Q

Implantation of the blastocyst:

A

The embedding of the blastocyst( composed of an inner cell mass known as the embryoblast, which will develop into the embryo) into the endometrium of the uterus, begins around day 5 or 5.

Q

What is the opening in the heart between the right and left atria:

A

The foramen ovale; Oxygenated blood is shunted to the left atrium via the foramen ovale. After birth it closes in response to increased blood returning to the left atrium. This can take up to 3 months to fully close.

Q

Ductus Arteriosus:

A

Connect the pulmonary artery with the descending aorta. The majority of the oxygenated blood is shunted to the aorta via the ductus arteriosus with smaller amounts going to the lungs. After delivery, the ductus arteriosus constricts in response to the higher blood oxygen levels and prostaglandins.

Q

Metabolic and gas exchange:

A

In the placenta, fetal waste products and CO2 are transferred from the fetal blood into the maternal blood sinuses by diffusion. Nutrients, such as glucose and amino acids, and O2 are transferred from the maternal blood sinuses to the fetal blood through the mechanisms of diffuse and active transport.

Q

What does hCG do:

A

hCG stimulates the corpus luteum so that it will continue to secrete estrogen and progesterone until the placenta is mature enough to secrete these hormones. This is the hormone assessed in pregnancy tests. hCG rises rapidly during the first trimester and then has a rapid decline.

Q

The endometrial cycle pertains to the changes in the endometrium of the uterus in responses to hormonal changes that occur during ovarian cycle. There are 3 phases:

A

Poliferative phase: Occurs following menstruation and ends with ovulation
Secretory phase: begins after ovulation and ends with onset of menstruation. the endometrium thickens. The primary hormone during this phase is progesterone which is secreted from the corpus luteum.
Menstrual phase: Occurs in response to hormonal changes and results in sloughing offof the endometrial tissue.

Q

What is uterine atony?

A

A decreased tone of the uterine muscle which is the major cause of primary PPPH. Uterine contractions constrict the open vessels at the placental site and assist in decreasing the amount of blood loss. When uterus relaxes, the vessels are less constricted and the woman experiences an increase of blood loss.

64
Q

Assessment findings in PPH:

A 
Soft (boggy) fundus versus firm fundus
Saturation of the peripad with 15 minutes
Bleeding is slow and steady or sudden and massive 
Blood clots may be present 
Pale color and clammy skin 
anxiety and confusion 
Tachycardia 
Hypotension
65
Q

Medication - Methergine:

A

Indication: PPH due to uterine atony or subinvolution.
Action: Stimulates contraction of the uterine smooth muscle
Common side effects: Nausea, vomiting, and cramps.

66
Q

Medication - hemabate

A

Indication: PPH that has not responded to oxytocin or methylergonovine therapy.
Action: Uterine contractions
Common side effects: Diarrhea, nausea, vomiting, and fever

67
Q

DIC:

A

Disseminated intravascular coagulation: is a syndrome in which the coagulation pathways are hyperstimulated. When this occurs, the woman’s body breaks down blood clots faster than it can form them, thus quickly depleting the body of clotting factors and leading to hemorrhage and death.

68
Q

Assessment finding in DIC

A

Prolonged, uncontrolled uterine bleeding
Bleeding from the IV site, incision site, gums, and bladder
Purpuric areas at pressure sites, such as blood pressure cuff site
Abnormal clotting study results, such as platelets platelets and activated partial thromboplastin time (PPT)

69
Q

Nursing Actions of DIC:

A

Reduce risk of DIC:
Review prenatal and labor records for risks factors
Monitor women more frequently who are at risk for DIC.
Assess for PPH and intervene appropriately. Early intervention can decrease the risk of DIC.
Monitor vital signs and immediately report to the MD or CNM abnormal findings, such as an increase in heart rate, a decrease in blood pressure, and a change in quality of respirations.
Obtain IV site with large-bore intracatheter as per orders.
Administer Iv fluids as per orders
Administer oxygen as per orders
Obtain laboratory specimens as per orders.
Review laboratory results and notify the physician of results
Start a blood transfusion as per orders.
Provide emotional support and information to the woman and her family to decrease level of anxiety.
Facilitate transfer to intensive care unit.

