- Mr. and Mrs. Smith have arrived for their first fertility appointment after trying unsuccessfully to get pregnant for the past year. Mrs. Smith is withdrawn, her voice is monotone, and she becomes tearful when the nurse begins to take a health history. Mr. Smith hugs her and holds her hand, but Mrs. Smith doesn't seem to notice. What is the best nursing action to take at this time? O Get a box of tissues and encourage Mrs. Smith to discuss what she's feeling. O Ask Mr. Smith to leave the room and ask Mrs. Smith if she feels safe at home and how long she's been abused. O Tell Mrs. Smith she's being silly; the clinic will make everything better. O Continue taking the history; this is just part of the job.arrow_forwardWhat is a spontaneous abortion? a therapeutic abortion?arrow_forwardWhat disorder can a baby develop if the mother consumes alcohol during pregnancy?arrow_forward
- What is Postpatagium?arrow_forwardHow might the following individuals respond to or feel about these definitions? 1)A woman who ended a pregnancy, for whatever reason 2)A couple who have had a spontaneous abortion 3)A person with a disease that one day may be treated with stem cells. 4)A couple who have unsuccessfully tried to conceive for a decade.arrow_forwardIf the child showed a cleft lip through ultrasound analysis and the parents then started blaming each other (because Sue is a smoker and Tim was born with the defect), how would you counsel them? Sue and Tim were referred for genetic counseling after they inquired about the risk of having a child with a cleft lip. Tim was born with a mild cleft lip that was surgically repaired. He expressed concern that his future children could be at risk for a more severe form of clefting. Sue was in her 12th week of pregnancy, and both were anxious about the pregnancy because Sue had had a difficult time conceiving. The couple stated that they would not consider terminating the pregnancy for any reason but wanted to be prepared for the possibility of having a child with a birth defect. The genetic counselor took a three-generation family history from both Sue and Tim and found that Tim was the only person to have had a cleft lip. Sues family history showed no cases of cleft lip. Tim and Sue had several misconceptions about clefting, and the genetic counselor spent time explaining how cleft lips occur and some of the known causes of this birth defect. The following list summarizes the counselors discussion with the couple. Fathers, as well as mothers, can pass on genes that cause clefting. Some clefts are caused by environmental factors, meaning that the condition didnt come from the father or the mother. One child in 33 is born with some sort of birth defect. One in 700 is born with a cleft-related birth defect. Most clefts occur in boys; however, a girl can be born with a cleft. If a person (male or female) is born with a cleft, the chances of that person having a child with a cleft, given no other obvious factor, is 7 in 100. Some clefts are related to identifiable syndromes. Of those, some are autosomal dominant. A person with an autosomal dominant gene has a 50% probability of passing the gene to an offspring. Many clefts run in families even when there does not seem to be any identifiable syndrome present. Clefting seems to be related to ethnicity, occurring most often among Asians, Latinos, and Native Americans (1 : 500); next most often among persons of European ethnicity (1 : 700); and least often among persons of African origin (1 : 1,000). A cleft condition develops during the fourth to the eighth week of pregnancy. After that critical period, nothing the mother does can cause a cleft. Sometimes a cleft develops even before the mother is aware that she is pregnant. Women who smoke are twice as likely to give birth to a child with a cleft. Women who ingest large quantities of vitamin A or low quantities of folic acid are more likely to have children with a cleft. In about 70% of cases, the fetal face is clearly visible using ultrasound. Facial disorders have been detected at the 15th gestational week of pregnancy. Ultrasound can be precise and reliable in diagnosing fetal craniofacial conditions.arrow_forward
- What leads to teenage pregnancy?arrow_forwardAs the nurse working on a postpartum unit, you are caring for John and Janah, who have just become parents of a 7 lb and 2 oz baby boy. As you prepare them for discharge, you notice that they seem overwhelmed with much of the information being provided. Janah says, “ Maybe my breasts are too small and the baby can’t get enough milk.” She added, “I am hoping that if I breastfeed, I won’t have to worry about birth control for a while.” GUIDE QUESTIONS: The couple needs health teaching in a number of areas. Which subject would you begin with? Why? Explain how breastfeeding can prevent pregnancy? How can you best explain this to the couple?arrow_forwardSam and Regina are new parents and want to do the best thing for their baby. Sam says they should put their baby on a low-fat diet right from the beginning. What advice would you give these new parents? 1) They are correct and the baby should eat no more than 35% of his or her calories. 2) They are correct and the baby should only drink skim milk as a beverage. 3) They are incorrect; from birth to 2 years of age, a child's fat consumption should not be restricted for proper development. 4) The healthiest diet for everyone is a vegan diet.arrow_forward
