A pH of 7.8 in the human body typifies a condition referred to as
(a) Acidosis
(b) Alkalosis
(c) Dehydration
(d) Homeostasis

검증된 단계별 안내

Step 1: Understand the normal pH range of human blood, which is typically around 7.35 to 7.45, indicating a slightly alkaline environment.

Step 2: Recognize that a pH value below 7.35 indicates acidosis, a condition where the blood is too acidic.

Step 3: Recognize that a pH value above 7.45 indicates alkalosis, a condition where the blood is too alkaline.

Step 4: Compare the given pH value of 7.8 to the normal range and determine whether it is acidic or alkaline relative to normal blood pH.

Step 5: Conclude that since 7.8 is above the normal range, the condition is alkalosis, which corresponds to option (b).

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

pH Scale and Normal Blood pH

The pH scale measures how acidic or basic a solution is, ranging from 0 to 14, with 7 being neutral. Normal human blood pH is tightly regulated between 7.35 and 7.45. Values above this range indicate a more basic (alkaline) state, while values below indicate acidity.

Alkalosis

Alkalosis is a condition where the blood pH rises above the normal range, typically above 7.45, indicating increased alkalinity. It can result from factors like hyperventilation or excessive loss of acids and affects bodily functions by disrupting enzyme activity and electrolyte balance.

Acidosis

Acidosis occurs when blood pH falls below the normal range (below 7.35), indicating increased acidity. It can be caused by respiratory or metabolic issues and leads to symptoms like fatigue and confusion due to impaired cellular function.
