Anatomy and Physiology of Pregnancy Quizlet Questions
Question 1 of 5
A physician has just documented on a prenatal client. The nurse notices that the physician notes the presence of Goodell's sign. The nurse understands that this sign indicates which of the following?
Correct Answer: A
Rationale: The correct answer is A, changes in the cervix. Goodell's sign refers to the softening of the cervix that occurs during early pregnancy due to increased vascularity and hormonal changes. This sign is an important indicator of pregnancy and is typically observed during the first trimester. Choice B, changes in the uterus, is incorrect because Goodell's sign specifically refers to changes in the cervix, not the uterus as a whole. Choice C, passive movement of an unengaged fetus, is incorrect as Goodell's sign is not related to fetal movement. Choice D, fetus that has begun to descend and engage in the pelvis, is also incorrect as Goodell's sign occurs much earlier in pregnancy before the fetus engages in the pelvis.
Question 2 of 5
A client at 26 weeks gestation is in the office after being discharged from the hospital for preterm contractions. She states that she no longer is having contractions but is really having trouble with heartburn and reflux. Which is the nurse's best response?
Correct Answer: D
Rationale: The correct answer is D: Avoid foods that contain a lot of fat. This is the best response because fatty foods can worsen heartburn and reflux by relaxing the lower esophageal sphincter, leading to acid reflux. By avoiding high-fat foods, the client can reduce the likelihood of experiencing heartburn and reflux symptoms. Rationale: 1. High-fat foods can delay stomach emptying, causing food to stay longer in the stomach, increasing the risk of reflux. 2. Fatty foods can trigger the production of more stomach acid, exacerbating heartburn and reflux. 3. Avoiding high-fat foods can help decrease pressure on the stomach, reducing the likelihood of acid reflux. 4. Other options (A, B, C) do not address the root cause of heartburn and reflux associated with high-fat foods. In summary, choosing option D to avoid high-fat foods is the most appropriate response to help alleviate the client's heartburn and reflux symptoms during pregnancy.
Question 3 of 5
A young woman comes to the neighborhood clinic explaining that she had a negative urine pregnancy test last week but a positive test today. What is the best explanation?
Correct Answer: A
Rationale: The correct answer is A: It is probable that the hCG levels were not high enough to be detected last week. This is because hCG (human chorionic gonadotropin) is the hormone produced during pregnancy that is detected in pregnancy tests. In early pregnancy, hCG levels can be low and may not be detectable by a urine test until they reach a certain threshold. Therefore, a negative test last week could be due to the hCG levels being below the detection threshold at that time. A positive test today indicates that the hCG levels have increased and are now detectable. Summary of why the other choices are incorrect: B: It is likely that you may not be pregnant, so wait to see if you get your period. This is incorrect because a positive test indicates pregnancy, and waiting for a period may not be appropriate if the woman is indeed pregnant. C: Don't worry, this happens sometimes. You should perform another test in a few days. This
Question 4 of 5
A woman's obstetric history indicates that she is pregnant for the fourth time and all of her children from previous pregnancies are living. One was born at 39 weeks of gestation, twins were born at 34 weeks of gestation, and another child was born at 35 weeks of gestation. What is her gravidity and parity using the GTPAL system?
Correct Answer: B
Rationale: Rationale for Answer B (4-1-2-0-4): 1. Gravidity: Total number of pregnancies - She is pregnant for the 4th time (G=4). 2. Term Births: Number of pregnancies reaching 37 weeks or more - She had 1 term birth (T=1). 3. Preterm Births: Number of pregnancies ending between 20-36 weeks - She had twins born at 34 weeks (P=2). 4. Abortions: Number of pregnancies ending before 20 weeks - She has no reported abortions (A=0). 5. Living Children: Number of living children - She has all her children from previous pregnancies living (L=4). Summary of other choices: A: Incorrect because it indicates 3 term births, which is not accurate. C: Incorrect as it suggests 3 living children, which is not consistent with the scenario. D: Incorrect due to incorrect number of preterm births and living
Question 5 of 5
The nurse teaches a pregnant woman about the presumptive, probable, and positive signs of pregnancy. The woman demonstrates understanding of the nurse's instructions if she states that a positive sign of pregnancy is:
Correct Answer: B
Rationale: The correct answer is B: fetal movement palpated by the nurse-midwife. This is a positive sign of pregnancy because it is a direct indication of the presence of a fetus. Fetal movements can only be felt once the baby has developed enough to be physically palpable, typically around 18-20 weeks of gestation. This sign is considered reliable and conclusive evidence of pregnancy. A: A positive pregnancy test is a presumptive sign, as it indicates the possibility of pregnancy but is not definitive. C: Braxton Hicks contractions are probable signs, as they are common in pregnancy but do not confirm the presence of a fetus. D: Quickening, the mother's first perception of fetal movements, is a probable sign and does not provide definitive proof of pregnancy.
