Question

Which term correctly describes the medical condition in which the pH of blood is less than 7.45, and therefore the blood is more basic than normal?

A) Respiratory alkalosis
B) Alkalosis
C) Respiratory acidosis
D) Acidosis

Answer 1

The term describing the medical condition where blood pH is less than 7.45 and is more alkaline than normal is B) Alkalosis, specifically respiratory alkalosis.

Step-by-step explanation:

The term that correctly describes the medical condition in which the blood pH is less than 7.45 and therefore the blood is more alkaline than normal is B) Alkalosis.

Alkalosis occurs when the blood and other body fluids have too few hydrogen ions (H+), making them overly basic. This condition can arise from various causes, including respiratory issues where carbon dioxide (CO₂) levels become too low. Such cases are referred to specifically as respiratory alkalosis, which can be caused by factors such as lung disease, aspirin overdose, shock, or even anxiety. It is important to note that a normal arterial blood pH is within the narrow range of 7.35 to 7.45.
