Cardiovascular and Blood Disorders Quiz 4

Benjamin and Oliver were discussing about their grandfather's health condition. Benjamin mentioned that their grandfather was diagnosed with angina. Oliver, not being familiar with the term, asked Benjamin, 'What is angina?'

• It's a chest pain caused by low blood sugar

• It's a chest pain caused by lack of oxygen-rich blood to the heart

• It's a chest pain caused by a bacterial infection

• It's a chest pain caused by a blood clot in the lungs

Ethan, Aria, and Zoe are studying the human body in their biology class. They learned about the heart and its functions. Ethan asked, 'What is cardiac output?'

• The amount of blood pumped by the heart in one minute

• The amount of oxygen in the blood

• The electrical activity of the heart

• The force of the heart's contractions

Nora, Anika, and Zoe are studying for their biology exam. They come across a term 'ejection fraction'. Anika thinks it's the percentage of blood ejected from the heart's left ventricle with each contraction. Who among them is correct?

• Anika: The percentage of blood ejected from the heart's left ventricle with each contraction

• Nora: The amount of blood pumped by the heart in one minute

• Zoe: The strength or force of the heart's contractions

• None of them

Ava, Priya, and Harper are studying for their biology exam. They come across a question in their textbook: 'What does an EKG/ECG measure in a patient's body?'

• Blood pressure

• Blood sugar levels

• Electrical activity of the heart

• Oxygen levels in the blood

James is a medical student studying cardiology. He came across a term 'echocardiogram' in his textbook. Can you help him understand what an echocardiogram is?

• A test to measure blood flow in the arteries

• A test to measure lung function

• A test to measure brain activity

• A test to create images of the heart's structure and function using sound waves

During a biology class, Benjamin and Avery were studying the human heart. Their teacher, Scarlett, showed them an EKG/ECG and asked, 'What does the PQRST acronym represent in this EKG/ECG?'

• Different types of heart diseases

• Different stages of the heart's electrical cycle

• Different types of heart medications

• Different types of heart surgeries

Hannah, Grace, and Evelyn are studying the human heart in their biology class. They learned about the SA node and its functions. According to their study, what is the function of the SA node in the heart?

• To regulate blood pressure

• To generate electrical impulses and regulate heart rhythm

• To filter blood in the kidneys

• To produce red blood cells

Kai is studying the human heart for his biology project. He comes across the term 'inotropy'. What does it refer to in the context of the heart?

• The amount of blood Kai's heart pumps in one minute

• The strength or force of Kai's heart contractions

• The electrical activity of Kai's heart

• The percentage of blood ejected from Kai's left ventricle with each contraction

Benjamin is experiencing chest discomfort during his morning run. He has a prescription for NTG (nitroglycerine) sublingual. Why might his doctor have prescribed this medication?

• To relieve chest pain and increase blood flow to the heart

• To lower blood pressure

• To treat bacterial infections

• To reduce blood clot formation

Evelyn, Jackson, and Nora are studying for their biology exam. They are learning about the human heart and its sounds. Evelyn asks, 'What is the first heart sound we hear during a heartbeat?'

• S1/LUB

• S2/DUB

• S3

• S4
