Answer to Question 1

ANS: B, C, D, E
The most common cause of loss of fetal heart rate reactivity is a fetal sleep cycle. Other causes are related to central nervous system depression (not irritability) and can include fetal acidosis, hypoxia, and certain congenital abnormalities.

Answer to Question 2

ANS: A, B, C, E
Patients who experience habitual (three or more) spontaneous abortions may be offered these tests as part of the diagnostic workup: a karyotype obtained from the products of conception and from both parents and an examination of the maternal anatomy, beginning with a hysterosalpingogram . Additional testing may include hysteroscopy or laparoscopy; screening tests for maternal hypothyroidism, diabetes mellitus, antiphospholipid syndrome (APS), and systemic lupus erythematosus (SLE); testing of the serum progesterone level during the luteal phase of the menstrual cycle; cultures of the cervix, vagina, and endometrium; and endometrial biopsy during the luteal phase of the menstrual cycle. Sickle cell screening would not be part of this workup.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
