Question 1

What’s Ventricular fibrillation (V-fib)

Answer 1

lethal rhythm that results in the quivering of the ventricles which leads to a rapid fall in cardiac output.

Question 2

What medications can be administered to a patient experiencing Ventricular fibrillation (V-fib) during a code resuscitation attempt?

Answer 2

Epinephrine

Amiodarone

Question 3

What’s coarse V-fib?

Answer 3

When the fibrillation is strong, the peaks are taller and the valleys are deeper.
It’s called “coarse” because the line is anything but smooth.

Question 4

What’s fine ventricular fibrillation

Answer 4

When the peaks and valleys are short and shallow.

It has a lower chance of successful resuscitation than coarse ventricular fibrillation. This is because the electrical activity in the heart is almost similar to asystole, which is hard to revive.

Question 5

The patient is unresponsive and has no pulse. What’s the nurses next step?

Answer 5

Start high-quality CPR, followed by defibrillation

Question 6

Torsades de pointes is known as a type of

Answer 6

polymorphic (NOT monomorphic) ventricular tachycardia.

Question 7

Torsades de pointes:
a potential cause for this rhythm…

Answer 7

Amiodarone
( cause a prolonged QT interval)

Question 8

patient is experiencing ventricular tachycardia, has no symptoms and a pulse is present:
Should be anticipated to be treated with..

Answer 8

Amiodarone IV

(maintain the normal rhythm.)

Question 9

Patient is experiencing ventricular tachycardia, unstable and demonstrating S/S related to decreased cardiac output. A pulse is present:
Should be anticipated to be treated with..

Answer 9

Synchronized cardioversion

Question 10

Monomorphic Vs. Polymorphic Ventricular Tachycardia.

Answer 10

VT is divided into monomorphic and polymorphic ventricular tachycardia.

Monomorphic VT is characterized by a single, stable QRS morphology with no beat-to-beat variation,

while polymorphic VT has beat-to-beat variation in QRS shape and multiple QRS morphologies

Question 11

What should be found in the rhythm for it to be considered Sinus Bradycardia

Answer 11

Regular atrial and ventricular rate

Atrial rate 40 and ventricular rate of 40

PR interval 0.14 seconds (should be b/w .12-.20)

QRS interval 0.08 seconds

One p wave present in front of every QRS complex

Question 12

Nurse action when ECG shows sinus bradycardia

Answer 12

Assess the patient.
When discovering sinus bradycardia, the nurse should determine if the patient is having symptoms.

Not all cases of this rhythm require medical treatment.

If needed, give atropine
If HR gets below 60BPM

Question 13

treatments for symptomatic sinus bradycardia?

Answer 13

Dopamine

Atropine
(1 mg IV push every 3-5 minutes, max dose of 3 mg)

• should not be used in a patient with a transplanted heart

Transcutaneous pacing

Epi infusion
