Q

Pregnancy warning signs

A 
Vaginal bleeding
Increased/decreased fetal movement
HA or blurred vision
Swelling of hands and feet
Burning on urination
Abdominal or chest pains
Chills or fever 
Persistent vomiting 
Increase in fluid from the vagina
17
Q

Rh Incompatibility

A

Antigen-antibody reaction. Mother is Rh negative and baby is Rh positive. The maternal body forms antibodies when the baby blood is mixed. This is called sensitization. Treatment is RhoGAM

18
Q

Amniocentesis

A

Obtain amniotic fluid for genetic testing. Usually done between 15-17 weeks. Also done in the 3rd trimester of pregnancy for lung maturation. The quadruple screen is the most widely used test to screen for down syndrome, trisomy 18 and neural tube defects. Evaluation of fetal maturity.

19
Q

Risks of amniocentesis

A 
Pain
Contraction
Rupture of membranes
Fetal Injury 
Infection
Rh Isoimmunization
20
Q

Nursing care during amniocentesis

A

Give Rh immune globulin if Rh negative
Monitor vital signs
Observe for contractions, amniotic fluid leakage, bleeding or pain.

21
Q

Non stress test

A

Evaluates fetal well-being. Based on the knowledge that when the fetus has adequate oxygenation and an intact CNS there are accelerations of FHR with fetal movements. A reactive test is when there are 2 accelerations of at least 15bpm lasting at least 15 seconds in a 20 min period.

22
Q

Vaginal exam consists of

A

Dilatation (opening of cervix in cm)
Effacement (thinning/shortening of cervix %)
Station (+ or -)

23
Q

True labor

A

Contractions produce progressive dilatation and effacement of the cervix. They occur regularly and increase in frequency, duration and intensity. The discomfort of true labor contractions usually start in the back and radiates around to the abdomen. Pain is not relieved by ambulation, walking may intensify pain.

24
Q

False labor

A

Contractions DO NOT PRODUCE cervical effacement and dilatation. Irregular, do not increase in frequency, duration or intensity. May be perceived as a hardening w/o discomfort or discomfort mainly in the lower abdomen and groin. Discomfort is relieved by ambulation and changes in position, warm showers and drinking large amounts of water.

25
Q

Premature rupture of membranes (PROM)

A

Spontaneous rupture of membranes occurring before 37 weeks of gestation. Unknown cause but is associated with infection, previous hx of PROM, hydramnios, multiple pregnancies, UTI, amniocentesis, trauma, incompetent cervix, bleeding during pregnancy and maternal genital tract infection

26
Q

Premonitory signs of labor

A 
Lightening 
Braxton Hicks
Bloody show
Rupture of membranes 
Sudden burst of energy 
Weight loss
Diarrhea, N/V
Indigestion
