 Module 3 Quiz    

Question 1In the cardiac cycle, the right atrium fills first, then the left atrium.

True

False

Question 2Which statement is true?

Tachycardia will decrease cardiac output

Hypoxia can decrease cardiac output

The right atrium receives oxygenated blood from the lungs

Blood pressure is a measurement of systolic pressure/diastolic pressure

Question 3A consistent resting blood pressure of 120/88 would be considered:

Normal

Prehypertension

Stage 2 hypertension

Stage 1 hypertension

Question 4The “dub” sound (or S2) is created by:

The semilunar valves opening

The semilunar valves closing

The AV valves closing

The AV valves opening

Question 5Which statement is true regarding blood pressure?

The systolic pressure relates to the pressure in the blood vessels when the ventricles are not contracting.

Blood pressure doesn’t impact cardiac output.

Blood pressure can be influenced by body position and emotional states.

Diastolic pressure is higher than systolic in a healthy person.

Question 6The blood pressure of veins should always be slightly higher than arteries in a healthy person.

True

False

Question 7The cardiac conduction system causes the right atrium and right ventricle of the heart to contract at the same time, and then the left atrium and left ventricle contract at that same time?

True

False

Question 8Which of the following statements is true regarding the cardiac cycle?

The right atrium receives oxygenated blood from the body

The T wave on the EKG graph/measurement represents ventricular contraction

The left atrioventricular (AV) valve is commonly referred to as pulmonary valve

The ventricles contract at the same time

Question 9The thickest layer of an artery is the:

Tunica externa

Tunica interna

Tunica media

Endothelium

Question 10Bradycardia is characterized as a heart rate of less than 60 beats per minute.

True

False

Question 11Which statement is NOT true regarding the cardiac cycle?

The P wave on the EKG graph/measurement relates to atria going through the depolarization process

The right ventricle will pump blood out to the lungs so the red blood cells can become oxygenated

The heart valves allow one-way flow of blood through the heart

Systole relates to when the ventricles are not contracting

Question 12What statement is true regarding blood vessels?

Veins typically have a higher blood pressure than arteries

Veins typically carry oxygenated blood through the body

The endothelium is only found in arteries and veins

Nutrient, gas and product exchange only occurs in the capillaries

Question 13The SA node can influence cardiac output.

True

False

Question 14Which of the following is true of the cardiac output?

Cardiac output decreases substantially when exercising.

Cardiac output stays consistent throughout the day with little variation.

CO is equal to heart rate multiplied stroke volume.

CO is the volume of blood pumped from one ventricle in a span of one hour.

Question 15Blood flows from the elastic arteries to the ___ then ___.

Arterioles; muscular arteries

Venules; capillaries

Muscular arteries; arterioles

Capillaries; arterioles

Question 16The ventricles are contracting when the heart is in the systolic phase.

True

False

Question 17The thickest layer of large veins is the tunica externa.

True

False

Question 18Blood exiting the right ventricle flows through which valve?

Tricuspid

Pulmonary

Aortic

Mitral

Question 19What factor does NOT influence stroke volume?

High blood pressure

The amount of stretch or tension in the ventricle just before it contracts

The amount of blood that is filling up the ventricle

The oxygen levels in the blood  

Question 20The entire cardiac cycle is dependent upon the AV node generating the electrical impulse to start a heartbeat.

True

False

Question 21What statement is true regarding blood vessels?

The arteries typically carry oxygenated blood from away from the heart

The tunica interna contains the smooth muscle

Venules allow for nutrient, product, gas and waste exchange to occur between the body cells and blood vessels

The lumen of arteries is larger than that of veins.

Question 22Which of the following choices is the correct route of blood flow through the systemic circuit after leaving the heart?

Arterioles, arteries, capillaries, veins, venules

Arteries, capillaries, veins, venules, arterioles

Arteries, venules, capillaries, arterioles, veins

Arteries, arterioles, capillaries, venules, veins

Question 23Which of the following factors decreases stroke volume?

Sympathetic stimulation

Epinephrine

Hypoxia

Thyroid hormone

Question 24Which statement is true of blood vessels?

All arteries have valves to prevent backflow.

The blood pressure of the veins is equal to the blood pressure of the arteries in a healthy person.

Capillaries are the only type of vessel that allow exchange of gases and nutrients.

The tunica media of veins is thicker than the tunica media of arteries.

Question 25Which of the following statements is true?

The left atrium fills before the right atrium during every heartbeat.

Stroke volume is the amount of blood pumped from one ventricle in span of one minute.

An arteriole is classified as the largest type of artery.

Heart rate can influence cardiac output
