CHS Blood Pressure Measurement Techniques & Monitoring 3

Question 1

Which cuff size is appropriate for a patient with an arm circumference of 38 cm?

Accepted Answer

Large adult cuff (bladder 16 × 38 cm)

Answer

Small adult cuff (bladder 10 × 24 cm)

Answer

Standard adult cuff (bladder 13 × 30 cm)

Answer

Thigh cuff

Question 2

Pseudohypertension—falsely elevated cuff readings due to arterial stiffness—is most commonly encountered in which patient population?

Accepted Answer

Elderly patients with heavily calcified arteries

Answer

Young trained athletes

Answer

Pregnant women in the third trimester

Answer

Obese patients with large arm circumference

Question 3

The Osler maneuver is performed to identify which condition?

Accepted Answer

Pseudohypertension

Answer

Aortic coarctation

Answer

White coat hypertension

Answer

Masked hypertension

Question 4

What effect does talking during blood pressure measurement have on the reading?

Accepted Answer

Increases blood pressure by approximately 10–15 mmHg

Answer

No clinically significant effect

Answer

Decreases blood pressure by approximately 5 mmHg

Answer

Affects only diastolic pressure, not systolic

Question 5

Which patient population requires blood pressure assessment in both seated and standing positions, and why?

Accepted Answer

Older adults and patients with possible orthostatic hypotension

Answer

Pregnant patients, to detect preeclampsia

Answer

Pediatric patients, for developmental norms

Answer

Athletes, to assess exercise tolerance

Question 6

What is an 'auscultatory gap' during blood pressure measurement?

Accepted Answer

A temporary disappearance of Korotkoff sounds between Phases I and II during cuff deflation

Answer

The numerical difference between systolic and diastolic pressure (pulse pressure)

Answer

The time interval between consecutive heartbeats during measurement

Answer

The required waiting period between successive measurements

Question 7

What technique should be used to determine the minimum cuff inflation pressure before beginning auscultatory blood pressure measurement?

Accepted Answer

Palpate the radial pulse while inflating until the pulse disappears, then add 20–30 mmHg

Answer

Auscultate for Korotkoff sounds from the start of inflation

Answer

Estimate based on the patient's age and body weight

Answer

Inflate to a fixed standard of 200 mmHg for all adult patients
