Which of the following are indications for performing a contraction stress test in pregnancy?

Choice A rationaleIntrauterine growth restriction (IUGR) is an indication for a contraction stress test. It assesses fetal response to uterine contractions, identifying potential placental insufficiency.Choice B rationaleA normal biophysical profile indicates no need for a contraction stress test. It assesses fetal well-being, and normal results suggest no immediate concerns.Choice C rationalePlacental abruption is a contraindication for a contraction stress test. Inducing contractions can exacerbate placental separation, risking maternal and fetal health.Choice D rationaleDecreased fetal movements warrant a contraction stress test. It evaluates fetal response to contractions, detecting possible hypoxia or compromised fetal condition.Choice E rationalePost-term pregnancy (>42 weeks) is an indication for a contraction stress test. It assesses placental function and fetal well-being as prolonged gestation increases risks.
