When evaluating the patient's progress, the nurse knows that four of the five fetal factors that interact to regulate the heart Nrate Rare I(SeGlect Bal.l CthatM apply.) U S N T O
- A. baroreceptors.
- B. adrenal glands.
- C. chemoreceptors.
- D. uterine activity.
Correct Answer: A
Rationale: The correct answer is A: baroreceptors. Baroreceptors are sensory receptors that detect changes in blood pressure and play a role in regulating heart rate. They are one of the fetal factors that interact to regulate heart rate. Adrenal glands (B) primarily regulate stress response, chemoreceptors (C) detect changes in oxygen and carbon dioxide levels, and uterine activity (D) refers to contractions during labor, which are not directly related to regulating fetal heart rate. Thus, A is correct as it directly influences heart rate regulation.

Multiple gestation can lead to what labor complication?
- A. tachysystole
- B. postterm birth
- C. postterm birth
- D. early declarations
Correct Answer: C
Rationale: The correct answer is C: postterm birth. Multiple gestation, such as twins or triplets, often leads to a higher risk of postterm birth due to the increased likelihood of preterm labor and delivery. This is because the uterus may become overdistended and unable to maintain the pregnancy to full term, resulting in postterm birth.
Incorrect choices:
A: Tachysystole is excessive uterine contractions, which is not directly related to multiple gestation.
B: Postterm birth is already covered as the correct answer.
D: Early decelerations are a common finding in labor but not specifically associated with multiple gestation complications.
What is one potential fetal complication of using the vacuum extractor?
- A. cephalohematoma
- B. face presentation
- C. fetal growth restriction
- D. scalp fracture
Correct Answer: A
Rationale: The correct answer is A: cephalohematoma. When using a vacuum extractor during childbirth, the device applies suction to the baby's head to assist with delivery. This suction can cause a collection of blood between the baby's skull and periosteum, resulting in a cephalohematoma. This complication is due to the pressure exerted on the baby's head during the extraction process. Cephalohematoma is a common side effect of vacuum extraction and typically resolves on its own. Face presentation and fetal growth restriction are not directly related to the use of a vacuum extractor. Scalp fracture is a rare but serious complication that can occur if excessive force is applied during vacuum extraction, leading to bone injury, which is different from the collection of blood in a cephalohematoma.
What pregnant person is at high risk for labor dystocia?
- A. 38-week gestation
- B. 41-year-old
- C. prenatal anemia
- D. no prenatal care
Correct Answer: B
Rationale: The correct answer is B: 41-year-old. Advanced maternal age increases the risk of labor dystocia due to reduced uterine muscle tone and coordination. Older individuals are more likely to experience prolonged labor or difficulty with fetal descent. Choice A (38-week gestation) is not a risk factor for labor dystocia. Prenatal anemia (Choice C) may lead to complications during pregnancy but is not directly linked to labor dystocia. Lack of prenatal care (Choice D) can increase the risk of complications but is not a specific risk factor for labor dystocia.
What is the condition in which the umbilical cord vessels branch prior to insertion into the placenta?
- A. placenta previa
- B. placenta cervix
- C. velamentous insertion
- D. vasa previa
Correct Answer: C
Rationale: The correct answer is C: velamentous insertion. In this condition, the umbilical cord vessels branch before reaching the placenta, making them vulnerable to compression and rupture. Placenta previa (A) refers to the placenta covering the cervix, not cord insertion. Placenta cervix (B) is not a recognized term. Vasa previa (D) is when fetal vessels traverse the fetal membranes overlying the cervix, not related to branching of umbilical cord vessels before insertion into the placenta.
A nurse is taking a birth history assessment on a client who is 8 weeks gestation and has one child who was born at 38 weeks. Which is consistent with this birth history?
- A. Primipara
- B. Primigravida
- C. Nulligravida
- D. Multipara
Correct Answer: D
Rationale: The correct answer is D: Multipara. This term refers to a woman who has given birth to two or more children. In this case, the client has one child already, making her a multipara.
A: Primipara refers to a woman who has given birth to one child, which does not match the client's birth history.
B: Primigravida refers to a woman who is pregnant for the first time, which also does not match the client's history.
C: Nulligravida refers to a woman who has never been pregnant, which is not the case for the client.
Therefore, the correct term to describe the client's birth history is Multipara, as she has one child and is currently 8 weeks gestation.
