Cardiovascular Assessment Questions Questions
Question 1 of 5
Vasomotor control mechanisms influence:
Correct Answer: D
Rationale: Vasomotor control, regulated by the autonomic nervous system, primarily affects the diameter of arterioles, altering peripheral resistance and blood flow.
Question 2 of 5
Explain what is meant by the term 'cardiovascular drift'.
Correct Answer: D
Rationale: Cardiovascular drift involves physiological changes maintaining cardiac output during prolonged exercise.
Question 3 of 5
Umbilical vein which drains into the sinus venosus originate from?

Rationale: The umbilical vein carries oxygenated blood from the placenta to the fetus, draining into the sinus venosus.
Question 4 of 5
Which of the following is most characteristic of atrial fibrillation?
Correct Answer: C
Rationale: Atrial fibrillation reduces ventricular filling efficiency by 20-30% due to irregular atrial activity.
Question 5 of 5
In the figure above, when does the 3rd heart sound occur?
Correct Answer: D
Rationale: The 3rd heart sound (S3) occurs in early diastole (between C and D) due to rapid ventricular filling.
