The healthcare professional prepares to administer buccal medication. The medicine should be placed...
- A. On the client's skin
- B. Between the client's cheeks and gums
- C. Under the client's tongue
- D. On the client's conjunctiva
Correct Answer: B
Rationale: Buccal medication is administered by placing it between the client's cheeks and gums. This route allows for the medication to be absorbed through the mucous membranes in the mouth, providing a rapid onset of action compared to oral ingestion. Placing the medication under the tongue (sublingual) allows for absorption through the sublingual mucosa, not the buccal mucosa. Placing medication on the skin or the conjunctiva is not appropriate for buccal administration.
