QUESTIONS AND ANSWERS
• Which basic type of pelvis includes the correct description and
percentage of occurrence in women? A) Platypelloid: flattened,
wide, shallow; 3%
B) Anthropoid: resembling the ape; narrower; 10%
C) Android: resembling the male; wider oval; 15%
D) Gynecoid: classic female; heart shaped; 75% Ans:
A) Platypelloid: flattened, wide, shallow; 3%
,• What position would be least effective when gravity is desired to
assist in fetal descent?
A) Lithotomy
B) Walking
C) Kneeling
D) Sittin g Ans:
A) Lithotomy
• The factors that affect the process of labor and birth,
known commonly as the five Ps, include all EXCEPT:
A) Passageway.
B) Powers.
C) Passenger.
D) Pressure.
D) Pressure.
Ans:
:: The 5 P's are:
1. Powers (contractions)
2. Passengers (fetus & placenta)
3. Passageway (birth canal)
4. Position (of the mother)
5. Psychological Response
,• While evaluating an external monitor tracing of a woman in active
labor, the nurse notes that the fetal heart rate (FHR) for five
sequential contractions begins to decelerate late in the contraction,
with the nadir of the decelerations occurring after the peak of the
contraction. The
LPN/LVN first priority is to: A)
Notify the care provider.
B) Assist with amnioinfusion
C) Change the woman's position
D) Insert a scalp electrode. Ans:
C) Change the woman's position
• A client is admitted to the labor and delivery unit with contractions
that are 3-5 minutes apart, lasting 60-70 seconds. She reports that she
is leaking fluid. A vaginal exam reveals that her cervix is 80 percent
effaced and 4 cm dilated and a -1 station. The LPN/LVN knows that
the client is in which phase and stage of labor?
A) Latent phase, First Stage
B) Active Phase of First Stage
C) Latent phase of Second Stage
D) Transition
Ans:
, B) Active Phase of First Stage
Second stage = full dilation until
birth
• To assess uterine contractions the LPN/LVN would
A) Asses duration from the beginning of the contraction to the peak of
the same contraction, frequency by measuring the time between
the beginning of one contraction to the beginning of the next
contraction.
B) Assess frequency as the time between the end of one contraction
and the beginning of the next contraction, duration as the length of
time from the beginning to the end of contractions, and palpate the
uterus for strength
C) Assess duration from beginning to end of each contraction. Assess
the strength of the contraction by the external fetal monitor
reading. Measure frequency by measuring the beginning of one
contraction to another.
D) Assess duration from beginning to end of each
contraction., frequency by measuring the time between the beginnings
