Temperature is 100.6°F (38.1°C), blood pressure is age appropriate, pulse is 128/min, respirations are 32/min, and oxygen saturation is 96% on room air. Physical examination confirms the key finding and shows no unrelated abnormality that would better explain the presentation.

Correct answer: A — Supportive care with hydration and oxygen when needed

The vignette describes Bronchiolitis, supported by infant with rhinorrhea, wheezing, tachypnea, and intercostal retractions. Supportive care with hydration and oxygen when needed is the single best answer because it matches the diagnostic or management priority in this clinical setting. The other choices are plausible alternatives in related presentations, but they do not best fit the timing, findings, and guideline-directed approach described here.
