Understanding Blood Pressure and Heart Function

What is blood pressure?

• The electrical activity of the heart

• The hydrostatic pressure exerted by blood on the walls lining the heart and vessels

• The amount of blood pumped by the heart per minute

• The rate at which blood flows through the vessels

What is the term for the full contraction and relaxation of the heart?

• Systolic cycle

• Diastolic cycle

• Cardiac cycle

• Pulse cycle

During which phase of the cardiac cycle is systolic pressure measured?

• Ventricular relaxation

• Atrial contraction

• Ventricular contraction

• Atrial relaxation

What is the term for the pressure during ventricular relaxation?

• Systolic pressure

• Diastolic pressure

• Mean arterial pressure

• Pulse pressure

What instrument is used to measure blood pressure?

• Thermometer

• Stethoscope

• Sphygmomanometer

• Electrocardiogram

What are Korotkoff sounds?

• Sounds produced by the heart valves

• Sounds produced by the lungs during breathing

• Audible sounds produced when the pressure on the arteries is affected

• Sounds produced by the digestive system

How is pulse pressure (PP) calculated?

What does pulse pressure indicate?

• The average arterial pressure throughout one cardiac cycle

• The amount of blood forced from the heart during systole

• The total blood volume in the body

• The heart rate

What is mean arterial pressure?

• The difference between systolic and diastolic pressures

• The average arterial pressure throughout one cardiac cycle

• The maximum pressure in the arteries

• The minimum pressure in the arteries

How is the apical pulse measured?

• By counting the pulses in the radial artery

• By listening to the heartbeats using a stethoscope over the heart

• By measuring the blood pressure

• By using an electrocardiogram
