TAQ 3: Assessment criteria 2.1 Part 1 a) The zygote that is formed after fertilisation divides rapidly during the first 2 weeks of pregnancy, developing into an embryo by day 12. With reference to specific structures formed, outline this period of development from conception up to the 28th day of gestation. b) Summarise the key developmental changes that occur from the point that the embryo is formed up to the end of the 1st trimester of pregnancy when the embryo is considered a foetus. c) What is the approximate size of the foetus by the end of this trimester?

Guide Questions: 1. We have discussed chromosomal and gene-linked abnormalities that can affect prenatal development. How are the symptoms of the related conditions or risks similar to or different from those caused by teratogens or other hazards? 2. If you are a female, what can you do to adjust effectively in the postpartum period? If you are a male, what can you do to help your partner during the postpartum period?
CASE STUDY Chin Won, age 26 years, presents at the com- munity health center in her last trimester of pregnancy for her initial prenatal care visit. She is found to have an elevated blood pressure and excessive swelling in her legs and feet. The fetus appears small on the sonogram. Explain how things could have been different if Chin Won had sought prenatal care during her first trimester. What measures might the nurse take to ensure that Chin Won's care is family centered? What cultural aspects would be important to assess when planning Chin Won's care throughout the pregnancy and puerperium?

Q.1. Explain the role of pituitary gonadotropins during the follicular and ovulatory phases of the menstrual cycle. Describe the shifts in steroidal secretions.
nal 1. What are the different phases of a menstrual cycle? How do hormone levels change during the different phases? Describe follicular development. 2. What do the hormone levels tell you about the patient? What is hCG, how and when is it produced and why? 3. A transvaginal ultrasound was performed and found more than 12 follicles/ovary and an ovarian volume of >10cc. What is the normal range of primordial (antral) follicles/ovary? What is your potential diagnosis? 4. Can this couple conceive? What are the hormonal changes during pregnancy and when do they occur (fertilization to birth)? Describe the fertilization process. ners
10 Activity 2 Answers Only Directions: Identify what phase of menstrual cycle is described in each number. 1. The lining of the uterus becomes thin after menstruation. An egg in the ovary continues to mature. Just before the mid-cycle, the mature egg moves to the surface of the ovary. 2. The lining of the uterus called endometrium becomes thicker in preparation for implantation of the fertilized egg. If fertilization does not take place, menstruation happens. The next cycle is then about to begin. 3. This occurs when fertilization does not take place. The uterine lining begins to break down and bleeding results. Menstrual fluid contains blood cells and mucus flow and lasts from 3 to 7 days. 4. The mature egg is released and travels to the fallopian tube and toward the uterus.
