nursing 135 midterm study guide
Ans✓✓✓ *classification of abruptio placenta:
class 0: asymptomatic; diagnosed after birth.
-class 1: mild; most common, occurring 50% of cases
-Class 2: moderate; both mother and fetus show signs of destress.
(occur 30
5 of cases)
-class 3: severe; maternal shock and fetal death likely; (occur 24%
cases)
Abruptio placentae Ans✓✓✓ description:
Premature separation of a normally implanted placenta from the
uterine wall; may be a catastrophic event depending on the severity of
the resulting hemorrhage, which may be vaginal or may be unseen
because it collects in the uterus or abdomen.
manifest:
rigid and painful abdomen
can occur any time during pregnancy
bleeding can be apparent or occult
uterine tension without rest
interventions/ therapies:
, -Monitor uterine resting tone, which is frequently increased with
abruptio placentae (uterine resting tone is the pressure within the
uterus btw contractions. in a term woman is less than or equal to 20
mm Hg , and is assessed by palpating the uterus during and btw
contractions).
-Monitor abdominal girth measurements to determine internal blood
collection. (Uterine size increases as bleeding occurs at the separation
site. use a measuring tape at the umbilicus area to measure q 15
minutes)
-Monitor vital signs, hemoglobin and hematocrit, and urine output.
(amjor cause is HTN)
alterations in perfusion Ans✓✓✓ alterations in perfusion due to
(whatever reason) can lead to acute ventilation failure, which leads to
acute respiratory acidosis; which can be due to drug induces respiratory
depression, inadequate ventilation due to neuromuscular disease or
paralysis ,and airway obstruction.
alterations due to clotting disorders:
clotting disorders can result in excessive bleeding (in disseminated
intravascular coagulation) or excessive clotting (deep vein thrombosis).
-clotting can occur only if body have enough platelets and clotting
factors.
