Nurs 221 Exam 2 Questions And Answers
2025 Update.
What do you use to assess uterine contractions? - Answer✔Tocometer
How many tocometers are there and where are they placed - Answer✔On the fundus for the
pressure of contractions and low on the belly for fetal heart rate
By what metric do you assess the frequency of contractions - Answer✔Number of contractions
in 10 min over a 30 minute window
Factors assessed in an assessment of uterine activity - Answer✔Frequency, duration, intensity,
relaxation
What is normal uterine activity - Answer✔Under 5 contractions in under 10 minutes, averaged
over 30 minutes
What is tachysystole - Answer✔over 5 contractions in 10 minutes, over 30 minutes
How can tachysystolic uterine contractions deprive the baby of 02 and why - Answer✔Too
frequent of contractions doesn't give the baby a break in between contractions and in turn
stops uterine blood flow too often
how do you palpate a uterine contraction - Answer✔1 hand's fingertips on top of fundus and
push with light pressure
How do you rate different uterine contraction strengths - Answer✔Mild = easily indented, like
the tip of a nose
Moderate = difficulty indenting like the chine
Strong = firm, can't indent easily like the forehead
what is a normal fetal heart rate - Answer✔110 - 160 bpm
How does the contraction's different parts affect blood flow - Answer✔Hump = no blood flow
Increment - reduced blood flow

Baseline - normal blood flow
What is an alternate way to measure the pressure baby and uterus are experiencing during a
contraction and when do you use it? - Answer✔Pressure catheter and during labor after
membranes rupture
Where do you place the pressure catheter? - Answer✔In the uterus next to the fetus
What is another way to measure fetal heart rate - Answer✔Fetal scalp electrode
When can you use a fetal scalp electrode - Answer✔If water is broken and you're dilated
What is a fetal scalp electrode contraindication - Answer✔contractible disease
When is the frequency of a contraction measured from - Answer✔the beginning of one
contraction to the beginning of the next one
When is the duration of a contraction measured from - Answer✔Beginning of one contraction
to the end of that same contraction
What is intensity of a contraction - Answer✔how strong a contraction is
what is the relaxation of a contraction - Answer✔period of no contraction
What are contractile indicators the baby is coming - Answer✔longer, stronger contractions and
less relaxation time
where do contractions originate - Answer✔top of cervical fundus
How do you get a fetal baseline heart rate - Answer✔assess for 2 minutes in a 10 minute
window
Why might a fetus have an absent heartrate - Answer✔baby is too young, it's not doing well, or
you need a better reading
How is minimal variability defined - Answer✔Detectable variation under 5 bpm
How is moderate variability defined - Answer✔Detectable variation between 6 and 25 bpm
what is marked variability - Answer✔FHR change of over 25 bpm
when do babies not have good variability - Answer✔younger than 32 weeks
What is FHR variability? - Answer✔How much the FHR varies
How does a variable deceleration present - Answer✔random, abrupt dips
what is variable deceleration caused by - Answer✔cord compression
what is an intervention for variable deceleration - Answer✔Maternal repositioning

How do early decelerations present - Answer✔Mirrors contraction, subtle, gradual, consistent
what is the cause of early decelerations - Answer✔Head compressions
intervention for early deceleration - Answer✔none, it means labor is eminent
How does a late deceleration present - Answer✔late in reference to contraction, it starts in the
middle of a contractile peak and ends after contraction end. gradual, and recurrent
cause of late deceleration - Answer✔placental insufficiency
intervention for late deceleration - Answer✔POISON
What does P stand for in POISON - Answer✔(P)osition mother to lateral (left side) position
First O in POISON - Answer✔(O)xytocin off
I in POISON - Answer✔IV lactated ringers
S in POISON - Answer✔Sterile vaginal exam
Second O in POISON - Answer✔O2 at 10 L nonbreather
N in POISON - Answer✔Notify physician
What can the intervention POISON also be used for - Answer✔variable decelerations
NCID EFM Category 1 classification (good) - Answer✔HR 110-160
Moderate Variability
No decelerations
Can have early decelerations, or accelerations
NCID EFM category 3 classification (bad) - Answer✔Absent baseline
recurrent late or variable decels
Bradycardia or sinusoidal pattern
what is leopolds maneuver - Answer✔palpating the gravida abdomen
step 1 in leopolds maneuver - Answer✔Palpate fundus for presentation (either head or butt)
Step 2 of Leopold's maneuver - Answer✔Palpate abdomen for Position (either hard spine or
soft belly)
Step 3 of Leopold's maneuver - Answer✔Palpate suprapubic area for a hard head to confirm
position
Step 4 of Leopold's maneuver - Answer✔Palpate abdomen down towards mom's feet (soft is
nose down, hard is chin up)
