fertilization of an egg where the nucleus has been lost or inactivated. It contains no fetus, placenta, amniotic membranes, or fluid. Maternal blood has no placenta to receive it, so bleeding occurs · Ovum has no genetic material or material is inactive. Genetic material is all paternally derived · 20% will progress to choriocarcinoma

Hydatidiform Mole (Molar Pregnancy) · Gestational Trophoblastic Disease = Hydatidiform Mole and Choriocarcinoma (Cancer). These are groups of pregnancy-related trophoblastic proliferative disorders without a viable fetus that are caused by abnormal fertilization. · Hydatidiform Mole (molar pregnancy): Benign proliferative growth of the placental trophoblast, in which chorionic villi develop into edematous, cystic, avascular vesicles in a grape-like cluster.

Abruptio Placentae (Placental Abruption)

Nursing Considerations for Trauma: § Assess mother first. Baby cannot live if mom doesn't live, so make sure she is stabilized, then assess baby. § CABDs: compressions, airway, breathing, defibrillation · Avoid hyperextension of the neck. Use the jaw through to establish airway · Give O2 nonrebreather 10L/min § 2 IVs started to infused crystalloids (LR or NS) at 3mL of fluid per 1mL of blood volume lost. · Avoid giving vasopressors because they reduce uterine bloodflow § Risk of aspiration if unconscious and head is lower than ABD · Elevate head if possible!!!! § Avoid supine position, even with cervical injury due to risk of decreased CO and vena cava compression. But uterine displacement must occur without any head movement. As soon as the neck is mobilized, the stretcher should be tilted laterally § For CPR, if mom is more than 20 weeks gestation (fundus at level of umbilicus), displace hips when doing compressions (100-120/min). Place defibrillator pads one rib interspace higher than usual because the heart is displaced by uterus § Second Survey: after resuscitation and stabilization, check on mom and fetus (include assessment of all body systems) · Assess for ______________________: 1. Uterine tenderness/ pain 2. Uterine irritability 3. Vaginal bleeding 4. Leaking of amniotic fluid 5. Assess fetus, fetal heart tones

mother first. Baby cannot live if mom doesn't live, so make sure she is stabilized, then assess baby.

· Trauma During Pregnancy - Nursing Considerations for Trauma: § Assess __________________________________ § CABDs: compressions, airway, breathing, defibrillation · Avoid hyperextension of the neck. Use the jaw through to establish airway · Give O2 nonrebreather 10L/min § 2 IVs started to infused crystalloids (LR or NS) at 3mL of fluid per 1mL of blood volume lost. · Avoid giving vasopressors because they reduce uterine bloodflow § Risk of aspiration if unconscious and head is lower than ABD · Elevate head if possible!!!! § Avoid supine position, even with cervical injury due to risk of decreased CO and vena cava compression. But uterine displacement must occur without any head movement. As soon as the neck is mobilized, the stretcher should be tilted laterally § For CPR, if mom is more than 20 weeks gestation (fundus at level of umbilicus), displace hips when doing compressions (100-120/min). Place defibrillator pads one rib interspace higher than usual because the heart is displaced by uterus § Second Survey: after resuscitation and stabilization, check on mom and fetus (include assessment of all body systems) · Assess for placental abruption: 1. Uterine tenderness/ pain 2. Uterine irritability 3. Vaginal bleeding 4. Leaking of amniotic fluid 5. Assess fetus, fetal heart tones

DOMESTIC VIOLENCE

· Trauma During Pregnancy § Most trauma is from motor vehicle accidents (wear seatbelt) and falls, but other trauma results from partner violence, assaults, and suicide attempts § Trauma is the leading cause of non-obstetric maternal death in the U.S. § INCREASED INCIDENCE OF _______________________________! § Blunt Trauma: MVAs, falls, battering; blunt trauma to ABD can cause: · placental abruption (uterine pain, uterine irritability, contractions, vaginal bleeding, leaking amniotic fluid, change in FHR) · pelvic fracture · direct fetal injury · uterine rupture (rare) § Penetrating Trauma: bullet or stab wounds; when uterus is penetrated, fetus is more likely that mother to be seriously injured. § Thoracic Trauma: pulmonary contusion, pneumothorax, hemothorax

Prepare for emergency cesarean, but may deliver vaginally, very rapid labor.

· Treatment of Abruptio Placentae (Placental Abruption): § Nursing assessment is critical! · Pain · Amount of bleeding · Fetal status - EFM immediately for FHR · Uterine tone/tenderness and fundal height § Labs · H&H · Coagulation factors decreased · Type and cross § TIME CRITICAL! _______________________________________________________ · If fetus is between 20 and 34 weeks gestation, some doctors use expectant management, close monitoring, and fetal assessments § Immediate birth is used for term gestation or if bleeding is moderate-severe (mom and baby in jeopardy) · Initiate continuous electronic FHR monitoring and urinary catheter · IV fluids, blood, meds as prescribed · O2 8-10L/min via facemask · Monitor maternal vitals, observe for declining hemodynamic status · Assess urinary output and fluid balance § Provide emotional support for mom/family

hCG measured weekly until level decreases to normal for 3 weeks and then monthly measurements for 6-12 months

· Treatment of Hydatidiform Mole (molar pregnancy): § Suction & curettage to evacuate tissue from the uterus. Give Rh immune globulin after procedure to Rh negative clients § After procedure, client should have a baseline pelvic exam and ABD ultrasound § Serum ___________________________________________________________ § Avoid pregnancy until cleared after follow-up visits. This avoids confusion in regard to rising hCG which could indicate either normal pregnancy or GTD § Use any contraceptive method (oral contraceptives) except IUD § Older women may prefer a total hysterectomy for sterilization § Nursing Care: fundal height measurement, assess vaginal bleeding, GI status, provide support

Gestational Hypertension

· _______________________________________ is the onset of hypertension (Defined as BP >140/90 mm/Hg) without proteinuria or other systemic findings after week 20 of pregnancy in a woman with a previously normal blood pressure. It does not persist longer than 12 weeks postpartum (usually resolves in 1st week after birth) § Blood pressure should be recorded after week 20 of pregnancy on 2 separate occasions at least 4-6 hours apart, but within a week. § S/S: severe continuous headache, nausea, blurred vision, flashes of light/dots in eyes · Only one of the pressures; either systolic or diastolic needs to meet the criteria to confirm the diagnosis § Mild >140/90 § Severe >160/110 · NO PROTEINURIA.

Disseminated Intravascular Coagulation (DIC)

·________________________: Consumptive coagulopathy; a pathologic form of clotting that is diffuse and consumes large amounts of clotting factors, resulting in widespread external/internal bleeding and clotting § It is a secondary diagnosis to some other problem that triggered the clotting cascade: · Placental abruption · Retained Dead Fetus Syndrome · Amniotic fluid embolus · Severe preeclampsia · HELLP syndrome · Sepsis
