OB Test 1 Flashcards
discuss common techniques used to assess fetal well-being
- Ultrasound
- Biophysical profile
- Nonstress Test
- Contraction Stress Test
- Aminocentesis
list and explain one noninvasive way to assess fatal well-being
external abdominal ultrasound: safe, noninvasive, painless procedure whereby an ultrasound transducer is moved over a client’s abdomen to obtain an image. More useful after the 1st trimester when the gravid uterus is larger.
discuss what to teach the pregnant client with heartburn; hemorrhoids; constipation
- Heartburn: Client should eat small frequent meals, not allow the stomach to get to empty or too full, sit up for 30 min after meals and check with provider prior to using OTC antacids
- Constipation: Encourage fluids, eat a diet high in fiber and exercise regularly
- Hemorrhoids: Warm sitz bath, witch hazel pads and application of topical ointments
how is the sex/gender of the baby determined
- DNA determines baby’s gender.
- XX- female
- XY- male
- Father determines baby’s gender.
discuss common maternal discomforts during pregnancy and their treatment
- nausea/vomiting: should eat crackers (dry food) 30min to 1 hour prior to getting up in the morning to prevent feelings.
- breast tenderness: client should wear a comfortable bra with room to breath.
- urinary frequency: client should void full and often. don’t drink right before bed. practice kegal exercises. wear pads.
- UTI: avoid bubble baths, wipe front to back, cotton panties, loose underwear/pants
- fatigue: simple solution –> rest often!
- constipation: eat fiber. drink plenty of fluids. exercise 30 minutes 3x/week.
discuss the signs and symptoms of hyperemesis gravidarum
- excessive vomiting/diarrhea
- dehydration
- weight loss
- increased pulse
- decreased BP
- poor skin turgor and dry mucous membranes
discuss the client teaching following a vasectomy
following the procedure:
- scrotal support and moderate activity for a couple of days to reduce discomfort
- sterility is delayed until the proximal portion of vas deferent is clears of all remaining sperm (approx. 20 ejaculations)
- follow up for a sperm count
- no lifting heavy objects
identify vital signs in the pregnant client that should be reported to the charge nurse or provider
dizziness, lightheadedness, and cool/clammy skin should be reported
discuss the use of basal body temperature method of birth control
temperature can drop slightly at the time of ovulation. this can be used to facilitate conception, or be used as a natural contraceptive.
woman is instructed to measure oral temperature before getting out of bed in the morning.
advantage: inexpensive, convenient, no s/e
disadvantages: BBT is influenced by many factors
risk: pregnancy

list the client instructions for taking oral contraceptives
requires a prescription and follow-up appt.
medication must be used consistently
if one dose is missed, take one pill immediately when remembered, then take next dose at scheduled time. If missing 2+ doses, see manufacturer’s instructions and use alternative form of contraceptive to prevent pregnancy.
what would the nurse expect to assess in the client who is 8 weeks? 12 weeks? 20 weeks?
8 weeks:
- At 5 weeks the embryo is ¼ inch long

chloasma: pigmentation increases on the face
striae gravidarum: stretch marks around abd., breasts, and thighs
define and describe hydatidiform mole
A hydatidiform mole is a growing mass of tissue inside your womb (uterus) that will not develop into a baby. It is the result of abnormal conception. It may cause bleeding in early pregnancy

12-16. 10 is danger
describe general function of each major organ of the male and female reproductive system
- Ovaries- produces eggs and sex hormones. Monthly prepares for a possible pregnancy by producing an ovum
- Fallopian tubes- Cilia sweep ovum into the fallopian tube; smooth contractions move ovum towards the uterus
- Uterus- If ovum is fertilized, implants in wall of uterus leading to pregnancy
- Cervix- Provides opening to uterus from vagina
- Vagina- Birth canal through which infant passes
- Testes/testicles- Sperm is produced
- Scrotum- Regulates temperature for sperm production
- Epididymis- Site where sperm are stored
- Vas deferens- Long tube that connects the epididymis to the urethra
- Penis- Deposits sperm in the female
discuss the purpose of non-stress test and explain how it’s done
Most widely used technique for antepartum evaluation of fetal well-being performed during the 3rd semester. It is a noninvasive procedure that monitors response of the FHR to fetal movement. A Doppler transducer and a tocotransducer (used to monitor uterine contractions) are attached externally to a client’s abd to obtain tracing strips. The client pushes a button attached to the monitor whenever she feels a fetal movement, which is then noted on the tracing. This allows a nurse to monitor the FHR in relationship to the fetal movement.
list 3 food sources for folic acid
leafy veggies
peas
seeds
when should the pregnant client first feel fetal movement
by the 16th week
give examples of primary, secondary, and tertiary prevention
Primary- Education, teaching abstinence, effective birth control measures
Secondary- Encourage client to use contraceptives consistently and to detect early pregnancy
Tertiary- Counsel client about available options such as keeping the baby, adoption and abortion
list the equipment needed to perform a biophysical profile

ex: last period of April 1, 2013 –> due date is January 8, 2014
explain the variables in the biophysical profile (BPP). How are the scores interpreted.
Assesses fetal well being by measuring the following 5 variables with a score of 2 for each normal finding and a score of 0 for each abnormal finding:

- Fetal breathing movements (at least 1 episode of greater than 30 seconds duration in 30 min)- 2; absent or less than 30 seconds duration- 0
- Gross body movements (at least 3 body or limb extensions with return to flexion in 30 minutes)- 2; less than 3- 0
- Fetal tone (at least 1 episode of extension with return to flexion)- 2; slow extension and flexion, lack of flexion or absent movement- 0
- Qualitative amniotic fluid volume (at least one pocket of fluid that measures at least 2 cm in two perpendicular planes)- 2; pockets absent or less than 2 cm- 0
