(169 cards)
What is gestational hypertension?
o Gestational hypertension: Greater than 140/90 after 20 wks gestation
What is preeclampsia, risks ect..
o Preeclampsia: HTN and proteinuria
• Severe: htn (>160/110), proteinuria (>3+), low platelets, neurologic symptoms, oligouria (changes in kidney function), epigastric pain
• Risks: primigravida, multifetal, interval (10yrs), obesity, exposure to trophoblast tissue, preexisting medical/genetic conditions, extremes of age (40), poor outcome in previous pregnancy, family/personal hx, thrombophilias, periodontal disease
Nursing care for preeclampsia
- Nursing Care: assessments (hematocrit, platelet, liver function tests and 24hr urine for protein/week, 2x weekly= BP and urine protein, and BPP or NST at clinic. Daily FMC (normal 4/hr)
- Homecare: BP<500mg/day, normal platelet count, reassuring fetal status, no s/s or severe preeclampsia.
- If severe: drug of choice= magnesium sulfate
What is Eclampsia?
o Eclampsia: seizures or coma in preeclamptic woman
Nursing care for Eclampsia
• Nursing care: airway patent (turn to side, suction and 10L O2 via nonrebreather), observe and record convulsion activity, start IV fluids, give mag sulfate or other anticonvulsant, urinary cath, monitor BP, fetal and uterine status, lab work (kidney and liver function, coagulation system and drug levels. Provide hygiene and quiet environment, support and keep them informed. When stable assist with birth.
Magnesium sulfate action
o Action: Prevention of seizures (interferes with release of Ach at the synapses- depressing cardiac conduction and decreasing neuromuscular and CNS irritability)
Magnesium sulfate therapeutic level and dose
o Therapeutic Level: 4-7 mEq/l
o Dose: 4-6g over 15-30min, then 2g/hr
Side effects of magnesium sulfate
o Side effects: warm, flushed, diaphoresis, burning at IV site
Toxicity and antidote of magnesiam sulfate
o Toxicity:
• mild: lethargy, muscle weakness, decreased or absent DTR, dbl vision, slurred speech
• Worsening: bradycardia, bradypnea, hypotension, cardiac arrest
o Antidote: calcium gluconate or calcium chloride, and stop infusion
Nursing care for magnesium sulfate
o Nursing care: vitals q30min, monitor FHR and contractions. Monitor I&O, proteinuria, DTRs, presence of HA’s, visual disturbances, LOC, and epigastic pain hourly. UO at least 30ml/hr.
What is HELLP syndrome
Laboratory diagnosis for severe preeclampsia with hepatic dysfunction. Increased risk for adverse perinatal outcomes
Hemolysis, elevate liver enzymes, and low platelets
o Hydatidaform mole
- Incidence: 1 in 1000 pregnancies
- Signs and symptoms: Early stages can’t be distinguished from normal pregnancy. Later stage vaginal bleeding occurs (may be dark brown like prune juice or can be bright red) and ca be scant or profuse. Anemia, excessive n & v, and abdominal cramps/pain. Good chance show signs of preeclampsia.
- Treatment: Most abort spontaneously. If not suction curettage offers a safe and rapid method of removing mole. Post-evacuation admin of Rh (D) immune globulin to women who are Rh negative
Nursing care for Hydatidaform mole
• Nursing care: Nurse provides family with information about disease process and need of subsequent long course follow up and possible consequences of disease. Help family cope with pregnancy loss and recognize that this was not a normal pregnancy, encourage pt to express feelings (provide information about support groups) Explain the importance of postponing subsequent pregnancies.
• Late pregnancy bleeding : Placenta previa
o Placenta previa: Placenta is implanted in the lower uterine segment such that it completely or partially covers the cervix or is close enough to the cervix
• Incidence: 1 in 200 pregnancies (c/s, more than 35-40 years of age, multiparity, history of suction and curettage, and smoking)
• Signs and symptoms: Painless bright red vaginal bleeding during the 2nd or 3rd trimester. Initial bleeding is small and often forms clots (bleeding can reoccur at any time. Vital signs may be normal so a better indicator is urinary output. Abd exam is soft, relaxed, nontender uturus with normal tone. Fundal height is often greater than expected for gestational age. Breech and transverse presentation is common.
