Reassuring the woman that spontaneous abortion usually results from an abnormality and that her actions did not cause the abortion.

Nursing management of the woman with a spontaneous abortion focuses on providing continued monitoring and psychological support. What is an important component of this support?

hCG level is monitored until it is undetectable to ensure that any residual trophoblastic tissue that forms the placenta is gone. Also, all Rh-negative unsensitized clients are given Rh immunoglobulin to prevent isoimmunization in future pregnancies.

Regardless of the ectopic pregnancy treatment approach what is monitored?

1.) Urine pregnancy test (confirm pregnancy) 2.) hCG levels (exclude false-negative) 3.) Transvaginal US (visualize misplaced pregnancy)

What diagnostic procedures are used when an ectopic pregnancy is suspected?

Transvaginal Ultrasound - done between 16 and 24 weeks' gestation to determine cervical length, evaluate for shortening, and attempt to predict an early preterm birth. Cervical shortening occurs from the internal os outward and can be viewed on ultrasound as funneling. Home Uterine Activity Monitoring -For a woman at risk for preterm birth, home uterine activity monitoring can be used to screen for pre-labor uterine contractility so that escalating contractility can be identified, allowing earlier intervention to prevent preterm birth.

What diagnostic tests may be performed to help determine if Cervical Insufficiency is an issue?

Vital signs can be within normal range, even with significant blood loss, because a pregnant woman can lose up to 40% of her total blood volume without showing signs of shock.

What does the nurse need to keep in mind concerning VS and placental abruptions.

Repeated second trimester losses

What is Cervical Insufficiency associated with?

The possibility of hemorrhaging during manual attempts to detach the placenta

What is a common risk of placenta accreta during the birthing process?

Determining and correct underlying cause of DIC Replacement therapy of the coagulation factors is achieved by transfusion of fresh-frozen plasma along with cryoprecipitate to maintain the circulating volume and provide oxygen to the cells of the body. Anticoagulant therapy (low-molecular-weight heparin), packed red cells, platelet concentrates, antithrombin concentrates, and nonclotting protein-containing volume expanders, such as plasma protein fraction or albumin, are also used to combat this serious condition.

What is done is a women develops DIC during abruptio placentae?

Painless, bright-red vaginal bleeding during the second or third trimester that is usually not profuse and ceases spontaneously, only to recur again. The first episode of bleeding occurs (on average) at 27 to 32 weeks' gestation. The bleeding is thought to continue due to the lower uterus not being able to contract adequately and stop the flow of blood from the open vessels.

What is the classic clinical presentation of placenta previa?

Chromosomal abnormalities

What is the likely cause of spontaneous abortion during the first trimester?

Maternal disease including: -cervical insufficiency -congenital or acquired anomaly of the uterine cavity (uterine septum or fibroids) -hypothyroidism -DM -chronic nephritis -use of crack cocaine -inherited and acquired thrombophilias -lupus -polycystic ovary syndrome -severe hypertension -acute infection such as rubella virus, cytomegalovirus, herpes simplex virus, bacterial vaginosis, and toxoplasmosis

This condition, also called premature dilation of the cervix, describes a weak, structurally defective cervix that spontaneously dilates in the absence of uterine contractions in the second trimester, or early third trimester, resulting in the loss of the pregnancy. Since this typically occurs in the fourth or fifth month of gestation before the point of fetal viability, the fetus dies unless the dilation can be arrested.

Prochlorperazine (Compazine)

This drug acts centrally to inhibit dopamine receptors in the CTZ and peripherally to block vagus nerve stimulation in the gastrointestinal tract. It is used to control severe nausea and vomiting.

PGE2, dinoprostone (Cervidil, Prepidil Gel, Prostin E2)

This drug stimulates uterine contractions, causing expulsion of uterine contents; to expel uterine contents in fetal death or missed abortion during second trimester, or to efface and dilate the cervix in pregnancy at term

Chronic HTN with superimposed preeclampsia

This type of HTN pregnancy problem occurs in approximately 20% of pregnant women with increased maternal and fetal morbidity rates.

