#1
Which of the following is a major risk factor for cardiovascular disease?
High blood pressure
ExplanationHigh blood pressure increases the workload on the heart and can damage arteries over time.
#2
What dietary component is known to contribute to high cholesterol levels?
Saturated fats
ExplanationSaturated fats raise LDL cholesterol levels, increasing the risk of cardiovascular disease.
#3
What is the medical term for high blood pressure?
Hypertension
ExplanationHypertension refers to consistently elevated blood pressure levels, a significant risk factor for cardiovascular disease.
#4
Which type of exercise is particularly beneficial for cardiovascular health?
High-intensity interval training (HIIT)
ExplanationHIIT improves cardiovascular fitness efficiently by alternating short bursts of intense exercise with brief recovery periods.
#5
Which vitamin is essential for the synthesis of collagen, a protein that supports blood vessel integrity?
Vitamin C
ExplanationVitamin C is necessary for the production of collagen, which helps maintain the structural integrity of blood vessels.
#6
Which of the following is NOT a symptom of a heart attack?
Sudden loss of consciousness
ExplanationWhile heart attack symptoms may include chest pain, shortness of breath, and nausea, sudden loss of consciousness is not typically associated with a heart attack.
#7
Which lifestyle factor is associated with a decreased risk of cardiovascular disease?
Healthy diet
ExplanationA healthy diet rich in fruits, vegetables, and whole grains can lower the risk of cardiovascular disease.
#8
What is the term used to describe the buildup of plaque in the arteries?
Atherosclerosis
ExplanationAtherosclerosis is the gradual buildup of plaque in the arteries, narrowing them and restricting blood flow.
#9
What is the recommended maximum daily intake of sodium for adults?
1500 milligrams
ExplanationLimiting sodium intake to 1500 milligrams per day helps reduce the risk of hypertension and cardiovascular disease.
#10
Which of the following conditions is closely linked to an increased risk of cardiovascular disease?
Rheumatoid arthritis
ExplanationRheumatoid arthritis is associated with systemic inflammation, which can contribute to cardiovascular disease.
#11
What is the term used to describe the proportion of blood that is ejected from the heart during each contraction?
Ejection fraction
ExplanationEjection fraction measures the percentage of blood pumped out of the heart's chambers with each contraction, indicating heart function.
#12
Which of the following is a primary function of HDL cholesterol?
Transporting cholesterol to the liver for excretion
ExplanationHDL cholesterol removes excess cholesterol from the bloodstream and transports it to the liver for elimination, reducing the risk of plaque buildup in arteries.
#13
Which of the following factors is NOT typically considered a risk factor for cardiovascular disease?
High HDL cholesterol
ExplanationHigh levels of HDL cholesterol are generally protective against cardiovascular disease.
#14
What is the term used to describe the sudden blocking of a blood vessel by a blood clot?
Embolism
ExplanationAn embolism occurs when a blood clot travels through the bloodstream and blocks a blood vessel, potentially causing serious complications.
#15
What is the term used to describe the cessation of electrical activity in the heart, leading to cardiac arrest?
Asystole
ExplanationAsystole is the absence of electrical activity in the heart, resulting in a lack of blood flow and cardiac arrest.
#16
What is the term used to describe a sudden, severe headache often accompanied by other symptoms such as confusion, trouble speaking, or weakness in the arms or legs?
Stroke
ExplanationA stroke occurs when blood flow to the brain is interrupted, leading to neurological symptoms such as sudden severe headache, confusion, and weakness.
#17
Which of the following is a non-modifiable risk factor for cardiovascular disease?
Age
ExplanationAge is a non-modifiable risk factor for cardiovascular disease, as the risk increases with advancing age due to factors like arterial stiffness and cumulative damage.
