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 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.

Choice A rationale:

PaCO2 55 mm Hg on a blood gas indicates ineffective treatment. Normal PaCO2 levels range from 35-45 mm Hg.

Elevated PaCO2 (hypercapnia) suggests that the lungs are not effectively removing carbon dioxide from the body. This can be due to various factors, including:

Incomplete resolution of pneumonia Airway obstruction

Impaired respiratory muscle function

Choice B rationale:

Rhonchi in the right lung indicates ineffective treatment.

Rhonchi are coarse, rattling sounds heard in the lungs during auscultation.

They are often associated with mucus accumulation in the airways, which can occur in pneumonia.

The presence of rhonchi suggests that inflammation and mucus production persist, despite antibiotic and respiratory therapy.

Choice C rationale:

Oxygen saturation greater than 94% indicates effective treatment. Normal oxygen saturation levels are typically 95% or higher.

A saturation of 94% or above suggests that the lungs are able to effectively oxygenate the blood. This is a positive sign that the pneumonia is responding to treatment.

Choice D rationale:

Client ambulates without shortness of breath indicates effective treatment. Shortness of breath (dyspnea) is a common symptom of pneumonia.

It occurs when the lungs are unable to provide enough oxygen to the body, leading to a feeling of breathlessness.

The ability to ambulate without shortness of breath suggests that the pneumonia has improved and that the lungs are functioning more effectively.
