Question

A nurse measures the blood pressure of a seated patient to be $190$ mm of Hg.

• A. the blood pressure at the patient's feet is less than $190$ mm of Hg.
• B. the actual pressure is about $0.25$ times the atmospheric pressure.
• C. the blood pressure at the patient's neck is more than $190$ mm of Hg.
• D. the actual pressure is about $1.25$ times the atmospheric pressure.

Answer 1

The correct option is D the actual pressure is about $1.25$ times the atmospheric pressure.

$P_{exp}=P_0+P_{Actual}190=76+P_{Actual}{P}_{Actual}=114mmofHgFactor=\frac{P_{Actual}}{P_{atm}}=\frac{114}{76}\approx 1.25$
