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
BUN stands for Blood Urea Nitrogen, and it is a laboratory test that measures the amount of nitrogen in the blood that comes from urea, which is a waste product of protein metabolism. Elevated BUN levels indicate impaired kidney function. Amphotericin B is known to be potentially nephrotoxic, which means that it can cause damage to the kidneys. Therefore, the nurse should report an elevated BUN level to the provider before initiating the medication to ensure the safety of the client. Potassium, glucose, and sodium levels are within normal range and do not require intervention in this scenario.
Correct Answer is D
Explanation
A.Sterile technique should ideally be used when handling the distal portion of the eyedropper to prevent introducing pathogens into the eye, as the eye is a sensitive area susceptible to infection.
B.When cleaning the eye, it is recommended to wipe from the inner canthus to the outer canthus to avoid bringing contaminants from the outer area closer to the tear duct, which reduces the risk of infection.
C.Applying pressure to the bridge of the nose is ineffective for preventing systemic absorption of the medication. Instead, pressure should be applied to the inner canthus (the nasolacrimal duct area) for about 1-2 minutes after instillation.
D.The correct technique for administering eye drops involves placing the prescribed number of drops into the conjunctival sac, not directly onto the cornea, as this can cause irritation and discomfort. Administering drops into the conjunctival sac allows for better absorption of the medication.
