EXAM 100 QUESTIONS AND CORRECT DETAILED
ANSWERS WITH RATIONALES (100% VERIFIED
ANSWERS) |AGRADE
Atrial tachycardia that occurs spontaneously and is self limiting is
called:
Paroxysmal atrial tachycardia (PAT)
What does the horizontal axis on the ECG paper represent?
Time
What does preparing the skin for electrode placement by applying a skin
prep solution do?
The skin prep solution increases the adherence of the electrode to the
skin.
The skin prep solution helps decrease moisture and friction so that the
electrodes can stick while preventing the adhesive from pulling off the
skin with removal.
You are caring for Mr. Adam, a 19 year old male admitted after he
tripped and experienced a 30 foot fall while out hiking. He has broken
ribs, a fractured femur, and collarbone. You identify his cardiac rhythm
on the monitor as sinus rhythm with premature atrial contractions
(PAC). You go in to evaluate him. He is sitting in bed watching
television. You ask him how he is feeling. What is his most likely
response?
What? I didn’t feel anything. What’s going on?
Temporary transcutaneous pacing is accomplished by:<\/p>\n\n\n\n
Placement of two large pacing patches onto the chest wall to deliver the
electrical stimulus.
The three periods of the refractory phase of the cardiac cycle are:
Absolute, Relative, and Vulnerable
Sinus arrest may be life threatening if atrial activity is not restarted.
True
Which of the following best describes premature ventricular contractions
(PVCs)?
PVCs can be harmful if they fall on the T-wave during the relative
refractory period.
The ECG strip with a single pause will have little effect on the patient’s
blood pressure.
True
Which of the following is the rate for a junctional escape rhythm?
40-60 beats per minute
The main difference between MCL1 and V1 is that:
V1 is a unipolar lead and MC1 is a bipolar lead.
Blood flows through the right atrium, tricuspid valve, and right ventricle
under high pressure.
False
All second degree AV blocks are the result of failure of the impulse
generated by the SA node to reach the AV node.
False
Temporary epicardial pacing requires that:<\/p>\n\n\n\n
Pacing wires are placed directly on the heart muscle by the
cardiothoracic surgeon during cardiac surgery.
On an ECG wave, ventricular depolarization is represented by:
QRS complex
The only category of drugs that can increase the risk of the Torsades de
pointes (TdP) are antidysrhythmic agents.
False
What bipolar lead is similar to V1?
Lead MCL1
You are caring for a 61 year old female that is status post inferior wall
myocardial infarction. She has received angioplasty of the right coronary
artery. You notice her rhythm is regular sinus rhythm with intermittent
pauses approximately the length of the 2-3 cardiac cycles. She is
asymptomatic at this time. It is determined to be sinus arrest. This is
most likely transient and is caused by all of the following except:
Chronic anemia
Which of the following is the rate for an accelerated junctional rhythm?
60-100 beats per minute
Which of the following are identified in Idioventricular Rhythm?
All of the above
Occasional Premature Ventricular Contractions are not uncommon, even
in healthy hearts. But if they increase in frequency, it can develop into a
life threatening emergency.
True
Which of the following is the rate for junctional tachycardia?
Greater than 100 beats per minute
