At which diastolic blood pressure should a personal trainer be concerned about hypertension in a client and refer them to a physician as they may be "pre-hypertensive?"
a. less than 80 mmHg
b. greater than 120 mmHg
c. between 80 and 89 mmHg
d. between 70 and 79 mmHg
e. greater than 90 mmHg
Answer: c. between 80 and 89 mmHg
Between 80 and 89 mmHg is correct because a normal diastolic blood pressure is under 80 mmHg, a pre-hypertensive blood pressure is between 80 and 89 mmHg, and a hypertensive blood pressure is 90 mmHg or greater. Diastolic blood pressure is the pressure within the arterial blood vessels when the heart is resting and filling with blood. It is measured during a blood measure test as the point at which the sound of the pulse fades away through the stethoscope.
