Q

Missed Miscarriage

Complication if allowed to expel POC naturally

A

Infection (endometritis, sepsis)
- RPOC whether fetal or placental can be a source of infection
- Necrotic tissues trigger inflammatory response which activates coagulation system to DIC

# Incomplete Miscarriage Assessment
Part of the conceptus (usually the fetus) is expelled leaving the placenta or membranes retained in the uterus.
26
# Incomplete Miscarriage Procedures
**D&C** or **Suction Curettage** : to evacuate the retained tissues.
27
# Incomplete Miscarriage Patient Education
Tell the patient that pregnacy was already lost. She might be confused of the term "Incomplete"
28
# Incomplete Miscarriage Danger
Maternal Hemorrhage
29
POC entirely expelled and cervix is open
Complete Miscarriage
30
# Complete Miscarriage Symptoms
- Vaginal bleeding - Uterine Contractions - Cervical dilation
31
# Complete Miscarriage Assessment
**Bleeding and Cramping** - Bleeding stops after all POC are expelled spontaneously without assictance.
32
# Complete Miscarriage Procedure/Therapy
**None** - If heavy bleeding occurs, women needs to see HC provider
33
This refers to 3 or more spontaneous miscarriages in a row
Recurrent Miscarriage
34
Possible Cases of Recurrent Miscarriage
1) **Abnormal fetal development** either due to teratogenic factors 2) **Genetic factors** : defect sperm or egg / chromosomal abernations 3) **Anatomical Abnormalities of the uterus** : septate, bicornuiate; presence of fibroids ,leiomyomas 4) **Uterine infection** 5) **Autoimmune disorders** : rejection of fetal cells. 6) **Implantation abnormalities** : tubal implantation 7) **Endocrine Factors**
35
Refers to an insufficient production of progesterone or inadequare response of the endometrial lining to the progesterone produced which can lead to inability of the endometrium to sustain the pregnancy.
Luteal Phase Defect
36
Complications of Miscarriages
**1) Hemorrhage** : bleeding is not managed early. 2) **Infection** : d/t retained placental fragments. 3) **Septic Abortion** : r/t induced or illegal abortios done by untrained practitioner using non-sterile instruments 4) **DIC** : r/t missed abortion: necrotic tissue > inflammatary response > activate coagulation system. 5) **Rh Incompatibility / Hemolytic Disease of the Newborn** 6) **Powerlessness** : lack of control, helplesness
37
Describes another surface protein on the RBC. Named after the Rhesus monkey, where it was initially identified
Rh Factor
37
What happens in 1st pregnancy with Rh(+) fetus (under normal conditions | Mother is Rh (-)
- No mixing of blood; placenta serves as a barrier between maternal & fetal circulation - No antibodies produced by mother's immune system - No Rh incompatibility tissue/
38
What happens to a 1st pregnancy Rh- mother during delivery of an Rh+ baby?
- Placenta detaches from the uterine wall, fetal blood vessels in the placenta **may rupture**, allowing **Rh+ blood cells** from the fetus to **enter the maternal bloodstream.** - Mother produces antibodies against the "foreign" Rh+ blood **(initial sensitization & memory)** - Baby not affected since baby is already out
39
What happens during 2nd pregnancy of an Rh- mother to a Rh+fetus?
- **Mother's immune system is already sensitized** (produced antibodies & remembers the Rh antigen) making it capable of reacting more rapidly and aggressively to Rh+ cells of the fetus. - **Pre-existing antibodies** cross the placenta and**attack the fetal RBC** causing hemolysis
40
What happens in Hemolytic Disease of the Newborn (HDN)
Breakdown of RBCs > releaseof hemoglobin > heme > bilivergin > bilirubin > jaundice
41
Nursing Responsibilities for Rh Incompatibility
- **RhoGAM **(Brand Name) - **RhIG** Rh Immune Globulin (Generic Name)
42
Route of RhoGAM
Via IM to Rh- mothers to prevent Rh incompatibility
43
Standard administration schedule of RhoGAM
- Routine administation at **28 weeks gestation** (prophylaxis) - Within **72 hours after delivery**
44
Why give RhoGAM at 28 weeks gestation as prophylaxis?
This **prevents maternal sensitization during the third trimester**, when small amounts of fetal blood may enter the maternal circulation
45
Why give RhoGAM 72 hrs after delivery?
If newborn is Rh+, RhoGAM is given to prevent the mother from developing anti-D antibodies for future pregnancies
46
Nursing Responsibilities for Spontaneous Abortion
1) Assess and Monitor the Patient 2) Provide Emotional and Psychological Support 3) Prepare patient for possible procedures 4) Adminster IV fluids as ordered to maintain hemodynamic stability 5) Administer prescribed medications 6) Prevent and monitor for complications 7) Educate the Patient and Family 8) Educate about Emotional Recovery 9) Discuss contraceptive options if the patient wants to delay future pregnancies.
47
What to assess and monitor in patients with spontaneous abortion?
- Vital signs - signs of shock or infection (fever, chills, foul-smelling vaginal discharge) - presence of clots & frequency - Bleeding ( amount, color, presence of clots/tissue) - Evaluate pain (location, intensity, characteristics
48
When is Dilation and Curettage done?
If miscarriage is incomplete, for 1st tri miscarriage
49
When is Dilation & Evacuation done?
For 2nd tri miscarriages when pregnancy tissue is larger and requires more extensive removal.
50
This procedure is chosen when the body is allowed to **naturally expel** the pregnancy tissue withouth medical or surgical intervention
Expectant Management
51
This procedure uses a suction device instead of a sharp curet to remove pregnancy tissue. Done in early pregnancy (Less than or equal to 10-12 weeks)
Manual Vacuum Aspiration
52
Prescribed medications used for spontaneous miscarriages
1) **Oxytocin** - to contract the uterus & prevent hemorrhage. 2) **Misoprostol** - expel retained products if needed. 3) **Analgesics** - for pain relief
53

B. 20 weeks
54
Which term is preferred to avoid confusion with intentional termination of pregnancy? A. Abortion B. Miscarriage C. Stillbirth D. Ectopic pregnancy
B.Miscarriage
55
What is the primary cause of a luteal phase defect? A. Excess estrogen production B. Insufficient progesterone production C. High levels of hCG D. Overproduction of FSH
B. Insufficient progesterone production

b) " I will maintain strict bed rest for the remainder of the pregnancy"
