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:

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:

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
