Question 1 of 5
Why should a palpated pressure be performed before auscultating blood pressure?
Correct Answer: B
Rationale: Performing a palpated pressure before auscultating blood pressure helps in detecting the presence of an auscultatory gap. An auscultatory gap is a period during blood pressure measurement when Korotkoff sounds temporarily disappear before reappearing. Inflation of the cuff 20 to 30 mm Hg beyond the point where a palpated pulse disappears helps in identifying this gap. This technique ensures accurate blood pressure measurement by preventing the underestimation of blood pressure values. The other options are incorrect because palpating the pressure is not primarily done to hear Korotkoff sounds more clearly, avoid missing falsely elevated blood pressure, or readily identify a specific phase of Korotkoff sounds.
