CCI CRAT EXAM PRACTICE TEST 3
COMPLETE QUESTIONS AND CORRECT
ANSWERS |ALREADY GRADED A+
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? - ✔✔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? - ✔✔ANSWER✔✔-Continuous ECG monitoring
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?
- ✔✔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? - ✔✔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? -
✔✔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? - ✔✔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? - ✔✔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.
