CTE PBS 4.2 review

Which of the following is a measure of the electrical activity in the heart?

• blood pressure

• heart rate

• electrocardiogram (EKG)

• biopsy

What is the effect of narrowed arteries on a person's blood flow and pressure?

• increased blood flow and increased pressure

• increased blood flow and decreased pressure

• decreased blood flow and increased pressure

• decreased blood flow and decreased pressure

A person has a blood pressure of 145/90 mmHg. How would you categorize their blood pressure?

• normal range

• prehypertension

• hypertension

• hypotension

The correct pathway for the conduction of an electrical signal through the heart is:

• SA node, AV node, AV bundle, Purkinje fibers, bundle branches

• AV node, SA node, AV bundle, bundle branches, Purkinje fibers

• SA node, AV node, bundle branches, AV bundle, Purkinje fibers

• SA node, AV node, AV bundle, bundle branches, Purkinje fibers

Which of the following is the measure of the number of times the heart beats in a minute?

• blood pressure

• electrocardiogram (EKG)

• heart rate

• biopsy

Which structure is the pacemaker of the heart?

• sinoatrial (SA) node

• right atrium

• right ventricle

• atrioventricular (AV) node

Normal blood pressure is

• 80/140mmHg

• 140/90mmHg

• 120/80mmHg

• 80/120mmHg

The QRS correlates with which event?

• atrium contraction/ signals moving from SA node to AV node

• ventricle repoloarization

• ventricle contraction

• both atrial and ventricle contraction

A pulse is detected by feeling the movement of blood through a/an

• vein

• artery

• valve

• ventricle

The pulse felt in your neck

• coronary

• brachial

• radial

• carotid
