ATI Maternal Newborn Proctored Exam 2023
1. A newborn is born to a mother with poorly controlled type 2 diabetes. The newborn is macrosomic and presents with respiratory distress syndrome. The most likely cause of the respiratory distress is which of the following?
- A. Hyperinsulinemia
- B. Increased deposits of fat in the chest and shoulder area
- C. Brachial plexus injury
- D. Increased blood viscosity
Correct answer: A
Rationale: The correct answer is hyperinsulinemia. In infants born to mothers with poorly controlled diabetes, the excess glucose crosses the placenta, leading to fetal hyperglycemia. This results in fetal hyperinsulinemia, which in turn can cause macrosomia (large birth weight), increasing the risk of respiratory distress syndrome due to the immature lungs' inability to handle the increased workload. Hyperinsulinemia, not increased deposits of fat, brachial plexus injury, or increased blood viscosity, is the most likely cause of respiratory distress in this scenario.
2. A healthcare professional is reviewing the laboratory values of a client who has respiratory acidosis. Which of the following findings should the healthcare professional expect?
- A. HCO3- 30 mEq/L
- B. PaCO2 50 mm Hg
- C. pH 7.45
- D. Potassium 3.3 mEq/L
Correct answer: B
Rationale: In respiratory acidosis, the primary disturbance is an increase in PaCO2 levels above the normal range of 35-45 mm Hg. Option B, PaCO2 50 mm Hg, indicates an elevated partial pressure of carbon dioxide, which is consistent with respiratory acidosis. Options A, C, and D are not directly indicative of respiratory acidosis. HCO3- (Option A) is more related to metabolic acidosis or alkalosis, pH (Option C) is within the normal range indicating no acid-base imbalance, and potassium (Option D) levels are not specific to respiratory acidosis.
3. A client who was admitted to the maternity unit at 38 weeks of gestation and who is experiencing polyhydramnios is found to have which of the following?
- A. The client is carrying more than one fetus
- B. There is an elevated level of alpha-fetoprotein (AFP) in the amniotic fluid
- C. An excessive amount of amniotic fluid is present
- D. The fetus is likely to have a congenital anomaly, be growth restricted, or demonstrate fetal distress during labor
Correct answer: C
Rationale: Polyhydramnios refers to the presence of an excessive amount of amniotic fluid around the fetus. This condition can result from various causes, such as maternal diabetes, fetal anomalies, or genetic disorders. It can lead to complications during pregnancy and delivery, such as preterm labor, placental abruption, or fetal malpresentation. Understanding this diagnosis is crucial for providing appropriate care and monitoring to ensure the best outcomes for both the mother and the fetus.
4. A client at 37 weeks of gestation with placenta previa asks the nurse why the provider does not do an internal examination. Which of the following explanations of the primary reason should the nurse provide?
- A. There is an increased risk of introducing infection.
- B. This could initiate preterm labor.
- C. This could result in profound bleeding.
- D. There is an increased risk of rupture of the membranes.
Correct answer: C
Rationale: Performing an internal examination in a client with placenta previa can lead to significant bleeding due to the proximity of the placenta to the cervical os. This bleeding can be severe and potentially life-threatening. Therefore, it is crucial to avoid any unnecessary manipulation that could disrupt the delicate balance and lead to hemorrhage.
5. A client who is 4 hours postpartum following a vaginal delivery is being assessed by a nurse. Which of the following findings should the nurse identify as the priority?
- A. Saturated perineal pad in 30 minutes
- B. Deep tendon reflexes 4+
- C. Fundus at the level of the umbilicus
- D. Approximated edges of episiotomy
Correct answer: A
Rationale: In a client who is 4 hours postpartum, a saturated perineal pad within 30 minutes is a priority finding as it may indicate excessive postpartum bleeding (hemorrhage), which requires immediate intervention to prevent further complications such as hypovolemic shock. Deep tendon reflexes being 4+ is within normal limits postpartum. The fundus at the level of the umbilicus is an expected finding at this time frame, indicating proper involution of the uterus. Approximated edges of an episiotomy suggest proper healing.
