Question 1

Match the following terms with their descriptions below.
-Arrest of bleeding

Accepted Answer

Hemostasis is the process that causes bleeding to stop, meaning it is the arrest of bleeding.

Question 2

Match the following terms with their descriptions below.
-Simple protein that is combined with lipids; a high level of these lipoproteins is desirable

Accepted Answer

High-density lipoproteins are the simple proteins that combine with lipids, and a high level of these lipoproteins is desirable for maintaining good cardiovascular health. Digitalization is a medical treatment for heart conditions using digitalis medications. Homeostasis refers to the body's ability to maintain a stable internal environment. Hemostasis is the process of blood clotting to prevent excessive bleeding. Low-density lipoproteins are molecules that carry cholesterol through the bloodstream, but high levels of these lipoproteins can increase the risk of heart disease.

Question 3

Match the following terms with their descriptions below.
-State of equilibrium in the internal environment of the body

Accepted Answer

Homeostasis refers to the state of equilibrium in the internal environment of the body, where various physiological processes work to maintain a stable and balanced internal environment. Digitalization refers to the conversion of analog information into digital format. Hemostasis refers to the process of stopping bleeding. High-density lipoproteins (HDL) are a type of cholesterol that is "good" for the body, as it helps remove excess cholesterol from the bloodstream. Low-density lipoproteins (LDL) are a type of cholesterol that is "bad" for the body, as it contributes to the buildup of plaque in arteries.

Question 4

Match the following terms with their descriptions below. Some choices will be used more than once.
-Affect coronary conduction centers to increase or decrease heart rate or to convert rate to normal sinus rhythm

Accepted Answer

Antidysrhythmics affect the coronary conduction centers to either increase or decrease heart rate or to convert an abnormal rhythm to a normal sinus rhythm. Cardiac glycosides, antianginal medications, and calcium channel blockers may affect the heart rate and rhythm to some extent, but their primary actions are different.

Question 5

Match the following terms with their descriptions below.
-Increase or decrease in heart rate

Accepted Answer

The chronotropic effect refers to changes in heart rate. An increase in heart rate is a positive chronotropic effect, while a decrease is a negative chronotropic effect.

Question 6

Match the following terms with their descriptions below. Some choices will be used more than once.
-Cause vasodilation of the coronary arteries

Accepted Answer

Calcium channel blockers cause vasodilation of the coronary arteries, which in turn increases blood flow and oxygen delivery to the heart muscle. This helps to relieve angina symptoms and can be useful in treating hypertension and other cardiovascular conditions. Cardiac glycosides are a type of medication used to strengthen the heart muscle and improve its pumping efficiency. Antidysrhythmics are medications used to treat irregular heart rhythms, while antianginal medications are drugs used to prevent or relieve chest pain (angina) caused by reduced blood flow to the heart.

Question 7

Match the following terms with their descriptions below.
-Rapid dosing of digitalis to reach a therapeutic level

Accepted Answer

Digitalization refers to rapid dosing of digitalis to reach a therapeutic level.

Answer: B
 Homeostasis refers to maintaining a stable internal environment within the body.

Answer: C
 Hemostasis refers to the process of stopping bleeding.

Answer: D
 High-density lipoproteins are often referred to as "good" cholesterol because they help remove cholesterol from the bloodstream, thus reducing the risk of heart disease.

Answer: E
 Low-density lipoproteins are often referred to as "bad" cholesterol because they can build up in the arteries and increase the risk of heart disease.

Question 8

Match the following terms with their descriptions below.
-Increase or decrease in the force of myocardial contraction

Accepted Answer

Inotropic effect refers to the increase or decrease in the force of myocardial contraction.

Answer: A
 Chronotropic effect refers to the increase or decrease in heart rate.

Answer: C 
 Dromotropic effect refers to the increase or decrease in atrioventricular (AV) node conduction velocity.

Answer: D 
 Intermittent claudication refers to leg pain, cramping, or fatigue that occurs during exercise and is relieved with rest.

Answer: E 
 Automaticity refers to the ability of certain cells in the heart to generate electrical impulses without external stimuli.

Question 9

Match the following terms with their descriptions below. Some choices will be used more than once.
-Effective on the coronary arteries to lessen the work of the heart

Accepted Answer

Antianginal medications are effective on the coronary arteries to lessen the work of the heart. Cardiac glycosides are used to increase the force of myocardial contractions, antidysrhythmics are used to treat and prevent abnormal heart rhythms, and calcium channel blockers are used to lower blood pressure and decrease the workload of the heart.

Question 10

Match the following terms with their descriptions below.
-Increase or decrease in the heart's conduction of electrical impulses

Accepted Answer

The dromotropic effect refers to the increase or decrease in the heart's conduction of electrical impulses, affecting the speed at which the heart's electrical system conducts.

Question 11

Match the following terms with their descriptions below.
-Drop in blood pressure experienced when a person changes from supine to upright position

Accepted Answer

Orthostatic hypotension refers to the temporary drop in blood pressure that occurs when a person changes from lying down or sitting to a standing position. Embolus and thrombus refer to blood clots that can cause blockages in blood vessels. Hypertension refers to high blood pressure, while thromboembolism refers to a blockage of a blood vessel by a blood clot that has broken off from its original site.

Question 12

Match the following terms with their descriptions below.
-Obstruction of a blood vessel by a foreign substance or a blood clot

Accepted Answer

A thrombus is a blood clot that forms within a blood vessel and obstructs blood flow.

Question 13

Match the following terms with their descriptions below.
-Simple proteins that are combined with lipids; a high level of these lipoproteins is undesirable

Accepted Answer

Low-density lipoproteins (LDL) are simple proteins combined with lipids, and a high level of LDL is considered undesirable because it can lead to plaque buildup in arteries, increasing the risk of heart disease and stroke.

Question 14

Match the following terms with their descriptions below.
-Automatic spontaneous initiation of a heart impulse

Accepted Answer

Automaticity refers to the ability of cardiac cells to generate spontaneous electrical impulses.

Answer: A 
 Chronotropic effect refers to the effect of a drug or intervention on the heart rate.

Answer: B 
 Inotropic effect refers to the effect of a drug or intervention on the strength of the heart's contractions.

Answer: C 
 Dromotropic effect refers to the effect of a drug or intervention on the conduction of electrical impulses through the heart.

Thromboembolism is the blockage of a blood vessel by a detached embolus, which is often a blood clot or thrombus that has traveled from another part of the body.

Question 17

Match the following terms with their descriptions below.
-Elevation of blood pressure above normal limits

Accepted Answer

Hypertension is the elevation of blood pressure above normal limits. Embolus and thrombus both refer to a blood clot, but a thrombus remains in place while an embolus travels through the circulatory system. Thromboembolism is a combination of the two, referring to a blood clot that travels to another part of the body. Orthostatic hypotension is a drop in blood pressure upon standing up.
