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 C
Explanation
Choice A reason: The order in which the information is presented is not the most important factor, as it does not affect the client's motivation or ability to learn. The order of the information should be logical and sequential, but it can vary depending on the client's needs, preferences, and learning style. The nurse should assess the client's prior knowledge and tailor the teaching accordingly.
Choice B reason: The extent to which the pregnancy was planned is not the most important factor, as it does not determine the client's interest or willingness to learn. The pregnancy may be planned or unplanned, but the client may still have questions, concerns, or goals related to the pregnancy. The nurse should respect the client's feelings and emotions and provide support and guidance.
Choice C reason: The client's readiness to learn is the most important factor, as it influences the client's engagement and retention of the information. The client's readiness to learn depends on the client's perception of the relevance, importance, and benefits of the information, as well as the client's physical, psychological, and social readiness. The nurse should assess the client's readiness to learn and use appropriate strategies to enhance it, such as setting realistic and specific objectives, providing positive feedback, and involving the client in the learning process.
Choice D reason: The client's educational background is not the most important factor, as it does not reflect the client's learning needs or capabilities. The client's educational background may vary, but the client may still have similar or different learning needs depending on the pregnancy situation. The nurse should not assume the client's level of understanding or knowledge based on the client's educational background, but rather use simple and clear language, avoid medical jargon, and check for comprehension.
Correct Answer is C
Explanation
Choice A reason: This is incorrect because providing the patient with handouts is not enough to ensure effective communication. The handouts may not be in the patient's preferred language or may use unfamiliar words or concepts. The nurse should also use other methods, such as interpreters, translators, or visual aids, to convey information to the patient.
Choice B reason: This is incorrect because speaking quickly and efficiently may hinder the patient's comprehension and increase the risk of misunderstanding. The nurse should speak slowly and clearly, using simple and common words, and allow time for the patient to ask questions or clarify information.
Choice C reason: This is correct because assessing whether the patient understands the discussion is essential for effective communication and patient education. The nurse should use techniques such as teach-back, ask-me-3, or show-me to verify the patient's understanding and address any gaps or misconceptions.
Choice D reason: This is incorrect because using maternity jargon may confuse the patient and create barriers to communication. The nurse should avoid using medical terms, abbreviations, or slang that the patient may not be familiar with. The nurse should explain any necessary terms in plain language and use examples or analogies to illustrate them.
