is most appropriate?
A. Administer the medication as prescribed.
B. Notify the provider before administering the medication.
C. Crush the medication and mix it with applesauce.
D. Double the dose to compensate for poor absorption.

absorption and increase the risk of aspiration. The nurse should
notify the provider to determine whether an alternative route
of administration is needed.