TRUE

True or False: Choriocarcinoma is highly responsive to chemotherapy, with an overall remission rate greater than 90%

TRUE

True or False: DIC is usually associated with high mortality and morbidity rates.

TRUE

True or False: No single laboratory test is sensitive or specific enough to diagnose DIC definitively, but it can be diagnosed by using a combination of multiple clinical and laboratory tests that reflect the pathophysiology of the syndrome.

SOB (indicative of metastasis to the lungs)

Typically asymptomatic, the first symptoms of choriocarcinoma in 80% of cases include what symptoms?

1.) Hx 2nd-trimester pregnancy loss with painless dilatation 2.) Prior cerclage placement for cervical insufficiency 3.) Hx spontaneous preterm birth prior to 34 weeks' gestation 4.) Painless cervical dilatation on physical examination in the second trimester

What are ACOG recommendations concerning cervical cerclage?

Obstetric hemorrhage Need for blood transfusions Emergency hysterectomy Disseminated intravascular coagulopathy Renal failure.

What are the maternal risks of Abruptio Placentae

A neonatal intensive care team should be available during the birth process to assess and treat the newborn immediately for shock, blood loss, and hypoxia.

Because of the possibility of fetal blood loss through the placenta during abruptio placentae, what should be available during birth and why?

hCG level changes between days 0 and 4 after methotrexate therapy have clinical significance and predictive value. A decreasing beta-hCG level is highly predictive of treatment success

Beta-hCG monitoring is done following medical treatment of ectopic pregnancy. Note clinical significance of the results of said monitoring.

The separation is determined by if the bleeding occurs early or after 20 weeks of pregnancy.

Bleeding during pregnancy can be divided into two separate categories. What separates these categories?

• Bring gel to room temperature before administering. • Avoid contact with skin. • Use sterile technique to administer. • Keep client supine for 30 min after administering. • Document time of insertion and dosing intervals. • Remove insert with retrieval system after 12 hrs or at the onset of labor. • Explain purpose and expected response to client.

Concerning PGE2 or dinoprostone administration, what needs to be considered?

• Hx of vaginal bleeding and abdominal pain • Passage of tissue with subsequent decrease in pain and significant decrease in vaginal bleeding

Concerning a complete abortion, what findings may be seen?

• Hx of three or more consecutive spontaneous abortions • Not carrying the pregnancy to viability or term

Concerning a habitual abortion, what findings may be seen?

• Absent uterine contractions • Irregular spotting • Possible progression to inevitable abortion

Concerning a missed abortion, what findings may be seen?

• Presence of vaginal bleeding (often slight) early in a pregnancy. • No cervical dilation or change in cervical consistency. • Mild abdominal cramping. • Closed Cervical Os. • No passage of fetal tissue.

Concerning a threatened abortion, what findings may be seen?

• Intense abdominal cramping • Heavy vaginal bleeding • Cervical dilation

Concerning an incomplete abortion, what findings may be seen?

• Vaginal bleeding (greater than that associated with threatened abortion) • Rupture of membranes • Cervical dilation • Strong abdominal cramping • Possible passage of products of conception

Concerning an inevitable abortion, what findings may be seen?

There is no evidence that any antiemetic class is superior to another with respect to effectiveness.

Concerning antiemetic options for Hyperemesis Gravidarum, is there a preference concerning most effective.

--urinary retention --dizziness -hypotension --involuntary movements.

Concerning use of Promethazine (Phenergan) to treat Hyperemesis Gravidarum, for what adverse effects should the nurse look for?

Defined as BP exceeding 140/90 mm Hg before pregnancy or before 20 weeks' gestation. As our nation's obesity rate rises, more women will start pregnancies with elevated blood pressures. However, if maternal blood pressure exceeds 160/100 mm Hg, drug treatment is recommended

Describe Chronic HTN

Focuses on monitoring the woman very closely for signs of preterm labor: -backache -increase in vaginal discharge -ROM -uterine contractions

Describe the nursing management of Cervical Insufficiency.

