Scenario: A 26-year-old pregnant woman at 26 weeks gestation is scheduled for a glucose screening test. She expresses concerns about the procedure and asks the nurse why this test is necessary.   Question: Which of the following is the most important reason for performing glucose screening between 24 and 28 weeks of pregnancy?

Scenario: A 36-year-old pregnant woman at 38 weeks gestation is being monitored in labor. The fetal heart rate (FHR) tracing shows late decelerations following contractions. The nurse notes that the patient’s blood pressure is 90/60 mmHg, and the woman is lying flat on her back.   Question: What is the most appropriate nursing intervention to address the late decelerations and maternal hypotension in this patient?

Scenario: A 34-year-old woman, G2P1, is in the first stage of labor. She is experiencing discomfort with contractions but has been lying on her back for the past hour. The nurse encourages her to change positions to help relieve discomfort and improve labor progress.   Question: Why is it important for the nurse to encourage the patient to change positions during the first stage of labor?

Scenario: A 28-year-old woman, G1P0, is in labor with a favorable gynecoid pelvis. She is dilated to 5 cm and having regular contractions. The healthcare team anticipates a vaginal delivery due to the favorable shape of her pelvis.   Question: Which of the following best explains why the gynecoid pelvis shape is favorable for vaginal birth?

Scenario: A 32-year-old pregnant woman, at 28 weeks gestation, presents for her routine prenatal visit. She has a history of hypertension, which has been poorly controlled despite treatment. During the examination, her blood pressure is measured at 160/100 mmHg. The nurse is concerned about the potential impact of her blood pressure on the developing fetus.   Question: Given the patient’s elevated blood pressure, which of the following is the most important concern related to placental perfusion and fetal growth?
