Dysrythmias EXAM 2025-2026. QUESTIONS WITH CORRCET AND DETAILED ANSWERS. A+ GRADED., Exams of Nursing

Dysrythmias EXAM 2025-2026. QUESTIONS WITH CORRCET AND DETAILED ANSWERS. A+ GRADED. In analyzing a patient's electrocardiographic (ECG) rhythm strip, the nurse uses the knowledge that the time of the conduction of an impulse through the Purkinje fibers is represented by the PR interval. Rationale: The PR interval represents depolarization of the atria, AV node, bundle of His, bundle branches, and the Purkinje fibers, up to the point of depolarization of the ventricular cells. When needing to estimate the ventricular rate quickly for a patient with a regular heart rhythm using an ECG strip, the nurse will use the 3-second markers to count the number of QRS complexes in 6 seconds and multiply by 10.
