Why are sublingual and buccal medications rapidly absorbed?
They are metabolized in the liver.
Their action is located in the mouth.
These drugs pass directly into systemic circulation.
Blood flow is diminished in these sites.
The Correct Answer is C
Sublingual and buccal medications are rapidly absorbed because they are placed under the tongue or between the cheek and gum, where they dissolve and are absorbed directly into the bloodstream through the mucous membranes in the mouth. This allows for rapid absorption and bypasses the liver’s first-pass metabolism.

Correct Answer is D
Explanation
When administering ophthalmic drops, the nurse should hold the dropper 2 cm (3/4 inch) above the lower conjunctival sac and instill the prescribed number of drops into the sac. The client should be instructed to look up and away from the dropper while the drops are being instilled.
Correct Answer is B
Explanation
The correct answer is choiceb. Monitor the serum medication levels.
Choice A rationale:
Administering gentamicin with food is not necessary and does not minimize the risk of adverse effects. Gentamicin is typically given intravenously or intramuscularly, and food does not impact its administration or absorption.
Choice B rationale:
Monitoring the serum medication levels is crucial when administering gentamicin. Gentamicin has a narrow therapeutic index, meaning the difference between a therapeutic dose and a toxic dose is small. Regular monitoring helps ensure the drug remains within the safe and effective range, reducing the risk of nephrotoxicity and ototoxicity.
Choice C rationale:
Limiting the client’s fluid intake is not recommended. Adequate hydration is important to help prevent nephrotoxicity, a known adverse effect of gentamicin. Ensuring the client has sufficient fluid intake can help protect kidney function.
Choice D rationale:
Instructing the client to report agitation is not directly related to minimizing the risk of adverse effects of gentamicin. While it is important for clients to report any unusual symptoms, agitation is not a common adverse effect of gentamicin. Monitoring for signs of nephrotoxicity (e.g., decreased urine output) and ototoxicity (e.g., hearing loss, tinnitus) is more relevant.
