1. If a patient is experiencing ventricular fibrillation, what immediate intervention
should be prioritized to restore normal heart function?
Monitoring heart rate
Administration of beta-blockers
Increased fluid intake
Defibrillation
2. What does the PR interval indicate?
Depolarization of the atria
Repolarization of the ventricles
Atrial depolarization and the time for the impulse to travel from AV
node to ventricles
Depolarization of the ventricles
3. What is the primary purpose of transcutaneous pacing?
To stimulate heartbeats externally
To administer medication
To perform heart surgery
To monitor heart rhythm
4. If a patient with a pacemaker experiences symptoms of bradycardia despite
the device being functional, what could be a potential cause related to
oversensing?
, The pacemaker's battery may be low, causing it to malfunction.
The pacemaker may be oversensing electrical noise, interpreting it
as normal heart activity and failing to pace appropriately.
The pacemaker leads may be dislodged, preventing proper sensing.
The patient may have developed a new arrhythmia that the pacemaker
cannot detect.
5. What is the effect of a heart block:
plugs up the coronary arteries, depriving the heart muscle of oxygen
and nutrients, causing local cell death
blocks the atrio-ventricular conducting system, thus abolishing the
synchronization of atria and ventricles
causes the ventricles to become the overall heart "pacemaker"
would only operate in stress conditions
prevents the atria from contracting
6. If a patient presents with a ventricular rate of 120 bpm and exhibits
characteristics of a junctional rhythm, how would you classify their condition?
Normal sinus rhythm
Ventricular fibrillation
Junctional tachycardia
Atrial fibrillation
7. What is the maximum QRS duration for narrow complex supraventricular
tachycardia (NCSVT)?
0.10 seconds
, 0.08 seconds
0.12 seconds
0.15 seconds
8. What is the consequence of failure to sense in pacemaker function?
Decreased blood pressure
Inappropriate pacing spikes
Increased heart rate
Arrhythmias
9. What is the primary characteristic of a 3rd Degree Heart Block?
Complete dissociation between atrial and ventricular activity
Ventricular activity is faster than atrial activity
Increased heart rate
Regular atrial and irregular ventricular rhythms
10. What is the heart rate range that defines sinus tachycardia?
80-120 bpm
60-100 bpm
150-200 bpm
100-150 bpm
11. What is the primary function of P waves in an EKG?
Ventricular repolarization
Atrial depolarization
