p. 195; rate of change in electrolyte disturbances often more important than absolute values.
Nernst equation is a bit easier to manage if you use the version
Em = -61 log [K]in/[K]out since K is always higher inside than outside, the math is a bit easier. answer is the same. -61 = RT/ZF. the reason hypothermia doesn't really change resting membrane potential is that T is absolute temperature (not Farenheit or centigrade) so it doesn't change much with hypothermia.
p. 195 & 196 intracellular shifts of potassium important in acidosis, beta blockers, glucose levels.
see Costanzo, p. 277, showing this figure:
