Which of the following statements is NOT true regarding pregnancy?

The statement regarding the uterus enlarging and rising out of the pelvis as pregnancy progresses is true and accurately describes the physiological changes that occur during pregnancy. As the fetus grows, the uterus expands significantly, which raises it above the pelvic brim around the end of the first trimester and continues to grow throughout the pregnancy. This is an important aspect of maternal physiology as it accommodates the developing fetus.

In contrast, the other statements address various aspects of pregnancy and its complications or cultural considerations. Gestational diabetes typically resolves after delivery, which reflects the temporary nature of this condition related to hormonal changes during pregnancy. The leading cause of abrupt placenta is not an ectopic pregnancy, as abruptio placentae is more commonly associated with factors such as trauma or maternal hypertension rather than the site of a developing pregnancy. Finally, cultural beliefs can indeed impose restrictions on who may perform examinations on patients, which highlights the importance of cultural competence in healthcare.

Thus, statement C accurately reflects a key aspect of pregnancy development, while the other statements touch on important considerations and conditions that may arise during pregnancy.
