ANSWER 1) Metabolic acid is a condition of increased acid formation in the blood and inability to generate sufficient bicarbonate. This happens when kidneys are not functioning adequately to remove this excess of acid and results in acidemia. The blood pH is low i.e less that 7.35. Extreme acidemia leads to neurolgical and cardiac symptoms and thereby leads to lethargy and weakness. The loss of bicarbonate can occur through gastrointestinal tract vis diarrhea which can also contribute to the symptoms of lethargy and weakness.
ANSWER 2: The normal carbondioxide in the blood when analyzed through arterial blood gas analysis is 35-45 mmHg. But in case of metabolic acidosis, the carbondioxide value ranges according to the compensatory mechanism. During uncompensatory metabolic acidosis, the carbondioxide remains normal but in both partiall and fully compensated, the carbondioxide is decreased i.e less than 35 mmHg. Example : the PCO2 will be 30 mmHg.
ANSWER: 3) The body fluid whether intracellular or extracellular carries various elctrolytes and ions and cations. Thus maintainance of body fluids is important for hemostasis and maintaing blood pH. Water is lost from the body through urine, stool, sweat, insensible water loss. The blood pH tends to decrease when the loss of bicarbonate ions occurs as a result of this vomiting or diarrhea. This in turn increases the H+ ion in the blood and acidosis occurs which is manifested by decreased blood pH.
ANSWER 4) When blood pH is low its called acidosis. It may be metabolic or respiratory acidosis.
