Why is glucose metabolism profoundly affected during pregnancy?
The pregnant woman uses glucose at a more rapid rate than the nonpregnant woman.
Placental hormones are antagonistic to insulin, thus resulting in insulin resistance.
Pancreatic function in the islets of Langerhans is affected by pregnancy.
The pregnant woman increases her dietary intake significantly.
The Correct Answer is B
Choice A reason: This is not the correct answer, as the pregnant woman does not use glucose at a more rapid rate than the nonpregnant woman. In fact, the pregnant woman has lower fasting glucose levels and higher postprandial glucose levels than the nonpregnant woman. This is because the pregnant woman adapts to the increased fetal demand for glucose by increasing her insulin secretion and decreasing her hepatic glucose production.
Choice B reason: This is the correct answer, as placental hormones are antagonistic to insulin, thus resulting in insulin resistance. Insulin resistance is a condition where the cells do not respond well to insulin and require more insulin to maintain normal glucose levels. Placental hormones, such as human placental lactogen, progesterone, and cortisol, increase the insulin resistance of the maternal tissues, especially in the second and third trimesters of pregnancy. This is to ensure that the fetus has enough glucose supply, as the placenta is not insulin resistant and can transport glucose to the fetus².
Choice C reason: This is not the correct answer, as pancreatic function in the islets of Langerhans is not affected by pregnancy. The islets of Langerhans are clusters of cells in the pancreas that produce hormones, such as insulin and glucagon, that regulate glucose metabolism. Pregnancy does not impair the function of the islets of Langerhans, but rather stimulates them to increase their size and number. This is to compensate for the increased insulin resistance and glucose demand of the pregnancy.
Choice D reason: This is not the correct answer, as the pregnant woman does not increase her dietary intake significantly. The pregnant woman needs to consume adequate calories and nutrients to support the fetal growth and development, but not excessively. The recommended weight gain during pregnancy depends on the pre-pregnancy BMI of the woman, but generally ranges from 11 to 16 kg. The recommended calorie intake during pregnancy is about 300 kcal more than the pre-pregnancy intake, which is equivalent to one extra snack per day.

Correct Answer is ["A","B","E"]
Explanation
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.
Correct Answer is B
Explanation
Choice A reason: This is incorrect because primary dysmenorrhea is menstrual pain that is not associated with any underlying condition. It usually begins with the onset of menstruation and lasts for a few days. It does not cause pain during intercourse or infertility.
Choice B reason: This is correct because endometriosis is a condition where the endometrial tissue that normally lines the uterus grows outside the uterus, such as on the ovaries, fallopian tubes, or pelvic organs. It causes chronic inflammation, scarring, and adhesions that can result in severe pain during menstruation and intercourse, as well as infertility.
Choice C reason: This is incorrect because secondary dysmenorrhea is menstrual pain that is caused by an underlying condition, such as fibroids, pelvic inflammatory disease, or adenomyosis. It usually develops later in life and lasts longer than primary dysmenorrhea. It may or may not cause pain during intercourse or infertility, depending on the condition.
Choice D reason: This is incorrect because PMS stands for premenstrual syndrome, which is a group of physical and emotional symptoms that occur before menstruation. It may include mood swings, irritability, bloating, headaches, or breast tenderness. It does not cause severe pain during menstruation or intercourse, or infertility.
