A normal resting blood pressure for a young adult is recorded as
Correct answer: B. 120/80 mm Hg
- A. 80/120 mm Hg
- B. 120/80 mm Hg
- C. 200/100 mm Hg
- D. 60/40 mm Hg
Explanation
The larger figure is the systolic pressure during ventricular contraction and the smaller is the diastolic pressure while the ventricles are relaxed and filling, and the systolic value is always written first. A sustained reading at or above about 140/90 is hypertension, which strains the heart and damages arteries, kidneys and the retina. Reversing the two numbers is the classic careless error.

About Blood Vessels
Blood vessels include arteries, arterioles, capillaries, venules and veins, whose wall thickness, elasticity, lumen size and valves suit their roles in circulation. Questions compare pressure and blood flow in each vessel and distinguish pulmonary vessels, which carry blood to and from the lungs, from systemic vessels.
