input: The following are multiple choice questions (with answers) about medical knowledge.   **Question:** The concentration of a negative ion is 100 mMoUL extracellular and 10 mMo1/1 intracellular. What will be the Nernst potential for this ion?   (A) --10 mV   (B) +10 mV   (C) --61 mV   (D) +61 mV
