CARE 2 EXAM
When acid base is balanced it is characterized by? - ANSWER-fluid containing
equal number of positive charges, ions with negative
charges
Changes in acid base balance can affect - ANSWER--shape of hormones and
enzymes
-distribution of other electrolytes
-excitable membranes
-effectiveness of hormones and drugs
ABG (Arterial Blood Gas) measures - ANSWER-the acidity (pH) and the levels of
oxygen and carbon dioxide in the blood from an artery
what are 3 parts to an ABG - ANSWER--pH 7.35-7.45
-Co2 35-45 (this is an acid) (higher the number more acidic)
-Hco3 22-26 (bicarb)
Respiratory issue= - ANSWER-renal system compensates Metabolic issue= -
ANSWER-lungs compensate
if pH and Co2 same side= - ANSWER-respiratory issue if pH and HCo3 same
side= - ANSWER-metabolic issue Compensated means - ANSWER-the pH is
normal
