Real-Based Questions with Verified Answers|
Guaranteed Perfect Score 100%
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 - 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
anion gap calculations - Correct Answers-Na+ -(Cl- + HCO3-)= 5-14 mmol/L
[Na+ + K+] - [Cl- + HCO3-] = 9-18mmol
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
BCP+ albumin abs - Correct Answers-610nm
blood buffer reference range - Correct Answers-46-49 mEq/L
bone mineralization and reabsorption is regulated by ___ and ____ - Correct Answers-PTH
and calcitonin
BUN is a product of the catabolism of: - Correct Answers-proteins
BUN/Creatinine Ratio - Correct Answers-10:1 to 20:1
CAD - Correct Answers-plaque that builds up in the arteries leading to the heart
calcitonin decreases - Correct Answers-calcium and phosphorus levels
calcitonin has an ____ effect on PTH - Correct Answers-antagonistic
calcitonin inhibits: - Correct Answers-osteoclasts
calcitonin is produced by the C cells of the - Correct Answers-thyroid gland
Calomel reference electrode - Correct Answers-contains a salt bridge
saturated KCl
causes of hypernatremia - Correct Answers-dehydration
diabetes insipidus
polyuria
