Correct Answer is D

Explanation

A. Dissolve the tablet in 118 mL (4 oz) liquid: This option is incorrect because buccal tablets are specifically designed to dissolve in the mouth without liquid. Using liquid can dilute the medication and hinder effective absorption.

B. Have the client chew the medication before swallowing: Chewing the buccal tablet is not appropriate, as it can lead to rapid release and loss of the intended slow absorption through the mucous membranes. This method undermines the effectiveness of the medication.

C. Mix the medication in 5 mL (1 tsp) soft food: This action is also incorrect, as mixing the buccal tablet with food may interfere with its absorption. Buccal medications are intended to dissolve between the cheek and gums for optimal effect.

D. Place the tablet between the client's cheek and gums: This is the correct method for administering a buccal tablet. This placement allows the medication to dissolve slowly and be absorbed effectively through the buccal mucosa, providing the desired therapeutic effect.

Correct Answer is ["0.75"]
