Which term corresponds to the definition 'Process of drug entering the bloodstream'?

• A. Medication absorption
• B. Solvent
• C. Standing orders
• D. Synthetic

Answer: (A)

Absorption is the step where a drug moves from its site of administration into the bloodstream, becoming available for distribution and effect. This is the term that captures the idea of the drug entering systemic circulation, which is essential for it to reach target tissues. Medication absorption specifically describes this process. A solvent is simply the liquid that dissolves the drug, not the movement into blood; standing orders are pre‑approved clinical guidelines; synthetic describes origin or type of substance, not how a drug enters the bloodstream. Routes of administration influence absorption rate and extent—for example, IV administration bypasses absorption entirely by delivering the drug directly into circulation, while oral absorption involves dissolution and passage through the GI tract.
