Does an increase or decrease in potassium extracellular ions hyperpolarize a cell?

An extracellular increase of potassium (increase of intracellular Sodium) causes depolarization. The opposite, I presume, meaning high intracellular potassium (inside cell) and high extracellular sodium (outside cell) would be hyperpolarization

Increase
Does an increase in ECF K plus level increase heart rate?
Potassium levels DECREASE heart rate, and maybe lead to severe cardiac arrest.and for sure, this is a mechanism of how potassium level in ECF can decrease heart rate:first, the potassium level increase in ECF making its efflux increase, due to activation of potassium channels in pacemaker cells, then the slope of pacemaker action potential will decrease, which means that the duration of one beat is prolonged, and this lead to decrease the numbers of beats in one minute, which by turn means that the heart rate is decreased.
Does the pH of the solution increase decrease or stay the same when you add solid potassium chloride to dilute solution of potassium hydroxide?
The pH remain constant.
An explosion casualty suffering from crush injuries of the lower extremities has been admitted to your hospital with severe hyperkalemia What emergency treatment is recommended?
Limit mannitol, administer glucose-insulin drip, calcium chloride and/or sodium bicarbonateDO NOT LIMIT LIQUIDS!Treatment of hyperkalemia may include any of the following measures, either singly or in combination:A diet low in potassium (for mild cases).Discontinue medications that increase blood potassium levels.Intravenous administration of glucose and insulin, which promotes movement of potassium from the extracellular space back into the cells.Intravenous calcium to temporarily protect the heart and muscles from the effects of hyperkalemia.Sodium bicarbonate administration to counteract acidosis and to promote movement of potassium from the extracellular space back into the cells.Diuretic administration to decrease the total potassium stores through increasing potassium excretion in the urine. It is important to note that most diuretics increase kidney excretion of potassium. Only the potassium-sparing diuretics mentioned above decrease kidney excretion of potassium.Medications that stimulate beta-2 adrenergic receptors, such as albuterol and epinephrine, have also been used to drive potassium back into cells.Medications known as cation-exchange resins, which bind potassium and lead to its excretion via the gastrointestinal tract.Dialysis, particularly if other measures have failed or if renal failure is present.
How does hypoglycemia lead to hyponatremia?
when you have high levels of glucose in the blood (hyperglycaemia) this will draw water out of cells due to the increase in osmolarity. With increased water in to the extracellular fluid it will decrease the concentration of sodium (hyponatraemia)
