What are normal vital signs for newborn to 6 months?

• A. HR: 100-160, RR: 25-60, SBP: >60
• B. HR: 80-150, RR: 20-40, SBP: >70
• C. HR: 60-100, RR: 15-25, SBP: >90
• D. HR: 120-180, RR: 30-70, SBP: >50

Answer: (A)

For newborns through six months, vital signs have higher normal ranges than older children, reflecting a faster metabolism and smaller body size. A typical resting heart rate is about 100–160 beats per minute, and the breathing rate is about 25–60 breaths per minute. Systolic blood pressure tends to be above 60 mmHg as a lower bound in this age group. These ranges accommodate normal variation from activity, fever, or distress—crying or fever can raise heart rate and respiratory rate temporarily but remain within acceptable limits if not extreme. Values outside these patterns consistently can signal trouble, such as persistent tachycardia or tachypnea or hypotension. The set of values described here matches the standard expectations for infants from birth to six months, making it the best fit among the options.
