A patient has a blood pressure of 155/95 mm Hg. The nurse understands that this patient's risk of cardiovascular disease is _____ greater than normal
a. two times
b. three times
c. four times
d. six times
ANS: C
Cardiovascular disease (CVD) risk doubles with each increase of 20/10 mm Hg above normal, starting at 115/75 mm Hg. This patient's blood pressure is 40/20 above normal, which increases the risk four times. A blood pressure of 135/85 would be two times greater. The patient's risk would still be four times greater with a blood pressure of 155/70 or 130/95, since systolic and diastolic blood hypertension are each powerful predictors of CVD.
