During a routine check-up, a 45-year-old patient gets his blood pressure measured. When positioning the patient's arm, you notice the patient is seated with his legs crossed at the knee. How should you proceed to ensure an accurate blood pressure reading?
Only support the patient's arm at heart level without addressing the crossed legs, and take the blood pressure reading.
You should ask the patient to uncross their legs, place both feet flat on the floor, and support the arm at heart level.
Ask the patient to stand up and take the blood pressure reading while they are in a more natural standing posture.
Proceed with the reading, as the crossed legs do not significantly impact the blood pressure reading.
