Question 1

A ________ pacemaker is one where a lead wire is inserted through the skin and threaded into a large vein leading into the right side of the heart.
A) transcutaneous
B) transvenous
C) subcutaneous
D) substernal

Accepted Answer

A transvenous pacemaker is inserted through the skin and threaded into a large vein leading into the right side of the heart, while a transcutaneous pacemaker is applied externally to the chest wall. A subcutaneous pacemaker is implanted under the skin, but not threaded into a vein, and a substernal pacemaker is placed below the sternum. Therefore, the best choice is B, transvenous.

Question 2

The pacemaker that consists of two large electrode pads connected to a cardiac monitor that conduct electrical impulses through the skin to the heart is termed a ________ pacemaker.
A) transcutaneous
B) substernal
C) permanent
D) subcutaneous

Accepted Answer

The description matches that of a transcutaneous pacemaker, which uses external electrode pads to transmit electrical impulses through the skin to initiate or regulate cardiac contractions. The other options are not accurate descriptions of this type of pacemaker.

Question 3

A ________ pacemaker is when a pacemaker develops a rapid rate of electrical impulse discharge and can reach a rate of 200 to 300 BPM.
A) runaway
B) sensing
C) failed
D) sequential

Accepted Answer

A runaway pacemaker is when the electrical impulse discharge from the pacemaker becomes too rapid, causing the heart to beat too quickly. This can result in symptoms such as palpitations, dizziness, and fainting. It is important to address and correct a runaway pacemaker as soon as possible to prevent further complications.

Question 4

The equipment with pacemakers that relays the electrical impulse to the myocardium is the:
A) pacer spike.
B) generator.
C) lead wires.
D) QRS interval.

Accepted Answer

Lead wires are the equipment that relays the electrical impulse to the myocardium. Pacer spike is a visual marker on an ECG indicating the delivery of an electrical impulse from a pacemaker. The generator is the power source of the pacemaker. QRS interval is a part of the ECG that represents ventricular depolarization.

Question 5

The type of permanent pacemaker that has a lead wire inserted into the right atrium and the first impulse stimulates the atrium is a(n) ________ pacemaker.
A) septal
B) AV sequential
C) ventricular
D) atrial

Accepted Answer

A pacemaker with a lead wire inserted into the right atrium and first impulse stimulating the atrium is an atrial pacemaker.

Question 6

The capability of a pacemaker to recognize inherent electrical conduction system activity is termed:
A) capture.
B) sensing.
C) failure.
D) stimulation.

Accepted Answer

Sensing refers to the pacemaker's ability to detect the heart's intrinsic electrical activity. Capture refers to the pacemaker's ability to deliver an electrical impulse to the heart and cause it to contract. Failure refers to a malfunction of the pacemaker. Stimulation refers to the pacemaker's ability to deliver an electrical impulse to the heart.

Question 7

The ________ pacemaker is programmed to deliver electrical impulses at a constant selected rate.
A) asynchronous
B) synchronous
C) demand
D) automated

Accepted Answer

An asynchronous pacemaker delivers electrical impulses at a constant rate, regardless of the heart's natural activity.

Question 8

A device that substitutes for the normal pacemaker cells of the heart's electrical conduction system is a(n):
A) artificial pacemaker.
B) universal pacemaker.
C) central pacemaker.
D) voluntary pacemaker.

Accepted Answer

An artificial pacemaker is a device that substitutes for the normal pacemaker cells of the heart's electrical conduction system. It is used to regulate the heartbeat in individuals with certain heart conditions such as bradycardia (abnormally slow heart rate) or atrial fibrillation.

Question 9

When implementing transcutaneous pacing, the rate is commonly set in the range of:
A) 10-20 BPM.
B) 20-40 BPM.
C) 40-60 BPM.
D) 60-80 BPM.

Accepted Answer

Transcutaneous pacing is typically set at a rate of 60-80 beats per minute (BPM) to ensure adequate cardiac output and patient stability.

Question 10

Transcutaneous pacemakers can be used to treat all EXCEPT symptomatic:
A) bradycardia.
B) complete heart block.
C) ventricular tachycardia.
D) second-degree block.

Accepted Answer

Transcutaneous pacemakers are not typically used to treat ventricular tachycardia as it is a potentially life-threatening arrhythmia that requires more aggressive interventions such as defibrillation or antiarrhythmic drugs. Transcutaneous pacemakers are more commonly used to treat bradycardia, complete heart block, and certain types of second-degree block.

