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.

Answer and Explanation

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 B

Explanation

The correct answer is: B. 3-1-1-0-3.

Choice A reason:

This option suggests the woman has been pregnant four times, which is incorrect. She has had three pregnancies: one set of twins (counted as one pregnancy) and two singletons.

Choice B reason:

This is the correct option. The woman has had three pregnancies (Gravida = 3), one full-term delivery (Term = 1), one preterm delivery (the twins, Preterm = 1), no abortions (Abortions = 0), and three living children (Living = 3).

Choice C reason:

This option incorrectly suggests two preterm deliveries and one abortion, neither of which is indicated in the woman's history.

Choice D reason:

This option incorrectly suggests two preterm deliveries (the twins are counted as one preterm delivery) and does not accurately reflect the woman's history.

GTPAL stands for Gravida (total number of pregnancies), Term births (deliveries after 37 weeks), Preterm births (deliveries between 20-36 weeks), Abortions (losses before 20 weeks), and Living children. Normal ranges: Term (≥37 weeks), Preterm (20-36 weeks)

A. Limit time spent wearing a wet bathing suit B. Do not douche. C. Wear nylon undergarments D. Use floral scented bath salts E. Decrease sugar intake. F. Avoid tight-fitting jeans.

Correct Answer is ["A","B","E","F"]

Explanation

Choice A reason: Limiting time spent wearing a wet bathing suit is a good preventive measure, as it can reduce the moisture and warmth that can promote the growth of bacteria and fungi in the genital area. The nurse should advise the 15-year old to change into dry clothes as soon as possible after swimming or bathing.

Choice B reason: Not douching is a good preventive measure, as it can preserve the natural balance of the vaginal flora and pH. The nurse should explain to the 15-year old that douching can wash away the protective mucus and lactobacilli that prevent infections, and it can also introduce harmful substances or microorganisms into the vagina.

Choice C reason: Wearing nylon undergarments is not a good preventive measure, as it can trap heat and moisture in the genital area and create a favorable environment for infections. The nurse should recommend the 15-year old to wear cotton or breathable fabrics that can absorb sweat and allow air circulation.

Choice D reason: Using floral scented bath salts is not a good preventive measure, as it can irritate the genital mucosa and alter the vaginal pH. The nurse should caution the 15-year old to avoid using any products that contain perfumes, dyes, or chemicals in the genital area, as they can cause allergic reactions or infections.

Choice E reason: Decreasing sugar intake is a good preventive measure, as it can lower the risk of yeast infections. The nurse should educate the 15-year old that sugar can feed the growth of Candida albicans, which is a common cause of vaginal candidiasis. The nurse should also encourage the 15-year old to eat a balanced diet that includes probiotics, such as yogurt, to maintain a healthy vaginal flora.

Choice F reason: Avoiding tight-fitting jeans is a good preventive measure, as it can prevent friction and pressure on the genital area. The nurse should suggest the 15-year old to wear loose or comfortable clothing that can reduce the risk of skin irritation or injury, which can lead to infections.
