What is the most dangerous effect on the fetus of a mother who smokes cigarettes while pregnant?

Choice A reason: Low birth weight is not a common complication of GDM, as the fetus tends to grow larger than normal due to the excess glucose and insulin in the blood. Low birth weight is more likely to occur in infants of mothers with preexisting diabetes or other conditions that affect placental function.

Choice B reason: Preterm birth is a possible complication of GDM, as the increased fetal size and the risk of maternal hypertension or infection may induce labor before term. However, it is not the greatest risk for the fetus, as preterm infants can survive with proper care and treatment.

Choice C reason: Macrosomia is the greatest risk for the fetus of a mother with GDM, as it is defined as a birth weight of more than 4000 g or 8 lb 13 oz. Macrosomia can cause difficulties during labor and delivery, such as shoulder dystocia, birth trauma, or cesarean birth. It can also increase the risk of neonatal hypoglycemia, jaundice, or respiratory distress.

Choice D reason: Congenital anomalies of the central nervous system are not a common complication of GDM, as they usually occur in the first trimester of pregnancy, before GDM is diagnosed or develops. Congenital anomalies are more likely to occur in infants of mothers with preexisting diabetes or other genetic or environmental factors.

Choice A reason: Women without pain and who do not want to become pregnant need no treatment, as endometriosis is a benign condition that does not affect the general health or well-being of the woman. The nurse should explain to the client that endometriosis is a chronic condition that causes the growth of endometrial tissue outside the uterus, and that it can cause symptoms such as pelvic pain, dysmenorrhea, dyspareunia, and infertility. However, if the woman is asymptomatic and has no desire for pregnancy, she can choose to monitor the condition without any intervention.

Choice B reason: Surgical intervention often is needed for severe or acute symptoms, as endometriosis can cause complications such as adhesions, cysts, inflammation, or obstruction of the pelvic organs. The nurse should inform the client that surgery can be performed to remove or destroy the endometrial implants, or to perform a hysterectomy or oophorectomy in severe cases. The nurse should also discuss the benefits and risks of surgery, and the possibility of recurrence or persistence of symptoms.

Choice C reason: Side effects from the steroid danazol include masculinizing traits, as danazol is a synthetic androgen that suppresses the ovarian function and reduces the production of estrogen and progesterone. The nurse should warn the client that danazol can cause adverse effects such as acne, hirsutism, weight gain, voice changes, decreased breast size, and menstrual irregularities. The nurse should also advise the client to use a non-hormonal contraceptive method while taking danazol, as it can harm the fetus if pregnancy occurs.

Choice D reason: Bone loss from hypoestrogenism is not irreversible, as it can be prevented or treated with calcium and vitamin D supplements, bisphosphonates, or hormone replacement therapy. The nurse should educate the client that hypoestrogenism is a condition where the estrogen levels are abnormally low, and that it can occur as a result of some medications or surgical procedures for endometriosis. The nurse should also explain that hypoestrogenism can increase the risk of osteoporosis, which is a condition where the bones become weak and brittle.

Choice E reason: Women with mild pain who may want a future pregnancy may take nonsteroidal anti-inflammatory drugs (NSAIDs), as NSAIDs can reduce the inflammation and pain caused by endometriosis. The nurse should recommend the client to take NSAIDs as needed, and to follow the dosage and instructions on the label. The nurse should also inform the client that NSAIDs are not effective in treating the underlying cause of endometriosis, and that they may have side effects such as gastrointestinal irritation, bleeding, or ulcers.
