Final answer:
"False", The statement refers to prolonged decelerations in fetal heart rate during labor, which can indicate fetal distress if contractions restrict blood flow to the fetus for too long, potentially requiring emergency interventions.
This correct answer is false.
Step-by-step explanation:
The statement 'These decelerations are >30 seconds from onset to nadir' refers to a pattern observed during labor where there is a decrease in fetal heart rate.
This can be indicative of fetal distress if the decelerations are significant and prolonged. During labor, each contraction can restrict oxygenated blood flow to the fetus, necessitating periods of relaxation for restoration of the blood flow.
If contractions are excessively long or strong, they could cause prolonged decelerations, leading to a lack of oxygen for the fetus and potential distress. In such cases, rapid intervention may be required, including emergency birth procedures such as vacuum, forceps, or Caesarian section.
This correct answer is false.
