What is the systolic blood pressure range for neonates (0 to 1 month)?

• A. 50 to 70
• B. 60 to 80
• C. 40 to 60
• D. 70 to 90

Answer: (A)

Neonates have relatively low systolic blood pressure because their cardiovascular system is still maturing. In the first month of life, a typical systolic BP sits around 50 to 70 mmHg. This lower range reflects the newborn’s immature vascular tone and circulating volume, which gradually increase as the infant grows. Among the options, 50–70 mmHg best matches the common reference for a newborn in the 0 to 1 month period. The other ranges either exceed what is usually observed in this age group or are lower/higher than what’s typical for a newborn. Keep in mind that measurements can vary with cuff size and technique, but 50–70 mmHg is the best fit for this age range.
