VERSION A
With abruptio placentae, fetal death is common with
separation of
a. at least 15%
b. at least 25%
c. at least 50% - ....ANSWER...C
(premature detachment of placenta from the uterus). It is
associated with maternal hypertension and cocaine use.
Intrauterine growth retardation occurs with partial
detachment because the fetus lacks adequate nourishment.
If total detachment occurs, hemorrhage may occur, with
half of those affected exhibiting coagulopathy.
Complications can include fetal distress, fetal death,
1
,hypotension, DIC, and maternal death. Partial placental
abruption is treated with bedrest and monitoring;
complete separation requires immediate vaginal delivery
or cesarean.
When a transabdominal ultrasound is used to localize the
placenta for an amniocentesis in gestation week 32, the
woman should generally be advised to
a. empty the bladder before the procedure
b. drink 1.5 to 2 quarts of water 2 hours prior to the
procedure
c. drink 3 to 4 glasses of water immediately prior to the
procedure - ....ANSWER...A
If the amniocentesis is done early in pregnancy, then it is
often done with a full bladder. A full bladder helps the
examiner to assess other structures, such as the cervix and
vagina, and is important if the patient is being assessed for
vaginal bleeding or placenta previa.
The first step in quality improvement measures on the
nursing unit is to
a. brainstorm methods to enhance the unit's level of care
b. formulate a plan to implement quality-improvement
2
,measures
c. identify the areas in need of improvement on the unit -
....ANSWER...C
Begin with identifying those things in need of
improvement. Without an assessment of needs, quality
improvement measures may be misguided. This may begin
with failure mode and effects analysis (FMEA), gap
analysis, internal research (data analysis, surveys,
interviews, observation), root-cause analysis, tracer
methodology, or other methods of brainstorming. Once
problems or areas for potential improvement are
identified, then some method of brainstorming is used to
generate solutions from which one or more is selected.
Plans are formulated, tested, and implemented. Following
implementation, the changes are monitored and modified
as needed.
During labor, if the presenting part has reached the level
of the ischial spines, the station is
a. 0
b. -1
c. +1 - ....ANSWER...A
Station refers to the position of the presenting part in
relation to the ischial spines, which are usually the
3
, narrowest area through which the fetus must pass during
delivery. If the presenting part is higher than the level of
the ischial spines, the station is designated with negative
numbers (-1 to -5) with each number representing a
centimeter. If the presenting part is below the level of the
ischial spines, the station is designated with positive
numbers (+1 to +5).
A maternal serum screen that shows increased levels of
human chorionic gonadotropin (hCG) and inhibin A and
decreased levels of unconjugated estriol (uE3) and alpha-
fetoprotein (AFP) is an indication of
a. Down syndrome
b. spina bifida
c. Turner syndrome - ....ANSWER...A
The maternal screening test is done to screen for
chromosomal abnormalities, and screens for three or four
substances: AFP, hCG, uE3, and sometimes inhibin A. A
positive finding should be followed by further testing, such
