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...

An aide asks the nurse why people who have neurofibromatosis will show varying degrees of the disease. Which genetic principle should the nurse explain to the aide? Selected Answer: b. Expressivity Correct Answer: b. Expressivity Question 2 1 out of 1 point s Why is potassium able to diffuse easily in and out of cells? Selected Answer: c. Because the resting plasma membrane is more permeable to potassium Correct Answer: c. Because the resting plasma membrane is more permeab...

Resting membrane potential is created by differences between the inside and outside of the cell in ion concentrations of 1. K+ 2. K+ and Ca++ 3. K+, Na+ and Cl- 4. Na+, Ca++ and Cl- - Answer- K+, Na+, and Cl- Excitation of the postsynaptic neuron is caused by the neurotransmitter 1. gamma amino butyric acid 2. glycine 3. para amino butyric acid 4. glutamate - Answer- Glutamate Wave III of the BAER is generated by the 1. superior olivary complex 2. inferior colliculus 3. la...

Advanced Med-Surg Principles Jersey College Final Exam Questions With Solutions Ch 13: What are exchanged for potassium ions during alkalosis or acidosis? - hydrogen ions (ie: metabolic acidosis results in hyperkalemia as H ions are shifted into the ell to raise the pH and potassium leaves the cell and enters the bloodstream) Ch 13: What is necessary for neuromuscular and cardiovascular function? - potassium Ch 13: What helps to regulate muscle contraction and relaxation? - ca...

1. A runner has depleted all the oxygen available for muscle energy. Which of the following will facilitate his continued muscle performance? : Answer: Anaerobic glycolysis 2. What causes the rapid change in the resting membrane potential that initi- ates an action potential? : Answer: Sodium gates open, and sodium rushes into the cell, changing the membrane potential from negative to positive. 3. A 12-year-old male is diagnosed with Klinefelter syndrome. His karyotype would reveal which of ...

NSG 531 Rush Advanced Pharmacology: Exam 3 Questions With Correct Answers Latest Updated 2024/2025 / Graded A+. what is the difference between cardiac myocyte action potential and that of the CNS or ANS? - ANSWER nerve cell action potential is very short cardiac action potential is much longer they are longer to have adequate filling time in order to get a good contraction for a reasonable bolus of blood the only way this can happen is if the action potential is longer this will also mean ...

NSG 5003 WEEK 1 QUIZ / NSG5003 WEEK 1 QUIZ: ADVANCED PATHOPHYSIOLOGY (LATEST 2024/2025):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 ...
