EKG NHA MAIN EXAMINATION SET QUESTIONS AND
SOLUTIONS RATED A+
✔✔loss of capture (failure to depolarize) - ✔✔the pacing activity continues to occur
without evidence that the electrical activity has depolarized or captured the myocardium
✔✔bundle branch block (BBB) - ✔✔Occurs when the electrical impulse is blocked from
traveling down the bundle of His or bundle branches. Results in the ventricles beating at
a different rate than the atria. Also called a heart block.
✔✔sinus dysrhythmia - ✔✔variation in heart rate during breathing cycle
✔✔premature ventricular contraction (PVC) - ✔✔a ventricular contraction preceding the
normal impulse initiated by the SA node (pacemaker)
✔✔complete heart block - ✔✔results in the ventricles depolarizing independently from
the atria
✔✔Pacemaker Spike - ✔✔precedes each pacemaker-induced QRS complex-- narrow,
biphasic deflection.
✔✔Take a pulse of an infant - ✔✔use the brachial artery located on the inside of the
upper arm
✔✔Dextrocardia - ✔✔heart displaced to the right
✔✔For a patient who has dextrocardia... - ✔✔place lead 1 on the left sternal border, 4th
intercoastal border
✔✔Loose electrodes can result in: - ✔✔wandering baseline.
✔✔FIRST TO LAST documentation - ✔✔temperature, pulse, respirations, and blood
pressure
✔✔V9 Lead - ✔✔left paraspinous border
✔✔Crossed lead wires - ✔✔electrical interference
✔✔ventricular depolarization - ✔✔QRS complex
✔✔Which of the following is the maximum number of tracing that an EKG technician
can obtain on the same patient using a single set of disposable electrodes? - ✔✔2
✔✔New Born Respiratory Rate Range - ✔✔30-60 min
, ✔✔Elevated ST segment - ✔✔myocardial infarction
✔✔Accelerated Idioventricular Rhythm (AIVR) - ✔✔40-120
- occur in short burst, usually following MI
- mostly asx with no progression to vtach / vfib
✔✔AC interference - ✔✔uniform spikes on an EKG caused by electrical interference.
✔✔RL electrode placement - ✔✔right lower abdomen
✔✔Depressed ST segment - ✔✔myocardial ischemia
✔✔gestation - ✔✔growth process from conception to birth
✔✔atrial depolarization - ✔✔P wave
✔✔Sinus Arrhythmia - ✔✔A sinus rhythm in which the rate varies with respiration,
causing an irregular rhythm.
✔✔Libel - ✔✔written defamation
✔✔Slander - ✔✔spoken defamation
✔✔Purkinje fibers - ✔✔fibers in the ventricles that transmit impulses to the right and left
ventricles, causing them to contract
✔✔atrial fibrillation - ✔✔rapid, random, ineffective contractions of the atrium
✔✔What is the hearts primary pacemaker? - ✔✔SA node
✔✔ventricular tachycardia - ✔✔a very rapid heartbeat that begins within the ventricles
✔✔ventricular hypertrophy - ✔✔Increase in size of cardiac muscle in the heart's
ventricles. Left ventricular hypertrophy (LVH) may be a sign that the heart is working
harder to pump blood to the rest of the body.
✔✔apical pulse - ✔✔the pulse on the left side of the chest, just below the nipple
✔✔First degree AV block - ✔✔prolonged PR interval
✔✔second degree AV block mobitz type 2 - ✔✔-PR interval is constant
-atrial conduction to ventricle is intermittent
-disease below AV node in His bundle
