Pathophysiology 6501 Walden University Question with
Answers Rewarded Highest score.
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.

would reveal which of the following?:
Answer: XXY

Answer: Reduced protein synthesis
11. What principle should the nurse remember when trying to distinguish aging
