Which of the following factors can affect the absorption of parenterally administered drugs?
Blood flow to the injection site
The solubility of the drug
The size of the drug molecule
All above
The Correct Answer is D
Blood flow to the injection site, solubility, and size of drug molecule can all affect absorption of parenterally administered drugs. For example, drugs may be absorbed more readily if they are highly soluble in blood or if they are small enough to pass easily through capillary walls. Blood flow to the injection site can also affect absorption by altering the rate at which drugs are delivered to the absorption site.

Correct Answer is D
Explanation
