, ECPI NUR 138
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.

from end-stage renal disease. The nurse is aware that patients with kidney failure would
most likely have problems with which pharmacokinetic phase?
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.
The patient is complaining of a headache and asks the nurse which over-the-counter
medication form would work the fastest to help reduce the pain. Which medication form
