COMPREHENSIVE QUESTIONS WITH CORRECT
ANSWERS
Of the following, which would not be indicative of ventricular fibrillation? -
correct-answer-Waves would be seen with every other complex
The following would be indicative of ventricular fibrillation:
No waves will be seen
The QRS will be more than 120ms
The rate will be 100-250
The patient will lose consciousness
If a premature ventricular contraction (PVC) comes from different foci, they are
referred to as which of the following? - correct-answer-Multifocal PVC's
If the PVC's come from different foci, they would be referred to as multifocal
PVC's.If the PVC's come from a common point or focus and appear the same
shape, they would be considered unifocal PVC's.

If they suspect the patient has premature ventricular contraction, which of the
following would the nurse look for on the ECG strip? - correct-answer-Irregular
rhythm and premature QRS complexes that are wide and uncommon
If they suspect the patient has premature ventricular contraction the nurse would
look for an irregular rhythm and premature QRS complexes that are wide and
uncommon on the ECG strip. This condition can also cause a loss of atrial kick and
reduce ventricular filling time causing a problem with cardiac output.
Which of the following would be considered the approximate O2 saturation of the
blood in the right atrium? - correct-answer-60-75%
The approximate O2 saturation of the blood in the right atrium would be 60-75%.
This is deoxygenated blood that returns to the heart from the body. It will have a
high concentration of C02.
Deoxygenated blood returns to the heart through the inferior and superior vena
cava and empties into which of the following? - correct-answer-Right atrium
Deoxygenated blood returns to the heart through the inferior and superior vena
cava and empties into the right atrium. From the right atrium, the blood goes
through the tricuspid valve into the right ventricle.

The stretching of muscle fibers in the ventricles is known as which of the
following? - correct-answer-Preload
Preload is the stretching of muscle fibers in the ventricles and is ascertained by
the pressure and amount of blood unexpended in the left ventricle at the end of
diastole. Afterload is the amount of pressure the left ventricle must push against
to pump blood into the circulation.
When the patient has no electrical activity in the heart and is unresponsive with
no cardiac output, the cardiac monitor would show which of the following? -
correct-answer-Asystole
When the patient has no electrical activity in the heart and is unresponsive with
no cardiac output, it is called asystole. This condition normally results from a
prolonged period of cardiac arrest where there was not effective resuscitation.
Patients with idioventricular rhythms require which of the following? - correct-
answer-Continuous ECG monitoring
Patients with idioventricular rhythms require continuous ECG monitoring and
constant assessment until their treatment restores hemodynamic stability. The
patient should be on bed rest with pacemaker equipment at the bedside with
atropine readily available.
