OB Flashcards
What to do if a labor’s patient electronic fetal monitor detects increasing late decelerations?
reposition the woman and notify the physician
What is one purpose of ultrasound imaging during pregnancy?
to rule out fetal abnormalities
How many days are between conception and implantation?
7
How many days after does ovulation occur after the start of menstrual period?
14
Determine the first day of the last menstrual period (LMP), count backward 3 months, add 7 days, ( correct the year if needed)
Nagele’s rule
how many days does the fertilized ovum stays in the fallopian tube for before it implants in the uterine wall?
about 4 days
Hegar’s sign
When the uterus becomes globular in shape, softens and flexes easily over the cervix, is a probable sign of pregnancy
cervical softening due to increased vascularity, congestion and edema, is a probable sign of pregnancy
Goodell’s sign
Chadwick’s sign
the bluish discoloration of cervix, is a probable sign of pregnancy
The legal point of viability of the fetus is
22 weeks
10 weeks to 12 weeks gestation
Auscultation of fetal heart beat by Doppler or ultrasonic transmitter is done at
A normal fetal heart rate is between
120 and 160 beats per minute
Early amniocentesis is performed at?
sixteenth week of pregnancy
The presence of biochemical or chromosomal abnormalities such as fetal lung maturity and genetic studies
What is Amniocentesis is used to detect?
done to evaluate the response of the fetal heart rate to periods of fetal movement
non-stress test (NST)
Contraction stress test
used to induce uterine contraction
Hyperemesis Gravidarum
excessive and persistent vomiting during pregnancy resulting in dehydration and starvation
To minimize heartburn the pregnant woman should sit up for
30 minutes after eating
Seizures and coma are associated with an
Eclamptic condition
a symptom of pregnancy-induced hypertension and should be reported to health care provider
Blurred vision
Gestational diabetes
an abnormal glucose tolerance due to decreased effectiveness of insulin during the second and third trimesters
A normal fetal heart rate is between
120 and 160 heats/minute
A pregnant client with known cardiac problems should be observed for
dyspnea and increased heart rate
The four components of the birth process
“four P’s” are the powers, the passage, the passenger and the psyche
A fetoscope can be used to auscultate the fetal heart rate at
18 weeks of gestation
The purpose of Leopold’s maneuvers is to determine
presentation and position of the fetus
The woman with placentae previa is more likely than others to have
infection or hemorrhage after birth
Preeclampsia progresses to eclampsia when
convulsions (seizures) occur
A woman can continue having sexual intercourse through out her pregnancy as long as
she remains comfortable
definite signs of true labor
Progressive uterine contractions are the
Increase in (HCG) human chorionic gonodotropin in a woman blood and urine is
indicative of pregnancy
Urine test kit purchased at the pharmacy to test for pregnancy,
detects for the presence of HCG
Anesthesia such as epidural pain relief is administered during
the first stage
An analgesic drug should not be given until
the cervix is dilated to at least 4cm
Complication of an epidural block include
maternal hypotension
Maternal bradycardia is commonly seen in the first
six to ten days postpartum
The main disadvantage of home birth is
lack of emergency equipment
stimulates the secretion of milk from the mammary glands
Prolactin
The early sign of labor is
the passage of the mucus plug or a bloody show as the cervix ripens
The nurse caring for a client who is receiving oxytocin (Pitocin) should monitor the
fetal heart rate
The duration of contraction is measured
from the time the uterus begins to contract until it relaxes
Oxytocin produces uterine contractions, which can cause
fetal anoxia
neural tube defect
An elevated alpha-fetoprotein (AFP) level is consistent with
Self-care instruction for a pregnant woman to lessen backache should include
wearing low-heeled shoes
Patient teaching before an NST includes,
the patient should eat, empty bladder and lie in SIMS position
Painless vaginal bleeding, usually bright red is the main characteristics of
placenta previa
Loss of more than 500cc of blood at time of delivery or immediately thereafter indicates
postpartum hemorrhage
Progressive uterine contraction is the
definitive sign of true labor
Naloxone (Narcan)
An opoid antagonist used to counteract respiratory depression in the newborn is
The umbilical cord normally contains
two arteries and one vein
First day postpartum, the fundus should be found
firm at midline
