Q

Preeclampsia Pathophysiology

A
  • differs from chronic hypertension (because NOT pregnant)
  • the main pathogenic factor is not an increase in BP but poor perfusion resulting from vasospasm
  • believed to be an interaction between cardiovascular and uteroplacental responses to pregnancy
  • caused by disruption in placental perfusion and endothelial cell dysfunction
  • arteriolar vasospasm diminishes the diameter of blood vessels, which impedes blood flow to all organs and increases BP
  • women who are pregnant have increased BV and more cardiac requirements, more effort. risk for vasospasm is higher

Q

Nursing Care Management Preeclampsia: Assessment

A

First Sign - Elevated BP
2nd Sign - Proteinuria
3 Questions: do you have a headache? Visual disturbance? RUQ epigastric pain?
Fetal health surveillance (nonstress test, contraception stress test, laboratory stress)
women get their BP check eery prenatal appointment. checked and cataloged, pee on the stick every visit is no longer used. it wasnt indicating it and most women produce ketones to some level in pregnancy. proteinuria has to be accompanied by other symptoms

Q

How to fix hypertensive disorders in pregnancy (HDP)

A

the only was to fix HDP is to delivery the baby and remove the placenta. The method of delivery will depend on severity and condition of fetal well-being

21
Q

Gestational Diabetes Mellitus

A
  • hyperglycemia that is first recognized in pregnancy
  • prevalence: 3.8-6.5%
  • higher among aboriginal, latin american, south asian, asian, and african women
    Maternal and fetal risks:
  • 2 times the risk of developing hypertensive disorders
  • uncontrolled GDM can impact fetus development (LGA)
22
Q

Risk factors for GDM

A
  • age, hx, obesity, polycystic ovarian syndrome
    Identify hyperglycemia early
23
Q

Interventions GDM: antepartum, intrapartum, postpartum

A

Antepartum:
- diet
- exercise
- monitoring blood glucose levels
- insulin therapy
- fetal surveillance
Intrapartum - monitor q1h, FHR, no glucose IV bolus
Postpartum - returns to N, reoccurs, risk of T2DM later

24
Q

Management of Infants of Mother with Diabetes

A

Critical to stabilize the newborn’s blood glucose
- in first two hours of life, even a healthy term newborn’s blood glucose falls
- early S2S & initiation of BF
- frequent BF
- blood sugar levels monitored as per protocol & intervention to maintain blood glucose in target range
- May be a medical indication of supplementation with expressed breast milk or if EBM not available, formula
Critical to ensure testing & feeds as per protocols
May need to be admitted to NICU for IV D10W

  • loss of consciousness
26
Q

Hyperemesis Gravidarum

A

Nausea and vomiting during pregnancy is the most common medical condition affecting 50-90% of women at some point in their pregnancy
- HG is protracted vomiting, retching, severe dehydration, and weight loss requiring hospitalization
- usually begins during the first 10 weeks of pregnancy

27
Q

Etiology of HG

A

not well understood, increased levels of Estrogen/ hCG, assoc. with transient hypothyroidism

28
Q

Clinical manifestations and assessment of HG

A
  • wt loss, dehydration, low BP, increased pulse, poor skin turgor
  • assessment: severity (freq, duration, diarrhea, wt. fluid/electrolytes, ketonuria, dehydration, CBC, psychosocial)
29
Q

Care of HG

A

Initial care: clear fluids to diet with protein, IV, antiemetics, I &O
Follow up care: small freq high protein/bland meals, Mg, K, decrease orders
- compassionate, sympatheticcare

30
Q

Hemorrhagic Disorders

A

hemorrhagic disorders in pregnancy are medical emergencies (hypovolemia)
- 50% of bleeding in the third trimester is placenta previa or placental abruption

31
Q

Early Pregnancy Bleeding

A

Miscarriage (spontaneous abortion)
Clinical manifestations: back pain, cramping, bleeding
- early pregnancy 1-6 weeks: heavy menstrual flow
- early pregnancy 6-12 weeks: mod discomfort, blood loss
- late pregnancy 12-20 weeks: age, parity, infection, cervical dilation

32
Q

Types of Miscarriage

A

Threatened: seems like a miscarriage might happen
Inevitable: started
Incomplete: something is retained
Complete: everything is out
Missed: woman who didnt know she had one

33
Q

Assessment of miscarriage

A

ultrasound, lab tests, infection, loss
- medical-surgical management (rest, supportive care, cs dilation, D&C)
- Nursing care - antibiotics, Transfusion, psychosocial care, & burial.
- Home care - iron supp, bleeding, sexual activity, family planning, support groups, F/U phone call, loss

34
Q

Premature Dilation of the Cervix

A
  • incompetent cervix, cervical insufficiency
  • passive and painless dilation of the cervix without contractions or labour
    Etiology - past trauma, D&C, short cervix
  • medical surgical management - conservative management of restricted activity and hydration. Prophylactic cerclage (24 weeks) - removed at 35-37 wks
    Nursing care - monitor for contractions, PROM, infection
    Home Care - decrease activity, bedrest, bleeding
    Cervix is not staying closed. no contractions. incompetent cervix.
35
Q

Ectopic Pregnancy: clinical manifestations

A

Fertilized ovum implanted outside uterine cavity
95% occur in uterine (fallopian) tube
Clinical manifestations: missed menstrual period. Abdominal pain. Mild-to-moderate dark red or brown intermittent vaginal bleeding occurs in up to 80% of women

