Question: 1 / 400

What is the normal HCO3 level in the umbilical artery?

18 to 20

20 to 21

22 to 24

The normal bicarbonate (HCO3) level in the umbilical artery is typically in the range of 22 to 24 mEq/L. This level is important as it reflects the acid-base balance and metabolic status of the fetus, indicating how well the fetus is handling carbon dioxide and maintaining appropriate blood pH.

Maintaining this range is critical for fetal well-being, as deviations can suggest issues like acidosis or alkalosis, which may indicate fetal distress. Evaluating HCO3 levels helps healthcare providers assess the metabolic status of the fetus, especially during labor and delivery, making it an essential parameter in advanced fetal monitoring.

The other options do not accurately reflect the established normal range in the umbilical artery, making the one selected the most appropriate choice for understanding normal fetal metabolic function.
