Question

2. Hypokalemia of the interstitial fluid and plasma has which of the following effects on an excitable cell such as muscle or nerve (Circle one answer from each grouping on three choices) (10 Points) A. The cell is more likely to Depolarize B. The cell is more likely to Hyperpolarize C. The cell is no more likely either to Depolarize or Hyperpolarize D. The cell's resting membrane potential is less negative E. The cell's resting membrane potential is more negative F. The cell's resting membrane potential is not affected G. The Nernst Potential for potassium is more positive than that seen in normokalemia H. The Nernst Potential for potassium is more negative than that seen in normokalemia 1. The Nernst Potential for potassium will remain unchanged from that seen in normokalemia J. The Nernst Potential for sodium is more positive than seen in normokalemia K. The Nernst Potential for sodium is more negative than that seen in normokalemia L. The Nernst Potential for sodium will remain unchanged from that seen in normokalemia

Answer 1

In Namokalemia the Neenst Potential is - – 90 mv. In Hypokalemia the Neinst potential is = – 96 mv. so The Nernst Potential for potassuum is more negative than that seen in naimokalene - H The Neinst potential for Nat = +55mv. so the Neinst potential for sodmens will remain enchanged from that seen in namokalemia - ①
