WEEK 4 Flashcards
endocrine disorders hypertension disorders
pregestational diabetes mellitus (PDM)
chronic condition that will require management for a lifetime and is divided into two categories: type 1 diabetes mellitus (DM) and type 2 DM.
type 1 DM
autoimmune disorder that causes decreased or absent insulin production from the beta cells in the pancreas.
type 2 DM
may not have sufficient insulin production from the pancreas but do have insulin resistance at the cell wall, creating higher levels of circulating plasma glucose
vasodilation
Expansion of maternal blood vessels to accommodate the expected increase in maternal blood volume.
causes a decrease in baseline blood pressure
why does vasodilation occur
hormonal influences of estrogen, progesterone, relax begin to surge
why does the maternal blood volume increase
the renin-angiotensin-aldosterone system (RAAS) begins water and salt retention, expanding the maternal blood volume
what increases with pregnancy
SV
HR
CO
healthy BMI for pregnancy
less than 30
elevated BMI
can lead to hypertension
nonmodifiable risks for hypertension
chronic HTN to genetics
race
diagnosis before pregnancy
lower income (SDOH)
AMA (because body’s become less elastic)
primigravida
modifiable risk factors
BMI over 30
lack of excercise
lack of good diet
clinical presentation of hypertension
140/90 mmHg after 20 weeks of gestation
Clients presenting with no proteinuria and blood pressure readings of 140/90 mm Hg or higher on two occasions at least 4 hr apart will be diagnosed with gestational hypertension.
blood pressure reading
cuff should be an appropriate size
length 1.5 times the circumference
covers at least 80% of the arm
upright position for at least 10 min
abstained from caffeine at least 30 min prior to reading
Clients who have gestational hypertension have higher rates of
thrombocytopenia and liver dysfunction
thrombocytopenia
Platelet count less than 100,000/mm3.
HTN: weekly urine dipsticks to assess for what
proteinuria
liver enzymes
serum creatinine
CBC to assess platelets
manifestations of worsening HTN
visual changes or unresolved headache, lab testing should be repeated
what should have NST have
reactive: accelerations
why do we need to check liver functions of pregnant clients
watch clotting factor because it can lead to risk of hemorrhage
nonpharmacological interventions for HTN
adequate intake of fish oil, vitamin D, vitamin C, vitamin E, folic acid, and sodium reduction reduces the risk of a pregnancy-related hypertensive disorder
folic acid
prevents neural tube defects in fetal development
overloaded vascular system
HTN, lower sodium
pharma therapy for HTN
12-20 weeks take aspirin to help with blood flow
methyldopa
antihypertensive medication FINISH LATER
Labetalol
beta blocker (know that because of the -olol ending)
FINISH LATER
nifedipine
antihypertensive, calcium channel blocker FINISH LATER
Hydralazine
antihypertensive, vasodilator FINISH LATER
acute, severe HTN
hydralazine
greater than or equal to 160/110 mmHg
complications of HTN in pregnancy
preterm birth and maternal mortality
organ damage, proteinuria
chronic HTN need what
preconception counseling
could be on teratogenic medication
prevention
take BP and educate how to do it
refrain from smoking, drinking alcohol, eating high sugar/sodium foods
focus on walking, nutrition, gaining appropriate weight during their pregnancy
Clients who have a hypertensive disorder have a higher incidence
preterm birth
C section
placental abruption
preeclampsia
grief and loss with chronic hypertension or gestational hypertension
may affect the timing of birth, type of birth, postpartum recovery, and maternal–newborn bonding
preeclampsia
A hypertensive disorder diagnosed after 20 weeks of gestation or during the postpartum period involving organ injury. May express with or without severe features. Manifestations of preeclampsia include severe headache, visual changes, upper right abdominal pain, proteinuria, thrombocytopenia, unexpected kidney function, unexpected liver function, and pulmonary edema.
pathophysiology of preeclampsia
it is thought to involve unexpected placental implantation and inadequate blood flow to the placenta. thought to be shown that the placenta not being implanted the right way can impact this FINISH LATER
preeclampsia into two categories
preeclampsia without severe features and preeclampsia with severe features
placenta and preeclampsia
FINISH LATER
risk factors for preeclampsia
AMA
Use of assisted reproductive technology
Autoimmune disorders
Chronic hypertension
Chronic kidney disease
Diabetes
Fetal growth restriction
Gestational diabetes
Gestational trophoblastic disease
Multiple gestations
Nulliparity
Primigravida
BMI greater than 30
Obstructive sleep apnea
clinical presentation of preeclampsia without severe features
clinical presentation of preeclampsia with severe features
lab testing without severe features
greater than 140/90 mmHg
two occurrences at least 4 hours apart with ONLY proteinuria
lab testing with severe features
160/110 at two occurrences at least 4 hours apart with proteinuria and AT LEAST ONE symptom
Symptoms: persistent headache, pulmonary edema, right upper quadrant pain, or visual changes in conjunction
Additional: 24 hr urine sample; over 300 mg is considered positive for proteinuria; also CBC to test platelets (to test for thrombocytopenia)
preeclampsia fetal testing
increased BPP
testing a few times a week
how is a BPP done
ultrasound testing with even 2s
risk for what with preeclampsia
seizure due to high blood pressure
magnesium
2-4 g bolus to help with eclamptic seizure with a client who has preeclampsia with severe features
mom will be super relaxed, BUT still get a responses
magnesium
if you gave too much magnesium
leads to respiratory depression
decreased RR, no refluxes
administer calcium gluconate
how to check a persons reflex
deep tendon: hammer, hit with hands, stethoscope to elicit a response
does mag treat BP
NO, it is treating seizures. it will lower as a SYMPTOM but not the therapeutic use
antenatal steriods
betamethasone
difference with preeclampsia vs eclampsia
eclampsia causes seizures
had a seizure and preeclamptic, you are eclamptic
