What assessment finding would suggest an upper respiratory infection in a toddler?

Nasal congestion and fever are classic signs associated with upper respiratory infections in toddlers. Upper respiratory infections, often referred to as the common cold, frequently present with symptoms such as nasal congestion due to inflammation and mucus production in the nasal passages, along with fever as the body responds to the viral infection. These findings are particularly relevant in toddlers, who may also exhibit irritability and reduced appetite.

The other symptoms listed do not specifically point toward an upper respiratory infection. Cough and wheezing might suggest lower respiratory involvement, such as bronchitis or asthma, rather than an upper respiratory issue. Vomiting and diarrhea can indicate gastrointestinal infections or other systemic illnesses, not primarily respiratory problems. Similarly, a rash and joint pain might suggest allergic reactions or inflammatory conditions rather than an upper respiratory infection. Thus, the presence of nasal congestion and fever aligns closely with the typical presentation of upper respiratory infections in toddlers.
