Q

SEPSIS NEONATORUM

A
  • Infection that occurs during or after birth may result in sepsis neonatorum, a systemic infection from bacteria in the bloodstream.
  • COMMON CAUSES - agents of neonatal sepsis include bacteria such as GBS, Escherichia coli, coagulase-negative Staphylococcus, Staphylococcus aureus, Haemophilus influenzae, and fungi such as Candida albicans
  • Infection. In the newborn, early signs of infection are not as specific or obvious as those in the older infant or child. Instead, they tend to be subtle and could indicate other conditions.

Deontologic Model.
- The deontologic model determines what is right by applying ethical principles and moral rules. - does not vary the solution according to individual situations. *******example is the rule, “Life must be maintained at all costs and in all circumstances.” Strictly used, the deontologic model would not consider the quality of life or weigh the use of scarce resources against the likelihood that the life maintained would be near-normal.
34
Utilitarian Model
- The utilitarian model approaches ethical dilemmas by analyzing the benefits and burdens of any course of action to find one that will result in the greatest amount of good. - Appropriate actions may vary with the situation when using the utilitarian model. - concerned more with the consequences of actions than the actions themselves. - ****“The end justifies the means.” If the outcome is positive, the method of arriving at that outcome is less important.
35
Human Rights Model.
- The belief that each person has human rights is the basis for the human rights model to making ethical decisions. - The nurse may find personal difficulty in the right of a person to refuse care that the nurse and possibly other care providers believe is best. - A nurse’s goal is usually to save lives but what if the person’s life is intolerable or care is refused?

What happens with insulin release in early pregnancy?
Insulin release in response to serum glucose levels accelerate which can result in hypoglycemia
104
What occurs during the second half of pregnancy that creates maternal resistance to insulin?
- placental hormones rise, particularly estrogen, progesterone, and human placental lactogen (hPL) which create resistance to insulin in maternal cells
105
Why does insulin resistance occur during the 2nd half of pregnancy?
- to allow an abundant supply of glucose to be available for the fetus
106
Effects of Diabetes in the Postpartum Period
- The need for additional insulin falls during the postpartum period. - Breastfeeding is encouraged to help lower the amount of insulin needed in women with types 1 and 2 diabetes mellitus. - The woman with gestational diabetes mellitus (GDM) usually needs no insulin after birth but the greater risk for later development of type 2 diabetes should be emphasized with teaching before discharge.
107
Maternal Effects of Pre-Existing Diabetes TYPE 1

