Practical BP & CVS Adaptation

What is the first sound heard during the auscultation method of blood pressure measurement?

• • Diastolic BP

• • Korotkoff sound Phase 2

• • Systolic BP

• • Pulse pressure

Which of the following statements is correct regarding mean arterial pressure (MAP)?

• • MAP = DBP + 2/3 (SBP – DBP)

• • MAP = SBP - DBP

• • MAP = SBP + 1/3 (SBP – DBP)

• • MAP = DBP + 1/3 (SBP – DBP)

What happens to heart rate and blood pressure immediately after prolonged standing?

• • Both decrease immediately.

• • Heart rate decreases while blood pressure increases.

• • Heart rate increases while blood pressure decreases slightly.

• • Both remain unchanged.

Which of the following best explains the effect of isotonic exercise on diastolic blood pressure?

• • It increases significantly.

• • It decreases or remains the same.

• • It increases more than systolic BP.

• • It remains constant regardless of exercise intensity.

Which of the following best describes isometric exercise?

• • Muscle contraction with movement, like cycling.

• • Muscle contraction without significant movement, like gripping a dynamometer.

• • Relaxation after exercise.

• • Alternating periods of high and low resistance.
