The implementation that the nurse may perform for a patient with pruritus without the physician's orders to:

A. Oatmeal baths can soothe pruritic skin by moisturizing and providing a protective barrier. However, depending on institutional policy, special preparations or products may require a provider’s order. The nurse may not independently initiate an oatmeal bath without confirming facility guidelines. B. Applying a lubricant or moisturizer to unbroken skin is an independent nursing intervention. It is safe, noninvasive, and helps alleviate itching by maintaining skin hydration, protecting the skin barrier, and reducing irritation. This intervention can be implemented immediately without a physician’s order and is considered standard nursing care for managing mild pruritus or dry skin. C. Topical corticosteroids are prescription medications and can have significant side effects, including skin atrophy, systemic absorption, and adrenal suppression. Nurses cannot apply these agents without a provider’s order, as doing so would exceed their independent scope of practice. D. Antihistamines are pharmacologic agents requiring a provider’s prescription. While effective in reducing pruritus by blocking histamine receptors, they are not independent nursing interventions and must be administered according to an order.
