Step-by-step explanation:
A positive stress test in the context of antepartum testing refers to a result indicating possible fetal distress or an increased risk to the baby during pregnancy. The stress test is a common procedure performed to assess fetal well-being and involves monitoring the baby's heart rate in response to uterine contractions or other stressors. A positive stress test may suggest inadequate oxygen supply to the baby or other complications that require further evaluation and medical intervention.
