Q

Infants have a _____ Extracellular fluid and _____ TBW. This leads to _____ plasma concentration of water soluble drugs and _____ plasma concentration of lipid soluble drugs.

A

Larger, greater

lower plasma concentration (diluted) H2O-soluble drugs – higher dose; lipid-soluble has higher plasma concentration due to decreased fat & muscle
