Q

Describe how diabetes affects the pregnant woman and her fetus; identify nursing interventions

A

The primary concern for any woman with this disorder is controlling the balance between insulin and blood glucose levels to prevent hyperglycemia or hypoglycemia. Women with gestational diabetes are at an increased risk of complications during pregnancy and delivery.

Gestational: If glucose cant get into the cell

Note signs of hyperglycemia (confusion, increased thirst, frequent urination, changes in visual acuity) or hypoglycemia (dizziness; tremors; lethargy; excessive sweating, pale, cool, moist skin).

Q

Discuss hypertension in pregnancy, including risk factors, causes, symptoms, treatment(especially Magnesium sulfate) , and nursing care

A

Hypertension is identified as systolic pressure 140 mm Hg or greater or diastolic pressure 90 mm Hg or greater. Hypertensive disorders of pregnancy are the most common complication of pregnancy, affecting 10 percent of pregnant women, and are the second leading cause of maternal death and a significant contributor to neonatal morbidity and mortality.

● Preeclampsia is a multisystem hypertensive disease unique to pregnancy, with hypertension accompanied by proteinuria after the 20th week of gestation. Eclampsia is the onset of convulsions or seizures that cannot be attributed to other causes in a woman with preeclampsia.
●Chronic hypertension with superimposed preeclampsia includes the following scenarios:
Women with hypertension only in early gestation who develop proteinuria after 20 weeks of gestation.
Women with hypertension and proteinuria before 20 weeks who develop a sudden exacerbation of hypertension,
● Gestational hypertension: Systolic BP ≥ 140/90 for the first time after 20 weeks, without other signs and systemic finding of preeclampsia
● Chronic hypertension: Hypertension (BP ≥ 140/90) before conception. High blood pressure known to predate conception or detected before 20 weeks of gestation

Treatment:
● Magnesium sulfate, a central nervous system depressant, has been proven to help reduce seizure activity without documentation of long-term adverse effects to the woman and fetus.
● Antihypert
● Assess CNS changes, visual, reflexes

Risks for Woman
● Cerebral edema/hemorrhage/stroke
● Disseminated intravascular coagulation (DIC)
● Pulmonary edema
● Congestive heart failure
● Maternal sequelae resulting from organ damage include renal failure, HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets), thrombocytopenia and disseminated intravascular coagulation, pulmonary edema, and eclampsia (seizures), hepatic failure
● Abruptio placenta
● Women with a history of preeclampsia have a 1.5 to 2 times higher risk of developing heart disease later in life
● obesity
● Chronic HT, kidney disease, lupus, diabetes

Fetal Risk:
● Fetal/neonatal morbidity and mortality are consequences of intrauterine growth restriction (IUGR), prematurity, and placental abruption.
● Fetal intolerance to labor because of decrease placental perfusion
● Stillbirth

Q

Diabetes

A

Type1 : body isnt making insulin - body attacks destroys insulin producing cells.
Autoimmunity of beta cells of the pancreas resulting in absolute insulin deficiency and is managed with insulin. About 5%-10% of patients diagnosed with diabetes are type I

Type 2: body is producing enough insulin but not properly produced overweight can’t stop insulin production. fat deposits on cell can’t open. Characterized by insulin resistance and inadequate insulin production. This is the most prevalent form of diabetes and is linked to increased rates of obesity and sedentary lifestyle. It is managed primarily with diet and exercise; the addition of oral antihyperglycemic or insulin may be indicated if hyperglycemia continues.
- glucose can’t get into cells + trys to get rid of extra w. kidney
Challenge to manage because of
HPL
P
HgH
Corticotropin-releasing hormone

Shift energy source from ketone -> free fatty acid

Treatment:
Euglycemic control
minimize complication
prevent prematurity
-> keep the lowest possible glycosylated hemoglobin w/o going into hypoglycemia

Cardinal Signs
Polyuria
Polydipsia
Weight Loss
Polyphagia

Changes of insulin during pregancy
1st Tri: decreases
2nd-3rd: rises

Q

Preeclampsia

A

Preeclampsia is a kind of high blood pressure some women get after the 20th week of pregnancy or after giving birth. s high blood pressure and signs that some of her organs, like her kidneys and liver, may not be working normally. Blood pressure is the force of blood that pushes against the walls of your arteries. Arteries are blood vessels that carry blood away from your heart to other parts of the body. High blood pressure (also called hypertension) is when the force of blood against the walls of the blood vessels is too high. It can stress your heart and cause problems during pregnancy.

Imbalance of vasodilator hormones (prostacyclin) and vasoconstrictor hormones (thromboxane)

  • Leading cause of maternal death
  • 20wks 140/90 @ least 4 hrs apart + proteinuria >300mg or new systemic disease.

