When does the second stage of labor begin?

Correct Answer: D

Rationale: The correct answer is D: when pushing begins. The second stage of labor begins when the cervix is fully dilated, and the mother starts pushing to deliver the baby. This stage ends with the birth of the baby. Option A is incorrect because the second stage begins after birth. Option B is incorrect as it refers to the transition phase, not the second stage. Option C is incorrect because the cervix being fully dilated and effaced marks the beginning of the second stage, not the end of it.

Correct Answer: B

Rationale: During the third stage of labor, the correct answer is B because it describes the typical experiences of the birthing person during this stage. Cramping signifies uterine contractions, a gush of fresh vaginal bleeding indicates the delivery of the placenta, and lengthening of the umbilical cord indicates separation from the placenta. The other options are incorrect as they do not align with the physiological processes of the third stage of labor. A is incorrect as the fetus is delivered in the second stage, not the third. C is incorrect as dyspnea (difficulty breathing) is not a common symptom during the third stage. D is incorrect as increased blood pressure and pain are not typical experiences during this stage.

Correct Answer: B

Rationale: The correct answer is B. In the fourth stage of labor, the nurse should respect the rapid psychologic changes by taking the lead from the parents regarding interruption of bonding. This is important because it allows the parents to establish a strong bond with their newborn without feeling pressured or rushed. By following the parents' cues, the nurse can support their emotional needs and facilitate a positive bonding experience. Choices A, C, and D are incorrect because they do not prioritize the parents' emotional needs and may disrupt the bonding process. Inviting the family to see the newborn (Choice A) may add stress to the situation. Asking multiple questions about taking pictures (Choice C) may be intrusive. Taking the newborn to the nursery (Choice D) may interfere with the bonding process and discourage parental involvement.

Correct Answer: B

Rationale: The correct answer is B because having multiple family members in the room during labor can be overwhelming and hinder the progress of labor. It is important for the laboring person to have privacy, focus, and reduce stress for a smoother labor experience. Asking the family members to leave the room ensures a calm and supportive environment for the laboring person. Incorrect Choices: A: Educating the family about pain normalcy is helpful, but privacy and focus are more crucial during labor. C: Mentioning epidural may not be appropriate as it is the laboring person's decision and may not be the best option for everyone. D: Assuming the laboring person wants family in the room without considering their preference may not be the best approach for their comfort and progress in labor.

Correct Answer: D

Rationale: The correct answer is D because maternal-fetal exchange of oxygen and waste products continues during uterine contractions unless placental functions are reduced. Contractions do not directly affect this exchange, so option A is incorrect. Option B is incorrect because blood pressure changes do not necessarily impact the exchange. Option C is incorrect because spiral arteries play a role in supplying blood to the placenta, but compression during contractions does not halt the exchange process.
