RNSG 1128 Exam # 3 Questions With
Verified Answers
pH Regulators Of The Body - answer✔-bicarbonate
-phosphate
-protein
-hemoglobin
Acid - Base Roles H+ Compounding - answer✔-acid: release H+
-base: accept H+
Acid - Base Balance: Hypoalbuminemia - answer✔-proteins are the largest buffer system in the
body.
-amphoteric: Can function as acid or base.
-albumin: Major protein buffers in vascular compartment.
Anion Gap - answer✔-cation (Na+) - Anions (Cl- & HCO3) = concentration of unmeasured
anions.
-ketoacidosis: Increased anion gap which results in decreased HCO3.
Carbon Dioxide Transport: Plasma - answer✔-(10%) CO2 is transported in the dissolved state to
the lungs and exhaled.
Carbon Dioxide Trasport: Bicarbonate - answer✔-70% CO2 > RBC's (carbonic anhydrase
catalyzes CO2 + H2O - H2CO3 or carbonic acid) > H2CO3 - H+ = HCO3 or bicarbonate > diffuses
into plasma to participate in acid - base regulation.
Carbon Dioxide Transport: Hemoglobin - answer✔-20% CO2 + Hemoglobin within the RBC =
carbaminohemoglobin (HbCO2); loose bond allows CO2 to be released in aveolar capillaries >
exhaled from the lung.
