Respuesta
-
S1
-
S4
-
S3
-
S2
Pregunta 6
Pregunta
All of the following cause splits except:
Respuesta
-
Bundle branch block
-
Ventral septal defect
-
Irritable foci
-
Valve dysfunction or blood flow alterations
Pregunta 7
Pregunta
You are listening to a 6 y/o female heart beat and notice the rate increases with inspiration and decreases with expiration. She has no other s/s. What do you do?
Respuesta
-
Nothing, this can be a normal finding for this age
-
Administer nitroglycerin tablets to the patient
-
Immediately transport the patient to the ER
-
Stop treatment and reschedule for another day
Pregunta 8
Pregunta
A patient’s ECG shows a PR interval < 0.12 and a regular QRS rate > 100. The patient presents with a rapid and regular pulse and decreased cardiac output. This patient has what type of arrhythmia?
Respuesta
-
Wandering atrial pacemaker
-
Atrial premature beat
-
Atrial tachycardia
-
Atrial flutter
Pregunta 9
Pregunta
Individuals with atrial fibrillation are at increased risk of stroke because:
Respuesta
-
There is less blood supply to the brain
-
The heart is weaker
-
The vibrations inhibit vitamin K binding for the coagulation cascade
-
There is less atrial kick leading to blood being left behind in the atria to form a clot
Pregunta 10
Pregunta
Find the true statement:
Respuesta
-
Multifocal premature ventricular contractions look the same as bigeminy and come from the same spot
-
Ventricular premature contractions always require treatment
-
Patients with a ventricular premature contraction may have a pause in pulse followed by a strong beat or may complain of palpitations or skipped beats
-
Ventricular premature contractions more than 6 per minute or more than 3 in a row are no cause for concern
Pregunta 11
Pregunta
A patient in the hospital complains of heart palpitations, dyspnea, dizziness, and appears anxious and is sweating. This patient is experiencing:
Respuesta
-
Ventricular premature contraction
-
Ventricular tachycardia
-
Ventricular fibrillation
-
asystole
Pregunta 12
Pregunta
What is the correct order of progression?
Respuesta
-
Ventricular premature contraction (> 3 in a row), ventricular fibrillation, asystole, ventricular tachycardia
-
Ventricular tachycardia, quadrigeminy, ventricular fibrillation, asystole
-
Bigeminy, ventricular fibrillation, ventricular tachycardia, asystole
-
Ventricular premature contraction (> 3 in a row), ventricular tachycardia, ventricular fibrillation, asystole
Pregunta 13
Pregunta
Fixed P-R interval with a dropped QRS every third beat, may drop several QRS waves in a row, typically fixed with a pacemaker. Identify the arrhythmia:
Respuesta
-
1st degree AV block
-
2nd degree AV block type 2
-
2nd degree AV block type 1
-
Sinus block (aka “skipped beat”)
Pregunta 14
Pregunta
ECG presents as regular P and QRS waves that appear out of sync with each other. s/s include slow HR (< 60 bpm), drop in CO, and possible ventricular fibrillation. What arrhythmia may proceed this type of block?
Respuesta
-
2nd degree AV block type 2
-
2nd degree AV block type 1
-
1st degree AV block
-
Left bundle branch block
Pregunta 15
Pregunta
You are seeing a 65 y/o male. Upon reading the ECG you notice he has a widened Q wave and an elevated ST wave on leads V1 and V2. What do you do?
Respuesta
-
Ask the patient if he has had any ischemic heart attacks recently
-
Do not perform treatment and reschedule for another day
-
Do nothing and treat him like any other patient
-
Verify with nursing or the doctor to see if they are aware that this patient has had an MI