The etiology of this condition is unknown; however, it has been proposed that abruption starts with degenerative changes in the small maternal blood vessels, resulting in blood clotting, degeneration of the decidua (uterine lining), and possible rupture of a vessel. Bleeding from the blood vessel forms a blood clot between the placenta and the uterine wall. The continued bleeding causes increased pressure behind the placenta and results in separation from the uterine wall

Describe the pathophysiology of Abruptio Placentae.

When the pressure of the expanding uterine contents becomes greater than the ability of the cervical sphincter to remain closed, the cervix suddenly relaxes, allowing effacement and dilation to proceed. The cervical dilation is typically rapid, relatively painless, and accompanied by minimal bleeding.

Describe the pathophysiology of Cervical Insufficiency

Minimal bleeding (<500mL) Marginal separation (10-20%) Tender Uterus No Coagulopathy No Signs of Shock No Fetal DistressMild (grade 1)

Describe the qualifications of Mild (grade 1) Abruptio Placentae

Moderate bleeding (1,000 to 1,500 mL), Moderate separation (20% to 50%) Continuous abdominal pain Mild shock Normal maternal blood pressure Maternal tachycardia

Describe the qualifications of Moderate (grade 2) Abruptio Placentae

Absent to moderate bleeding (more than 1,500 mL) Severe separation (more than 50%) Profound shock Dark vaginal bleeding Agonizing abdominal pain Decreased maternal blood pressure, Significant maternal tachycardia Development of DIC

Describe the qualifications of Severe (grade 3) Abruptio Placentae

Many women are asymptomatic before tubal rupture. The classic clinical triad of ectopic pregnancy includes abdominal pain, amenorrhea, and vaginal bleeding. Unfortunately, only about half of women present with all three symptoms.

Describe the symptomatic nature of ectopic pregnancy?

PP = soft and relaxed AP = firm to rigid

Describe the uterine tone associated with Placenta Previa and Abruptio Placentae.

During the first stage of vasospasm, BP increases causing a reduced blood flow to the brain, liver, kidneys, placenta, and lungs. As a result: --Liver function declines and subcapsular hemorrhage occurs causing epigastric pain and elevated liver enzymes -- Cerebral hemorrhage and symptoms of arterial vasospasm such as headaches, visual disturbances, blurred vision, and hyperactive DTRs. --A thromboxane/prostacyclin imbalance leads to increased thromboxane (a potent vasoconstrictor) and stimulator of platelet aggregation, and decrease prostacyclin (a potent vasodilator and inhibitor of platelet aggregation), which contribute to the HTN state. --GFR is reduced leading to reduced urine output and increased sodium, BUN, uric acid, and creatinine causing edema, both generalized and pulmonary. The second stage of preeclampsia is the woman's response to abnormal placentation, when symptoms appear, that is, hypertension, proteinuria, and edema due to hypoperfusion. Poor placental perfusion resulting from prolonged vasoconstriction helps to contribute to intrauterine growth restriction, premature separation of the placenta (abruptio placentae), persistent fetal hypoxia, and acidosis. In addition, hemoconcentration (resulting from decreased intravascular volume) causes increased blood viscosity and elevated hematocrit.

Describe what occurs during the two stages of pre-eclampsia.

1.) Bed rest at home in the lateral recumbent position 2.) Antepartal visits and diagnostic testing - such as CBC, clotting studies, liver enzymes, and platelet levels - increase in frequency. 3.) Self-monitor BP daily (every 4 to 6 hours while awake) and report any increased readings 4.) Measure the amount of protein found in urine using a dipstick and weigh self for any weight gain. 5.) Take daily fetal movement counts, and if there is any decrease in movement, she needs to be evaluated by her health care provider that day. 6.) Maintain balanced, nutritional diet with no sodium restriction 7.) Drink six to eight 8-oz glasses of water daily.

