#1
Which of the following is a risk factor for cardiovascular disease?
Smoking
ExplanationSmoking increases the risk of cardiovascular diseases by damaging blood vessels and increasing clot formation.
#2
What is the medical term for high blood pressure?
Hypertension
ExplanationHypertension refers to high blood pressure, which can lead to various cardiovascular complications.
#3
Which of the following is a common symptom of coronary artery disease?
Chest pain or discomfort
ExplanationChest pain or discomfort is a common symptom of coronary artery disease, indicating reduced blood flow to the heart muscle.
#4
Which of the following is a diagnostic test used to evaluate cardiovascular health?
Electrocardiogram (ECG)
ExplanationAn electrocardiogram (ECG) is a diagnostic test that records the electrical activity of the heart to assess its function and identify abnormalities.
#5
Which of the following is a symptom of congestive heart failure?
Persistent coughing
ExplanationPersistent coughing is a symptom of congestive heart failure, often due to fluid buildup in the lungs.
#6
Which of the following is a symptom of anemia?
Pale skin
ExplanationAnemia can cause pale skin due to reduced oxygen-carrying capacity in the blood.
#7
What is the primary function of red blood cells?
Carrying oxygen to body tissues
ExplanationRed blood cells transport oxygen from the lungs to body tissues and organs.
#8
What is the main function of platelets in the blood?
Forming blood clots
ExplanationPlatelets play a crucial role in blood clot formation to prevent excessive bleeding.
#9
Which of the following is a type of white blood cell responsible for engulfing pathogens?
Neutrophil
ExplanationNeutrophils are a type of white blood cells that play a key role in the immune system by engulfing and destroying pathogens.
#10
What is the most common type of anemia worldwide?
Iron-deficiency anemia
ExplanationIron-deficiency anemia is the most common form of anemia globally, often due to inadequate iron intake or absorption.
#11
What is the term for the process of blood cell formation?
Hematopoiesis
ExplanationHematopoiesis is the process of blood cell formation, occurring primarily in the bone marrow.
#12
Which condition is characterized by irregular heartbeats?
Arrhythmia
ExplanationArrhythmia refers to abnormal heart rhythms, which can lead to various cardiac issues.
#13
Which of the following is a risk factor for developing deep vein thrombosis (DVT)?
Prolonged immobility
ExplanationProlonged immobility increases the risk of DVT by slowing blood flow and promoting clot formation in deep veins.
#14
What is the medical term for the condition characterized by an inadequate supply of oxygen to tissues and organs?
Hypoxemia
ExplanationHypoxemia refers to low oxygen levels in the blood, which can lead to tissue and organ damage.
#15
Which of the following is a common cause of anemia in developing countries?
Parasitic infections
ExplanationParasitic infections, such as malaria and hookworm, are common causes of anemia in developing nations by causing blood loss and impairing iron absorption.
#16
Which of the following is a risk factor for developing atherosclerosis?
High blood pressure
ExplanationHigh blood pressure contributes to the development of atherosclerosis by damaging arterial walls and promoting plaque formation.
#17
Which of the following is a risk factor for peripheral artery disease (PAD)?
High blood pressure
ExplanationHigh blood pressure is a risk factor for peripheral artery disease (PAD), contributing to arterial damage and narrowing, reducing blood flow to extremities.
