Q&A (V1) Updated Questions with 100 Correct
Answers
• A patient 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 thepatient is in which
phase and stage of labor?
• Latent phase, First Stage
• Active Phase of First Stage
• Latent phase of Second Stage
• Transition
Ans:
B) Active Phase of First Stage Second
stage = full dilation until birth
• To assess uterine contractions the LPN/LVN would
• Asses duration from the beginning of the contraction to the peak ofthe
same contraction, frequency by measuring the time between the beginning
of one contraction to the beginning of the next contraction.
• Assess frequency as the time between the end of one contraction andthe
beginning of the next contraction, duration as the length of time from the
beginning to the end of contractions, and palpate the uterus forstrength
• Assess duration from beginning to end of each contraction. Assessthe
strength of the contraction by the external fetal monitor reading. Measure
frequency by measuring the beginning of one contraction toanother.
,• Assess duration from beginning to end of each contraction.,
frequency by measuring the time between the beginnings of
contractions, and palpate the fundus of the uterus for strength.Ans:
D) Assess duration from beginning to end of each contraction., frequency by
measuring the time between the beginnings of contractions, and palpatethe
fundus of the uterus for strength.
• Which basic type of pelvis includes the correct description and percentageof
occurrence in women?
• Platypelloid: flattened, wide, shallow; 3%
• Anthropoid: resembling the ape; narrower; 10%
• Android: resembling the male; wider oval; 15%
• Gynecoid: classic female; heart shaped; 75%Ans:
A) Platypelloid: flattened, wide, shallow; 3%
• What position would be least effective when gravity is desired toassist
in fetal descent?
• Lithotomy
• Walking
• Kneeling
• SittingAns:
A) Lithotomy
• The factors that affect the process of labor and birth, known
commonly as the five Ps, include all EXCEPT:
• Passageway.
• Powers.
• Passenger.
• Pressure.
, D) Pressure.
Ans:
:: The 5 P's are:
• Powers (contractions)
• Passengers (fetus & placenta)
• Passageway (birth canal)
• Position (of the mother)
• 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 nadirof
the decelerations occurring after the peak of the contraction. The
LPN/LVN first priority is to:
• Notify the care provider.
• Assist with amnioinfusion
• Change the woman's position
• Insert a scalp electrode.Ans:
C) Change the woman's position
• During labor a fetus with an average heart rate of 175 beats/min overa 15-
minute period would be considered to have:
• A normal baseline heart rate.
• Bradycardia.
• Hypoxia.
• Tachycardia.
Ans:
D) Tachycardia.
