Arrange the seven cardinal movements of labor, in order.
- A. Descent
- B. Expulsion
- C. Extension
- D. External rotation
Correct Answer: A
Rationale: The correct order of cardinal movements of labor is:
1. Engagement
2. Descent
3. Flexion
4. Internal rotation
5. Extension
6. Restitution
7. External rotation
Engagement occurs first as the fetal presenting part enters the maternal pelvis. Descent is the second cardinal movement, where the fetus moves down the birth canal. Flexion follows, allowing the smallest diameter of the fetal head to present. Internal rotation positions the fetus for delivery. Extension occurs next, facilitating the passage of the head through the birth canal. Restitution aligns the fetal head with the shoulders. External rotation allows the shoulders to rotate for delivery. Therefore, Descent is the correct first cardinal movement in the sequence. Other choices like Expulsion, Extension, and External rotation occur later in the process and are not in the correct order.

A patient who is 8 cm dilated develops circumoral numbness and dizziness. What is the nurse’s priority intervention?
- A. Call the health care provider immediately.
- B. Increase intravenous fluid, as these are signs of hypovolemia.
- C. Have the patient slow down her breathing.
- D. Have her start pushing, as these are signs of the beginning of the second stage.
Correct Answer: C
Rationale: The correct answer is C: Have the patient slow down her breathing. Circumoral numbness and dizziness are signs of hyperventilation, which can occur due to rapid breathing during labor. Slowing down the patient's breathing helps prevent respiratory alkalosis and promotes proper oxygenation for both the mother and the baby. Calling the health care provider immediately (A) may cause a delay in addressing the immediate issue. Increasing IV fluids (B) may not address the root cause of the symptoms. Having her start pushing (D) prematurely can be harmful if she is not fully dilated.
A fetus is positioned in a longitudinal lie with its head in the fundus with both hips and knees flexed. Which presentation is this known as?
- A. Frank breech
- B. Complete breech
- C. Vertex
- D. Transverse
Correct Answer: B
Rationale: The correct answer is B: Complete breech. In this presentation, the fetus is positioned with hips and knees flexed, and the head is in the fundus. This is different from a Frank breech where the hips are flexed but the knees are extended. Vertex presentation refers to the head being down and Transverse presentation is when the fetus is lying horizontally. In this case, the description matches the characteristics of a complete breech presentation, making it the correct answer.
The primary difference between the labor of a nullipara and that of a multipara is
- A. total duration of labor.
- B. level of pain experience
- C. amount of cervical dilation.
- D. sequence of labor mechanisms.
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.
What anticipatory guidance should the nurse provide for new parents regarding sociologic changes?
- A. Explain that roles will not change at home
- B. Explain that stresses will be over now that the newborn is born.
- C. Tell the parents not to stress over household changes.
- D. Prepare them for possible strains on relationships.
Correct Answer: D
Rationale: The correct answer is D because it addresses the potential strains on relationships that can occur after the birth of a child. New parents often experience changes in their relationship dynamics due to increased responsibilities, sleep deprivation, and shifts in priorities. By preparing them for these possible strains, the nurse can help them navigate these challenges effectively.
A is incorrect because roles often do change at home with the arrival of a newborn. B is incorrect as stresses can actually increase after the baby is born. C is incorrect as it dismisses the importance of addressing household changes and potential stressors.
Pregnant patients can usually tolerate the normal blood loss associated with childbirth because of which physiologic adaptation to pregnancy?
- A. A higher hematocrit
- B. Increased leukocytes
- C. Increased blood volume
- D. A lower fibrinogen level
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.
