Q

Why are pregnant women at increased risk of UTI?

A

Mostly due to urinary stasis induced by progesterone

Maybe a slight argument for increased glycosuria, but it is not that significant

Q

In the case of intrauterine fetal demise at term, ___ is NEVER worth it

A

In the case of intrauterine fetal demise at term, C section is NEVER worth it

You can NEVER justify this, the surgery is too dangerous for mom. But, you also can’t leave the fetus in there as it will cause DIC.

Vaginal delivery is the correct treatment here. Labor may need to be induced with oxytocin or misoprostol the same way it is for a live infant.

40
Treating candida in pregnancy
Topical clotrimazole is the way to go Oral azoles are contraindicated in pregnancy
41
Chancre lesion vs chancroid lesion
Chancres have raised, indurated borders Chancroid has thin borders, but a very necrotic base
42
Rules for preeclampsia magnesium
* Loading of 6g, then maintenance of 2g * Give if there are severe features OR depending on local guidelines without severe features * Continue for 24 hours postpartum (including for cesarean section)
43
"Beta complete"
One dose of betamethasone, 24 hours later another, then 24 hours later for that one to have its full effect ~48 hours in total from start
44
Breast mass with leaf-like projections on histology
Phyllodes tumor
45

54
Adjuvant to utertonics in treating PPH
IV Estrogen Estrogen can sensitize uterine tissue to uterotonics
55
Next best step in management PCOS question
NBME loves to ask this question. Routine care of a PCOS patient in late 30's to 40's includes a screening endometrial biopsy. The question will be framed as routine care for someone with PCOS who is asymptomatic.
56
If an NST is non-reactive in prenatal care, the next step is. . .
. . . **biophysical profile** NST, amniotic fluid volume, fetal breathing, movement, fetal tone
57
You see a sinusoidal pattern on FHRT. What is the next step?
Percutaneous umbilical blood sampling to check hematocrit and O2 sat of the fetus
58
Presentation and treatment of choriocarcinoma
Often presents with either pulmonary symptoms (due to high pulmonary metastasis rate) or hyperthyroidism (due to extremely high bHCG) May follow molar pregnancy Methotrexate is highly effective as treatment
59
Woman comes to first prenatal visit and is found to be Rh- and anti-RhD positive. What is the next step?
Check dad's Rh status If he is Rh-, you are all set. If he is Rh+, you will need to check the fetus. If it is Rh+, regular MCA flow screenings are indicated to assess fetal status. May require intrauterine transfusions to prevent hydrops fetalis.
60
Management of detected placenta previa prior to 32 weeks
No need for immediate delivery as it may change position, however we should administer drugs to hedge our bets against prematurity now. So, give betamethasone and Mg. Plan to deliver ~34 weeks if it persists by this time. An obviously, mom needs pelvic rest -- nothing in the vagina.
61
What is the downside of indomethacin as a tocolytic?
Possibility of premature ductus arteriosus closure NBME loves to test this fact.
62
Highly tested risk factors for preterm labor
Perineal Infection (BV, UTI) Bicornuate uterus
63
Polyhydramnios associations
Maternal diabetes Duodenal atresia (double bubble sign) Anencephaly (no swallowing center) Esophageal atresia

65
After you place a cerclage, the patient should not. . .
. . . **exercise**
66
"Machine like murmur in a newborn" along with features of teratogenciity should make you think. . .

. . . **periventricular**
68
Meningitis, pneumonia, or sepsis in the month of life
Group B strep
69
Ovarian cancer with Psammoma bodies
Serous cystadenocarcinoma
70
"Anterior mediastinal masses"
Often dermoid cysts / mature teratomas
71
Amniotomy
Fancy word for artificial rupture of membranes May be performed prior to moving to pitocin if a patient is arrested in the active phase of labor and has not SROMed. If AROM and pitocin fails to induce progression, Cesarean delivery is indicated.
72
Blood per vagina and signs of fetal distress following ROM indicates. . .
. . . **vasa previa or placental abruption** If mom has symptoms too (particularly pain), abruption is likely, especially if she had polyhydramnios. If mom has no symptoms, vasa previa is likely.
73
"Bloody show"
Small amount of mucousy vaginal bleeding that may occur with onset of labor due to cervical irritation Not clinically significant, very common
74
Most frequent cause of preterm labor
Idiopathic Don't be fooled when they put "cervical insufficiency" or "infection" as answers.
75
Contraindications to tocolytics
Magnesium sulfate: Mysasthenia gravis Terbutaline: Diabetes (causes hyperglycemia) Indomethacin: EGA \>/= 33 wks (premature ductus closure) Nifedipine: Hypotension
76
Preterm labor with chorioamnionitis is an indication for. . .
. . . **augmentation of labor (oxytocin)**
77
If fibronectin is negative, you don't need to give \_\_\_
If fibronectin is negative, you don't need to give **steroids**
78
\_\_\_ decelerations may be amenable to amnioinfusion, but ___ decelerations will not be
**Variable** decelerations may be amenable to amnioinfusion, but **late** decelerations will not be
79
Fetal stimulation
Can be performed simply by rubbing the crown of baby's head Done to elicit an acceleration in a fetus with minimal variability and no accelerations. If elicitable, this indicates a normal fetal blood pH and no further testing is required unless FHT changes further. If this fails, allis clamp stimulation or fetal scalp pH are indicated.
