The practical nurse applies a preparation with keratolytic properties to both legs of a client with psoriasis. Which finding indicates the desired effect has been achieved?
No purulent drainage present from lesions on the legs
Affected areas are free of localized redness and swelling
Scaly areas of the skin appear softer with less peeling
Full range of motion without pain of lower extremity joints . .
The Correct Answer is C
Choice C rationale
Keratolytics are medications designed to dissolve skin flakes and scales. In the treatment of psoriasis, a condition characterized by thick, scaly patches of skin, the desired effect of a keratolytic would be to soften and reduce these scales.
Choice A rationale
While no purulent drainage present from lesions on the legs could be a positive sign in the treatment of psoriasis, it is not a direct result of the keratolytic properties of the applied preparation.
Choice B rationale
Affected areas being free of localized redness and swelling could be a positive sign in the treatment of psoriasis, but it is not a direct result of the keratolytic properties of the applied preparation.
Choice D rationale
Full range of motion without pain of lower extremity joints is not a direct result of the keratolytic properties of the applied preparation. It could be a positive sign in the overall treatment of psoriasis, but it is not directly related to the use of a keratolytic.

Correct Answer is A
Explanation
Choice A rationale
Clearing the nose with a tissue prior to the instillation of nasal drops can help to remove
mucus and other obstructions, allowing the medication to reach the nasal passages more
effectively15.
Choice B rationale
Deep inhalation through the nose is not typically recommended prior to the instillation of
nasal drops. It could potentially draw the medication deeper into the nasal passages or into the
throat, rather than allowing it to remain in the intended area15.
Choice C rationale
Holding the breath temporarily is not typically necessary or recommended prior to the
instillation of nasal drops15.
Choice D rationale
the nasal passages, but it is not as effective or recommended as using a tissue to clear the
nose15.
Correct Answer is C
Explanation
The correct answer is choice C.
Choice A rationale:
Wearing protective clothing when in direct sunlight is not specifically related to taking alendronate. This advice is more relevant for medications that increase photosensitivity, which is not a known side effect of alendronate.
Choice B rationale:
Sucking on hard candy to increase oral secretions is not necessary for patients taking alendronate. This advice is typically given to patients experiencing dry mouth, which is not a common side effect of alendronate.
Choice C rationale:
Drinking 8 ounces (240 mL) of water with each dose of alendronate is crucial. This helps ensure the medication reaches the stomach quickly and reduces the risk of esophageal irritation or ulcers.
Choice D rationale:
Laying supine for 30 minutes after taking alendronate is incorrect. Patients should remain upright (sitting or standing) for at least 30 minutes after taking the medication to prevent esophageal irritation and ensure the medication reaches the stomach properly.
