Whether multiple pregnancies increase the relative risk of chromosomal defects in offspring. Introduction: A study was conducted in Florida during the time span of 1996–2000 on the newborns. This study was conducted on the prevalence of birth defects among the newborns per 10,000 live births. The study also included the prevalence of the defects among multiple and single births. The relative risk was also calculated for each defect. Birth defects are functional or structural abnormalities that are present in a newborn. These may develop either before or at the time of birth.

According to the results obtained, give your opinion as to whether there is an association or not and express it accordingly.C) Relative risk for the factor "mothers with previous HTN". According to the results obtained, give your opinion as to whether or not there is an association and express it accordingly.D) In the case of the factors in which you consider, according to the results obtained, that there is an association, calculate the Attributable Risk (AR) and the Etiological Risk Fraction (ERF), expressing in both cases their significance.

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.
