A nurse is attending to a client who is a first-time mother, at term, and experiencing contractions. She is uncertain if she is in labor.Which of the following would the nurse identify as an indication of true labor?
Pattern of contractions.
Rupture of the membranes.
Position of the presenting part.
Changes in the cervix.
The Correct Answer is A
Choice A rationale
This is the correct answer. Regular, strong contractions with the presence of cervical change indicate that the woman is experiencing true labor.
Choice B rationale
Rupture of the membranes can occur before or during labor, but it is not a definitive sign of true labor.
Choice C rationale
The position of the presenting part is not a definitive sign of true labor.
Choice D rationale
Changes in the cervix can be a sign of true labor, but without regular, strong contractions, it is not a definitive sign.

Correct Answer is C
Explanation
Choice A rationale
A probable sign of pregnancy includes objective signs observed by an examiner, such as changes in the pelvic organs, enlargement of the abdomen, and positive pregnancy test.
Choice B rationale
Possible signs of pregnancy are those that are subjective and reported by the patient, such as nausea, vomiting, and missed period. These signs could be due to other conditions.
Choice C rationale
Feeling the baby moving, also known as quickening, is a presumptive sign of pregnancy. These are changes felt by the woman herself and can be caused by other conditions.
Choice D rationale
Positive signs of pregnancy are those that are confirmed by the examiner and cannot be caused by any other condition. These include hearing the fetal heartbeat, visualizing the fetus, and feeling the baby move.
Correct Answer is A
Explanation
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.
