What is the primary function of an ECG (electrocardiogram) in diagnosing heart conditions?
Detecting physical blockages in the heart's arteries.
Recording the heart's electrical activity to identify rhythm abnormalities.
Providing a real-time, 3D image of the heart's chambers.
Measuring a patient's blood pressure and heart rate.
Which of the following statements correctly describes the difference between systole and diastole?
During systole, the ventricles fill with blood, and during diastole, blood is ejected from the heart.
Systole is the phase of the cardiac cycle when the heart is at rest, while diastole is when it contracts to pump blood.
Systole is related to the top number of a blood pressure reading, but diastole is not included in the reading.
Systole is the contraction phase when the heart pumps blood out, and diastole is the relaxation phase when the heart fills with blood.
A pulse oximeter determines a patient's pulse rate by analyzing:
The volume of venous blood flowing through the capillaries between heartbeats.
The temperature fluctuations on the skin's surface with each cycle of blood flow.
The change in light absorption caused by the pulsatile flow of blood with each heartbeat.
The ratio of red to infrared light absorbed by oxygenated versus deoxygenated hemoglobin.
Choose the statement/s that are true:
Ventricles are known as the upper chambers of the heart.
Valves are responsible for ensuring there is no backflow during delivery of blood.
Blood flows into the heart thru artery and blood flows out of the heart thru veins.
The smallest blood vessel is the capillaries.
What distinguishes Duplex Ultrasound from 2D Echocardiogram?
What is the purpose of a lead apron that is sometimes used during an X-ray?
To prevent the patient from moving during the scan.
To block X-ray radiation from reaching sensitive parts of the body.
To improve the quality of the image by adding weight.
To help the machine get a clearer image of bone.
What is the most critical function of the cardiovascular system?
To provide structural support for the body's organs.
To transport essential substances and remove waste products from cells.
To fight infections and diseases on its own.
