Which is NOT a variable that can alter blood concentration–time profiles?
Age
Gender
Body weight
Race
Why does the presence of disease alter the disposition and effect of some drugs in
some people?The disease can disrupt the drugs’ absorption, distribution, metabolism, and/or excretion.
A hepatic disease allows for more absorption to the kidneys.
A renal disease disrupts excretion of perspiration.
Thyroid disease affects the blood flow, causing a change in heart rhythm.
The ability of a substance to cause renal toxicity is called
Hepatotoxicity
Nephrotoxicity
Teratogenicity
None of the above
Drug-drug interactions are commonly called
Additive, synergistic, or potentiation
Additive, alchemistic, or potentiation
Additive, atravistic, or potentiation
Additive, albinistic, or potentiation
Some drugs are capable of increasing the concentration of
metabolizing enzymes in the liver. This process is called
Enzyme inhibition
Enzyme displacement
Enzyme induction
Enzyme filtration
Additive effects occur when
Two drugs with similar pharmacological actions result in an effect equal to the sum of the individual effects.
Two drugs with similar pharmacological actions produce greater effects than the sum of individual effects.
One drug with no inherent activity increases the activity of another drug, which produces an effect.
None of the above
An antidote to a particular drug is given to
Block or reduce its anticoagulation effects
Block or increase its toxic effects
Block or reduce its toxic effects
Block or increase its anticoagulation effects
The physical presence of food in the gastrointestinal tract can
alter absorption by
Improving the solubility of increasing bile secretion
Altering gastric emptying
Altering liver blood flow
Altering intestinal motility
All of the above
Which statement is NOT true about metabolism?
High protein diets are associated with accelerated metabolism.
High carbohydrate diets appear to decrease metabolism.
The substitution of fat calories for carbohydrate seems not to affect drug metabolism rates.
Generally, mildly or moderately undernourished adults have slower metabolism of drugs.
Which statement is true about reactions of foods with certain
drugs?
MAO inhibitors may produce severe hypotension and intercranial ischemia.
Certain cruciferous vegetables decrease the metabolism of a few drugs.
A patient ingesting foods containing vitamin K while taking an anticoagulant would not receive the full therapeutic effect from warfarin.
All of the above
