An infant who receives a drug that does not produce CNS side effects in adults exhibits drowsiness and sedation. The nurse understands that this is because of differences in which phy-siologic system in infants and adults?
a. Blood-brain barrier
b. First-pass effect
c. Gastrointestinal absorption
d. Renal filtration
A
The blood-brain barrier is not fully developed at birth, making infants much more sensitive to CNS drugs than older children and adults. CNS symptoms may include sedation and drowsiness. The first-past effect and GI absorption affect metabolism and absorption of drugs, and renal fil-tration affects elimination of drugs, all of which may alter drug levels.