Late pregnancy bleeding: Abruptio placentae
o Abruptio placentae (placental abruption)
• Incidence: 1-75 to 1-226 (maternal hypertension, cocaine use, and abd trauma/ maternal battering, smokes, previous history, preterm PROM)
• Signs and symptoms: Vaginal bleeding (result in maternal hypovolemia so shock, oliguria, anuria), abd pain (mild to severe), uterine tenderness and contractions. Bleeding may be present through the vagina, may remain concealed, or both. If have c/s blood clots may be notes on entry to uterus. If a lot of bleeding has occurred the uterus will appears purple or blue and will have lost it contractility.
• What is a cerclage, why is it indicated and when is it placed?
o Cerclage is the use of a non-absorbable suture to keep a premature dilating cervix closed; released when pregnancy is at term.
o Is indicated for Incompetent cervix and is placed at 11-15 weeks of gestation and is removed at 37/when spontaneous labor begins.
• What are the normal physiologic changes that occur in the cardiovascular system related to pregnancy?
Increased cardiac output, HR and blood volume (plasma and RBC), slightly decreased BP
• Describe nursing care in the prenatal, labor, and postpartum periods for women with heart disease : Prenatal
• Prenatal:
o preconception care, limit stress on heart (greatest b/t 28 and 32 wks of gestation.
o Signs of decompensation: increased fatigue/difficulty breathing, feelings of smothering, cough, palpitations, generalized edema, irregular rapid pulse, lung crackles, orthopnea, rapid RR, cyanosis of lips and nailbeds.
o Infections treated promptly- b/c they can accelerate the HR and spread to heart structures.
o Nutrition counseling, avoid valsalva with BM (when released causes blood to rush to the heart and overload the cardiac system)
o Med management (cardiac meds, anticoagulants- monitor PT and INR)
o Tests for fetal well-being and placental sufficiency. Close medical supervision
• Describe nursing care in the prenatal, labor, and postpartum periods for women with heart disease : Intrapartum
• Intrapartum
o Calm environment (minimizes anxiety and promotes cardiac function). Head and shoulders elevated and resting on pillow, side-lying position
o Cardiac monitoring- EKG, BP, and O2, and FHR
o Antibiotics- penicillin prophylaxis, prevent bacterial endocarditis
o Open-glottis pushing
o Assist with 2nd stage (forceps or vacuum)- to decrease the length and workload of heart
o Epidural- provides better pain than narcotics and less hemodynamic alterations
• Describe nursing care in the prenatal, labor, and postpartum periods for women with heart disease: Postpartum
• Postpartum-
o Monitor for cardiac decompensation- HIGH RISK for 1st 48hrs
o Good nursing assessment (vitals, O2, lungs and heart sounds, edema, bleeding, uterus, UP, pain (esp chest), emotional state, dietary intake, mom-baby interaction)
o Longer hospital stay- close monitoring of vitals. Semi-fowlers or side lying- head and shoulders elevated.
o Progressive, gradual activity
o Lactation generally okay
• Thiazide diurectics may suppress lactation. And can cause neonatal diuresis that leads to dehydration.
o Increased risk of usual pp complications: thrombus, infection, anema.
o Increased risk of congenital heart disease in neonate if parent has one.
• What is the most critical time for possible decompensation related to heart disease?
1st 48hrs after birth are highest risk for decompensation d/t increased blood flow to heart, CO, blood volume. Decompensation= inability of heart to maintain sufficient cardiac output
What assessment should be performed on the laboring and postpartum woman with heart disease?
Routine assessments for all laboring women, and ABGs, pulmonary artery catheter may be inserted to monitor hemodynamic status, ECG monitoring and continuous BP and O2 and continuous fetal monitoring.
• How is CPR and foreign body airway obstruction care different for pregnant women (later in pregnancy).
Uterus should be displaced laterally for chest compressions (manually or towel under a hip), paddles of defib one rib interspace higher than usual. If CPR not effective in 5 min, c-birth if fetus viable.
In 2nd and 3rd tri- use chest thrusts rather than abdominal thrusts.
• What is the most common medical disorder of pregnancy?
Anemia
