labor and delivery questions and answers Questions
Question 1 of 5
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 suffer from depression due to lack of emotional and physical support. This is supported by research showing the positive impact of labor support on maternal mental health and birth outcomes. Choice A is incorrect as labor support can also be provided by healthcare professionals. Choice B is incorrect as laboring patients benefit from emotional and physical support during childbirth. Choice C is incorrect as pandemic requirements did impact birth outcomes, especially for patients who lacked support.
Question 2 of 5
Pregnant patients can usually tolerate the normal blood loss associated with childbirth because of which physiologic adaptation to pregnancy?
Correct Answer: C
Rationale: The correct answer is C: Increased blood volume. During pregnancy, blood volume increases by about 40-50% 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 during delivery. A higher hematocrit (choice A) could indicate dehydration, not increased blood volume. Increased leukocytes (choice B) are related to the immune response, not blood loss tolerance. A lower fibrinogen level (choice D) could lead to increased bleeding risk, not tolerance to blood loss.
Question 3 of 5
Which factor ensures that the smallest anterior-posterior diameter of the fetal head enters the pelvis?
Correct Answer: B
Rationale: Flexion is the correct answer. During labor, fetal head flexion allows the smallest anterior-posterior diameter of the head to enter the pelvis first, reducing the risk of cephalopelvic disproportion. Station refers to the level of the presenting part in the maternal pelvis, not the head orientation. Descent is the downward movement of the fetus in the birth canal, not related to head position. Engagement occurs when the widest part of the presenting part reaches the level of the maternal ischial spines, not specifically related to the orientation of the fetal head.
Question 4 of 5
The nurse is assessing a patient in the active phase of labor. What should the nurse expect during this phase?
Correct Answer: C
Rationale: During the active phase of labor, contractions become stronger and more frequent, leading to cervical dilation. This is when the patient typically experiences the urge to push as the cervix reaches around 7-10 cm dilation. This signifies progress towards the second stage of labor. Choices A, B, and D are incorrect as they do not specifically align with the characteristics of the active phase of labor. A patient may exhibit a range of emotions and behaviors during labor, but the key indicator of the active phase is the urge to push due to cervical dilation.
Question 5 of 5
The primary difference between the labor of a nullipara and that of a multipara is
Correct Answer: A
Rationale: The correct answer is A: total duration of labor. This is because nulliparas (women who have never given birth before) generally have longer labors compared to multiparas (women who have given birth before). This is due to factors such as the first-time stretching of the birth canal and the body's learning process. The level of pain experience (B) can vary among individuals and is not a primary difference between nulliparas and multiparas. The amount of cervical dilation (C) can be influenced by various factors and is not a defining difference between the two groups. The sequence of labor mechanisms (D) is a universal process in labor and does not differ based on whether a woman is a nullipara or multipara.
