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?
Colloidal oatmeal-based lotion.
Topical corticosteroids.
Topical analgesics.
Topical antifungal.
The Correct Answer is B
A Colloidal oatmeal-based lotion: Colloidal oatmeal can help to reduce itching and swelling, all while hydrating the skin. It is often used to soothe irritated skin and can be incorporated into a skincare routine through oatmeal baths or oatmeal-infused moisturizers. However, it is typically used as a complementary treatment and may not be sufficient to manage psoriasis symptoms on its own.
B Topical corticosteroids: These are an essential tool for treating inflammatory skin conditions such as psoriasis34. They work by reducing inflammation and slowing down the production of skin cells, which helps to alleviate symptoms such as redness, itching, and scaling. Topical corticosteroids are often the first line of treatment for mild to moderate psoriasis.
C. Topical analgesics: These are primarily used to relieve pain. While they may provide some relief from discomfort associated with psoriasis, they do not address the underlying inflammation and rapid skin cell production that characterize this condition.
D Topical antifungal: Antifungal agents are typically used to treat conditions like seborrheic dermatitis and scalp psoriasis, or in areas where psoriasis involves folds in the skin, where there is an increased potential for localized infection. However, they are not typically used as a primary treatment for psoriasis.

Correct Answer is B
Explanation
Choice A rationale:
Wild rice is naturally gluten-free. It is not a grain, but rather a semi-aquatic grass seed. It is safe for individuals with celiac disease to consume.
Wild rice is a good source of nutrients. It is high in fiber, protein, and antioxidants, and it contains a variety of vitamins and minerals, including manganese, phosphorus, magnesium, and zinc. These nutrients can help to support overall health and well-being.
Wild rice can be a versatile ingredient in many dishes. It can be used in salads, soups, stews, pilafs, and even desserts.
Choice B rationale:
Oatmeal is not gluten-free. It is made from oats, which are a type of cereal grain that contains gluten. Individuals with celiac disease must avoid gluten, as it can trigger an autoimmune reaction that damages the small intestine.
Even small amounts of gluten can cause harm. Consuming even a small amount of oatmeal can cause symptoms such as abdominal pain, bloating, diarrhea, fatigue, and headache in individuals with celiac disease.
Long-term damage can occur. If individuals with celiac disease continue to consume gluten, it can lead to long-term health problems, such as malnutrition, osteoporosis, and infertility.
Choice C rationale:
Corn chips are typically gluten-free. However, it is important to check the label to be sure, as some brands may contain gluten- containing ingredients, such as wheat flour or barley malt.
Reading labels is essential. Individuals with celiac disease should always read food labels carefully to ensure that products are gluten-free.
Choice D rationale:
Potatoes are naturally gluten-free. They are a safe and healthy food choice for individuals with celiac disease.
Potatoes are a versatile and nutritious food. They are a good source of carbohydrates, fiber, potassium, vitamin C, and other nutrients.
Correct Answer is A
Explanation
Choice A rationale:
Lactulose is a non-absorbable disaccharide that is metabolized by bacteria in the colon to produce lactic acid and acetic acid. These acids acidify the colon, which traps ammonia (NH3) in the colon and converts it to ammonium (NH4+). Ammonium is not absorbed by the colon and is excreted in the stool. This ammonia-lowering effect is the primary mechanism by which lactulose improves mental status in patients with hepatic encephalopathy.
Hepatic encephalopathy is a neuropsychiatric syndrome that occurs in patients with severe liver disease. It is caused by the buildup of ammonia in the blood, which can cross the blood-brain barrier and cause cerebral edema and impaired brain function.
The clinical manifestations of hepatic encephalopathy range from mild confusion and personality changes to coma. Improved mental status is a key therapeutic goal in the treatment of hepatic encephalopathy.
Studies have shown that lactulose can improve mental status in patients with hepatic encephalopathy. A meta-analysis of 11 randomized controlled trials found that lactulose was associated with a significant improvement in mental status compared to placebo.
The improvement in mental status is typically seen within 24 to 48 hours of starting lactulose therapy.
Choice B rationale:
Increased urine output is not a direct therapeutic effect of lactulose. Lactulose can cause diarrhea, which can lead to increased urine output due to fluid loss. However, this is not the primary mechanism by which lactulose improves mental status in patients with hepatic encephalopathy.
Choice C rationale:
Reduction in the number of liquid stools is a common side effect of lactulose. However, it is not a therapeutic goal in the treatment of hepatic encephalopathy. The goal of lactulose therapy is to improve mental status by lowering ammonia levels in the blood.
Choice D rationale:
Ability to ambulate independently is not a direct therapeutic effect of lactulose. Lactulose can improve mental status, which may indirectly lead to improved ambulation in some patients. However, this is not the primary mechanism by which lactulose works.
