Heexhibits postural hypotension and skeletal muscle weakness
Question:
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). 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
