What is the normal blood pressure for a preterm infant?

The normal blood pressure for a preterm infant is generally considered to fall within the range of 50/30 mmHg. This choice accurately reflects the typical blood pressure values observed in preterm infants, who often have lower blood pressure compared to full-term infants and older children due to their underdeveloped cardiovascular systems.

In premature infants, maintaining adequate blood pressure is crucial for proper organ perfusion and preventing complications. The values cited align with clinical guidelines and literature that outline the expected blood pressure ranges for preterm infants, often expressed in terms of gestational age. Understanding these benchmarks is essential for healthcare providers when assessing the cardiovascular status of these vulnerable patients.

The other choices represent blood pressure values that would be atypical for preterm infants, either being too low or too high, which underscores the importance of monitoring and evaluating preterm infants carefully within the context of their developmental stage.
