A patient is diagnosed with a disorder affecting the P-Wave within the cardiac cycle/ The nurse should plan to care for which cardiac action?
|
|
atrial repolarization
|
|
|
ventricular repolarization
|
|
|
atrial depolarization
|
|
|
ventricular depolarization
|
Explanation:
Detailed explanation-1: -The P wave represents the electrical depolarization of the atria. In a healthy person, this originates at the sinoatrial node (SA node) and disperses into both left and right atria.
Detailed explanation-2: -The P wave indicates atrial depolarization. The P wave occurs when the sinus node, also known as the sinoatrial node, creates an action potential that depolarizes the atria.
Detailed explanation-3: -The most important intervention for a patient with pulseless VT or VF is rapid defibrillation (electrical countershock).
Detailed explanation-4: -The P wave results from atrial depolarization. The QRS complex is a result of ventricular depolarization and indicates the start of ventricular contraction.
