal renal function, increased dietary potassium intake is a very rare cause of hyperkalemia, but it can be a significant factor in people with kidney disease.
- Intracellular Potassium Shifts: Large amounts of intracellular potassium can be released into the extracellular area as a result of cellular damage. Excessive activity, rhabdomyolysis after a crush injury, or other hemolytic processes can all be to responsible for this.
- Impaired Potassium Excretion: The most frequent cause of hyperkalemia is acute or chronic renal disease. Hyperkalemia may also result from tubular dysfunction brought on by aldosterone insufficiency or insensitivity.
