Final answer:
The nurse should emphasize the importance of following the sublingual immunotherapy protocol, avoiding allergy medications before testing for accurate results, and managing exposure to allergens. The potential for initial mild allergic symptoms and the proper use of emergency treatments are also critical points to discuss with the client undergoing desensitization therapy for a ragweed pollen allergy.
Step-by-step explanation:
A client with an allergy to ragweed who is prescribed sublingual ragweed pollen extract should understand several important points emphasized by the nurse. Primarily, sublingual immunotherapy is a form of desensitization therapy that aims to gradually reduce the client's allergic reaction to ragweed pollen. The nurse should convey that while the client may experience some allergic symptoms initially, these are typically mild and should lessen over time as the immune system adapts. It's important for the client to adhere strictly to the protocol provided by the healthcare provider, taking the extract consistently and reporting any severe reactions or concerns.
Clients should also be aware that before allergy testing, they may be instructed to avoid allergy medications to ensure an accurate diagnosis, as certain medications can suppress the immune response, potentially leading to false-negative test results. A tailored approach, including avoiding ragweed exposure during high-pollen seasons and recognizing other allergenic plants like poison ivy, can help manage symptoms. Remembering the adage "leaves of three, let it be" will aid in avoiding poison ivy. It's also critical that the nurse reviews proper use of emergency treatments, such as epinephrine, in case of a severe reaction, and to discuss the follow-up care which may include antihistamines and corticosteroids.
