Q

Pregnancy: Physiological Changes

A

Cardiovascular System: blood volume increases, plasma increases, total RBC volume increases (40-50%); H&H levels decline due to increased plasma volume

  • A decreased hemoglobin to less than 10g/dL and/or a decreased hematocrit to less than 30% indicates anemia

Respiratory System: O2 consumption increases 15-20%, diaphragm is elevated

GI System: progesterone and decreased motility can cause consitpation

GU: urinary frequency usually occurs in 1st and 3rd trimesters

Endocrine System: basal metabolic rate increases

Skin: progesterone and estrogen levels trigger an increase in melanocyte-stimulating hormone which may increase pigmentation (e.g. striae, chloasma)

Renal: glycosuria is a common result of decreased renal threshold to glucose

    • Eat small, frequent meals; remain upraight for 30min after eating; drink milk btwn meals; avoid fatty and spicy foods
  • Ankle edema - results from vasodilation and venous stasis and increased venouspressure below the uterus
  • Varicose veins
  • Headaches
  • Hemorrhoids
  • Constipation
  • Backache
  • Leg cramps - result from an altered calcium-phosphorous balance and pressure of the uterus on nerves (or from fatigue)

42
Q

Pregnancy & Birth: Blood Type & Rh Factor

A

If client is Rh- and has a negative antibody screen, she will need repeat antibody screens and should receive RhoGAM at 28 weeks’ gestation.

43
Q

Pregnancy & Birth: Rubella Titer

A

♦ A negative titer (less that 1:8) indicates susceptibility to the rubella virus

♦ Rubella vaccine is NOT given during pregnancy - the live, attentuated virus may cross the placenta

♦ Rubella vaccine is administered postpartum prior to discharge

♦ Assess client for allergy or sensitivity to eggs (the vaccine is made from duck eggs)

44
Q

  • Fetal movements
  • Fetal tone
  • Amniotic fluid index
  • Fetal heart rate patterns via nonstress test
45
Q

Pregnancy: Tests

A

♦ alpha-Fetoprotein Screening: assess the quantity of fetal protein levels

  • abnormal levels are associated with open neural tube and abdominal wall defects (spina bifida, down syndrome)
  • done at 16-18wks gestation

♦ Chorionic Villus Sampling: for the detection of genetic abnormalities

  • done at 10-13wks gestation
  • Rh-negative women ay be given RhoGAM b/c of increased risk of Rh sensitization

♦ Amniocentesis: for the detection of genetic disorders, metabolic defects, and fetal lung maturity

  • Performed btwn 15-20wks gestation

** After chorionic villus sampling and amniocentesis, if the client experiences chills, fever, bleeding, leakage of fluid at the needle insertion site, decreased fetal movement, uterine contractions, or cramping, notify HCP immediately **

46
Q

Pregnancy: Kick Counts

A

♦ Notify HCP if there are fewer than 10 kicks in two consecutive 2-hour periods

47
Q

Pregnancy: Nonstress Test

A

♦ Performed to assess placental function and oxygenation

♦ Determines fetal well-being via fetal heart rate response to fetal movement

♦ “Reactive” = “normal,”healthy fetus

  • 2 or more FHR accelerations of at least 15bpm lasting at least 15sec in association with fetal movement in a 20min period

♦ “Nonreactive” = “abnormal”

  • No accelerations or acceleration less than 15bpm ar lasting less than 15sec during 40min observation

♦ “Unsatifactory”= results cannot be interpreted due to poor quality of FHR tracing

48
Q

Pregnancy: Contraction Stress Test

A

♦ Assesses placental oxygenation and function

♦ Determines fetal ability to tolerate labor and determines fetal well-being

♦ Fetus is exposed to stress of contractions to assess the adequacy of placental perfusion under simulated labor

♦ Performed if nonstress test is abnormal

♦ Procedure

  1. Baseline fetal monitoring of 30min
  2. Dilute dose of oxytocin is administered (or nipple stimulation) to produce 3 or more contractions in a 10min period
  3. Maternal blood pressure assessed frequently esp during increases in oxytocin administration

♦ Results

  • “Negative” = “Normal”
    • No late decelerations or signs of fetal distress
  • “Positive” = “Abnormal”
    • Presence of late decelrations w/ 50% of contractions in the absence of hyperstimulation of the uterus
  • “Equivocal” = decelerations present but with less than 50% of the contractions or uterine activity shows a hyperstimulated uterus (?)
  • “Unsatisfactory” = adequate uterine contractions cannot be achieved or the FHR is of insufficient quality
49
Q

Pregnancy & Lactation: Nutrition Basics

A

♦ Women of normal prepregnancy weight are expected to gain 25-35 lbs

♦ An increase of approx 300 calories a day is sufficient (calorie needs are greater in the 2nd and 3rd trimester)

♦ An increase of approx 500 calories is needed during active lactation

♦ A diet high in folic acid is necessary to prevent neural tube defects

♦ Pica = eating nonfood substances such as dirt, clay, starch, and freezer frost; cause is unknown

50
Q

Pregnancy Risk Conditions: Anemia

A

♦ Anemia predisposes the client to postpartum infection

Assessment
♦ Fatigue, headache, pallor, tachycardia
♦ Hemoglobin <10g/dL
♦ Hematocrit <30%

51
Q

Pregnancy Risk Conditions: Abortions

A

♦ Spontaneous – pregnancy ends due to natural causes

♦ Induced – therapeutic or elective reasons exist for terminating pregnancy

♦ Threatened – spotting and cramping without cervical change

♦ Inevitable – loss of some of the products of conception with part of the products retained (most often placenta)

