Nanoparticles

a. are engineered structures that are less than 100 nm in size

b. have no chemical properties

c. are blocked from the central nervous system

d. are easily measured in biologic tissues

a. Nanoparticles are engineered structures that are less than 100 nm in size.

Toxicity

a. affects all ages to the same degree

b. is independent of racial and genetic background

c. has no important genetic factors

d. is affected by atmospheric pressure, temperature, and humidity

d. Toxicity is affected by atmospheric pressure, temperature, and humidity.

G6PD deficiency

a. primarily affects white males and persons of Mediterranean descent

b. is an X-linked recessive disorder

c. prevents hemolysis from many drugs

d. screening is supported by solid evidence

b. G6PD deficiency is an X-linked recessive disorder.

Biotransformation

a. occurs in the liver by hydrolysis, oxidation, reduction, and conjugation

b. is independent of microsomal cytochrome P450

c. can be arrested by many environmental and pharmacologic agents

d. is accelerated in neonates

a. Biotransformation occurs in the liver by hydrolysis, oxidation, reduction, and conjugation.

Clearance

a. is the rate at which a toxic agent is excreted, multiplied by the average concentration of the agent in the plasma

b. is a function of concentration in the urine, unrelated to dose

c. is a measure of how many milligrams of toxin is being removed

d. is a measure of the volume of fluid that is freed of the toxic agent per unit of time

d. Clearance is a measure not of how many milligrams of toxin is being removed but rather of the volume of fluid that is freed of the toxic agent per unit of time.
