Exam 2 Flashcards
Recommended weight gain for a singleton
Underweight: 28-40
Normal: 25-35
Overweight: 15-25
Obese: 11-20
Emotional impact of a singleton
Accepting pregnancy: ambivalence and mood swings and normal
Preparing for birth and mother role
Establishing attachment to fetus
Prenatal chromosomal abnormality tests
XX female XY male Normal largo type: 46 chromosomes Extra or missing chromosomes can occur Advanced maternal age increases risk of abnormalities
Psychological effects of high risk pregnancy
Disruption of family roles
Financial strain
Frustration with activity restriction
Thromboembolic disorders
DVT Other risk factors of DVT: Advanced maternal age Multigravida Use of OCPs before Smoking Employment with prolonged standing S and S: Unilateral leg pain Swelling and tenderness Decrease risk: Use SCDs or compressive stockings Leg and ankle exercises Avoid positioning with sharply flexed knees Hydration
Signs and symptoms of pulmonary embolism
Sob
Tachypnea
Tachycardia
Gestational HTN
Onset after 20 weeks
No proteinuria
Preeclampsia
High bp which causes damage to another organ system (usually kidneys)
Causes decreased placental perfusion
Increased risk later in life for cv disease and kidney disease
Scotoma and HTN
Visual disturbances and HTN in pregnancy
Major red flag
Eclampsia
Onset of seizures or coma
During seizure: place woman on side if possible
Time the seizure
After: first priority is abc, then fetal assessment
Magnesium sulfate
Drug of choice to prevent seizure activity
Therapeutic serum level: 4-7 mEq/L
Calcium Gluconate is antidote
Signs of toxicity:
Respiratory depression (rr less than 12)
Slurred speech
Oliguria
Diabetes and pregnancy
Insulin resistance occurs during 2nd and 3rd trimesters to meet nutritional demands of fetus
If body is unable to produce enough insulin to counteract: gestational diabetes mellitus can occur
Diabetes screening
Risk factors
Infant
Screening: 24-28 weeks Fasting glucose should be under 95 Risk factors Previous macrosomic infant Multifetal pregnancy Ethnicity Can cause macrosomia in the infant Mom should be periodically screened for type 2 DM after pregnancy
Pregnant women with preexisting diabetes
Poor glycemic control before and during early pregnancy can cause congenital anomalies
Hemorrhagic disorders of pregnancy
Vaginal bleeding is a warning sign that should be further evaluated
Especially if in first trimester
Placenta previa
Bright red bleeding with no pain
Placenta implanted in lower uterine segment, partially over cervical os
Vaginal exams are contraindicated
Placental abruption warning signs
Abdominal pain
Dark red bleeding
Hyperemesis gravidum
Excessive vomiting and loss of 5% of prepregnancy weight
Intractable nausea and vomiting during first trimester
Causes disturbance in nutrition and fluid and electrolyte balance
Meds for nausea
Monitor
Encourage intake of small portions
Monitor urine for ketones
False vs true labor
True: regular contractions, get closer and stronger over time, don’t change with position or walking
False: irregular contractions, may stop with walking or position change, cervix not effaced or dilated
Signs preceding true labor
Bloody show
Surge of energy
Lightening
Passing of mucus plug
Contractions
Purpose
Relaxation phase
Palpation
Purpose
First stage: cervical dilation and
effacement
Second: birth
Third: expulsion of placenta, minimize bleeding
Relaxation phase: important bc contractions can affect fetal oxygenation
Duration longer than 90 sec or interval more frequent than 60 sec can cause fetal compromise
Mom’s BP: will increase at peak of contraction
Mom’s CO: increase during labor
Palpation: evaluate intensity of contractions by pressing fingertips into fundus
