NO
26
Teach pt with HTN who is managing it at home to report what?

28
what is given for seizure prevention?
magnesium sulfate
29
what is important about patients receiving magnesium sulfate?
should not be left alone!
30
what to do during convulsion/seizure?
Maintain patent airway​ Call for help – do not leave bedside​ Protect from injury if possible​ Observe and record activity/timing
31
aside from IVs, what might I probably be inserting in eclampsia pt?
urinary catheter for accurate I&Os
32
what might happen during a seizure that I would want to check after?
if membranes ruptured, and signs of placental abruption
33
why do we want good control of blood sugars before conception?
risk of miscarriage and complications with fetus
34
what kind of medication puts someone at risk for GDM?
corticosteroids
35
if non=fasting glucose (routine) is 11.5 mmol/L, will pt need to do second test?
no, this is enough to dx them with GDM

40
_____% of bleeding in the 3rd trimester is placenta previa or abruption
50
41
lab tests for miscarriage:
serum BhCG x2 over 48 hrs, CBC prn based on symptoms,, blood type and screen
42
this can lead to recurrent preterm births
premature dilation of the cervix
43
what is placenta previa?
Placenta implants in lower uterine segment near or over the internal cervical os
44
what is a marginal placenta previa?
when placenta has formed low in the uterus, no overlap seen, unknown relationship to cervix
45
risk factors for palcenta previa?
-previous PP -previous c section - suction curettage - multiparity - smoking - 35 + age - living at higher altitude (lower 02 levels = bigger placenta)

pre-E
59
a patient has antiphospholipid antibody syndrome. what are they at risk for?
