Chapter 15, Problem 1BCTQ
Summary Introduction
To explain: The difficulties that researchers encounter in trying to determine the exact amount of alcohol and the timing during pregnancy that might be reasonably safe for fetal development.
Concept introduction: Drinking alcohol during pregnancy can cause serious health problems to the fetus. When alcohol is consumed, it passes through the placenta and the umbilical cord to the fetus. This affects the development of the central nervous system and other organs of fetus.

Students have asked these similar questions
In-vitro fertilization occurs in the laboratory. The resulting embryos remain in a laboratory culture for up to six days before being transferred to the potential mother. If fertilization had occurred naturally (i.e., inside the female reproductive system instead of in-vitro), where would the embryo be and what developmental processes would it be undergoing during those first six days of development?
During pregnancy, how does malnutrition during critical periods of development affect the fetus?
Group of answer choices
When the development of an organ is impaired, the damage is irreversible.
If the development of the heart is impaired in the early stages, it can be reversed if good nutrition is provided after the critical period.
Malnutrition does not affect the fetus but has adverse effects on the mother's health.
Malnutrition does not cause dental problems as teeth develop after the baby is born.
A surplus of nutrients taken after the critical period will make up for a deficit caused at any time during development.
During the organogenesis stage, several of the five essential developmental processes take place.
Choose two of these essential processes and describe how and when they occur during the
organogenesis stage. Be specific about the cells, tissues, and organs involved and the results.

However, although the evidence is clear that a mother’s heavy consumption is dangerous to the fetus, the effects, if any, of light alcohol consumption on the fetus are far more ambiguous. In view of the current state of knowledge, do you think it is ethical to give blanket, prescriptive-like advice to women to not drink alcohol if they are pregnant? In considering your answer, consult the articles by Gavaghan (2009), Kelly et al. (2009), and Murray et al. (2016).arrow_forward
- Discussion: Fetal Development Marie Tamasin is a quiet shy, 35-year-old woman from Port Au Prince, Haiti, who arrives at the doctor’s office with her husband Jean. Jean tells the nurse that in Haiti, a multiple marker screen blood test was done, and they were told it was abnormal. Marie expresses ambivalence about the pregnancy, stating, “I’m really scared. I had a miscarriage 6 month ago. She complains of tender breasts and intermittent nausea. Her last menstrual period was June 10. 1. What is Marie’s GTPAL, and due date? (Using the GTPAL) And explain how you calculate a due date. 2. When is this test normally done? Explain what this test is and what are the implications of this test? 3. How might Marie’s cultural background affect the nurse-client relationship and what might the nurse do to become more culturally competent? 4. Marie is scheduled for an amniocentesis. The nurse askes if she has any questions about the test. Marie says, “I’m afraid the baby will be…arrow_forwardKatie is 37 years old and about 20 weeks pregnant. When Dr. Crusher talks to a patient about scheduling their ultrasound, she simply tells them that it is a way to check on the progress of the pregnancy. However, Dr. Crusher knows that Katie is very worried about fetal anomalies. Dr. Crusher also carefully explains what exactly they will be looking for on the ultrasound as well as what fetal anomalies might be detected by the ultrasound. What standard goes with this? reasonable person standard professional standard subjective starrow_forwardA pregnant woman visits the doctor. The GP decides to request ultrasound imaging to check on the pregnancy. Describe why ultrasound is the imaging technique of choice to monitor foetal development in the womb. Describe how ultrasound can be used to provide diagnostic images in medicine. Highlight the role of sound for imaging and describe how sound is generated and received. Explain in detail which physical properties of human tissue is exploited by this technique. Describe the ultrasound technique that can be used to monitor blood flow and diagnose diseases that impact blood flow. Explain the physical principles underlying magnetic resonance imaging and provide three examples where it could be used to provided information not accessible with ultrasound. [9]arrow_forward
- The development of sex and gender is a good example of a developmental cascade because: Group of answer choices Although having an X and a Y chromosome at conception typically leads to the development of testes during prenatal development, this may not lead to typical male genitalia if certain hormones are present later in development Two people may have the same gonads early in prenatal development but end up with different external genitalia and gender identities as a result of differences in the prenatal environment All of the options listed here are correct Having two X chromosomes at conception typically leads to the development of ovaries during prenatal development, which typically leads to high levels of estrogen in puberty, which typically leads to a female gender identity in adulthoodarrow_forwardDescribe the difference between Amniocentesis and Chorionic villus sampling.