109
In which trimester is it most important to manage blood glucose levels for diabetic mothers?
First Trimester *Maternal hyperglycemia during organ formation in first trimester can cause congenital anomalies
110
Adverse effects of Diabetes on Fetus and neonate
- Hypoglycemia - Polycythemia - Hyperbilirubinemia - Hypocalcemia - Respiratory distress syndrome - Excess insulin retards cortisol production which is necessary for th esynthesis of surfactant
111
Insulin is considered a ______ hormone, thus Fetal hyperglycemia stimulating production of insulin to metabolize carbohydrates; excess nutrients transported to fetus can also cause increased growth
growth hormone
112
Vascular impairment in a Diabetic mother can cause what in the fetus?
- Polycythemia - IUGR - Perinatal death
113
What causes Hypoglycemia in a neonate?
Neonatal hyperinsulinemia after birth when maternal glucose is no longer available (but insulin production remains high)
114
What dictates the inappropriate growth of an infant of a diabetic mother?
- Vascular impairment =IUGR | - NO vascular impairment= - the infant is likely to be large if maternal glucose levels remain too high
115
How can Fetal hyperinsulinemia cause Respiratory distress?
- hyperinsulinemia retards cortisol production, which is necessary for the synthesis of surfactant
116
Glucose Challenge Test.
- A GCT is administered between 24 and 28 weeks of gestation, often to both low- and high-risk antepartum patients. - . Fasting is not necessary for a GCT, and the woman is not required to follow any pretest dietary instructions. - STEPS: The woman should ingest 50 g of oral glucose solution. A blood sample is taken 1 hour later. If the blood glucose concentration is 140 mg/dL or greater, a 3-hour oral glucose tolerance test is recommended.
117
Oral Glucose Challenge Test. *is more likely to be used for diagnosis following abnormally high GCT results
OGTT is the gold standard for diagnosing diabetes, but it is a more complex test. - The woman must fast from midnight on the day of the test. After a fasting plasma glucose level is determined, the woman should ingest 100 g of oral glucose solution. Plasma glucose levels are then determined at 1, 2, and 3 hours.
118
Intrapartum management of women with heart disease
- Careful management of IV fluid administration is essential to prevent fluid overload. - The woman should be positioned on her side, with her head and shoulders elevated. - Oxygen is administered to increase blood oxygen saturation and is monitored with pulse oximetry. - Bonnie says Epidural is recommended - Discomfort should be reduced to a minimum - The environment is kept as quiet and calming as possible to decrease anxiety, which can cause tachycardia - Maternal signs of cardiac decompensation (tachycardia, rapid respirations, moist rales, and exhaustion) should be reported immediately to the physician. - Vaginal birth is recommended for a woman with heart disease unless there are specific indications for a cesarean birth. - Vacuum extraction or outlet forceps are often used to minimize maternal pushing and use of the Valsalva maneuver and to limit prolonged labor, which can add to the hemodynamic stress for the woman with cardiac disease. - The fourth stage of labor is associated with special risks. After delivery of the placenta, about 500 mL of blood is returned to the intravascular volume. To minimize the risks of overloading the heart, abrupt positional changes should be avoided. - the uterus should not be massaged to expedite separation of the placenta. - Careful assessment for signs of circulatory overload, such as a bounding pulse, distended neck and peripheral veins, and moist rales in the lungs, is performed throughout labor and the postpartum period.
119
Signs of Intrauterine Drug Exposure* Relating to Feeding
- Exaggerated rooting reflex - Excessive sucking - Uncoordinated sucking and swallowing - Frequent regurgitation or vomiting - Diarrhea - Weight loss
120
Signs of Intrauterine Drug Exposure* - Other Signs
- Hypertension - Fever - Diaphoresis - Excoriation - Mottling
121
Optimal identification of the GBS carrier status is obtained by vaginal and rectal culture between___-___ weeks of gestation.
35-37 weeks of gestation (BONNIE SAYS 34 - 36)
122
Nursing management of GBS positive women
- Penicillin is the first-line agent for antibiotic treatment of the infected woman during birth. - Cephazolin is the alternative for the patient with non–life-threatening penicillin allergy. - Clindamycin is used for the woman at high risk for anaphylaxis.
123
What is Neonatal Abstinence Syndrome (NAS),
a disorder in which infants exposed to maternal drugs before birth demonstrate signs of drug withdrawal.
124
Signs of drug exposure usually begin during the first ___-__ hours after birth but may not occur for up to 4 weeks depending on the specific drug, the dose, and the times of the mother's last use.
24 to 72
125
(Didn't know how to put important stuff into a question) Infants with NAS may be irritable and have hyperactive muscle tone and a high-pitched cry. Although they have tremors, the blood glucose level is normal. Infants appear hungry and suck vigorously on their fists but have poor coordination of suck and swallow. Frequent regurgitation, vomiting, and diarrhea are common. Infants are restless, and their excessive activity coupled with poor feeding ability results in . Seizures may occur.
- Irritability - Jitteriness, tremors, seizures - Muscular rigidity, increased muscle tone - Restless, excessive activity - Exaggerated Moro reflex - Prolonged high-pitched cry - Difficult to console - Poor sleeping patterns - Yawning - failure to gain weight
126
Nursing management of SGA infants
- assess for hypoglycemia, especially in asymmetric, growth-restricted infants. The brain of the infant is normal and needs large amounts of glucose, but the liver is small and has inadequate stores of glycogen. - Caloric needs are greater than for a normal infant, making early and more frequent feedings important. - Temperature regulation and respiratory support are additional nursing concerns. - Observation for jaundice is important in infants with polycythemia because a large amount of bilirubin may be released when the red blood cells break down.
127
Uterine involution
``` Immediately after birth: U/2 6-12 hours after birth: @U Subsequent involution :1 fb (cm) per day Day 7: ½ way between umbilicus and symphysis pubis Non palpable by : 14th day (into pelvis) Pre pregnant size by 5-6 weeks. ```
128
Nursing Focus of the immediate post partum patient
- Provide adequate care for safety and comfort - Prepare for anticipatory guidance for expected change - Provide patient education for care of self and infant - Identify physical and emotional changes for normalcy and potential deviations
129
If the growth restriction is asymmetric, the head circumference and length are _________, but the abdominal circumference and weight are _____.
Normal Low
130
The nurse knows how to manage the various interventions for a postpartum patient
- get patient to walk - assist pt w/ breastfeeding - good pericare - emptying bladder frequently
131
Characteristics of late preterm infants
- look like full-term infants, yet physiologically immature. - at risk for respiratory disorders, problems with temp maintenance, hypoglycemia, hyperbilirubinemia, feeding difficulties, acidosis, and infection. - have immature suck and swallow reflexes, have shorter awake periods, and may fall asleep during feedings
132
Hemoglobin and Hematocrit values
Hgb - 10 (infusions start at 8.5) | Hematocrit - 35-46
133
Mothers with diabetes whose blood sugar is not in control in the 1st trimester are are higher risk for
- pre-clampsia - polyhydraminos - risk of prom - risk of macrosomia
134
What vaccine should pregnant women receive with EACH pregnancy?
Tetanus, Diphtheria, Pertussis. Recommended during every pregnancy. Prevents whooping cough which is deadly to baby. Vaccine is given to everybody around baby.
