#1
Which component of a cardiac rhythm management device detects abnormal heart rhythms?
Sensor
ExplanationThe sensor component in a cardiac rhythm management device detects abnormal heart rhythms for prompt intervention.
#2
What is the primary function of a pacemaker in cardiac rhythm management?
To regulate heart rhythm
ExplanationThe primary function of a pacemaker is to regulate heart rhythm by sending electrical impulses to the heart when needed.
#3
What is the primary purpose of the battery in a cardiac rhythm management device?
To power the device
ExplanationThe battery in a cardiac rhythm management device serves the primary purpose of powering the device.
#4
What is the purpose of the lead in a cardiac rhythm management device?
To deliver therapy
ExplanationThe lead in a cardiac rhythm management device is responsible for delivering therapy, such as electrical impulses or shocks, to the heart.
#5
What is the purpose of the pulse generator in a cardiac rhythm management device?
To deliver therapy and store data
ExplanationThe pulse generator in a cardiac rhythm management device delivers therapy (such as pacing) and stores data related to the device's function.
#6
What is the typical location for implanting a cardiac rhythm management device?
Chest
ExplanationThe typical location for implanting a cardiac rhythm management device is the chest.
#7
Which type of cardiac rhythm management device is primarily used for patients with bradycardia?
Pacemaker
ExplanationPacemakers are primarily used for patients with bradycardia to maintain a normal heart rate.
#8
What is the purpose of Cardiac Resynchronization Therapy (CRT) in cardiac rhythm management?
To synchronize heartbeats
ExplanationCRT is used to synchronize heartbeats, especially in patients with heart failure and conduction delays.
#9
What is the purpose of an Implantable Cardioverter Defibrillator (ICD) in cardiac rhythm management?
To prevent sudden cardiac arrest
ExplanationICDs are designed to prevent sudden cardiac arrest by delivering high-energy shocks to terminate life-threatening arrhythmias.
#10
Which condition might require the use of an Implantable Cardioverter Defibrillator (ICD)?
Ventricular fibrillation
ExplanationICDs are used for conditions like ventricular fibrillation, where rapid, chaotic heartbeats can be life-threatening.
#11
What is the purpose of remote monitoring in cardiac rhythm management?
To allow healthcare providers to monitor device function
ExplanationRemote monitoring enables healthcare providers to monitor the function of cardiac rhythm management devices without the need for in-person visits.
#12
What is the typical lifespan of the battery in a cardiac rhythm management device?
5-7 years
ExplanationThe typical lifespan of the battery in a cardiac rhythm management device is 5-7 years, after which it needs replacement.
#13
In which chamber of the heart are leads typically placed in a cardiac rhythm management device?
Right ventricle
ExplanationLeads in a cardiac rhythm management device are typically placed in the right ventricle of the heart.
#14
Which of the following is a potential complication associated with implanting cardiac rhythm management devices?
Increased risk of infection
ExplanationImplanting cardiac rhythm management devices carries the potential complication of an increased risk of infection.
#15
Which of the following is a feature of Magnetic Resonance Imaging (MRI)-compatible cardiac rhythm management devices?
They do not interfere with MRI scans
ExplanationMRI-compatible cardiac rhythm management devices are designed not to interfere with MRI scans, allowing patients to undergo imaging procedures safely.
#16
Which of the following is a potential complication of lead placement in cardiac rhythm management devices?
Lead dislodgement
ExplanationLead dislodgement is a potential complication associated with the placement of leads in cardiac rhythm management devices.
#17
What is the purpose of the atrial lead in a dual-chamber pacemaker?
To sense atrial activity
ExplanationThe atrial lead in a dual-chamber pacemaker is used to sense atrial activity and coordinate pacing between the atria and ventricles.
#18
What is the primary function of the lead insulation in a cardiac rhythm management device?
To prevent infections
ExplanationLead insulation in a cardiac rhythm management device serves the primary function of preventing infections at the lead site.
