The nurse knows that which form of medication delivery results in the most predictable onset and most bioavailability to the client?
Correct answer
A
Rationale
Intravenous administration results in the most predictable onset and complete bioavailability, as the medication enters the bloodstream directly, bypassing absorption barriers. Oral, subcutaneous, and transdermal routes are subject to variable absorption rates and first-pass metabolism.
