In determining blood pressure by auscultatory method_____________?
Correct answer: C. The first sound heard is the systolic pressure
- A. The loudest sound is the diastolic pressure
- B. Systolic pressure estimation tends to be lower than those make by palpatory method
- C. The first sound heard is the systolic pressure
- D. The sounds that are heard are generated in heart
Explanation
In the auscultatory method, the first Korotkoff sound appears when cuff pressure falls just below systolic pressure. The sounds are produced by turbulent blood flow in the compressed artery, not directly by the heart.
