Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
c. Respiratory compensation for metabolic acidosis consists of hypoventilation.

검증된 단계별 안내

Step 1: Understand the concept of metabolic acidosis. Metabolic acidosis occurs when there is an excess of acid in the body due to factors such as increased production of hydrogen ions or loss of bicarbonate ions. This leads to a decrease in blood pH.

Step 2: Learn about respiratory compensation. The respiratory system compensates for metabolic acidosis by adjusting the rate and depth of breathing to regulate carbon dioxide (CO₂) levels, which directly affect blood pH.

Step 3: Recall the relationship between CO₂ and pH. CO₂ combines with water in the blood to form carbonic acid (H₂CO₃), which dissociates into hydrogen ions (H⁺) and bicarbonate ions (HCO₃⁻). Increased CO₂ levels lower pH, while decreased CO₂ levels raise pH.

Step 4: Analyze the statement. Hypoventilation (reduced breathing rate) leads to an accumulation of CO₂, which would further decrease pH. This is the opposite of what is needed to compensate for metabolic acidosis. Therefore, hypoventilation is not the correct respiratory response.

Step 5: Correct the statement. The true respiratory compensation for metabolic acidosis is hyperventilation (increased breathing rate), which helps to expel more CO₂ from the body, thereby raising blood pH and counteracting the acidosis.

주요 개념

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

Metabolic Acidosis

Metabolic acidosis is a condition characterized by an excess of acid in the body due to increased production of acid or decreased ability to excrete acid by the kidneys. It can result from various factors, including diabetic ketoacidosis, renal failure, or severe diarrhea. Understanding this condition is crucial for recognizing the body's compensatory mechanisms.

Respiratory Compensation

Respiratory compensation refers to the body's physiological response to changes in blood pH levels. In the case of metabolic acidosis, the body compensates by increasing the rate and depth of breathing (hyperventilation) to expel more carbon dioxide, which helps raise blood pH back to normal. This process is essential for maintaining acid-base balance.

Hypoventilation vs. Hyperventilation

Hypoventilation is a condition where breathing is too shallow or slow, leading to an increase in carbon dioxide levels and a decrease in blood pH. In contrast, hyperventilation involves rapid or deep breathing, which decreases carbon dioxide levels and can help correct acidosis. Understanding the difference between these two terms is vital for accurately assessing respiratory compensation.
