labor and delivery questions and answers Questions
Question 1 of 5
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?
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.
Question 2 of 5
A patient who is 8 cm dilated develops circumoral numbness and dizziness. What is the nurse’s priority intervention?
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.
Question 3 of 5
The labor and delivery nurse is caring for a 27-year-old primigravida with the following vaginal exam: 2 to 3 cm dilated/70% effaced/-2 station. For the last 2 hours the FHR tracing has displayed a Category I tracing and uterine contractions that are every 2 minutes. The contractions are strong to palpation and the patient is now 3/70%/-2. Which is the nurse’s next best action?
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.
Question 4 of 5
Which explains why infants who are delivered via cesarean section before the start of labor have more difficulty transitioning to extrauterine life?
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.
Question 5 of 5
Which criteria should be verified prior to vacuum or forceps use? Select all that apply.
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.
