Fetal Development Questions Questions
Question 1 of 5
A 37-year-old patient is being seen for her first OB appointment after having a positive pregnancy test at home. She thinks she is about 6 weeks pregnant. She and her husband have been trying to conceive for 7 years, and she has a history of three spontaneous abortions. What antepartum testing do you anticipate the provider ordering at today’s visit?
Correct Answer: A
Rationale: The correct answer is A: a vaginal ultrasound to confirm gestation age, due date, and pregnancy viability. At the first OB appointment, confirming gestational age and viability is crucial, especially for a patient with a history of spontaneous abortions. This ultrasound will help determine the accurate due date and assess the viability of the pregnancy. Maternal assay blood tests for genetic and chromosomal disorders (choice B) are usually done later in the pregnancy, around 10-13 weeks. Nuchal translucency ultrasound (choice C) and integrated screen blood test (choice D) are typically done between 11-14 weeks and are not usually ordered at the first OB appointment.
Question 2 of 5
A 27-year-old patient presents with injuries sustained in a motor vehicle accident. She was wearing her seatbelt and has multiple bruises and scrapes along her abdomen. She complains of pain 3/10 in her abdomen. She is G1P0 and is at 14 weeks’ gestation. A bedside ultrasound scan confirms that the fetus is stable and not in any distress. The patient is Rh negative, and her husband is Rh positive. What do you anticipate being the next step?
Correct Answer: B
Rationale: The correct answer is B: Administer Rh(D) immune globulin (RhoGAM). In this scenario, the patient is Rh negative and her husband is Rh positive, which puts her at risk for Rh isoimmunization. Administration of Rh(D) immune globulin (RhoGAM) helps prevent the mother's immune system from developing antibodies against the Rh-positive fetus's blood, thereby protecting future pregnancies. This intervention is crucial in preventing hemolytic disease of the newborn. Choice A: Obtaining a urinalysis is not indicated in this case as the patient's main concern is her abdominal pain and pregnancy status, not related to her urinalysis. Choice C: Discharging the patient without administering Rh(D) immune globulin would be inappropriate as it puts future pregnancies at risk of complications due to Rh incompatibility. Choice D: Scheduling a follow-up ultrasound is not the immediate next step. Administering Rh(D) immune globulin is the priority to
Question 3 of 5
The nurse is reviewing the schedule for the OB/GYN she works for. In reviewing a patient’s chart, the nurse notes the patient is 32 weeks pregnant, has hypertension, and had a previous fetal death. What test does the nurse anticipate the provider will order?
Correct Answer: C
Rationale: The correct answer is C: nonstress test. A nonstress test is used to assess fetal well-being by monitoring the baby's heart rate in response to its own movements. In this case, the patient's history of hypertension and previous fetal death indicate a higher risk pregnancy, making it important to monitor the baby's well-being. A contraction stress test (choice A) is not suitable for a patient with hypertension as it can induce contractions and potentially harm the baby. An amniotic fluid index (choice B) is used to evaluate amniotic fluid levels and is not specific to this patient's situation. Fetal movement count (choice D) assesses the baby's movements but does not provide real-time information on fetal well-being like a nonstress test does.
Question 4 of 5
The nurse is auscultating the fetal heart rate (FHR) on a patient at 37 weeks’ gestation. The nurse notes a line of darkened pigmentation on the pregnant person’s abdomen starting at the symphysis pubis and ending at the sternum. How does the nurse document this finding?
Correct Answer: B
Rationale: The correct answer is B: linea nigra. The linea nigra is a darkened pigmented line that runs from the symphysis pubis to the sternum in pregnant individuals. This line is a normal finding in pregnancy due to hormonal changes. It is important for the nurse to document this finding accurately as it is a common physiological change. Rationale: 1. Cholasma (A) is also known as the mask of pregnancy, presenting as dark patches on the face. 2. Spider nevi (C) are small, dilated blood vessels on the skin, not related to the linea nigra. 3. Striae gravidarum (D) are stretch marks that occur due to rapid stretching of the skin during pregnancy, not related to the pigmented line. In summary, the correct answer is B because the darkened line described is characteristic of linea nigra, a common finding in pregnancy, while the other choices are unrelated to this specific observation.
Question 5 of 5
The nurse is providing care to a pregnant person at 32 weeks’ gestation. The nurse expects to observe what change in the pregnant person’s spine?
Correct Answer: D
Rationale: The correct answer is D: lordosis. At 32 weeks' gestation, the pregnant person's center of gravity shifts forward, causing an increased lumbar lordosis to compensate. This change helps maintain balance and support the growing uterus. Sclerosis (choice A) refers to hardening of tissues, not a typical change in the spine during pregnancy. Scoliosis (choice B) is a lateral curvature of the spine, not typically related to pregnancy. Kyphosis (choice C) is an exaggerated outward curve in the upper spine, not a common change in pregnancy.
