A nurse receives a report about a client who is in labor and is having contractions 3 min apart. Which of the following patterns should the nurse expect on the fetal monitoring tracing?

Contractions that last for 60 seconds each with a 2-min rest between contractions

Contractions that last for 60 seconds each with a 3-min rest between contractions

A contraction that lasts 3 min followed by a period of relaxation

Contractions that last 45 seconds each with a 2-min rest between contractions

Answer and Explanation

The Correct Answer is A

A. Contractions that last for 60 seconds each with a 2-min rest between contractions. If contractions are 3 minutes apart, this means the interval from the start of one contraction to the start of the next is 3 minutes. If each contraction lasts for 60 seconds, there will be a 2-minute rest period before the next contraction begins.

B. Contractions that last for 60 seconds each with a 3-min rest between contractions. This would indicate contractions occurring every 4 minutes, not every 3 minutes.

C. A contraction that lasts 3 min followed by a period of relaxation. A contraction lasting 3 minutes is abnormal and suggests uterine tachysystole, which can be dangerous.

D. Contractions that last 45 seconds each with a 2-min rest between contractions. If contractions last 45 seconds, the remaining rest period would be 2 min 15 sec, not exactly 2 minutes.

Correct Answer is ["A","B","D","E"]

Explanation

A. Anomalies in fetal chromosomes: Amniocentesis can diagnose chromosomal disorders such as Down syndrome, trisomy 18, and trisomy 13.

B. Neural tube defects: Amniocentesis measures alpha-fetoprotein (AFP) levels, which can indicate neural tube defects like spina bifida or anencephaly.

C. Cephalopelvic disproportion: Cephalopelvic disproportion (CPD) refers to a mismatch between fetal head size and maternal pelvis, which is assessed via ultrasound or clinical examination, not amniocentesis.

D. Fetal gender: Amniocentesis can determine fetal gender by analyzing fetal DNA, which is helpful in diagnosing sex-linked genetic disorders (e.g., hemophilia, Duchenne muscular dystrophy).

E. Rh incompatibility: Amniocentesis can assess bilirubin levels in amniotic fluid to determine the severity of hemolytic disease in Rh-incompatible pregnancies.

A. Gradual decrease in FHR that mirrors uterine contractions B. Abrupt decrease in FHR with rapid recovery C. Increase in FHR of at least 15 beats lasting at least 15 seconds D. Decrease in FHR after the peak of uterine contractions

Correct Answer is A

Explanation

A. Gradual decrease in FHR that mirrors uterine contractions. Early decelerations are caused by fetal head compression during contractions, leading to a gradual, uniform decrease in FHR that mirrors the contraction. This is a benign finding and does not require intervention.

B. Abrupt decrease in FHR with rapid recovery. This describes variable decelerations, which are caused by umbilical cord compression and require intervention.

C. Increase in FHR of at least 15 beats lasting at least 15 seconds. This describes accelerations, which are a reassuring sign of fetal well-being.

D. Decrease in FHR after the peak of uterine contractions. This describes late decelerations, which are associated with uteroplacental insufficiency and require intervention.
