Anatomy and Physiology of Pregnancy Quizlet Questions
Question 1 of 5
Numerous changes in the integumentary system occur during pregnancy. Which change persists after birth?
Correct Answer: D
Rationale: The correct answer is D, Striae gravidarum, because it refers to stretch marks that occur during pregnancy and often persist postpartum. Epulis (A) is a benign gingival tumor that typically resolves after pregnancy. Chloasma (B) is a skin condition causing dark patches that usually fade postpartum. Telangiectasia (C) are small dilated blood vessels that commonly appear during pregnancy but may diminish after giving birth. Therefore, the key differentiator is the persistence of Striae gravidarum after delivery.
Question 2 of 5
The nurse caring for the pregnant patient must understand that the hormone essential for maintaining pregnancy is:
Correct Answer: D
Rationale: The correct answer is D: progesterone. Progesterone is essential for maintaining pregnancy as it helps in thickening the uterine lining to support implantation and fetal development. Estrogen (choice A) plays a role in preparing the uterus for implantation but is not the primary hormone for maintaining pregnancy. Human chorionic gonadotropin (hCG) (choice B) is produced by the placenta and helps in detecting pregnancy but does not maintain it. Oxytocin (choice C) is involved in labor and breastfeeding, not in maintaining pregnancy.
Question 3 of 5
Appendicitis may be difficult to diagnose in pregnancy because the appendix is:
Correct Answer: D
Rationale: The correct answer is D because during pregnancy, the enlarging uterus pushes the appendix downward and laterally, making it low and to the right. This displacement can lead to atypical presentation of appendicitis symptoms. Choices A and B are incorrect as the appendix is not displaced high and to either side. Choice C is incorrect as the McBurney point is a specific location for appendicitis pain but does not describe the actual position of the appendix during pregnancy.
Question 4 of 5
Which time-based description of a stage of development in pregnancy is accurate?
Correct Answer: B
Rationale: The correct answer is B: Full Term-Pregnancy from the beginning of week 39 of gestation to the end of week 40. This is accurate because full-term pregnancy typically ranges from 39 to 40 weeks of gestation, which is considered the optimal time for a baby to be born in terms of development and health. Viability (Choice A) refers to the ability of a fetus to survive outside the womb and typically occurs between 22 to 37 weeks. Preterm (Choice C) describes a pregnancy that occurs before 37 weeks. Postdate (Choice D) refers to a pregnancy that extends beyond 40 weeks. Therefore, Choices A, C, and D are incorrect as they do not accurately describe the full-term stage of pregnancy.
Question 5 of 5
To reassure and educate pregnant patients about changes in the uterus, nurses should be aware that:
Correct Answer: B
Rationale: The correct answer is B. Increased urinary frequency in the first trimester is due to exaggerated uterine anteflexion caused by softening. This is because the growing uterus exerts pressure on the bladder, leading to the need for more frequent urination. This is a common physiological change in early pregnancy due to the hormonal effects on the pelvic floor muscles and bladder capacity. A: Lightening typically occurs near the end of the third trimester, not the second trimester, as the baby drops lower into the pelvis in preparation for birth. C: Braxton Hicks contractions are typically painless and irregular in the third trimester, not more painful. Pain with exercise could indicate preterm labor. D: Uterine souffle refers to the sound of blood flow through the uterine arteries, not movement of the fetus.
