Which of the following terms best describes a decrease in blood pressure?

Hypotension is the term that specifically refers to a decrease in blood pressure. It is used in medical terminology to describe any blood pressure reading that is lower than the normal range, often defined as below 90/60 mmHg. This condition can lead to symptoms such as dizziness, fainting, and in severe cases, shock.

Hypertension, on the other hand, denotes elevated blood pressure, often characterized by readings over 130/80 mmHg, which is the opposite of hypotension. Normotension indicates normal blood pressure, signifying that it lies within the healthy range, while crisis typically denotes an emergency situation or a sudden and severe health event, often associated with hypertensive crises or other acute medical emergencies. Therefore, hypotension is the most appropriate term for a decrease in blood pressure.
