An $8$-month-old girl is brought to a family medicine clinic in mid-December due to a persistent cough and noisy breathing. Her mother reports that the child developed a runny nose, low-grade fever, and mild nasal congestion four days ago. Yesterday, the nasal discharge became thick, and the child developed a "tight" cough. She has no prior episodes of wheezing and was born at term without complications. She has been feeding well and producing a normal number of wet diapers. Vital signs are temperature $37.8^\circ\text{C}$ ($100.0^\circ\text{F}$), heart rate $125\text{/min}$, respiratory rate $44\text{/min}$, and oxygen saturation $96\%$ on room air.
