Question 1:
Who is credited with the invention of the first practical pacemaker?
Explanation: The correct answer is A) Wilson Greatbatch. Wilson Greatbatch is credited with the invention of the first practical pacemaker. He developed the implantable pacemaker in the late 1950s, which revolutionized the treatment of irregular heart rhythms.
Question 2:
What is the primary function of a pacemaker?
Explanation: The correct answer is B) Maintaining heart rate. The primary function of a pacemaker is to maintain and regulate the heart rate. It delivers electrical impulses to the heart to ensure proper rhythm and coordination of the heart's contractions.
Question 3:
Where is a pacemaker typically implanted in the body?
Explanation: The correct answer is D) Chest. A pacemaker is typically implanted in the chest, near the collarbone. The leads of the pacemaker are threaded through a vein and positioned within the heart to deliver electrical signals.
Question 4:
Which type of pacemaker is capable of sensing the body's own electrical signals?
Explanation: The correct answer is B) Dual-chamber pacemaker. A dual-chamber pacemaker is capable of sensing the body's own electrical signals. It can monitor both the atrial and ventricular activity and deliver appropriate pacing impulses to maintain the optimal heart rhythm.
Question 5:
Which condition is commonly treated with a pacemaker?
Explanation: The correct answer is A) Arrhythmia. A pacemaker is commonly used to treat arrhythmia, a condition characterized by irregular heart rhythms. It helps regulate the heart's electrical activity, ensuring a consistent and proper heartbeat.
