Questions and Answers
- 1.
AF is an abbreviation for
- A.
A. atrial filter
- B.
B. atrial focus
- C.
C. atrial fibrillation
- D.
D. auto focus
Correct Answer
C. C. atrial fibrillationExplanation
AF is an abbreviation for atrial fibrillation, which is a heart condition characterized by irregular and rapid heartbeats. This condition occurs when the electrical signals in the upper chambers of the heart (atria) are chaotic and cause the heart to beat in an irregular rhythm. Atrial fibrillation can lead to various symptoms such as palpitations, shortness of breath, dizziness, and chest pain. It is a serious condition that increases the risk of stroke and other heart-related complications. Treatment options for atrial fibrillation include medication, lifestyle changes, and medical procedures like cardioversion or ablation.Rate this question:

Adhesion means the ability to
- A.
A. attach
- B.
B. sit on top
- C.
C. cut through
- D.
D. separate itself
Correct Answer
A. A. attachExplanation
Adhesion refers to the ability of a substance or material to attach or stick to another surface. It is the force that holds two different materials together when they come into contact. This can occur at a molecular level, where the molecules of one substance adhere to the molecules of another substance. Adhesion is essential in various processes and applications, such as gluing objects together, painting, and even in biological systems where cells adhere to each other or to surfaces. Therefore, the correct answer is "a. attach".Rate this question:

occur(s) when heart muscle cannot get oxygen and the tissue dies
- A.
A. Paroxysmal tachycardia
- B.
B. Myocardial infarction
- C.
C. Cardiac palpitations
- D.
D. Myocarditis
Correct Answer
B. B. Myocardial infarctionExplanation
Myocardial infarction occurs when the heart muscle cannot get enough oxygen and the tissue dies. This is commonly known as a heart attack. During a heart attack, a blockage in the coronary arteries prevents blood flow to the heart muscle, leading to tissue damage and possibly death if not treated promptly. Paroxysmal tachycardia refers to episodes of rapid heartbeat, cardiac palpitations refer to the awareness of one's own heartbeat, and myocarditis refers to inflammation of the heart muscle. None of these conditions specifically involve the death of heart tissue due to lack of oxygen.Rate this question:

A. a negative deflection
- B.
B. a positive deflection
- C.
C. electronic noise
- D.
D. equiphasic or isoelectric complexes
Correct Answer
D. D. equiphasic or isoelectric complexesExplanation
When a depolarization wavefront moves perpendicular to a positive electrode, it creates equiphasic or isoelectric complexes on the ECG. This means that there will be no significant deflection in either the positive or negative direction. The wavefront moving perpendicular to the positive electrode results in equal positive and negative charges being detected, resulting in an isoelectric or equiphasic complex on the ECG.Rate this question:

B. arteriostenosis
- C.
C. arteriosclerosis
- D.
D. arteriostenosis
Correct Answer
C. C. arteriosclerosisExplanation
Arteriosclerosis is the correct answer because it refers to the hardening and thickening of the arteries. This condition occurs when plaque builds up on the artery walls, causing them to become stiff and less flexible. This can lead to reduced blood flow and increased risk of heart disease and other cardiovascular problems. Cardiac stasis, arteriostenosis, and arteriostenosis are not accurate terms for describing the hardening of the arteries.Rate this question:

D. arrhythmia
Correct Answer
D. D. arrhythmiaExplanation
An abnormal rhythm of the heart is called arrhythmia. This term refers to any irregularity or abnormality in the electrical impulses that regulate the heartbeat. It can cause the heart to beat too fast, too slow, or in an irregular pattern. Arrhythmias can be harmless or life-threatening, and they can be caused by various factors such as heart disease, medications, or electrolyte imbalances. It is important to diagnose and treat arrhythmias to prevent complications and ensure proper heart function.Rate this question:
