What is the primary purpose of using terbutaline in labor for intrauterine resuscitation?

To stimulate uterine contractions

To improve placental blood flow

To decrease fetal heart rate variability

To prevent preterm labor

Answer and Explanation

The Correct Answer is B

A. To stimulate uterine contractions: Terbutaline is a tocolytic (a medication that relaxes the uterus), not a uterotonic. It is not used to stimulate contractions.

B. To improve placental blood flow: Terbutaline relaxes uterine muscles, decreasing contraction frequency and intensity, thereby improving placental blood flow. It is often used in intrauterine resuscitation when there is uteroplacental insufficiency and fetal distress due to excessive contractions (tachysystole).

C. To decrease fetal heart rate variability: Terbutaline does not directly affect fetal heart rate variability. It is used to reduce uterine contractions, which can secondarily improve fetal oxygenation.

D. To prevent preterm labor: While terbutaline can be used to delay preterm labor, in this context, it is being used for intrauterine resuscitation, not for preventing labor.

Correct Answer is C

Explanation

A. Maternal heart rate: While the maternal heart rate is important, it is not directly related to interpreting FHR patterns. However, it is necessary to differentiate between the maternal and fetal heart rate on the monitor.

B. Gestational age: While gestational age affects fetal heart rate (younger fetuses tend to have higher baseline rates), it is not a direct component of FHR interpretation.

C. Uterine contractions: Uterine contractions are crucial in FHR interpretation because they influence perfusion to the fetus. Decelerations occurring with contractions may indicate fetal distress (e.g., late decelerations suggest uteroplacental insufficiency).

D. Presence of accelerations and decelerations: Accelerations and decelerations provide key information about fetal well-being. Accelerations indicate fetal well-being, while decelerations may signal hypoxia, cord compression, or uteroplacental insufficiency.

A. Anomalies in fetal chromosomes B. Neural tube defects C. Cephalopelvic disproportion D. Fetal gender E. Rh incompatibility

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.
