When calculating the membrane potential for a potassium channel, is Na+ included?

For example (a or b):

a. V= (RT/F)*ln ((Pk[K]out + PNa[Na]out)/(Pk[K]in + PNa[Na]in))

b. V= (RT/F)*ln ((Pk[K]out )/(Pk[K]in))
       = (RT/F)*ln (([K]out )/([K]in))

Each ion has its own Equilibrium Potential, the steady electrical potential that would be produced if the membrane were permeable to only that ion.



So do it per ion, don't mix
