When interpreting fetal heart rate patterns, what other information is considered in addition to baseline and variability?

A.

Maternal heart rate

B.

Gestational age

C.

Uterine contractions

D.

Presence of accelerations and decelerations

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is A

Explanation

A. Parity: In GPTAL (Gravida, Parity, Term, Abortions, Living children), "P" refers to parity, which indicates the number of pregnancies carried to 20 weeks or beyond, regardless of outcome.

B. Postpartum: "Postpartum" refers to the period after childbirth and is not part of the GPTAL system.

C. Primigravida: Primigravida refers to a woman who is pregnant for the first time, which is represented by "G" (Gravida) in GPTAL, not "P."

D. Presentation: "Presentation" refers to the fetal part entering the birth canal first (e.g., cephalic, breech) and is unrelated to GPTAL.

Correct Answer is C

Explanation

A. Maternal bradycardia: Late decelerations are caused by uteroplacental insufficiency, not maternal heart rate changes.

B. Fetal head compression: Fetal head compression causes early decelerations, which are benign and mirror contractions. Late decelerations occur after contractions and indicate a more serious issue.

C. Uteroplacental insufficiency: Late decelerations occur due to decreased oxygenation from poor placental perfusion (uteroplacental insufficiency). Common causes include maternal hypotension, post-term pregnancy, uterine tachysystole, and placental abruption.

D. Umbilical cord compression: Umbilical cord compression causes variable decelerations, not late decelerations.
