OB Flashcards
A condition in which the mothers’ pelvis is too small for the
baby to pass through.
CPD (contracted pelvis)
Hormone of pregnancy
Progesterone
Hormone for breast growth and other female characteristics
Estrogen
Follicular phase (number of days) in a menstrual cycle
1-14 days
Level of fundus at 12 weeks
Symphysis pubis
Level of fundus at 20 weeks
Umbilicus
Number of weeks to accurately determine age of gestation
22 weeks
Amount of normal amniotic fluid
500 ml-1, 000ml
Oligohydramios
Amniotic fluid less than 0.5 L between 32-36 weeks
Related to fetal problems such as obstruction in the
urinary tract, IUGR, any condition that prevents the
formation of urine or the entry of urine in to amniotic
sac results in oligohydramios.
Polyhydramios
Amniotic fluid greater 2,000 ml between 32-36
weeks. It is associated with maternal diabetes (Type
or Type II, multiple gestation, CNS anomalies and
iso-immunization.
Purpose of amniotic fluid
- Protects the fetus from a direct blow.
- Provides an environment so that fetus could
move and promoting grown and development. - Maintaining constant body temperature and
prevents heat loss.
Normal fetal heart rate (FHT)
120-160 beats per minute
Fetal heart tones heard thru fetoscope
By 20 weeks of gestation
Fetal heart tone that is bradycardic is
Less than110 beats per minute
Fetal heart tones that is tachycardic is
Greater than 160 beats per minute
Polyhydramios
Amniotic fluid exceeds 2,000 ml between 32-36
weeks. It is associated with maternal diabetes (Type
or Type II, multiple gestation, CNS anomalies and
iso-immunization
Normal characteristics of Amniotic fluid
Clear to stra0colored and no foul odor
PH ranges from neutral to slightly alkaline
Fetal stool is called
Meconium
Uterine infections are caused by.
HIV, Hepatitis A and B, Syphilis
not due to bacterial infection
Are decreases in the FHR baseline, can be abrupt or gradual.
Decelerations
Drug used to manage eclamptic seizure
Magnesium Sulfate
Frequency of Magnesium level monitoring
Every 4-6 hours
Used as anticonvulsant by reducing muscle excitability, and hyperreflexia
Magnesium Sulfate
Nurse alert prior to administering magnesium Sulfate
Patellar reflex, urine output, and respiratory rate
Antidote of Magnesium overdose
Calcium Gluconate 1 gram over 3 minutes IVP, may
be repeated every 4 hours as needed up to 8
injections in 24 hours.
Drug of choice of hypertension near term or during labor
Hydralazine(Apresoline)
Ferning pattern
Positive test result for ruptured membranes
Nitrazine test result would reveal (color and pH)?
Blue-green color, a pH Of 6.5 (not definitive)
Nitrazine paper will change to yellow color
Negative for amniotic fluid
Maybe indicative of infected amniotic fluid
Foul-smelling
If RhoGam is not given to a mother with Rh-, it may cause
Erythroblastosis Fetalis
RhoGam is administered within 72 hours after delivery
To protect the next pregnancy or miscarriage.
Purpose of RhoGam
To prevent maternal production of blood antibodies.
Pitocin drip should be stopped when contractions lasting for?
Over 90 seconds or a resting phase of less than 30
seconds or 60 seconds is acceptable between
contractions.
SIADH effective treatment
Decrease specific gravity of urine
PH of urine of 6.5
Probably membranes are ruptured
Severity of hyperemesis gravidarum what to assess
Check for glucose level
Insulin requirement of patient with infection
Increased insulin need
Magnesium Sulfate should never be administered in the
absence of?
Patellar reflex
Reverses the effect of opiods
Narcan (Naloxone), administer slowly to prevent
seizures and severe pain
Effect of epidural anesthesia to mother.
Maternal hypotension and urinary retention.
Intake should be monitored and limit to prevent
Pulmonary edema
Major cause of uterine atony
Due to a full bladder
Nursing responsibility bore administering Methylergonovine
TO check blood pressure before giving to client.
Use of Methylergonovine
Use to prevent or control post partum hemorrhage.
Hemolysis, Elevated Liver enzymes, Low Platelet count
HELLP
Platelet count is less than 100,000/mm3
Hypoglycemia may be present in client with HELLP.
An outcome of Rh incompatibility
Erythroblastosis fetalis
Hydroxyzine (Vistaril) is limitedly administered via
2-3 days
Intramuscular injection using -track technique
First fetal movement felt by number of weeks of gestation by
multiparas
Quickening by 16-18 weeks of gestation
First fetal movement felt by number of weeks of gestation by
primigravidas
Quickening by 18-20 weeks of gestation
Reduces neural defects such as spina bifida.
Folic acid
Foods to avoid by mother while breastfeeding.
Gas forming such as cabbage, broccoli, and onions
Assessment technique to look for the fetal lie, position, and
presentation
Leopoid’s maneuver
Iron is best taken
After meals daily, treatment usually for 2nd-3rd
trimestral of pregnancy.
SE: Constipation or diarrhea to others, abdominal discomforts.
Being experienced by mother and it is due to a rapid hormonal
shift about 2-7 days after delivery.
Post partum blues
Iron can be administered orally, intramuscularly, and I.V.
iron supplements are:
Monitor hypotension for IV administration.
Feosol, Slow Fe, Feratab, Slow FE, Fer-In-Sol
Oral contraceptives predisposes to?
Prone
Candidiasis
