Observation 1: 1 out of 2 first trimester abortuses show abnormal karyotypes with 96% caused by numerical abnormalities and 4% with structural abnormalities. At live birth, 1 out of 160 has abnormal karyotypes with 60% caused by numerical changes. This number increases with fetuses of mothers over 35 years old to 1/50 for total incidence and 85% for numerical changes.
Questions:
- Think of reasons why it is important to maintain the number and structure of chromosomes.
- Why is maternal age so important?

- A primigravida at 43 weeks’ gestation was admitted for labor induction by IV Pitocin therapy 3 hours ago. On observation on the external monitor tracing, the nurse notes that with the last two contractions, the fetal heart rate decreased after the contraction peak and returned to baseline after the contraction ended. A decrease in variability is also noted. What is the pattern identified by the nurse and the possible reasons responsible for it? What actions should the nurse take?Pregnant women are exposed to some physiological and psychological changes during the prenatal period. The aim of the study is to determine the effect of age factor on these physiological and psychological changes during pregnancy. The study included all adolescent (15-18 years) adult (19-34 years) and advanced age (35 years and above) pregnant women who applied to the clinic for 8 months in March 2003, and a total of n = 150 pregnant women, n = 50 from each group, were included in the study. is included. The research is planned as descriptive comparative. In the findings, it was found that there was a statistically significant difference in fatigue, frequent urination and respiratory distress compared to age groups (p <0.05). As a result of the study, it was revealed that age is not an important factor in both physiological and psychological changes of pregnant women.

The physician was able to palpate several small cysts and other signs of fibrocystic changes, but felt no dominant mass and told her to return in 6 weeks. She returned and the physician could palpate nothing at that time. She returned in 3 months and test showed the same result. At her annual test in May, 1998, a mass was palpated at 9 o’clock in the right breast. She had a negative mammogram, but the ultrasound was positive for a solid mass. Excisional biopsy showed infiltrating ductal carcinoma. She had no positive nodes, underwent mastectomy with reconstruction and is still cancer-free. questions: 1. The patient alleges failure to diagnose breast cancer and that mammography or biopsy should have been done in October 1997. What do you think? 2. What comments can you make about what you would “expect” in someone her age?…
- t of 1 One cause of male infertility is congenital absence of the vas deferens (CAVD). An individual with CAVD is born without a portion of the epididymis, vas deferens, and seminal vesicle, resulting in the obstruction of the passage of sperm from the testes. In order to father a child, those with CAVD must undergo surgical aspiration of sperm cells from the testes to be used for in vitro fertilization. Select one: OA. Structure b OB. Structure d OC. Structure e OD. Structure f 你 b d The structure from which sperm cells must be retrieved, in order for an individual for CAVD to produce children isP.T.’s history reveals that she had 1 preterm delivery four years ago at 31 weeks gestation. The infant girl was in the neonatal intensive care unit (NICU) for three weeks and discharged without sequelae. The second preterm infant, a boy was delivered two years ago at 35 weeks gestation and spent 4 days in the hospital before discharge. She has no other risk factors for preterm labor. Vital signs are normal. Her vaginal examination was essentially within normal limits (WNL): cervix long, closed, and thick; membranes intact. Abdominal examination revealed that abdomen was non-tender, with fundal height at 29 cm, fetus in a vertex presentation. 5. While you are waiting for the laboratory results, what therapeutic measures do you consider?A full-term male newborn has enlargement of head circumference (3 cm greater than 99% of age range). Body weight is appropriate for gestational age. The cranial sutures are separated. Ultrasonography of the head shows enlargement of the lateral ventricles and thinning of the cerebral cortex. The newborn's maternal uncle had similar abnormalities. Further anatomic studies are most likely to show which of the following? A) Absence of the foramina of Luschka B) Cerebellar astrocytoma C) Holoprosencephaly D) Neurofibromatosis E) Stenosis of the aqueduct of Sylvius F) Tuberous sclerosis
