Anatomy and Physiology of Pregnancy Quizlet Questions
Question 1 of 5
Which statement about a condition of pregnancy is accurate?
Correct Answer: C
Rationale: The correct answer is C because hyperthyroidism can indeed develop during pregnancy due to the increase in hormone production, specifically human chorionic gonadotropin (hCG) stimulating the thyroid gland. This can lead to symptoms such as weight loss, anxiety, and palpitations. Other choices are incorrect because A is false - ptyalism is actually linked to progesterone levels, not estrogen. B is incorrect because acid indigestion tends to worsen as pregnancy progresses, not decline. D is incorrect as severe nausea and vomiting, known as hyperemesis gravidarum, can have harmful effects on both the mother and fetus if not properly managed.
Question 2 of 5
Physiologic anemia often occurs during pregnancy as a result of:
Correct Answer: B
Rationale: Physiologic anemia during pregnancy occurs due to the expansion of plasma volume, causing a dilution of hemoglobin concentration. Increased blood volume is necessary to support the growing fetus, leading to a relative decrease in hemoglobin levels. Inadequate iron intake (Choice A) can cause iron-deficiency anemia but is not the primary reason for physiologic anemia in pregnancy. The fetus establishing iron stores (Choice C) is unrelated to the maternal anemia. Decreased production of erythrocytes (Choice D) is not the main cause of anemia in pregnancy; rather, it is the dilution effect from increased plasma volume.
Question 3 of 5
The diagnosis of pregnancy is based on which positive signs of pregnancy? (Select all that apply.)
Correct Answer: A
Rationale: Step-by-step rationale for choice A (Identification of fetal heartbeat) being correct: 1. Detection of fetal heartbeat confirms the presence of a developing fetus. 2. It is a definitive sign of pregnancy and indicates fetal viability. 3. Fetal heartbeat can be detected using ultrasound or Doppler. 4. This sign is not subject to interpretation or misinterpretation. Summary of why the other choices are incorrect: - Choice B (Palpation of fetal outline) and D (Verification of fetal movement) are considered probable signs of pregnancy and do not provide definitive confirmation. - Choice C (Visualization of the fetus) is not a reliable sign as it requires advanced imaging techniques and can be subjective.
