Question 7
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?
Correct 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.
Question 8
Normal CO2 level
Correct Answer
35-45
Question 9
Normal pH level
Correct Answer
7.35-7.45
Question 10

,Question 11
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.

Question 12
A hormone panel was done on a patient with congestive heart failure and fluid volume overload. Which elevated hormone
on the patient's chart is indicative of the body's attempt to reduce the fluid overload?
Antidiuretic hormone (ADH)
Brain natriuretic peptide (BNP)
Aldosterone
Renin
Correct Answer
BNP
BNP is released when fluid volume excess is present.
