NRNP 6566 FINAL EXAM| 425 LATEST QUESTIONS WITH CORRECT & VERIFIED ANSWERS|A GRADE (WALDEN UNIVERSITY) 2024 What is bicarb plus a proton: Carbonic acid-which turns into water vapor and co2 molecules, which is then breathe off When bicarb decreases in the body what increases: Chloride What is the Chem-7?: Na( +)I Cl (-)| BUN | K(+)| HCO2 (-) | Cr | Glucose What is an anion gap?: When the two largest negatives are subtracted from the largest positive are greater than the number 12. [(Na+) + (K+)] - [(HCO3 + Cl-)] Calculated in metabolic acidosis Why will an anion gap increase: If HCO3 is lost -because - conjugate base is not detached to a positive proton any longer-because it is now attached to the lost bicarb How can you predict an anion gap from albumin: An albumin of 4 = 12 Ex an albumin of 2=6 What does a high anion/low anion gap mean: high-acidic low-alkalotic How do you calculate the anion gap: Na - (Cl + HCO3) What is normal anion gap: 12 Normal Anion gap should be: Albumin x 3 What is the difference between acidosis and acidemia: Acidosis- is the process going on ie respiratory acidosis Acidemia is the state of being-ie acidotic or alkalotic What is PH: measure of hydrogen ion concentration 7.40-normal 7.45-alkalotic 7.35-acidotic What is the body's natural buffer: Bicarbonate as protons increase: Ph decreases Because protons are positive Counteracted by increasing bicarbonate pH equation: pH=6.1+log[H3O+/PCO2*0.03 normal bicarbonate levels: 22-26 mEq/L Normal pH of blood: 7.35-7.45
