TEST 2026 QUESTIONS WITH
CORRECT ANSWERS GRADED A+
◍ Junctional Rhythm.
Answer: Interpretation
◍ Electrocardiogram.
Answer: A tracing or graphic representation of the heart`s electrical activity
used to identify irregularities in heart rhythm and physical changes in the
heart muscle.
◍ Stroke Volume.
Answer: Amount of blood ejected from the ventricles per beat, dependent on
preload and afterload.
◍ Cardiac Output.
Answer: Amount of blood pumped from the heart in one minute, calculated
as Heart Rate (HR) X Stroke Volume (SV).
◍ SA Node.
Answer: Located on the posterior wall of the right atrium, initiates the
heartbeat and serves as the heart's primary pacemaker.Rate 60-100 bpm
◍ AV Node.
Answer: Located on the floor of the right atrium, has pacemaker cells that
initiate the heartbeat at a slower rate than the SA node"Secondary
pacemaker"Rate 40-60 bpm
