compressibility and softening of the lower uterine segment
What is Chadwick’s sign?
bluish discoloration of the cervix, vagina, and labia resulting from increased blood flow that can be observed as early as 6 to 8 weeks after conception

Can HgA1c be used to monitor blood glucose during pregnancy?
no - pregnancy changes RBC indicators so HgA1c is unreliable
What is RhoGAM?
injected into the muscle of an Rh-negative mother - antibodies circulate in her bloodstream and protect her against any Rh-positive red blood cells from the fetus => performed at 24-28 weeks, if indicated
What is the procedure for kick counts?

What is placenta abruption?
separation of placenta from the uterine wall - two types: (1) revealed - abruption over the cervix associated with bright red bleeding (80%) and (2) concealed - abruption does not cross cervix with blood pooling between uterus and placenta (20%) => do not perform cervical exam in woman with placenta previa - can cause abruption
What is suggested by the phrase “hard, rigid abdomen” in a pregnant woman?
placenta abruption - need to get to the ED within 10 minutes to save the baby

What is mastitis?
breast inflammation usually caused by infection (Staph aureus is most common) - Tx: amoxicillin/clavulanate (Augmentin), 875 mg BID => pump and dump to maintain mother’s milk supply
What are the various definitions of miscarriage?
threatened (vaginal bleed prior to 20 weeks), inevitable (passage of products of conception [POC]), incomplete (retention of some POC), missed (non-viable pregnancy without bleeding), septic (complicated by infection), recurrent (3 or more consecutive), complete (full expulsion of POC in an intrauterine pregnancy)

What are the s/s of herpes simplex?
discharge: unchanged; pain; viral syndrome; painful vesicular lesions; Tx: antiviral
What is the role of the hypothalamus in the normal menstrual cycle?
produces gonadatropin releasing hormone (GnRH), which stimulates the pituitary to release follicle stimulating hormone (encourages maturation of 1-2 follicles) and estradiol/estrogen (builds up the endometrial lining)
What is the role of leutenizing hormone in the normal menstrual cycle?
causes the release of the dominant follicle out of the ovary - a rise in progesterone hormone indicates to the body that the woman is pregnant and supports the pregnancy until the placenta is strong (decline in progesterone indicates that the woman isn’t pregnant and the uterus sheds the endometrial lining)
Which vulvovaginitis diagnosis is suggested by a pH > 5?
atrophic vaginitis
What is toxic shock syndrome
colonization of Staph aureus that produces exotoxins and triggers an autoimmune response - characterized by rapid onset of symptoms close to time of menstruation => s/s: fever > 38.9 degrees C, hypotension, diffuse erythroderma, desquamation of palms and soles, involvement of >= 3 major organ systems
What is the treatment for toxic shock syndrome?
removal of retained item (e.g., tampon) and Tx with Flagyl or doxycycline
What is the best treatment for premenstrual dysphoric disorder?
depends on the primary complaint; ibuprofen if pain/cramping, antihistamine (hydroxyzine) if sleep disorder, SSRIs (sertraline/Zoloft) if depression
What distinguishes premenstrual dysphoric disorder from regular depression?
PMDD is more cyclical than depression and associated with the menstrual cycle - prescribe 25 mg Zoloft at bedtime one week before menstruation and off for 3 weeks
What is the weight cut off for low dose contraceptives?
150 pounds - pills will not be effective at this or higher weights
How long after an abortion (due to any cause) should a woman wait before attempting conception again?
6 to 12 weeks

What is utilitarianism?
allocation of healthcare resources so that the best is done for the greatest number of people - recognizes that healthcare is a limited resource that needs to be carefully allocated => increased utilization of primary prevention services that are aimed at avoiding health problems can help with healthcare cost savings and help actualize the principle of utilitarianism
What is nonmaleficence?
requirement that the provider do no harm, with or without intention
