A nurse is caring for a 2-year-old child in an acute care setting. Which of the following vital signs require immediate notification to a primary care provider?

Rationale: A. All vitals are within normal range for a 2-year-old; no immediate action is required. B. This child has marked tachypnea (62/min), which is significantly elevated for a 2-year-old (normal range: 22–37 breaths/min). This may indicate respiratory distress or metabolic acidosis and requires prompt evaluation. C. Vital signs are slightly elevated but still within normal limits for this age group. D. All vitals fall within expected ranges for a 2-year-old.
