What could be the result of fetal head compression?

Uteroplacental insufficiency.

Spontaneous rupture of membranes.

Altered fetal cerebral blood flow.

Umbilical cord compression.

Answer and Explanation

The Correct Answer is A

Choice A rationale: Uteroplacental insufficiency causes late decelerations due to reduced oxygenation, not mechanical pressure. It reflects placental dysfunction, not direct cranial compression effects.

Choice B rationale: Spontaneous rupture of membranes increases infection and labor risk but does not directly alter cerebral perfusion or trigger vagal responses linked to head compression.

Choice C rationale: Altered fetal cerebral blood flow results from cranial pressure during contractions, triggering vagal stimulation and early decelerations. This is the physiological response to head compression.

Choice D rationale: Umbilical cord compression causes variable decelerations due to transient blood flow obstruction, unrelated to cranial pressure or cerebral perfusion changes.

Correct Answer is A

Explanation

Choice A rationale
When the fetal head is at 3+ station, it means that the baby’s head has moved down the birth canal and is very close to the vaginal opening. At this stage, the nurse should observe for crowning, which is when the widest part of the baby’s head can be seen at the vaginal opening. This is a critical time during labor, and the nurse needs to be prepared for the delivery of the baby.
Choice B rationale
Applying fundal pressure is not recommended as it can cause complications such as uterine rupture, fetal distress, and maternal discomfort. It is also not necessary when the fetal head is at 3+ station as the baby is already moving down the birth canal.
Choice C rationale
Oxytocin is a hormone that can stimulate uterine contractions. However, it is not necessary to prepare to administer oxytocin when the fetal head is at 3+ station. At this stage, the mother’s body is already effectively progressing through labor.
Choice D rationale

Observing for the presence of a nuchal cord, which is when the umbilical cord is wrapped around the baby’s neck, is important throughout labor. However, it is not the primary action the nurse should take when the fetal head is at 3+ station.

A. Decreased vaginal discharge. B. Weight gain of 0.5 to 1.3 kg. C. Urinary retention. D. A surge of energy.

Correct Answer is D

Explanation

Choice A rationale
Vaginal discharge, or leukorrhea, often increases during pregnancy due to higher levels of estrogen and greater blood flow to the vaginal area. It does not typically decrease before labor.
Choice B rationale
Weight gain is expected during pregnancy, but a sudden gain of 0.5 to 1.3 kg is not a typical sign that labor is about to start.
Choice C rationale
Urinary retention is not a typical sign that labor is about to start. In fact, many women find that they need to urinate more frequently as labor approaches, due to increased pressure on the bladder.
Choice D rationale
A surge of energy, often called “nesting,” can be a sign that labor is about to start. Some women experience a burst of energy and the desire to prepare their home for the baby in the days or hours before labor begins.
