A 21-year-old primigravida at 38 weeks' gestation is in active labor. Her cervix is 5 cm dilated and fetal vertex is at +1 station. A tocodynamometer is done. What is the best description of the initial acid-base status of the fetus?
Understand the Problem
The question asks for the best description of the initial acid-base status of a fetus in a 21-year-old woman who is a primigravida at 38 weeks' gestation and in active labor, with a cervix dilated to 5 cm and the fetal vertex at +1 station, after a tocodynamometer is done.
Answer
Respiratory acidosis.
The best description of the initial acid-base status of the fetus is B. Respiratory acidosis.
Answer for screen readers
The best description of the initial acid-base status of the fetus is B. Respiratory acidosis.
More Information
During active labor, compression of the umbilical cord or contractions may reduce oxygen supply temporarily, leading to respiratory acidosis in the fetus.
Tips
It's important to distinguish between respiratory and metabolic acidosis. Respiratory acidosis is often due to temporary changes during labor.