36
Q

Nursing Care: Ectopic Pregnancy

A

Treatment options: salpingostomy (surgical opening of fallopian tube), salpingectomy: removal of fallopian tube
Hospital care: pre-op/post-op, V/S, discuss future fertility
Home care - loss & grief/infertility support groups
No ectopic pregnancies are viable. they will not grow past the trophoblastic phase. it is going to burst the fallopian tube which is lifethreatening for the woman and decrease her fertility

37
Q

Late Pregnancy Bleeding - Placenta Previa

A

placenta implanted in lower uterine segment near or over cervical os
classification based on degree of cervical os is covered by placenta
- complete placenta previa: covers internal cervical os completely
- marginal placental previa: 2.5 cm or closer to the cervical os
- low-lying placenta - no measurement of edge of placenta to cervical os
Diagnosis: transabdominal u/s exam, transvaginal u/s

38
Q

Risk factors, manifestations, fetal and maternal for placenta previa

A

Risk Factors: previous placenta previa, c/s, endometrial scarring
Clinical Manifestations: diagnosed by u/s, painless bright red vag. bleeding
Outcomes: hemorrhage, abnormal placental attachment, poor placental exchange, hysterectomy
- fetal risk: malpresentation, stillbirth, fetal anemia preterm birth

39
Q

Late Pregnancy Bleeding: Abruption

A

Premature separation of placenta
- grades: mild, moderate, severe
Clinical manifestations: partial or complete separation
- dark, vaginal non-clotting bleeding
- abdominal back pain
- port-wine stained amniotic fluid
- uterine contractions
- uterine tenderness
Maternal: hemorrage, hypovolemic shock, thrombocytopenia, renal failure
Fetus: abnormal FHR patterns, neurological defects, IUGR, death, > incidence of SIDS

40
Q

Infections Acquired During Pregnancy

A

Sexually transmitted infections: impact morbidity rates, infertility
UTI: responsible for 10% of hospitalizations
Asymptomatic bacteriuria: antibiotics, repeat urine culture
Cystitis (bladder infection) - dysuria, urgency, suprapubic pain, 3-day course of antibiotics which may stain urine orange
Pylenophritis - kidney stones. common, 2nd trimester, fever, chills, pain in lumbar area, N&V, admitted with IV antibiotics, monitor for sepsis, regular urine cultures

41
Q

Trauma During Pregnancy

A

Physical Trauma: MVA, falls, burns, violence
Effects of trauma on pregnancy is influenced by the following: length of gestation, type and severity of the trauma, degree of disruption of uterine and fetal physiological features - fetal death
Significance - 6-7% of pregnancies are complicated by physical trauma. accounts for 46% of maternal mortality, special considerations for mother and fetus: physiological alterations of pregnancy, fetal survival depends on maternal survival, pregnant woman must receive immediate stabilization and care for optimal fetal outcome
Fetal physiological characteristics
- careful monitoring of fetal status
- fetal monitor tracing works as an “oximeter” for fetal well-being

42
Q

Perimortem C/S

A
  • poor fetal survival with C/S > 20 min after maternal death
  • consider C/S after 4 minutes of resusc. with no response in the mother
  • rarely successful
43
Q

Postpartum Hemorrhage Definitions and Incidence

A

Leading cause of maternal death worldwide, preventable
Postpartum hemorrhage (PPH) traditionally defined as:
Loss of >500 mL of blood after vaginal birth
Loss of >1000 mL after Caesarean birth
Any blood loss that has the potential to cause hemodynamic instability
Among leading cause of maternal mortality worldwide
Life-threatening, with little warning
Early/ Primary – within 24 hrs of birth
Late/secondary - > 24 hrs – 6 weeks post birth
Due to retained placenta fragments /infection
Subinvolution of uterus (retained frag, pelvic infection)
Discharge teaching – signs of normal involution, complications

44
Q

Etiology of PPH - 4 Ts

A

Tone: Uterine atony - marked hypotonia of uterus, leading cause of early PPH
Trauma: lacerations of birth canal, uterine inversion, hematomas
Tissue: retained placental fragments, placenta acreta, increta, percreta
Thrombin: Various clotting disorders, correction of underlying cause

45
Q

Nursing Care Management PPH

A

Assessment: - early recognition is critical
1. Evaluation of contractility of uterus.
Firm massage of fundus
Administer intravenous fluids and medication to manage bleeding.
Active management of 3rd stage to prevent PPH
Oxytocin admin after delivery of fetal shoulder
Immediate fundal massage after complete birth

Plan of care and implementation
Hypotonic uterus – massage, elimination of bladder distention, IV
Bleeding with a contracted uterus (manual exploration of uterine cavity for placenta
Pharmacologic remedies – homeostatic actions or oxytocin agents

46
Q

Postpartum Infections

A

Peurperal infections: any infection of genital canal within 28 days after abortion or birth
- most common infecting agents are the numerous streptococcal and anaerobic organisms
- endometritis
- wound infections
- UTI
- mastitis

47
Q

Structural Disorders Related to Child-bearing

A
  • disorders of uterus and vagina related to pelvic relaxation and urinary incontinence are often the result of child-bearing
  • uterine displacement and prolapse
  • posterior displacement, or retroversion
  • uterine prolapse: more serious displacement
    Cystocele: protrusion of bladder downward into vagina when support structures are injured
    Rectocele: herniation of the anterior rectal wall through relaxed or ruptured vaginal fascia and rectovaginal septum
    Urinary incontinence