During pregnancy, what treatments may be enacted for a woman with mild elevations in BP?

At least three menstrual cycles to allow her reproductive tract to heal and the tissue to be repaired

For how long should a woman use contraceptives following ectopic pregnancy and why?

Pain Contractions Abdomen, noting any contractions, uterine tenderness, tenseness, or rigidity Changes in fetal movement and activity. Assess fetal heart rate and continue to monitor it electronically

For what should the nurse assess concerning Abruptio Placentae

--abnormal movements --neuroleptic malignant syndrome (seizures, hyper/hypotension, tachycardia, and dyspnea) --mental status --intake/output

For what should the nurse be alert when using Prochlorperazine (Compazine) to treat Hyperemesis Gravidarum?

Diarrhea Abdominal Pain Nausea Vomiting Dyspepsia Vaginal Bleeding Pain Fever Tachycardia Hypotension Anxiety

For what should the nurse monitor following administration of Misoprostol (Cytotec)?

1.) bed rest 2.) pelvic rest 3.) avoidance of heavy lifting 4.) progesterone supplementation in women at risk for preterm birth 5.) placement of a cervical pessary cervical cerclage procedure in the second trimester

How may cervical insufficiency be treated?

• Validation via client's history

How might a habitual abortion be diagnosed?

• US to identify products of conception in uterus

How might a missed abortion be diagnosed?

• Vaginal Ultrasound to confirm sac is empty • Declining maternal serum hCG and progesterone

How might a threatened abortion be diagnosed?

• US confirmation that products of conception still in uterus

How might an incomplete abortion be diagnosed?

• US and hCG levels to indicate pregnancy loss

How might an inevitable abortion be diagnosed?

Massive Hemorrhage Infertility Death

In ectopic pregnancy, the embryo enlarges and creates potential for organ rupture, as only the uterine cavity is equipped to expand and accommodate the fetal development. What could a rupture result in?

++diarrhea, constipation, abdominal pain, ++headache, dizziness, drowsiness, and fatigue. ++Monitor liver function studies as ordered.

In giving Ondansetron (Zofran) for Hyperemesis Gravidarum, for what should the nurse be on alert for?

When the woman exhibits no signs of renal or hepatic dysfunction or coagulopathy.

In mild preeclampsia, when are conservative strategies utilized?

++Institute safety measures to prevent injury secondary to sedative effects. ++Offer hard candy and frequent rinsing of mouth for dryness.

In treating Hyperemesis Gravidum with Promethazine (Phenergan), what can the nurse do to combat certain adverse/side effects?

Multiparous Cesarean birth in either a previous or the present pregnancy Abnormal placentation

Which women with placenta accreta are at highest risk for emergency hysterectomy?

A profuse hemorrhage may result because the uterus cannot contract to close off the open blood vessels.

Why is hemorrhage a common outcome with placenta accreta?

Methotrexate

With early diagnosis and lack of rupture, what can most women with ectopic pregnancy be treated with?

1.) Missed or incomplete abortion 2.) Vaginal Bleeding 3.) Small or normal size for date uterus

Women with a partial mole usually present with what clinical features?

Postpartum hypertension

Women with mild preeclampsia are at greatest risk for what? Prevention of disease progression is the focus of treatment during labor. Blood pressure is monitored frequently and a quiet environment is important to minimize the risk of stimulation and to promote rest. IV magnesium sulfate is infused to prevent any seizure activity, along with antihypertensives if blood pressure values begin to rise. Calcium gluconate is kept at the bedside in case the magnesium level becomes toxic. Continued close monitoring of neurologic status is warranted to detect any signs or symptoms of hypoxemia, impending seizure activity, or increased intracranial pressure. An indwelling urinary (Foley) catheter usually is inserted to allow for accurate measurement of urine output.
