Which range is correct for typical newborn vital signs?

• A. RR 30-60 breaths/min; HR 110-160 bpm; BP 60-80/40-50; Temperature 97.7-99.5 F
• B. RR 20-40; HR 100-140; BP 50-70/30-40; Temperature 98.0-99.0 F
• C. RR 60-80; HR 150-190; BP 70-90/40-60; Temperature 96.0-97.0 F
• D. RR 40-70; HR 120-180; BP 60-80/40-50; Temperature 99.0-100.5 F

Answer: (A)

Newborn vital signs have higher heart and respiratory rates, lower blood pressure, and a slightly cooler average temperature than adults. The combination that fits these norms is a respiratory rate around 30–60 breaths per minute, a heart rate about 110–160 bpm, blood pressure near 60–80 systolic/40–50 diastolic, and a temperature roughly 97.7–99.5°F. This set aligns with typical stable newborn physiology: the respiratory system is active but can be irregular and faster than adults, the heart works harder to support circulation, and the blood pressure is still relatively low as the vessels adapt after birth. The other ranges show values outside these common newborn norms in at least one parameter, making them less representative of healthy newborn vitals.
