A reliable indication of a nonacidotic fetus is an elicited acceleration corresponding to what minimum cord pH?

• A. 6.9
• B. 7.0
• C. 7.19
• D. 7.4

Answer: (C)

A reliable indication of a nonacidotic fetus is reflected in a cord pH that suggests sufficient oxygenation and normal acid-base balance. A pH of 7.19 indicates that the fetus is more likely to be in a nonacidotic state, as it is above the threshold typically associated with fetal acidosis. A pH lower than this value, particularly at or below 7.0, would signify a risk of acidosis, leading to potential issues with fetal well-being. In general, the normal range for umbilical cord blood pH is between approximately 7.20 and 7.40, with values below this suggesting increasing concern for fetal distress. Therefore, a pH of 7.19 represents a critical threshold indicating that while the fetus may be well, it is approaching the lower limits of normal, hence signifying a stable condition rather than a nonacidotic one. It is important to monitor the situation closely, but it is a positive sign in comparison to significantly lower pH values.
