OB Emergencies Flashcards
(42 cards)
Name 4 maternal changes in pregnancy.
increased circulating blood by 50%
Decreased TV
BP decreases slightly in the second trimester.
HR increases by 10-20 beats per min.
anemia in pregnancy
Name 5 considerations in OB transport.
place in left lateral recumbent or place pillows on the right side to relive supine hypotension.
EKG
O2
Fetal monitoring
IV
The left lateral recumbent position can increase overall circulating volume by?
30-40%
On fundal height assessment where is the measurement taking place? and what does that tell you about the age of the fetus?
symphysis pubis to the ridge of the uterus.
tells us the gestational age in weeks.
so 20com is 20 weeks old.
Fetal lie indicated the baby’s spine in relation to the mother’s spine. T/F
True. Fetal lie/fetal position also referred to as baby’s position in the womb before labor establishes where the baby’s face is – toward the mother’s back or her belly. Fetal presentation actually tells you what part of the baby’s body will lead the way out of the birth canal. With this, one can determine the direction the baby’s head and feet are.
Describe fetal station.
-3 is a floating baby and +3 in a crowning baby
what is effacement?
Effacement is the thinning and shortening of the cervix. It happens at the end of pregnancy in preparation for childbirth. A pregnant person must be 100% effaced for a vaginal delivery.
What is the first stage of labor?
Begins with the onset of contractions and ends with complete dilation of the cervix 10cm
Complete dilation to birth is what stage of labor?
second stage of birth
Birth of the placenta is considered ______ stage of labor.
the third stage of labor.
what is considered bradycardia in FHR?
<120 beats for greater than 5-10 min
Causes of bradycardia include?
Cord compression
cord prolapse
Tetanic contraction
Epidural spinal anesthesia
maternal seizures
Vigorous examination
Tachycardia FHR is?
causes are?
> 160 for 5-10 min
Fetal hypoxia
Maternal fever
hyper thyroid
Anemia and premature.
what is the FHM strip?
Fetal heart rate (FHR) accelerations associated with fetal movements is considered a sign of fetal well-being. baby is just moving and increasing the heart rate for a short time. sometimes with the contractions.
What is the FHM strip?
Early deceleration is defined as a symmetrical deceleration that matches the contractions decrease and return of fetal heart rate (FHR) that is associated with a uterine contraction. not harmful, returns to baseline after contraction
Name this FHM strip
Variable decelerations are generally irregular variable decelerations“. I remember it because the dips in the fetal heart tones look like V’s. The v’s remind me that this is a “variable deceleration”. Variable decelerations are NOT good! Notice that every time mom has a contraction the baby’s heart rate majorly decreases. Remember a normal fetal heart rate is 110-160 bpms.
What causes variable decelerations
Cord compression ( harmful)
premature rupture of membrane
decreased amniotic fluid
What is this FRM strip
Causes ?
Late decelerations begin at or after the peak of a contraction smooth shallow dip remains down long after the contraction has ended. Very Bad
The causes are fetal hypoxia placenta disfunction
What is this FHM strip?
Sinusoidal waveform wavy non-reactive to contractions Very Bad c section required
Causes are fetal anemia or hypoxia
What is A tetanic contraction?
What is a A tetanic contraction is a sustained muscle contraction
Pre-mature labor usually occurs between __________ weeks.
Medications for Premature labor include?
20-37 weeks.
Corticosteroids to help with lungs and GI tract, Tocolytics to reduce contractions, Magsolfate for seizures, and antibiotics for infection
Blurry vision or double vision
Frequent and persistent headaches
Stomach and/or abdominal pain
Rapid weight gain
Nausea and/or vomiting
PIH no protein in the urine.
Proteinuria may be an indicator of____________
Pr eclampsia
What three medications are indicated for PIH
(IV) labetalol 20mg
hydralazine 5mg
nifedipine 10-30 mg PO
