A client in labor is agitated and nervous about the birth of her child. The nurse explains to the client that fear and anxiety cause the release of certain compounds that can prolong labor. The nurse is referring to which compounds?
Choices:

Prostaglandin.

Catecholamines.

Oxytocin.

Orexin.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Prostaglandins are involved in labor but primarily act to ripen the cervix and induce uterine contractions, not prolong labor. They are produced by the fetus and placenta during pregnancy.

Choice B rationale

Catecholamines, such as epinephrine and norepinephrine, are released in response to stress and anxiety, leading to vasoconstriction, reduced blood flow to the uterus, and prolonged labor. They are produced by the adrenal glands.

Choice C rationale

Oxytocin is a hormone that stimulates uterine contractions and accelerates labor. It is often administered to induce or augment labor, rather than prolong it. It is produced in the hypothalamus.

Choice D rationale

Orexin, also known as hypocretin, is involved in regulating arousal, wakefulness, and appetite, but has no direct role in labor. It is produced in the hypothalamus.

Correct Answer is A

Explanation

Choice A rationale

A reactive non-stress test shows at least two accelerations of the fetal heart rate, 15 beats per minute above baseline, lasting 15 seconds or more within 20 minutes, indicating fetal well-being.

Choice B rationale

A non-reactive non-stress test lacks sufficient accelerations in the fetal heart rate. This may require further assessment, such as a biophysical profile, to ensure fetal well-being.

A. Cord compression. B. Head compression. C. Placental insufficiency. D. Reactive NST.

Correct Answer is B

Explanation

Choice A rationale

Cord compression typically causes variable decelerations on the monitor, which are abrupt decreases in fetal heart rate, often with a U, V, or W shape.

Choice B rationale

Head compression leads to early decelerations, which are gradual decreases in fetal heart rate occurring with contractions. This pattern indicates head compression during labor.

Choice C rationale

Placental insufficiency results in late decelerations, where the fetal heart rate decreases after the peak of a contraction. This pattern suggests compromised placental blood flow.

Choice D rationale

Reactive NST (Non-Stress Test) indicates fetal well-being and is characterized by fetal heart rate accelerations, not decelerations.
