1. Measurement of Blood Pressure Accurately

Steps for Accurate Blood Pressure Measurement 1. Prepare the Patient o Ensure the patient is relaxed and seated comfortably for at least 5 minutes. o Avoid caffeine, smoking, or exercise for at least 30 minutes before measurement. o Have the patient empty their bladder before the reading. 2. Position the Patient Properly o Sit the patient in a chair with back support, feet flat on the floor, and legs uncrossed. o Support the arm at heart level using a table or armrest. o Keep the upper arm exposed (remove tight clothing or roll up the sleeve without constricting the arm). 3. Select the Appropriate Cuff Size o Use a cuff that covers 80% of the upper arm circumference and is 40% of the arm width. o A cuff that is too small will overestimate BP, while a cuff that is too large will underestimate BP. 4. Place the Cuff Correctly o Wrap the cuff snugly around the upper arm, about 2-3 cm above the elbow crease. o Ensure the artery marker on the cuff aligns with the brachial artery. 5. Ensure Proper Inflation & Deflation o Palpate the brachial artery and inflate the cuff 20-30 mmHg above the expected systolic BP. o Deflate the cuff slowly at 2-3 mmHg per second while listening with a stethoscope. 6. Record the Blood Pressure Readings o Identify the first Korotkoff sound (systolic BP) and the disappearance of the sound (diastolic BP). o Take at least two readings spaced 1-2 minutes apart and average them. o If there’s a ≥5 mmHg difference, take additional readings. 7. Follow Best Practices o Measure BP in both arms initially; if there is a difference, use the arm with the higher reading. o Avoid talking or moving during the measurement. o For home monitoring, check BP at the same time daily

USMLE-Style MCQs on Blood Pressure Measurement 1. A 55-year-old man with hypertension presents for a follow-up visit. You plan to measure his blood pressure. Which of the following is the most appropriate patient preparation before obtaining an accurate reading? A) Have the patient stand for 5 minutes before the measurement B) Ensure the patient has exercised 15 minutes prior to the reading C) Allow the patient to rest quietly for at least 5 minutes in a seated position D) Instruct the patient to keep their legs crossed and arm unsupported E) Encourage the patient to talk while the blood pressure is being measured Answer: C) Allow the patient to rest quietly for at least 5 minutes in a seated position 2. A 62-year-old woman presents for routine evaluation. Blood pressure measurement shows a significant difference between readings in both arms. Which of the following is the best next step? A) Repeat blood pressure measurement in both arms B) Use the lower blood pressure reading for diagnosis C) Immediately start antihypertensive medication D) Measure blood pressure in the legs instead E) Perform an echocardiogram to rule out heart failure Answer: A) Repeat blood pressure measurement in both arms 3. A 48-year-old man with no prior history of hypertension presents for an annual check-up. His initial blood pressure reading is 150/95 mmHg. What is the most appropriate approach to confirm the diagnosis of hypertension? A) Start antihypertensive therapy immediately B) Measure blood pressure on two or more separate occasions C) Perform a single 24-hour ambulatory blood pressure monitoring D) Check only diastolic blood pressure for future readings E) Repeat the measurement immediately after the first reading Answer: B) Measure blood pressure on two or more separate occasions 4. A 35-year-old man presents for a wellness visit. He is seated with his back unsupported, legs crossed, and his arm hanging down while his blood pressure is measured. How might these factors affect the reading? A) The reading will be falsely low B) The reading will be falsely high C) There will be no significant effect on the reading D) The systolic pressure will be low, but diastolic pressure will be high E) The diastolic pressure will be low, but systolic pressure will be high Answer: B) The reading will be falsely high 5. A 67-year-old man with diabetes and chronic kidney disease presents for a follow-up visit. His blood pressure is measured using an automatic cuff over a long-sleeved shirt. How might this impact the reading? A) The reading will be falsely low B) The reading will be falsely high C) The reading will be unaffected D) The diastolic pressure will be more accurate than the systolic pressure E) The systolic pressure will be falsely low, while the diastolic pressure remains unchanged Answer: B) The reading will be falsely high