Q

Multiple Gestations

A

+1 fetus - either from the fertilization of one zygote that subsequently divides (MONOZYGOTIC) or fertilization of multiple ova.
● Monozygotic twins are from one zygote that divides in the first week of gestation. They are genetically identical and similar in appearance and always have the same gender.

● Dizygotic twins result from fertilization of two eggs and may be the same or differing genders. If the fetuses are of differing gender, they are dizygotic and therefore dichorionic.

● Either of these processes can be involved in the development of higher order multiples.

Q

Gestational Diabetes

A

hormone made by the placenta prevents the body from using insulin effectively. Glucose builds up in the blood instead of being absorbed by the cells. insulin less effective, a condition referred to as insulin resistance

Two main contributors to insulin resistance are:

● Increased maternal adiposity
● Insulin desensitizing hormones produced by the placenta

risk:
<25 yr
HT, PCOS
Increase in maternal adiposity
insulin desensitizing hormone
Family history/ age/ race/ obesity history of macrosomia

Diagnosis: glucose testing 24-28 wk

Complications:
Macrosomia
Shoulder dystocia
HT + preeclampsia
preterm birth + stillbirth
C-section

Risks for baby
excessive birth weight
preterm
breathing difficulties
hypoglycemia
obesity + type 2 later in life
stillbirth
hyperbilirubinemia
birth trauma
RDS

Prevention:
maintain healthy lifestyle, keep active, don’t gain more weight than recommended

Findings:
Glucose screening 24-28 wks of gestation

Management:
For most women with GDM, the condition is controlled with a well-balanced diet and exercise.
● Up to 40% of women with GDM may need to be managed with insulin.
● Oral hypoglycemic agents may be used, but there is not agreement on their recommended use during pregnancy.
● Cesarean birth is recommended for estimated fetal weight >4,500 g.
● Women with GDM need to be monitored for type 2 diabetes after the birth.

Nursing Actions:
Teach the woman to test glucose four times a day, one fasting and three postprandial checks/day (suggested glucose control is to maintain fasting glucose less than 95 mg/dL before meals, and between 120 to 135 mg/dL after meals)

Q

HELLP Syndrome

A

HELLP syndrome is a serious pregnancy complication that affects the blood and liver. HELLP stands for these blood and liver problems:

H–Hemolysis. This is the breakdown of red blood cells. Red blood cells carry oxygen from your lungs to the rest of your body.
EL–Elevated liver enzymes. High levels of these chemicals in your blood can be a sign of liver problems.
LP–Low platelet count. Platelets are little pieces of blood cells that help your blood clot. A low platelet count can lead to serious bleeding.

HELLP may develop in women who do not present with the cardinal signs of severe preeclampsia.

Risk for woman:
Abruptio placenta
Renal failure
liver hematoma / rupture
Death

Risk for fetus
Preterm birth
Death

Assessment:
general malaise, nausea, and right upper gastric pain.

Q

List the critical elements of performing a neonatal assessment

A

APGAR

Birth Weight

Measurements: Head, chest + length

Vitals: temp, pulse, respiration

Gestational assessment

Physical maturity: Ballard exam + Dubowitz
Points are given for each area of assessment. A low of -1 or -2 means that the baby is very immature. A score of 4 or 5 means that the baby is very mature (postmature). These are the areas looked at:

Skin textures. Is the skin sticky, smooth, or peeling?

Soft, downy hair on the baby’s body (lanugo). This hair is not found on immature babies. It shows up on a mature infant, but goes away for a postmature infant.

Plantar creases. These are creases on the soles of the feet. They can be absent or range up to covering the entire foot.

Breast. The provider looks at the thickness and size of breast tissue and the darker ring around each nipple (areola).

Eyes and ears. The provider checks to see if the eyes are fused or open. He or she also checks the amount of cartilage and stiffness of the ears.

Genitals, male. The provider checks for the testes and how the scrotum looks. It may be smooth or wrinkled.

Genitals, female. The provider checks the size of the clitoris and the labia and how they look.

Physical exam
General appearance. This looks at physical activity, muscle tone, posture, and level of consciousness.

Skin. This looks at skin color, texture, nails, and any rashes.

Head and neck. This looks at the shape of head, the soft spots (fontanelles) on the baby’s skull, and the bones across the upper chest (clavicles).

Face. This looks at the eyes, ears, nose, and cheeks.

Mouth. This looks at the roof of the mouth (palate), tongue, and throat.

Lungs. This looks at the sounds the baby makes when he or she breathes. This also looks at the breathing pattern.

