Fetal Development Questions Questions
Question 1 of 5
What is the purpose of chorionic villus sampling (CVS) in the first trimester?
Correct Answer: C
Rationale: Rationale: CVS is done in the first trimester to assess the risk of chromosomal abnormalities in the fetus by obtaining a sample of cells from the placenta. This allows for genetic testing to detect conditions such as Down syndrome. Other choices are incorrect as CVS is not used to measure amniotic fluid quantity (A), confirm pregnancy (B), or assess maternal infection (D).
Question 2 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 3 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 4 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.
Question 5 of 5
The nurse is providing education to a pregnant person regarding the nausea and vomiting of pregnancy. Identify the relief measures the nurse would discuss. Select all that apply.
Correct Answer: A
Rationale: The correct answer is A: avoid dairy products. This is because dairy products can exacerbate nausea in some pregnant individuals due to their high fat content. Avoiding dairy products can help reduce nausea symptoms. Rationale: 1. Avoiding dairy products: High fat content in dairy products can trigger nausea in some pregnant individuals. 2. Avoid strong odors: While strong odors can trigger nausea, it is not a specific relief measure for nausea and vomiting of pregnancy. 3. Drink fluids between meals: Staying hydrated is important, but drinking fluids between meals is not a specific relief measure for nausea and vomiting of pregnancy. 4. Drink sweet fluids: While some pregnant individuals find relief from nausea by consuming sweet fluids, it is not a universal recommendation and may not work for everyone.
