Questions And Answers
The nurse is administering parenteral drugs. Which statement is true regarding parenteral drugs?
A. Parenteral drugs bypass the first-pass effect.
B. Absorption of parenteral drugs is affected by reduced blood flow to the stomach.
C. Absorption of parenteral drugs is faster when the stomach is empty.
D. Parenteral drugs exert their effects while circulating in the bloodstream. A. Parenteral
drugs bypass the first-pass effect.
Rationale: Drugs given by the parenteral route bypass the first-pass effect. Reduced blood flow
to the stomach and the presence of food in the stomach apply to enteral drugs (taken orally), not
to parenteral drugs. Parenteral drugs must be absorbed into cells and tissues from the circulation
before they can exert their effects: they do not exert their effects while circulating in the
bloodstream.

stage renal disease. The nurse is aware that patients with kidney failure would most likely have
problems with which pharmacokinetic phase?

Questions And Answers
A. Excretion
B. Absorption
C. Metabolism
D. Distribution A. Excretion
Rationale: The kidneys are the organs that are most responsible for drug excretion. Renal
function does not affect the absorption and distribution of a drug. Renal function may affect
metabolism of drugs to a small extent.
