# Pulse Pressure

ACTMAT-A4FEEK

Doctors measure pulse pressure as systolic blood pressure (SBP) minus the diastolic blood pressure (DBP).

The pulse pressure is said to be narrow (abnormal) if it is less than 25% of SBP.

If SBP drops to 90 mm Hg, what is the maximum value of DBP at which the pulse pressure will still be in the normal range (in other words, above abnormal)?

A

$\text{75 mm Hg}$

B

$\text{67.5 mm Hg}$

C

$\text{60 mm Hg}$

D

$\text{50 mm Hg}$

E

$\text{45 mm Hg}$