70

71
Q

Eclampsia:

A

The onset of convulsions or seizures that cannot be attributed to other causes in a woman with preeclampsia.

72
Q

Preeclampsia:

A

Is a hypertensive, multisystem disorder of pregnancy whose etiology remains unknown. Preeclampsia is the best described as a pregnancy-specific syndrome of reduced organ perfusion secondary to vasospasm and endothelial activation. Delivery is the only cure.

73
Q

HELLP:

A

Hemolysis, Elevated Liver enzymes, and Low Platelets.

74
Q

Preeclampsia assessment Findings:

A

Elevated blood pressure: hypertension with systolic pressure 140mmHg or greater and diastolic pressure 90 mm Hg or greater.
Proteinuria is 1+ or greater.
Lab values many indicate elevations in liver function tests, diminished kidney function, and altered coagulopathies.

75
Q

Primary goal in preeclampsia and preeclampsia superimposed on chronic hypertension is to control the woman’s blood pressure and to prevent seizure activity and cerebral hemorrhage. Medical management includes:

A

Magnesium sulfate: To reduce seizure activity without documentation of long-term adverse effects to woman and fetus.
Antihypertensive medications are used to control blood pressure.
Delivery of the fetus and placenta is the only “cure” for preeclampsia.

76
Q

Nursing Actions for Preeclampsia:

A

Administer antihypertensive as per orders blood pressure >160/110mmHg.
Administer magnesium sulfate as per orders
Assess for CNS changes including headache, visual changes, deep tendon reflexes and clonus.
Auscultate lung sounds for clarity and monitor the respiratory rate.
Assess for signs and symptoms of pulmonary edema such as: SOB, chest tightness or discomfort, cough, oxygen saturation less than 95%, increased respiratory and heart rates.
Assess for epigastric pain or right upper quadrant pain indicating liver involvement.
Assess weight daily and assess for edema to assess for fluid retention.
check urine for proteinuria and specific gravity.
Evaluate laboratory values including:
Elevations in serum creatinine (72mg/dL)
Hematocrit levels(>35)
Low platelet count (100,000/mm3)
Elevated liver enzymes (AST?41units/L, ALT >30 units/L)
Perform antenatal fetal testing and fetal heart rate monitoring (NST & BPP)
Check intake of adequate calories and protein
Maintain I&O to evaluate kidney function.
Provide quiet environment to decrease CNS stimulation.
Maintain bed rest in the lateral recumbent position.
Provide information to the woman and her family.
Report deterioration in maternal or fetal status to provider.

77
Q

Eclampsia:

A

The occurrence of seizure activity in the presence of preeclampsia.

78
Q

HELLP syndrome:

A

(Hemolysis, Elevated Liver enzymes, and Low Platelets)
Is the acronym used to designate the variant changes in laboratory values that can occur as a complication of severe preeclampsia. hemolysis is a result of RBC destruction as the cells travel through constricted vessels.
Elevated liver enzymes result from decreased blood flow and damage to the liver.
Low platelets result from platelets aggregating at the site of damaged vascular endothelium causing platelet consumption and thrombocytopenia.

79
Q

Placenta Previa:

A

Occurs when the placenta attaches to the lower uterine segment of the uterus, near or over the internal cervical os instead of in the body or fundus of the uterus.

80
Q

Total placenta previa:

A

The placenta completely covers the internal cervical os.

81
Q

Partial placenta previa:

A

The placenta partially covers the internal cervical os.

82
Q

Marginal placenta previa:

A

The edge of the placenta is at the margin of the internal cervical os.

83
Q

Low-lying placenta:

A

The placenta is implanted in the lower uterine segment in close proximity to the internal cervical os.

84
Q

PPH can lead to what other diagnosis:

A

DIC

85
Q

How much blood loss is to much in a post partum patient with a vaginal birth?
