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:
Hemoccult test on sputum collected from hemoptysis is not a diagnostic test for TB. It is a test for blood in the stool, which can be a symptom of TB but is not specific to TB.
Hemoptysis, or coughing up blood, can occur in various conditions, including bronchitis, pneumonia, lung cancer, and TB. The Hemoccult test cannot differentiate between these causes, making it an unreliable test for diagnosing TB.
Choice B rationale:
Sputum culture positive for Mycobacterium tuberculosis is the definitive diagnostic test for TB.
It involves collecting a sample of sputum, which is the mucus coughed up from the lungs, and culturing it in a laboratory to see if Mycobacterium tuberculosis, the bacteria that causes TB, grows.
This test is highly specific for TB, meaning that a positive result is almost always indicative of TB infection. It is also sensitive, meaning that it can detect TB infection even when there are few bacteria present.
Choice C rationale:
Positive purified protein derivative (PPD) skin test indicates exposure to TB but does not confirm active infection.
The PPD skin test involves injecting a small amount of tuberculin, a protein derived from Mycobacterium tuberculosis, into the skin.
If a person has been exposed to TB, their immune system will react to the tuberculin, causing a raised red bump to appear at the injection site.
However, a positive PPD skin test does not necessarily mean that a person has active TB infection.
It could also mean that they have been exposed to TB in the past but have successfully fought off the infection. Further testing, such as a sputum culture, is needed to confirm the diagnosis of TB.
Choice D rationale:
Chest X-ray or computed tomography (CT) can show abnormalities in the lungs that are suggestive of TB, but they cannot definitively diagnose TB.
These imaging tests can reveal changes in the lungs, such as nodules, inflammation, or fluid buildup, which can be caused by TB or other conditions.
Therefore, a chest X-ray or CT scan alone is not sufficient to diagnose TB. A sputum culture is still needed to confirm the diagnosis.
Correct Answer is C
Explanation
Rationale for Choice A:
Serum Helicobacter pylori (H. pylori) antibody results are not directly relevant to the diagnosis or management of acute pancreatitis. While H. pylori infection can cause gastritis and peptic ulcers, it is not a common cause of pancreatitis.
Urine output amounts are important to monitor in patients with pancreatitis to assess for dehydration and kidney function. However, they are not as specific to the diagnosis of pancreatitis as other findings.
Rationale for Choice B:
Reports of chronic constipation are not typically associated with acute pancreatitis.
Serum gastrin levels are used to diagnose conditions such as Zollinger-Ellison syndrome, which is characterized by excessive acid production in the stomach. They are not relevant to the diagnosis of pancreatitis.
Rationale for Choice C:
Severity of nausea and vomiting are key symptoms of pancreatitis. The severity of these symptoms can help to gauge the severity of the pancreatitis and guide treatment decisions.
Serum amylase results are a highly sensitive and specific marker for pancreatitis. Elevated levels of amylase in the blood strongly suggest the presence of pancreatitis.
Rationale for Choice D:
Presence of bowel sounds can be variable in patients with pancreatitis and are not always reliable indicators of the severity of the condition.
Degree of abdominal pain is a subjective symptom that can be difficult to assess accurately. While it is an important symptom of pancreatitis, it is not as objective as other findings such as serum amylase levels.
Therefore, the most valuable information to report to the healthcare provider in this case is the severity of nausea and vomiting and serum amylase results.
