Advanced Patho NURS 5315 exam 1| Questions With Verified Answers 2024 Action potential Correct Answer: The process by which excitable cells transmit information from one to another. How is the action potential altered by a potassium imbalance? (Hyperkalemia) Correct Answer: The ECF has more K+ ions. The membrane potential becomes more positive (hypopolarized). Cells become MORE excitable. T waves peak. QRS complexes widen. Causes dysrhythmias, weakness, paresthesia. {If membrane p...
