Question 1

What is the term for heartbeats that occur outside the normal rhythm?

Accepted Answer

Ectopic beats refer to heartbeats that occur outside the normal rhythm, such as premature ventricular contractions (PVCs) or premature atrial contractions (PACs). Murmur refers to an abnormal heart sound, bruit refers to an abnormal sound heard in blood vessels, and diaphoresis refers to excessive sweating.

Question 2

What is the term for a noncancerous tumor of the blood vessels?

Accepted Answer

The term for a noncancerous tumor of the blood vessels is hemangioma.

Question 3

The sensation or urge to vomit is called

Accepted Answer

Nausea refers to the sensation of feeling like you are about to vomit.

Question 4

Extremely rapid and irregular heart contractions are called

Accepted Answer

Extremely rapid and irregular heart contractions are characteristic of fibrillation. Bundle branch block, sick sinus syndrome, and flutter are all cardiac rhythm abnormalities but do not necessarily involve rapid and irregular contractions.

Question 5

The term for heart pain is

Accepted Answer

The term for heart pain is cardialgia.

Question 6

Another term for vomit is

Accepted Answer

The term "emesis" is another word for vomiting.

Question 7

Low blood pressure upon rising to a standing position is called

Accepted Answer

Low blood pressure upon rising to a standing position is known as orthostatic hypotension. Choices A, B, and D refer to other conditions (cardiodynia means heart pain, diaphoresis means excessive sweating, and cyanosis means bluish discoloration of the skin due to lack of oxygen).

Question 8

Blockage of blood flow to the extremities is called

Accepted Answer

Blockage of blood flow to the extremities is called peripheral arterial occlusion. Septal defect is a type of congenital heart defect, pallor refers to paleness of the skin due to reduced blood flow, and pulmonary congestion is the accumulation of fluid in the lungs.

Question 9

The condition in which a person must sit or stand to breathe comfortably is called

Accepted Answer

Orthopnea is a condition in which a person finds it difficult to breathe while lying down and must sit or stand to breathe comfortably. Eupnea refers to normal breathing, pulmonary congestion is the accumulation of fluid in the lungs, and diaphoresis is excessive sweating.

Question 10

Abnormal accumulation of fluid in interstitial spaces of tissues is called

Accepted Answer

Abnormal accumulation of fluid in interstitial spaces of tissues is called edema.

Question 11

What is the term for a benign growth in the interatrial septum?

Accepted Answer

Atrial myxoma is a benign tumor that arises from the interatrial septum, typically in the left atrium. The tumor is composed of myxoid (mucinous) material and can cause symptoms such as dyspnea, chest pain, and palpitations, as well as embolic events if pieces of the tumor break off and travel through the bloodstream.

Question 12

Narowing of the valve between the left atrium and left ventricle is called

Accepted Answer

The narrowing of the valve between the left atrium and left ventricle is called mitral stenosis. Mitral valve prolapse refers to the mitral valve leaflets bulging back into the left atrium during systole. Aortic stenosis is the narrowing of the aortic valve. Tricuspid stenosis is the narrowing of the valve between the right atrium and right ventricle.

Question 13

Difficult and/or painful breathing is called

Accepted Answer

Dyspnea is the term for difficult and/or painful breathing. Diaphoresis refers to excessive sweating, pulmonary congestion is the accumulation of fluid in the lungs, and syncope is a temporary loss of consciousness due to a drop in blood pressure.

Question 14

An excessive amount of blood in vessels of the lungs is called

Accepted Answer

Pulmonary congestion refers to an excessive amount of blood in the vessels of the lungs, which can lead to difficulty breathing (dyspnea) and trouble breathing when lying down (orthopnea). Edema refers to the accumulation of fluid in tissues, while dyspnea and orthopnea are symptoms of pulmonary congestion.

Question 15

A rare cancer of the cells that line the blood vessels is

Accepted Answer

Hemangiosarcoma is a rare cancer that develops from the cells that line blood vessels. The other options (cardiac myxosarcoma, hemangioma, and atrial myxoma) are all different types of heart tumors, but not associated with blood vessel linings.

Question 16

A rapid heartbeat is called

Accepted Answer

Tachycardia is defined as a rapid heartbeat, typically over 100 beats per minute. Palpitation refers to an awareness of one's own heartbeat, but not necessarily a rapid one. Bradycardia is a slow heartbeat, typically under 60 beats per minute. Palpation refers to the act of examining a part of the body by touch.

Question 17

A rare heart cancer originating in the left atrium is

Accepted Answer

The answer of A rare heart cancer originating in the...

Question 18

Paleness of skin and/or mucous membranes is

Accepted Answer

Paleness of skin and/or mucous membranes is called pallor. Edema is swelling due to excess fluid accumulation in tissues, a thrill is a vibrating sensation felt upon palpation of an artery, and cyanosis is bluish discoloration of the skin and mucous membranes due to decreased oxygen levels in the blood.

Question 19

Narrowing of the valve between the right atrium and right ventricle is called

Accepted Answer

Narrowing of the valve between the right atrium and right ventricle is called tricuspid stenosis. Aortic stenosis is narrowing of the valve between the left ventricle and the aorta, bicuspid stenosis is narrowing of the valve between the left atrium and left ventricle, and mitral valve prolapse is a condition in which the valve between the left atrium and left ventricle doesn't close properly.

Question 20

Protrusion of one or both cusps of the mitral valve back into the left atrium is called

Accepted Answer

Protrusion of one or both cusps of the mitral valve back into the left atrium is called mitral valve prolapse. A is incorrect because valvulitis refers to inflammation of the heart valve, and B is incorrect because VSD refers to a ventricular septal defect, a condition where there is a hole in the wall separating the two lower chambers of the heart. D is incorrect because mitral stenosis refers to a narrowing of the mitral valve opening, which impedes blood flow from the left atrium to the left ventricle.
