What are late FHR decelerations caused by?
- A. Altered cerebral blood flow
- B. Umbilical cord compression
- C. Uteroplacental insufficiency
- D. Meconium fluid
Correct Answer: C
Rationale: The correct answer is C: Uteroplacental insufficiency. Late FHR decelerations are caused by decreased blood flow and oxygen delivery to the fetus due to impaired uteroplacental circulation. This can result from conditions like placental abruption or placental insufficiency. Altered cerebral blood flow (A) is more related to early decelerations. Umbilical cord compression (B) typically causes variable decelerations. Meconium fluid (D) can lead to fetal distress but is not the primary cause of late decelerations.

Transvaginal ultrasonography is often performed during the first trimester. What conditions may require this test? (Select all that apply.)
- A. Multifetal gestation
- B. Bicornuate uterus
- C. Presence and location of pregnancy
- D. Amniotic fluid volume
Correct Answer: C
Rationale: Transvaginal ultrasound is used to confirm fetal viability, assess multiple gestations, and check for uterine abnormalities.
A pregnant woman who is 28 weeks gestation reports that she feels dizzy and faint when she stands up. What should the nurse instruct the patient to do?
- A. Lie down flat on your back immediately.
- B. Stand up quickly to prevent dizziness from worsening.
- C. Drink a large amount of water to alleviate the dizziness.
- D. Get up slowly and avoid standing for long periods.
Correct Answer: D
Rationale: The correct answer is D, instructing the pregnant woman to get up slowly and avoid standing for long periods. This is because during pregnancy, blood pressure can drop when standing up quickly, leading to dizziness and fainting. Getting up slowly allows the body to adjust gradually, preventing a sudden drop in blood pressure. Standing for long periods can worsen these symptoms, so it is important to avoid prolonged standing.
A: Lying down flat on the back immediately can worsen symptoms in this case by reducing blood flow to the brain.
B: Standing up quickly can exacerbate dizziness and fainting by causing a sudden drop in blood pressure.
C: Drinking a large amount of water may not address the underlying issue of postural hypotension and could potentially worsen symptoms by increasing blood volume without addressing the drop in blood pressure.
How should the nurse respond to a concern about alcohol exposure during conception?
- A. Inform the doctor
- B. Reassure it's unlikely the baby was affected
- C. Suggest abortion
- D. Recommend ultrasound
Correct Answer: B
Rationale: Occasional alcohol exposure around conception is unlikely to cause significant harm, though ongoing abstinence is advised.
A nurse is caring for a laboring person who is experiencing strong contractions. What is the most important intervention to support the laboring person during this time?
- A. provide comfort measures
- B. assist with breathing exercises
- C. provide reassurance and comfort
- D. administer antibiotics
Correct Answer: A
Rationale: The correct answer is A: provide comfort measures. Comfort measures such as massage, positioning, and relaxation techniques help the laboring person cope with the pain and intensity of contractions. By providing comfort, the nurse can help reduce stress and anxiety, promoting a more positive labor experience.
Choice B (assist with breathing exercises) can be helpful, but comfort measures are more essential for overall well-being during labor. Choice C (provide reassurance and comfort) is similar to the correct answer but lacks the specific action of providing comfort measures. Choice D (administer antibiotics) is irrelevant to the management of strong contractions and is not indicated unless there is a specific medical reason for antibiotics.
What is the primary purpose of performing an episiotomy during delivery?
- A. to reduce the risk of perineal trauma
- B. to promote faster delivery
- C. to facilitate fetal descent
- D. to provide immediate fetal oxygenation
Correct Answer: A
Rationale: The primary purpose of performing an episiotomy during delivery is to reduce the risk of perineal trauma. Episiotomy is a surgical incision made in the perineum to widen the vaginal opening during childbirth, which can help prevent severe tearing of the perineal tissue. This procedure is performed to provide controlled and precise incision, reducing the likelihood of extensive tears that may lead to complications such as infection or prolonged healing time. It is not done to promote faster delivery, facilitate fetal descent, or provide immediate fetal oxygenation. These choices do not accurately reflect the main goal of episiotomy, which is to minimize perineal trauma.
