incorrect because the medication ordered will not change.
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. - (ANSWER)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.