Question 11

The equipment with pacemakers that controls the rate and strength of each electrical impulse is the:
A) lead wires.
B) generator.
C) pads.
D) spike.

Accepted Answer

The generator is the equipment with a pacemaker that controls the rate and strength of each electrical impulse. Lead wires connect the generator to the heart, pads are used to secure the lead wires to the skin, and a spike is a sharp tool used to puncture medication vials.

Question 12

The type of permanent pacemaker where the lead wire is inserted into the right ventricle is a(n) ________ pacemaker.
A) ventricular
B) AV sequential
C) atrial
D) septal

Accepted Answer

In a ventricular pacemaker, the lead wire is inserted into the right ventricle to stimulate the ventricles to contract and maintain a regular heartbeat. The other options (AV sequential, atrial, septal) refer to different types of pacemakers that involve different placement of the lead wire and different pacing strategies.

Question 13

Pacemakers that are used to sustain a patient's heart rate in emergent situations are ________ pacemakers.
A) permanent
B) temporary
C) aggressive
D) superficial

Accepted Answer

Pacemakers used in emergent situations are temporary as they are not meant for long-term use and are only used until the patient's heart rhythm stabilizes or until a permanent pacemaker can be implanted.

Question 14

The EKG wave that is produced by an artificial pacemaker is a:
A) generator.
B) QRS.
C) PR interval.
D) spike.

Accepted Answer

The spike on an EKG represents the electrical impulse generated by an artificial pacemaker.

Question 15

The type of permanent pacemaker that has two lead wires, one in the right atrium and one in the right ventricle, is a(n) ________ sequential pacemaker.
A) AA
B) VV
C) AV
D) VA

Accepted Answer

An AV sequential pacemaker is a type of permanent pacemaker that has two lead wires - one in the right atrium and one in the right ventricle. It is designed to stimulate both chambers of the heart in a particular sequence, which can improve heart function in some patients with certain types of heart block or other cardiac conditions. The other options (AA, VV, VA) do not accurately describe a pacemaker with leads in both the atrium and ventricle.

Question 16

________ is noted by the presence of a spike and wide QRS complexes on the EKG monitor and/or rhythm strip.
A) Standardization
B) Release
C) Capture
D) Synchronous

Accepted Answer

The presence of a spike and wide QRS complexes on the EKG monitor and/or rhythm strip indicates capture, which refers to the ability of an electrical impulse to stimulate cardiac cells and cause a depolarization. This is often seen in patients with pacemakers or during electrical cardioversion. Standardization refers to making sure the EKG machine is calibrated correctly, release is not a term used in relation to EKGs, and synchronous refers to the coordination of electrical activity in the heart's chambers.

Question 17

When the artificial pacemaker does not depolarize the specified chamber or chambers of the heart and is denoted by the presence of a pacemaker spike not flowed by a QRS, this is referred to as failure to:
A) energize.
B) stimulate.
C) generate.
D) capture.

Accepted Answer

Failure to capture occurs when the pacemaker spike is present, indicating that the artificial pacemaker is sending an electrical signal, but there is no corresponding cardiac response (QRS complex). This means that the pacemaker is not successfully "capturing" the heart muscle to depolarize and cause contraction.

Question 18

Pacemakers that are implanted most often in a patient's upper chest and are left in place are ________ pacemakers.
A) transvenous
B) substernal
C) temporary
D) Permanent

Accepted Answer

Permanent pacemakers are implanted most often in a patient's upper chest and are left in place. Transvenous pacemakers are inserted through a vein and are temporary. Substernal pacemakers are surgically implanted below the collarbone and are not as common. Temporary pacemakers are used in emergency situations and are not left in place.

Question 19

The type of pacemaker that is programmed to generate an electrical impulse when the patient's heart rate falls below a predetermined rate is called:
A) synchronous.
B) asynchronous.
C) automated.
D) semi-automated.

Accepted Answer

A synchronous pacemaker is programmed to generate an electrical impulse when the patient's heart rate falls below a predetermined rate. This type of pacemaker is designed to synchronize with the patient's natural heartbeat and stimulate the heart when needed to maintain a regular rhythm. Asynchronous pacemakers, on the other hand, generate an electrical impulse regardless of the patient's natural heartbeat and are typically used for patients with complete heart block. Automated and semi-automated are not commonly used terms to describe pacemaker types.