Heart sounds and pulses in the groin (femoral)

Abdomen. This looks for any masses or hernias.

Genitals and anus. This checks that the baby has open passages for urine and stool.

Arms and legs. This checks the baby’s movement and development.

Q

Describe reflexes present in a neonate

A

Moro: startle reflex - lifts arms and legs curl them back toward body and throw head back
abnormal Moro reflex which only involves one side of the body. Other babies may have no Moro reflex at all. Some causes of an abnormal or absent Moro reflex may include infections, muscle weakness, injuries from childbirth, peripheral nerve damage and spastic cerebral palsy. disappear around 6 mo.

Rooting: when you touch the cheek of an infant baby turns head
The rooting reflex in babies usually lasts for about four months. After that, rooting becomes a voluntary response rather than a reflex

Sucking: 32 weeks inside the mother’s womb. roof of the mouth is stimulated or when you place the mother’s breast or a bottle in his/her mouth, the baby will place the lips over the nipple and squeeze it between the tongue and roof of the mouth. Next, the baby will move his/her tongue to the nipple to suck and milk the breast. The sucking reflex usually lasts until the baby is four months old.

Tonic Neck: fencing reflex, the tonic neck reflex happens when the baby’s head turns to one side. This is triggered when you stroke or tap the side of the baby’s spine while the baby lies on his/her stomach.
Tonic neck reflex may last until the baby is around five to six months old.

Grasp: stroking or touching the palm of a baby may cause the baby to automatically close his/her hands. The grasp reflex may last until the baby is about five to six months old.

Babinski: firmly stoke the sole of the baby’s foot. The baby’s big toe moves upward or toward the top of the foot and the other toe fans out. until the child is about two years old, but for some, it goes away after a year.

Stepping: walking or dancing reflex. Stepping reflex happens when you hold the baby upright with his/her feet touching a flat surface. You will notice that the baby will move his/her legs as if he/she is walking or trying to take steps although the baby is still too young to actually walk. lasts for about two months.

96
Q

Hyperbilirubinemia

A

The majority of bilirubin is produced from the breakdown of Hb into
unconjugated bilirubin (and other substances). Unconjugated bilirubin binds to
albumin in the blood for transport to the liver, where it is taken up by
hepatocytes and conjugated with glucuronic acid by the enzyme uridine
diphosphogluconurate glucuronosyltransferase (UGT) to make it water-­‐soluble.
The conjugated bilirubin is excreted in bile into the duodenum. In adults,
conjugated bilirubin is reduced by gut bacteria to urobilin and excreted.
Neonates, however, have sterile digesive tracts. They do have the enzyme β-­‐
glucuronidase, which deconjugates the conjugated bilirubin, which is then
reabsorbed by the intestines and recycled into the circulation. This is called
enterohepatic circulation of bilirubin

PHYSIOLOGIC JAUNDICE
Hyperbilirubinemia commonly occurs ager first 24 hours (typically 2-­‐5 days)
Increased bilirubin related to rela:ve polycythemia and short life span of fetal red bloods (80 days)
Decreased uptake of bilirubin by the liver
Decreased enzyme ac:vity and ability to conjugate bilirubin –low levels of enzyme to conjugate
Decreased ability to excrete bilirubin
Increased enterohepatic circulation-­‐increased B-­‐glucoronidase (a deconjuga:ng enzyme)
Breast feeding

ATHOLOGICAL JAUNDICE
Jaundice that occurs within the first 24 hours of life.
Total serum bilirubin levels above 12 mg/dL in a term neonate or 15 mg/dl in a preterm baby or >95th % on nomogram
Total serum bilirubin levels that increase by more than 5 mg/dL per day (or 0.2 mg/dL per hour)
Conjugated bili >2 mg/dl
Jaundice lasting >1 wk term/ > 2k premature

97
Q

Bilirubin Encephalopathy

A

Q

Respiratory Distress Syndrome

A

Hyaline membrane disease
primary absence of pulmonary surfactant
indicates failure to synthesize surfactant

Assessment: grunting, flaring, retracting, tachy, skin grays, hypoxemia, acidosis

Management
O2, Pulse ox, surfactant replacement, CPAP, mechanical ventilation ECMO

102
Q

Transient Tachypnea of Newborn

A

Failure to clear fluid of out lunfs

Exhibits distress shortly after birth

SS:
Expiratory grunting and nasal flaring
subcostal retractions
slight cyanosis

Maintain adequate respir, nutritional, hydration status and education

103
Q

Meconium Aspiration Syndrom

A

Mechanical obstruction of airways
chemical pneumonitis
vasocon of pulmonary vessels
inactivsation of natural surfactant
assess for complications

maintain respir + nutrition + hydration
