MMSC 407 Clinical Chemistry Final Exam Questions With
Complete Solutions
2 different forms of calcium in plasma: Correct Answers
diffusible and nondiffusible
3 forms tCO2 is found in: Correct Answers ionized bicarbonate
(90%)
dissolved CO2
carbamino compound
3 main sources of cholesterol Correct Answers diet
biliary secretion
intestinal mucosal cell secretion
90% of endogenous cholesterol is synthesized in the___ Correct
Answers liver
a 12 hour ___ method is required for total cholesterol specimen
Correct Answers fasting
a decrease in intracellular K=, leads to an___ in K+ in plasma
Correct Answers increase
a decrease of extracellular fluid will cause the: Correct Answers
release of renin
A delta check refers to Correct Answers comparing current test
results with previous one
,A Left shift in Oxyhemoglobin Dissociation Curve Correct
Answers A left shift will increase oxygen's affinity for
hemoglobin.
In a left shift condition (alkalosis, hypothermia, etc.) oxygen
will have a higher affinity for hemoglobin. SaO2 will increase at
a given PaO2, but more of it will stay on the hemoglobin and
ride back through the lungs without being used. This can result
in tissue hypoxia even when there is sufficient oxygen in the
blood.
a phospholipid is a glycerol backbone bound to ___ fatty acids.
Correct Answers 2
about 20% of NPNs are composed of__ Correct Answers amino
acids
Acidosis _____ ionized calcium Correct Answers increases
Addison's disease Correct Answers decrease in aldosterone,
primary adrenocortical deficiency
ADH is made in the ________ and stored in the ________.
Correct Answers hypothalamus: posterior lobe of the pituitary
adipose tissue is a common way the body stores excess Correct
Answers glucose
albumin range Correct Answers 3.5-5 g/dL
aldosterone causes: Correct Answers sodium and water
retention
,Alkalosis __ ionized calcium Correct Answers decreases
amperometric circuit Correct Answers measures current flow
between 2 electrodes
increase in current flow indicates excess silver ions in the
solution and the complete titration of chloride ions
2 silver electrodes, low current
an amino acid is a compound having both a: Correct Answers
carboxyl and amino group
An example of a polysaccharide is Correct Answers glycogen
an increase in unmeasured anions means: Correct Answers an
increased anion gap
an increase of absorbance of light generally means Correct
Answers a decrease in transmittance
an increased NPN (azotemia) can be an indicator of____ Correct
Answers renal disease
Analytical Gap Correct Answers difference between
unmeasured anions and unmeasured cations
anion gap calculations Correct Answers Na+ -(Cl- + HCO3-)=
5-14 mmol/L
[Na+ + K+] - [Cl- + HCO3-] = 9-18mmol
, Anion Gap Correct Answers difference between the serum
sodium concentration and the sum of the serum chloride and
bicarbonate concentrations
anion gap is is high in some forms of metabolic acidosis
apolipoprotein A's function is to activate the ____ Correct
Answers LCAT enzyme
Apolipoprotein B Correct Answers a major protein of all
lipoproteins EXCEPT for HDL
Apolipoprotein B-100 Correct Answers helps transport and
clear LDL and VLDL from plasma
Apolipoprotein B-48 Correct Answers mediates chylomicron
secretion
Apolipoprotein function Correct Answers maintain structural
integrity
activate or inhibit enzymes
interact w/ various tissue receptors
Apolipoproteins Correct Answers the protein components of
lipoproteins
atherosclerosis Correct Answers deposition of fatty streaks,
plaque
made up of cholesterol and cholesterol esters
BCG+albumin absorbance Correct Answers 546nm
