Questions for Cardiovascular Assessment Questions
Question 1 of 5
Which part of the RS complex represents the repolarization of the atria?
Correct Answer: D
Rationale: The QRS complex (RS in this context) represents ventricular depolarization, not atrial repolarization. Atrial repolarization occurs during the QRS but is masked by the larger ventricular signal, so none of the components directly represent it.
Question 2 of 5
A Level Regular aerobic exercise results in significant benefits to the heart and vascular system. What are these benefits and how do they contribute to a 'healthier lifestyle'?
Correct Answer: D
Rationale: Exercise enhances cardiovascular health, reducing risks of diseases and improving overall well-being.
Question 3 of 5
Rough part of left and right atrium derived from?
Correct Answer: A
Rationale: The rough parts of both atria (pectinate muscles) derive from the common primordial atrium in embryonic development.
Question 4 of 5
Which of the following decreases the risk of ventricular fibrillation?
Correct Answer: B
Rationale: An increased refractory period prevents re-entry circuits, reducing the risk of ventricular fibrillation.
Question 5 of 5
Which of the following statements likely condition in someone with atrial fibrillation?
Correct Answer: C
Rationale: Atrial fibrillation causes an irregular and often rapid ventricular rate due to erratic atrial impulses.
