For a client with an NG tube receiving sublingual medication, what action should the nurse take?

For a client with an NG tube who is receiving sublingual medication, the appropriate action is to administer the medication under the client's tongue. Sublingual medications are formulated to dissolve quickly and be absorbed directly into the bloodstream through the mucous membranes under the tongue. This route bypasses the gastrointestinal tract, allowing for faster therapeutic effects.

In this scenario, administering the medication sublingually ensures that it maintains its intended pharmacokinetic properties and achieves the desired effect without interference from degradation that could occur if taken through an NG tube.

Other methods, such as crushing the medication or administering it through the NG tube, can compromise the medication's efficacy and may cause irritation to the gastrointestinal mucosa. Additionally, giving the medication orally with a small sip of water is inappropriate for sublingual doses, as the wet environment in the mouth would not allow it to dissolve correctly and achieve the necessary absorption.
