Which factor is known to increase the risk of gestational diabetes mellitus?

The correct answer is d. Amenorrhea.

Choice A: Chadwick’s sign is a non-specific, early sign of pregnancy that is typically characterized by a bluish discoloration of the cervix, vagina, and vulva. The Chadwick sign can typically be observed as early as six to eight weeks after conception, and commonly disappears shortly after birth. However, it’s not a definitive indication of pregnancy, and the absence of it on physical exam does not exclude a potential pregnancy.

Choice B: Hegar’s sign is a non-specific indication of pregnancy that is characterized by the compressibility and softening of the cervical isthmus (i.e., the portion of the cervix between the uterus and the vaginal portion of the cervix). It typically presents between the fourth and sixth week of pregnancy and may be present until the 12th week of pregnancy. However, the Hegar sign is not a definitive indication of pregnancy, and the absence of it does not exclude a potential pregnancy.

Choice C: A positive pregnancy test By 10 weeks, a home pregnancy test would almost certainly show a positive result if the woman is pregnant. This is because the hormone human chorionic gonadotropin (hCG), which is produced by the placenta after implantation of the embryo into the uterine wall, would be present in high enough levels to be detected by the test. However, a positive pregnancy test is not a presumptive sign of pregnancy, but rather a probable one.

Choice D: Amenorrhea, or the absence of menstrual periods, is often considered the most presumptive sign of pregnancy. This is because it’s one of the first noticeable signs of pregnancy for many women. By 10 weeks of gestation, the woman would likely have missed two menstrual periods if she usually has regular cycles. However, while amenorrhea is a common early sign of pregnancy, it can also be caused by various other conditions or factors such as stress, significant weight loss or gain, or certain medical conditions. Therefore, a missed period should be followed up with a pregnancy test to confirm pregnancy.

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.
