Question

Quizplus · Accepted Answer

A buffer is a substance or mixture of substances that prevents significant changes in pH by reacting with any added acid or base.

Answer: B
 pH (potential hydrogen) is a measure of the acidity or basicity of a solution based on the concentration of hydrogen ions present.

Answer: C
 A buffer is a substance or mixture of substances that prevents significant changes in pH by reacting with any added acid or base.

Answer: D
 An acid is a substance that donates hydrogen ions (H+) to a solution, thereby increasing its acidity.

Answer: E
 Alkalosis refers to a state in which the pH of the blood is higher than normal (above 7.45), usually due to excess alkaline substances or a reduction in carbon dioxide levels.

Answer: F
 Chloride shift refers to the movement of chloride ions (Cl-) from the plasma to red blood cells in exchange for bicarbonate ions (HCO3-), which helps maintain the pH balance of blood.

Answer: G
 Acidosis refers to a state in which the pH of the blood is lower than normal (below 7.35), usually due to an excess of acid or a decrease in alkaline substances.

Answer: H
 Metabolic alkalosis is a state in which the pH of the blood is higher than normal (above 7.45) due to an excess of bicarbonate ions or a decrease in acid.

Answer: I
 Metabolic acidosis is a state in which the pH of the blood is lower than normal (below 7.35) due to an excess of acid or a decrease in bicarbonate ions.

Answer: J
 Respiratory acidosis is a state in which the pH of the blood is lower than normal (below 7.35) due to an accumulation of carbon dioxide in the blood, usually caused by impaired lung function.

Answer: K
 Respiratory alkalosis is a state in which the pH of the blood is higher than normal (above 7.45) due to a reduction in carbon dioxide in the blood, usually caused by hyperventilation.