♦ Complete – loss of all products of conception

♦ Missed – products of conception are retained in utero after fetal death

♦ Habitual – spontaneous abortions occur in three or more successive pregnancies

52
Q

Pregnancy Risk Conditions: Chorioamnionitis

A

♦ Bacterial infection of the amniotic cavity

♦ Newborn of a diabetic mother is at risk for:

  • hypoglycemia
  • hyperbilirubinemia
  • respiratory distress syndrome
  • hypocalcemia
  • congenital anomalies

♦ During 1st trimester, maternal insulin needs decrease

♦ During 2nd and 3rd trimesters, placental hormones may cause an insulin-resistent state requiring increases in insulin doses

♦ Immediately after placental delivery, insulin needs decrease

54
Q

Pregnancy Risk Conditions: Ectopic Pregnancy

A

♦ Implantation of the fertilized ovum outside of the uterine cavity (most commonly in the ampulla of fallopian tube)

♦ S/S:

  • missed menstrual period
  • abdominal pain

  • Laparotomy and removal of the pregnancy and tube (if necessary) or repair of the tube
55
Q

Pregnancy Risk Conditions: Hepatitis B

A

♦ Hepatitis B is transmitted through blood, saliva, vaginal secretions, semen, breast milk, and can cross the placenta

Labor & Delivery: Lie

A

♦ Relationship of the spine of the fetus to the spine of the mother

♦ Longitudinal or Vertical

  • Fetal spine is parallel to the mother’s spine
  • Fetus is in cephalic or breech presentation

♦ Transverse or Horizontal

  • Fetal spine is at a right angle or perpendicular to mother’s spine
  • Presenting part is the shoulder
  • Delivery by cesarean is necessary
65
Q

Labor & Delivery: Presentation

A

♦ Presentation is the portion of the fetus that enters the pelvic inlet first

  • Cephalic = head first
  • Breech = buttocks
  • Shoulder = transverse lie

♦ Presenting part is the specific fetal structure lying nearest to the cervix

66
Q

Labor & Delivery: Position

A

♦ Relationship of assigned area of the presenting part or landmark to the maternal pelvis

  • Occipito- = head first
  • Sacro- = butt first (breech)
  • Mento- = face first

♦ Directional designations are in relation to the baby’s spine

  • ROP = right occipitoposterior = the baby’s spine is facing the back of the mother’s body is angled to the R
  • ROA = right occipitoanterior = the baby’s spine is facing the front of the mother’s body and is angled to the R
  • See image for more positions
67
Q

Labor & Delivery: Station

A

♦ The measurement of the progress of descent in cm above or below the midplane from the presenting part to the ischial spine

♦ Station 0 – at ischial spine

♦ Minus station – above ischial spine

♦ Plus station – below ischial spine

68
Q

Labor & Delivery: Mechanisms of Labor

A

♦ Lightening (dropping, engagement) – occurs when the fetus descends into the pelvis about 2wks before delivery

♦ Other S/S

  • Increased Braxton Hicks
  • Vaginal discharge increases
  • Brownish or red-tinged cervical mucos is passed
  • Mother may have a sudden burst of energy (“nesting”) 24-48hrs prior to labor
  • Mother may lose 1-3 lbs due to fluid shifts
  • Spontaneous rupture of membranes

♦ False labor (prodromal labor) – contractions are felt in the abdomen and groin and are irregular (don’t progress)

♦ True labor – contractions are felt more in the back and are regular, stronger, and progress

69
Q

Labor & Delivery: Cardinal Movements

A

♦ Engagement

♦ Descent

♦ Flexion

♦ Internal Rotation

♦ Extension

♦ Restitution

♦ External Rotation

♦ Expulsion

70
Q

Labor & Delivery: Leopold’s Maneuvers

A

♦ Methods of palpitation to determine presentation and position of the fetus and aid in location of fetal heart sounds

♦ If the head is in the fundus, a hard, round, moveable object is felt

♦ If the buttocks are in the fundus, a soft, irregular, and difficult to move object can be felt

71
Q

Labor & Delivery: FHR Monitoring

A

♦ Accelerations – brief, temporary increases in FHR of at least 15bpm more than baseline and lasting at least 15sec; often associated with fetal movement

♦ Early decelerations – occur during contractions as the fetal head is pressed against the mother’s pelvis and return to baseline by the end of the contraction; not associated with fetal compromise and require no intervention

♦ Late decelerations – appear similar to early decelerations but occur well after the contraction begins and return to baseline after the contraction ends; related to uteroplacental insufficiency and require intervention

  • Change mother’s position
  • Administer O2

♦ Variable decelerations – caused by conditions that restrict flow through the umbilical cord; they do not have a uniform appearance fall and rise abruptly with the onset and relief of cord compression; require immediate intervention

  • Change mother’s position
  • Administer O2
  • Discontinue oxytocin
  • Asses vitals
  • Prepare to assest with amnioinfusion (instillation of warm saline to decrease cord compression)

♦ VEAL CHOP

Variable** C**ord compression

Early Head compression

Accelerations O2 (sufficient, good)

Late Placental utero insufficiency

72
Q

Labor & Delivery: Uterine Tone During Labor

A

♦ Uterus should relax between contractions for at least 60sec

♦ Resting tone (if measured with an interuterine pressure catheter, IUPC) should be 5-15mmHg

♦ Uterine tone during contractions may be 50-75mmHg and meay even reach up to 110mmHg while pushing in second stage

♦ Hypertonic uterine activity involves a resting tone that is too high during contractions and thus reduces uterine blood flow and decreases fetal oxygen supply

♦ Oxytocin is discontinued if uterine contraction frequency is less than 2min or duration is longer than 90sec or if fetal distress is noted
