MLS CHEMISTRY FINAL EXAM QUESTIONS
AND ANSWERS WITH VERIFIED
SOLUTIONS 100% CORRECT
ABG Air exposure - correct answer- Increased pH
increased pO2, if sample <150mmhg
decreased pO2, if sample >150mmhg
decreased PCO2
ABG collection criteria - correct answer-
heparinized syringe
on ice and receive in one hour of draw
no air bubbles and with cap
labeled correctly
ABG Without ice - correct answer- decreased pH
decreased pO2
increased pCo2
, Acid Phosphatase - correct answer- - indicator of
prostate cancer (increased)
ALP - correct answer- - cofactors zinc and
magnesium
- increased in bone/liver disease, pregnancies, malignancy
- decreased in hypophosphatasia, hypothyroidism, starvation.
protein deficiencies
ALT - correct answer- - increased in liver diseases
(elevated than AST)
- Elevation persists longer than AST, used to diagnose chronic
hepatitis
AMY - correct answer- - requires Ca cofactor
- increased in acute pancreatitis (increased in urine) and biliary
obstruction (increased in serum)
Anion Gap (AG) - correct answer- Na - (Cl + HCO3)
Anti-asthmatic/ bronchodilator - correct answer-
Theophylline
