Question

To be effective, a suspension must be shaken before administered.

Answer 1

That is true. A suspension is medication particles that are suspended in liquid.  That means they don't dissolve into a uniform solution. The particles have a tendency to settle at the bottom of a container. To assure that you are getting medication and not just the liquid preparation, one must shake a suspension well before administering.
