Verified
A systolic blood pressure (BP) less than 90 mm Hg or a diastolic BP less than 60 mm Hg is known as:
A) hypertension.
B) hypotension.
C) orthostatic hypotension.
D) postural hypotension.
Orthostatic Hypotension
A form of low blood pressure that happens when standing up from sitting or lying down, causing dizziness or fainting.
Hypotension
A medical condition characterized by abnormally low blood pressure, which can lead to symptoms such as dizziness, fainting, and, in severe cases, shock.
Systolic Blood Pressure
The pressure in the arteries when the heart beats and fills them with blood, the higher of the two blood pressure readings.

Final Answer :
B
Explanation :
Hypotension is a systolic blood pressure (SBP)less than 90 mm Hg or a diastolic blood pressure (DBP)less than 60 mm Hg.The most common alteration in blood pressure is hypertension,an often asymptomatic disorder characterized by persistently elevated blood pressure.Hypertension is defined as SBP greater than 140 mm Hg,DBP greater than 90 mm Hg.Orthostatic hypotension,also referred to as postural hypotension,is a reduction of SBP of at least 20 mm Hg or reduction of DBP of at least 10 mm Hg within 3 minutes of quiet standing.It occurs when patients with normal blood pressure experience a drop in blood pressure upon rising to an upright position and is associated with symptoms of lightheadedness or dizziness.
