Arrange the seven cardinal movements of labor, in order.

Correct Answer: A

Rationale: The correct order of the seven cardinal movements of labor is: Descent, Flexion, Internal Rotation, Extension, Restitution, External Rotation, and Expulsion. Descent is the first cardinal movement, as the baby moves down the birth canal. Flexion follows to allow the baby's head to pass through the pelvis. Internal Rotation, Extension, and Restitution then occur to facilitate the baby's shoulders and body turning in alignment with the mother's pelvis. External Rotation follows to help the shoulders rotate to the correct position for delivery. Finally, Expulsion is when the baby is born. This sequence ensures a smooth and safe delivery. The other choices are incorrect as they are not part of the specific sequence of cardinal movements during labor.

Correct Answer: D

Rationale: The correct answer is D, documenting the findings. In this scenario, the patient is in active labor with regular strong contractions, cervical change, and a reassuring fetal heart rate tracing. The priority is to document these important clinical findings accurately for proper assessment and monitoring of progress. Encouraging ambulation (A) may not be safe due to the frequency and strength of contractions. Initiating oxytocin (B) is unnecessary as labor is progressing well on its own. Assisting the patient to a warm bath (C) may provide comfort but is not the most critical action at this time.

Correct Answer: D

Rationale: The correct answer is D because infants delivered via cesarean section before labor may not have had the opportunity to expel amniotic fluid from their lungs through the vaginal passage, leading to respiratory distress. This residual fluid can hinder the initiation of spontaneous respirations, causing difficulty in transitioning to extrauterine life. Choices A, B, and C are incorrect because hyperthermia from warm IV fluids, respiratory depression from regional anesthesia, and reduced placental blood flow from maternal position are not primary factors affecting the infant's ability to transition to extrauterine life in this scenario.

Correct Answer: B

Rationale: The correct answer is B: The fetus must be at least 34 weeks gestation. This is because using vacuum or forceps delivery before 34 weeks gestation can increase the risk of complications for both the mother and the baby. For the other choices: A: The woman’s bladder being empty is not a specific criteria for vacuum or forceps use. C: A Category I tracing is related to fetal heart monitoring and does not directly impact the decision to use vacuum or forceps. D: While it is ideal for the cervix to be completely dilated before vacuum or forceps use, it is not the primary criteria to be verified.

Correct Answer: C

Rationale: The correct answer is C because the multigravida uterus has undergone labor before, making muscle coordination more efficient. This allows for faster and more coordinated contractions, leading to precipitous labor. Choice A is incorrect because the cervix does not weaken after each delivery. Choice B is incorrect as simultaneous dilation and effacement are not specific to multiparous women. Choice D is incorrect because the ability to recognize labor onset is not a determining factor in the occurrence of precipitous labor.
