The nurse is reading the results of non-stress test (NST) strips completed that day. Which of the following strips meets the criteria for a reactive NST? Select one:

Choice A Reason: "If I try to talk to my partner during a contraction, I can't." This is an incorrect answer that indicates a sign of true labor, not false labor. True labor is a condition where there are regular and painful uterine contractions that cause cervical dilation and effacement, and lead to delivery of the baby and placenta. True labor contractions are usually strong and consistent, and they tend to increase or persist with activity or position changes. True labor contractions can be so intense that they interfere with speech or breathing.

Choice B Reason: ) "My contractions slow down when I walk around." This is because this statement by the client would lead the nurse to suspect that the woman is experiencing false labor, which is also known as Braxton Hicks contractions or practice contractions. False labor is a condition where there are irregular and painless uterine contractions that do not cause cervical dilation or effacement. False labor can occur throughout pregnancy, but it becomes more noticeable and frequent in late pregnancy. False labor contractions are usually weak and inconsistent, and they tend to decrease or stop with activity or position changes.

Choice C Reason: "I feel contractions start mostly in my back and they sweep around to the top of my abdomen." This is an incorrect answer that indicates a sign of true labor, not false labor. True labor contractions usually start in the lower back and radiate to the lower abdomen or groin, following a wave-like patern. False labor contractions are more likely to be felt in the upper abdomen or sides, without a clear patern.

Choice D Reason: "My contractions are about 6 minutes apart and regular." This is an incorrect answer that indicates a sign of true labor, not false labor. True labor contractions usually have a regular frequency and duration, and they become closer and longer as labor progresses. False labor contractions are more likely to have an irregular frequency and duration, and they do not change significantly over time.

Choice A Reason: Shoulder dystocia. This is an incorrect answer that describes a different obstetric complication. Shoulder dystocia is a condition where the baby's shoulder gets stuck behind the mother's pubic bone during delivery, which can cause nerve injury, fracture, or asphyxia to the baby. Shoulder dystocia does not cause fetal bradycardia, abdominal pain, or vaginal bleeding.

Choice B Reason: Placental abruption. This is a correct answer that explains the symptoms of fetal bradycardia, abdominal pain, and vaginal bleeding in a woman with a history of crack cocaine use. Placental abruption. This is because placental abruption is a condition where the placenta separates from the uterine wall before delivery, which can cause fetal distress, maternal hemorrhage, and shock. Placental abruption can be triggered by maternal hypertension, trauma, or substance abuse, such as crack cocaine.

Choice C Reason: Anaphylactoid syndrome of pregnancy. This is an incorrect answer that refers to a rare and fatal condition also known as amniotic fluid embolism. Anaphylactoid syndrome of pregnancy is a condition where amniotic fluid enters into the maternal bloodstream and causes an allergic reaction, which can lead to respiratory failure, cardiac arrest, coagulopathy, and coma. Anaphylactoid syndrome of pregnancy does not cause fetal bradycardia or vaginal bleeding.

Choice D Reason: Placenta previa. This is an incorrect answer that indicates another placental disorder. Placenta previa is a condition where the placenta covers or is near the cervix, which can cause painless bright red bleeding during pregnancy or labor. Placenta previa does not cause fetal bradycardia or abdominal pain.
