Frage 8
Frage
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?
Frage 9
Frage
Individuals with atrial fibrillation are at increased risk of stroke because:
Antworten
-
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
Frage 10
Frage
Find the true statement:
Antworten
-
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

1st degree AV block
-
2nd degree AV block type 2
-
2nd degree AV block type 1
-
Sinus block (aka “skipped beat”)

Frage
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?

Antworten
-
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
