What does BUCCAL refer to in terms of medication administration?

The term "buccal" specifically refers to the administration of medication in the space between the gums and the inner lining of the cheek. This method allows the medication to be absorbed through the mucous membranes directly into the bloodstream, bypassing the digestive system. This is particularly beneficial for drugs that are designed for rapid absorption and effects, as well as for substances that may be inactivated by stomach acid or first-pass metabolism by the liver.

The other options relate to different routes of administration or anatomical references but do not align with the exact definition of "buccal." For example, oral administration refers to taking medication by mouth but does not specifically indicate the cheek or gum area as the site of administration. Similarly, references to the left eye or both ears do not pertain to buccal administration. Thus, the choice that relates correctly to the term "buccal" is indeed the one concerning the cheek or gum.
