A patient with a viral illness and severe vomiting has an elevated CO2 level and pH of 7.53. She is
breathing slowly. What condition does she have? - ANSWER-Metabolic alkalosis
The patient's pH and CO2 levels are both elevated (moving in the same direction). This indicates
metabolic alkalosis. The CO2 level is high because her respiratory system is attempting to
compensate for the high pH by exhaling less and retaining more CO2.
,Normal CO2 level - ANSWER-35-45
Normal pH level - ANSWER-7.35-7.45
Normal HCO3 level - ANSWER-22-26
Michael's pulmonary edema leads to respiratory acidosis. How does pH impact Michael's basal
metabolic panel? Choose 3 answers.
His CO2 level is increased because his lungs have difficulty removing it from the bloodstream.
His calcium level is reduced because the elevated concentration of H+ makes it easier for Ca+ to bind
to albumin.
His CO2 level is decreased because his lungs have difficulty adding it into the bloodstream.
His sodium level is decreased due to hypervolemia.
His K+ is elevated because, as H+ moves inside of cells in an attempt to get it out of the bloodstream,
K+ moves from cells into the bloodstream. - ANSWER-His CO2 level is increased because his lungs
have difficulty removing it from the bloodstream.
His sodium level is decreased due to hypervolemia.
His K+ is elevated because, as H+ moves inside of cells in an attempt to get it out of the bloodstream,
