A client with psoriasis returns to the clinic reporting the persistence of several silvery, scaly areas on the elbows and palms that frequently burn and sometimes bleed. Which prescription should the nurse teach the client to use for the skin condition?

A.

Topical antifungal.

B.

Colloidal oatmeal-based lotion.

C.

Topical corticosteroids.

D.

Topical analgesics.

Answer and Explanation

The Correct Answer is C

Choice A rationale

 

Topical antifungals are used to treat fungal infections and are not effective for psoriasis, which is an autoimmune condition.

 

Choice B rationale

 

Colloidal oatmeal-based lotion can help soothe the skin but does not address the underlying inflammation and scaling associated with psoriasis.

 

Choice C rationale

 

Topical corticosteroids are the mainstay of treatment for psoriasis. They help reduce inflammation, itching, and redness associated with psoriatic plaques.

 

Choice D rationale

 

Topical analgesics can help relieve pain but do not address the underlying inflammation and scaling associated with psoriasis.

Correct Answer is A

Explanation

Choice A rationale

Lactulose is a synthetic sugar used to treat hepatic encephalopathy by reducing the absorption of ammonia in the intestines. Ammonia is a neurotoxin that can impair mental status in patients with liver dysfunction. By decreasing ammonia levels, lactulose helps improve cognitive function and mental status in patients with hepatic encephalopathy.

Choice B rationale

While lactulose can cause diarrhea as a side effect, the therapeutic goal in hepatic encephalopathy is not to reduce the number of liquid stools but to lower ammonia levels in the blood. The reduction in ammonia levels leads to improved mental status, not necessarily a reduction in liquid stools.

Choice C rationale

The ability to ambulate independently is not a direct therapeutic response to lactulose. The primary goal of lactulose therapy in hepatic encephalopathy is to improve mental status by reducing ammonia levels, not to enhance physical mobility.

Choice D rationale

Lactulose does not have a direct effect on urine output. Its primary mechanism of action is to reduce ammonia absorption in the intestines, thereby improving mental status in patients with hepatic encephalopathy.

Correct Answer is A

Explanation

Choice A rationale

Suctioning to clear secretions from the airway is the first intervention to implement. The client’s weak cough effort and use of accessory muscles to breathe suggest the presence of retained respiratory secretions, which can impair breathing and lead to further respiratory compromise.

Choice B rationale

Offering a prescribed PRN analgesic is important for overall comfort but is not the most immediate intervention needed to address the client’s respiratory distress.

Choice C rationale

Obtaining arterial blood gases may provide valuable information but is not the most immediate intervention needed to address the client’s respiratory distress.

Choice D rationale

Administering a prescribed antipyretic is not the most immediate intervention needed to address the client’s respiratory distress.
