Maternal Newborn ATI Proctored Exam
1. A client at 32 weeks of gestation with placenta previa is actively bleeding. Which medication should the provider likely prescribe?
- A. Betamethasone
- B. Indomethacin
- C. Nifedipine
- D. Methylergonovine
Correct answer: A
Rationale: In cases of placenta previa with active bleeding at 32 weeks of gestation, Betamethasone is prescribed to accelerate fetal lung maturity in anticipation of potential preterm delivery. This medication helps in reducing the risk of respiratory distress syndrome in the newborn, which is crucial in managing such high-risk pregnancies. Indomethacin is a nonsteroidal anti-inflammatory drug not indicated in this scenario and may be contraindicated due to its effects on platelet function and potential risk of bleeding. Nifedipine is a calcium channel blocker used for conditions like preterm labor or hypertension, not specifically for placenta previa with active bleeding. Methylergonovine is a uterotonic drug used to prevent or control postpartum hemorrhage, not indicated for placenta previa with active bleeding.
2. A client is scheduled for a maternal serum alpha-fetoprotein test at 15 weeks of gestation. The client asks the nurse about the purpose of this test. What explanation should the nurse provide?
- A. This test screens for neural tube defects and other developmental abnormalities in the fetus.
- B. It assesses various markers of fetal well-being.
- C. This test identifies an Rh incompatibility between the mother and fetus.
- D. It is a screening test for spinal defects in the fetus.
Correct answer: A
Rationale: The maternal serum alpha-fetoprotein (MSAFP) test is performed around 15-18 weeks of gestation to screen for neural tube defects and other developmental abnormalities in the fetus, not to assess fetal lung maturity, markers of fetal well-being, or Rh incompatibility between the mother and fetus. Choice A is the correct answer as it accurately reflects the purpose of the MSAFP test. Choices B, C, and D are incorrect because they do not align with the primary goal of this screening test.
3. An adolescent is being taught about levonorgestrel contraception by a school nurse. What information should the nurse include in the teaching?
- A. You should take the medication within 72 hours following unprotected sexual intercourse.
- B. Do not take this medication if you are on an oral contraceptive.
- C. If you do not start your period within 5 days of taking this medication, you will need a pregnancy test.
- D. One dose of this medication will prevent pregnancy for 14 days after taking it.
Correct answer: A
Rationale: Levonorgestrel is an emergency contraceptive that works by inhibiting ovulation to prevent conception. It is most effective when taken as soon as possible within 72 hours following unprotected sexual intercourse. Therefore, the nurse should instruct the adolescent to take the medication promptly to maximize its effectiveness. Choice B is incorrect because levonorgestrel can be used even if the individual is on oral contraceptives. Choice C is incorrect as the efficacy of levonorgestrel is not determined by the onset of menstruation. Choice D is incorrect because levonorgestrel is a single-dose emergency contraceptive and does not provide protection for 14 days after ingestion.
4. A client is in labor and reports increasing rectal pressure. She is experiencing contractions 2 to 3 minutes apart, each lasting 80 to 90 seconds, and a vaginal examination reveals that her cervix is dilated to 9 cm. The client is in which of the following phases of labor?
- A. Active
- B. Transition
- C. Latent
- D. Descent
Correct answer: B
Rationale: The client is in the transition phase of labor, characterized by cervical dilatation of 8 to 10 cm and contractions every 2 to 3 minutes, each lasting 45 to 90 seconds. In this phase, the cervix is nearly fully dilated, preparing the client for the pushing stage. The active phase of labor typically involves cervical dilatation from 4 to 7 cm, whereas the latent phase is the early phase of labor when the cervix dilates from 0 to 3 cm. Descent is not a phase of labor but rather refers to the movement of the fetus through the birth canal during the second stage of labor.
5. During a nonstress test for a pregnant client, a nurse uses an acoustic vibration device. The client inquires about its purpose. Which response should the nurse provide?
- A. It is used to stimulate uterine contractions.
- B. It will decrease the incidence of uterine contractions.
- C. It lulls the fetus to sleep.
- D. It awakens a sleeping fetus.
Correct answer: D
Rationale: The acoustic vibration device is utilized during a nonstress test to awaken a sleeping fetus. This action helps ensure more accurate test results by eliciting fetal movements and heart rate accelerations, which are indicators of fetal well-being. Choices A, B, and C are incorrect because the primary purpose of the acoustic vibration device during a nonstress test is not to stimulate uterine contractions, decrease uterine contractions, or lull the fetus to sleep. Instead, it is specifically used to awaken a sleeping fetus to assess fetal well-being.
