The nurse is performing an assessment on a 7-year-old child who has symptoms of chronic watery eyes, sneezing, and clear nasal drainage. The nurse notices the presence of a transverse line across the bridge of the nose, dark blue shadows below the eyes, and a double crease on the lower eyelids. What does the nurse suspect is the cause of these signs and symptoms?

A. Lymphadenopathy: Enlarged lymph nodes typically indicate an immune response to infection or inflammation. While allergies can cause mild lymph node enlargement due to chronic irritation, they do not directly cause the characteristic facial signs described, such as the transverse nasal crease and allergic shiners. B. Nasal congestion: Nasal congestion is a symptom rather than a primary diagnosis. Although allergies can cause nasal congestion, the child exhibits additional hallmark signs of allergic rhinitis, including allergic shiners, Dennie-Morgan lines, and a nasal crease, suggesting a chronic allergic process rather than isolated congestion. C. Upper respiratory infection: Viral upper respiratory infections (URIs) can cause nasal congestion, sneezing, and watery eyes, but they are usually short-lived and accompanied by fever, malaise, or yellow-green nasal discharge. The presence of a nasal crease and allergic shiners suggests a chronic process like allergic rhinitis rather than an acute infection. D. Chronic allergies: The presence of a transverse nasal crease from frequent "allergic salute" rubbing, dark periorbital circles (allergic shiners) due to venous congestion, and Dennie-Morgan lines (double creases under the eyes) are classic findings in allergic rhinitis. These symptoms, along with watery eyes and clear nasal drainage, strongly indicate a chronic allergic condition rather than an infectious cause.
