CC EXAMS Flashcards
The measurement of voltage between two electrodes in a solution forms the basis for a variety of procedures for measuring analyte concentration:
Potentiometry
It is based on fragmentation and ionization of molecules using a suitable source of energy:
Mass spectrometry
Generally it is used to detect gamma radiation:*
Crystal scintillation counter
A technique for determining the structure of organic compounds; it is nondestructive, although it does require a larger sample volume:
Nuclear magnetic resonanance
Low anion gaps:
Hypoalbuminemia, hypercalcemia and multiple myeloma
The main waste product of nitrogen-containing chemicals in the body:
Urea
The combination of a weak acid or weak base and its salt, is a system that resists changes in pH:
Buffer
The role of the lungs and kidneys in maintaining pH is depicted with the Henderson-Hasselbalch equation. The numerator denotes:
Kidney function
The role of the lungs and kidneys in maintaining pH is depicted with the Henderson-Hasselbalch equation. The denominator denotes:
Lung function
The fifth most common element and is the most prevalent cation in the human body:
Calcium
The fourth most abundant cation in the body and the second most prevalent intracellular cation:
Magnesium
An abnormal lipoprotein found in patients with obstructive biliary disease and in patients with familial lecithin/cholesterol acyltransferase (LCAT) deficiency:
LpX lipoprotein
Lipoprotein(s) have a density of less than 1.006 kg/L (density measurement):
Chylomicrons and VLDL
A striking elevation of transferrin in the β-region sometimes occurs in patients suffering from:
Iron deficiency anemia: A striking elevation of transferrin in the β-region sometimes occurs in patients suffering from iron deficiency anemia. The increase in transferrin corresponds to increased IBC, and the percent saturation is low.
Enzymes _____ the activation energies of the chemical reactions that they catalyze, so as to cause greatly enhanced rates of reaction.
Lower
Different forms of enzymes that catalyze the same reaction:
Isoenzymes
This probably represents alcohol dehydrogenase:
LD6
Stated as E + S = ES = E + P*
Catalytic mechanism
Panic reactions—a bad trip—are the most common adverse reactions.
Lysergic acid diethylamide
The drug of choice for absence (petit mal) seizures unaccompanied by other types of seizures:
Ethosuximide (Zarontin)
Anti-asthmatic drugs:
Theophylline and theobromine: Anti-asthmatic drugs, such as theophylline and theobromine, are used for treatment of neonatal breathing disorders or of respiratory conditions that affect adults or children, such as asthma.
An indication of error in the analysis, detected by a progressive drift of control values in one direction for at least 5 consecutive runs:
Trend
The most common drug of abuse and is frequently responsible for the presentation of patients with altered mental status to hospitals and emergency rooms:
Ethanol
Centrifuge used when rapid centrifugation of solutions containing small particles is needed:
Fixed-angle centrifuge
