A nurse measures the blood pressure of a seated patient to be 190 ~mm of Hg -

Options

  1. AThe blood pressure at the patient's feet is less than 190 ~mm of Hg
  2. BThe actual pressure is about 0.25 times the atmospheric pressure
  3. CThe blood pressure at the patient's neck is more than 190 ~mm of Hg
  4. DThe actual pressure is about 1.25 times the atmospheric pressure

Correct answer

D. The actual pressure is about 1.25 times the atmospheric pressure

Step-by-step solution

Blood pressure is gauge pressure =190 ~mm Hg Atmospheric pressure =760 ~mm Hg Actual pressure =190+760 ~mm Hg =950 ~mm Hg =1.25 760 ~mm Hg
