As of October 1979, all 22 member boards of the American Board of Medical Specialties committed themselves to the principle of periodic recertification of their members. Despite the Board’s recognition that the cognitive skills measured in the objective examination do not assure clinical competence, recertification efforts—insofar as they involve examinations—are based on the assumption that knowledge of current information on which good clinical decisions should be made is worth cultivating; that, while such information does not guarantee com- petent practice, lack of it probably impedes competent practice; that this knowledge, unlike technical skills, is reasonably easy to assess; and that it can be acquired by well-motivated physicians. These assumptions all seem reasonable. The questions presented in this book deal with issues of relative importance to medical students; other problem-oriented materials are becoming available that are aimed at more sophisticated audiences— groups that, within a very few years, will include the present generation of students. Regular review of such material is a habit worth developing. We hope that this edition of Obstetrics and Gynecology: PreTest® Self-Assessment and Review will justify your efforts in working through the problems by providing guidance for further study and by helping you to develop endur- ing learning habits.

The 500 questions provided have been designed to parallel the format of the questions con- tained in Step 2 of the United States Medical Licensing Examination (USMLE). Each question in the book is accompanied by an answer, a paragraph explanation, and a specific page reference to a current textbook. A bibliog- raphy that lists all the sources used in the book follows the last chapter. Perhaps the most effective way to use this book is to allow yourself one minute to answer each question in a given chapter; as you proceed, indi- cate your answer beside each question. By following this suggestion, you will be approximating the time limits imposed by licensing examinations. When you practice your examination-taking skills with this PreTest®, one way to maximize your score is to go through, answer all the questions you find easy, and skip over the more difficult ones initially. We do recom- mend, however, that once you come back to the more difficult questions, you spend as much time as you need.

  • Ectopic Pregnancy
    Ectopic pregnancy Reviewed By Peter Chen MD, Department of Obstetrics & Gynecology, University of Pennsylvania Medical «more » Definition An ectopic pregnancy is an abnormal pregnancy that occurs outside the womb (uterus). The baby cannot survive. Alternative Names Tubal pregnancy; Cervical pregnancy; Abdominal pregnancy Causes, incidence, and risk factors An ectopic pregnancy occurs when the baby starts to develop outside the womb (uterus). The most common site for an ectopic pregnancy is within one of the tubes through which the egg passes from the ovary to the uterus (fallopian tube). However, in rare cases, ectopic pregnancies can occur in the ovary, stomach area, or cervix. An ectopic pregnancy is usually caused by a condition that blocks or slows the movement of a fertilized egg through the fallopian tube to the uterus. This may be caused by a physical blockage in the tube. Most cases are a result of scarring caused by: y Past ectopic pregnancy y Past infection in the fallopian tubes y Surgery of the fallopian tubes Up to 50% of women who have ectopic pregnancies have had swelling (inflammation) of the fallopian tubes (salpingitis) or pelvic inflammatory disease (PID). Some ectopic pregnancies can be due to: y Birth defects of the fallopian tubes y Complications of a ruptured appendix y Endometriosis y Scarring caused by previous pelvic surgery In a few cases, the cause is unknown. Sometimes, a woman will become pregnant after having her tubes tied (tubal sterilization). Ectopic pregnancies are more likely to occur 2 or more years after the procedure, rather than right after it. In the first year after sterilization, only about 6% of pregnancies will be ectopic, but most pregnancies that occur 2 - 3 years after tubal sterilization will be ectopic.
