During the COVID-19 pandemic, what was revealed about the importance of labor support?

Correct Answer: D

Rationale: The correct answer is D because patients who experienced a support ban during the pandemic were more likely to experience depression due to the lack of emotional and physical support during labor. This is supported by research showing the negative impact of isolation on mental health. Choices A and B are incorrect as labor support can come from various sources, not just the significant other, and patients benefit from support during labor. Choice C is incorrect as pandemic requirements did impact birth outcomes, such as increased stress and anxiety levels.

Correct Answer: C

Rationale: The correct answer is C: Increased blood volume. During pregnancy, a woman's blood volume increases by about 30-50% to support the growing fetus and prepare for potential blood loss during childbirth. This increased blood volume helps pregnant patients tolerate the normal blood loss associated with childbirth without experiencing severe complications like hypovolemic shock. Rationale: A: A higher hematocrit would not directly contribute to increased blood volume and would not help in tolerating blood loss during childbirth. B: Increased leukocytes are part of the immune response and are not directly related to blood volume or tolerance to blood loss. D: A lower fibrinogen level would not directly contribute to increased blood volume and would not help in tolerating blood loss during childbirth. Summary: Choice C is correct because increased blood volume is a crucial physiologic adaptation during pregnancy that enables pregnant patients to tolerate the normal blood loss associated with childbirth. Choices A, B, and D are incorrect as they are not directly related to this

Correct Answer: B

Rationale: The correct answer is B: Flexion. Flexion of the fetal head is crucial for the smallest anterior-posterior diameter to enter the pelvis first. This position optimizes the fit of the fetal head through the maternal pelvis, reducing the risk of complications during labor. Station (A) refers to the level of the presenting part in the pelvis, descent (C) is the downward movement of the fetus, and engagement (D) is when the widest diameter of the fetal head passes through the maternal pelvic inlet. However, these factors do not specifically address the orientation of the fetal head to ensure the smallest diameter enters the pelvis.

Correct Answer: C

Rationale: The correct answer is C because during the active phase of labor, the cervix dilates from 4 to 7 centimeters, and the patient typically experiences the urge to push as the baby descends further down the birth canal. This indicates progress in labor and readiness for the second stage. Choices A, B, and D are incorrect as they do not specifically align with the characteristics of the active phase of labor. Choice A is not necessarily indicative of the active phase, choice B may happen at any stage of labor, and choice D is more characteristic of transition phase rather than the active phase.

Correct Answer: A

Rationale: The correct answer is A: total duration of labor. Nullipara refers to a woman giving birth for the first time, while multipara refers to a woman who has given birth multiple times. The primary difference between their labors is the total duration. Nulliparas typically have longer labors due to the body's first experience with childbirth. The other choices (B, C, D) are not the primary difference between nullipara and multipara labors. Pain experience, cervical dilation, and labor mechanisms can vary based on individual factors, but the key distinction lies in the overall duration of labor based on parity.
