NR 565 Week 1 Quiz
Question 1
pts
Which of the following pharmacokinetic factors exhibits racial differences?
Absorption.
Passive tubular reabsorption.
Filtration at the glomrulus.
Protein binding.
The pharmacokinetic factors that can be expected to potentially exhibit racial
differences are (1) bioavailability for drugs that undergo gut or hepatic first-pass
metabolism, (2) protein binding, (3) volume of distribution, (4) hepatic metabolism, and
(5) renal tubular secretion. Absorption, filtration at the glomerulus, and passive tubular
reabsorption would not be expected to exhibit such differences.
Question 2
pts
Rifampin is a nonspecific CYP450 inducer that may ?
Cause nonspecific changes in drug metabolism.
Lead to toxic levels of rifampin (Rifadin) and must be monitored closely.
Induce the metabolism of drugs, such as oral contraceptives, leading to therapeutic
failure.

, Cause toxic levels of drugs, such as oral contraceptives, when coadministered.
it takes less than 2 days for rifampin, which is a nonspecific CYP450 inducer with a
shorter half-life, to decrease blood concentrations of many drugs to a subtherapeutic
level and significantly increase the risk of therapeutic failure.
Question 3
pts
Which of the following is an excitatory amino acid (aka excitatory neurotransmitter)?
Insulin.
Gama-aminobutyric acid.
Acetylcholine.
Glutamate.
Glutamate is an excitatory NT
Question 4
pts
Which statement describes one way in which drugs interact with G-protein-coupled
receptors?
Drugs enter through G-protein-coupled receptors and stimulate the receptor to release
various effector proteins to produce physiological responses via third messengers.
