Question 2
The nurse is reviewing normal cardiac conduction with a new graduate nurse. What should the nurse explain when the impulse reaches the bundle of His? Select all that apply.
Note: Credit will be given only if all correct choices and no incorrect choices are selected.◦ Conduction of the impulse bifurcates into the right and left bundle branches.
◦ Conduction of the impulse penetrates the atrioventricular valves.
◦ Conduction creates a flat line after the P wave on the ECG rhythm.
◦ Conduction of the impulse continues to the Purkinje fibers.
◦ Conduction of the impulse is slowed because of calcium ions.
