WGU D236 pathophysiology: Objective Assessment Questions and Verified Answers | Latest 2023/2024 GRADED A+. A major function of potassium is to conduct nerve impulses in muscles. Too low and muscle weakness occurs and too much can cause muscle spasms. This is especially dangerous in the heart muscle and an irregular heartbeat can cause a heart attack The body uses the Protein Buffering System, Phosphate Buffering System, and Carbonic AcidBicarbonate System to regulate and maintain homeostatic...

NSG 5003 WEEK 1 QUIZ / NSG5003 WEEK 1 QUIZ: ADVANCED PATHOPHYSIOLOGY (LATEST 2022/2023):SOUTH UNIVERSITY -Why is it possible for potassium to diffuse easily into and out of cells? Potassium has a greater concentration in the ICF. Sodium has a greater concentration in the ECF. The resting plasma membrane is more permeable topotassium. An excess of anions is inside the cell. Instructor Explanation: Because the resting plasma membrane is more permeable to K+ than to Na+, K+ can easily diffuse ...
