Question: A 44 year old man is recovering from third degree burns over 50% of his body surface area.

His serum potassium level is low (2.9 mEq/L). Heexhibits postural hypotension and skeletal muscle weakness. If the equilibrium potential for K+ in a neuron is 105 mV and the equilibrium potential for Na + is +55 mV, what would be an approximate value for the resting membrane potential for a neuron in this man?

A.+20 mV

B.+48 mV

C.+80 mV

D.?25 mV

E.?48 mV

F.?96 mV
