A 44-year-old man is recovering from third degree burns over 50% of his body surface area.
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). He exhibits 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?
