#1
Which of the following is NOT a risk factor for cardiovascular disease?
Regular exercise
ExplanationRegular exercise is a protective factor, reducing the risk of cardiovascular disease.
#2
What does an electrocardiogram (ECG or EKG) measure?
Heart rate
ExplanationECG measures the electrical activity of the heart, not the heart rate directly.
#3
What is the typical resting heart rate for adults?
70-100 beats per minute
ExplanationA normal resting heart rate for adults falls within the range of 70-100 beats per minute.
#4
Which of the following is a common symptom of heart failure?
Shortness of breath
ExplanationShortness of breath is a common symptom of heart failure, indicating compromised heart function.
#5
What is the medical term for a heart attack?
Myocardial infarction
ExplanationMyocardial infarction is the medical term for a heart attack, indicating tissue damage due to inadequate blood supply.
#6
Which of the following is a symptom of a heart attack?
Nausea and vomiting
ExplanationNausea and vomiting are uncommon symptoms of a heart attack; chest pain is more typical.
#7
What is the function of a Holter monitor?
To monitor heart rhythm over 24 to 48 hours
ExplanationA Holter monitor continuously records the heart's electrical activity over an extended period for rhythm analysis.
#8
What does a stress test assess?
Cardiac function under exertion
ExplanationA stress test evaluates the heart's performance during physical exertion, revealing potential issues under stress.
#9
Which of the following is a risk factor for arrhythmia?
High blood pressure
ExplanationHigh blood pressure increases the risk of arrhythmias, irregular heartbeats.
#10
What does a lipid profile test measure?
Cholesterol levels
ExplanationA lipid profile test measures cholesterol levels, including HDL, LDL, and triglycerides, assessing cardiovascular risk.
#11
Which of the following is a method for assessing cardiac function?
Echocardiogram
ExplanationEchocardiogram uses sound waves to create images of the heart's structure and function, assessing cardiac health.
#12
What is the purpose of a cardiac catheterization?
To inject dye into the coronary arteries
ExplanationCardiac catheterization involves injecting dye into coronary arteries to visualize blood flow and detect blockages.
#13
What is the primary purpose of an exercise stress test?
To evaluate heart function during physical exertion
ExplanationAn exercise stress test assesses how the heart responds to physical exertion, helping diagnose heart conditions.
#14
Which imaging technique provides detailed images of the heart's blood vessels?
MRI angiography
ExplanationMRI angiography produces detailed images of the heart's blood vessels, aiding in the diagnosis of vascular issues.
#15
What is the term for a condition characterized by the buildup of fatty deposits in the arteries, restricting blood flow?
Atherosclerosis
ExplanationAtherosclerosis is the condition marked by the accumulation of fatty deposits in arteries, leading to reduced blood flow and potential blockages.
