Module 2 Labor, Birth, and Post Partum Flashcards
Any medication that suppresses contractions makes your blood pressure go up or down?
Go down
What are the 5 factors that affect the labor process?
Passenger, Powers, Passageway, Position, and Psychological Status
Who is the passenger?
The fetus and the placenta
Define power.
Uterine contractions cause effacement during the first stage of labor and dilation of the cervix that occurs once labor has started and the fetus is descending.
What is the passageway?
The birth canal
Define position. (5 factors that affect the labor process)
The client should change positions during labor to increase comfort, relieve fatigue, and promote circulation.
Involuntary urge to _____ and voluntary ______ ______ in the second stage of labor helps in the evacuation of the fetus.
Push, Bear Down
What is effacement?
The shortening and thinning of the cervix.
What is the introitus?
The vaginal opening
The size of the fetal ____, fetal ______, fetal ___, fetal ________, and fetal _______ affect the ability of the fetus to navigate the birth canal.
Head, Presentation, Lie, Attitude, and Position
When the membranes rupture, what do you think is the priority nursing action?
Assess the fetal heart rate.
Any alteration to the five P’s will _____ labor.
Slow
Pneumonic for TRUE Labor:
T: Timing of contractions- can be irregular then become regular increasing in frequency.
R: Radiating contraction pain that begins in the lower back and radiates to the abdomen.
U: Unable to relieve w/ activity. Walking can increase contraction intensity.
E: Effacement: True labor leads to dilation of the cervix and effacement (the shortening and thinning of the cervix.

F: Fails to cause changes- No significant change in dilation or effacement.
A: Activity diminishes contractions
K: Keep feeling contractions above the belly button. (or felt in lower back, but does NOT radiate)
E: Erratic timing of contractions- The contractions are painless, irregular, and intermittent.

E: Erratic timing of contractions- The contractions are painless, irregular, and intermittent.
Name the characteristics of TRUE Labor.
True labor leads to cervical dilation and effacement,
Contractions can begin irregularly, but become regular in frequency, Contractions are stronger, last longer, and are more frequent, Contractions are felt in the lower back, then radiating to the abdomen, Walking can INCREASE contraction intensity, Contractions continue despite efforts to provide comfort, The cervix has a progressive change in dilation and effacement and moves to an anterior position, BLOODY SHOW, Fetus; the presenting part engages in pelvis.
Name the characteristics of FALSE Labor.
Contractions are painless, irregular frequency, and intermittent, Contractions decrease in frequency, duration, and intensity with walking or position changes, The contractions are felt in the lower back OR abdomen ABOVE the umbilicus. (Does NOT radiate), The contractions often stop with sleep or comfort measures (oral hydration, EMPTYING THE BLADDER), There is no significant change in cervix dilation or effacement, Often remains in the posterior position, NO SIGNIFIGANT BLOODY SHOW, Fetus: the presenting part is not engaged in the pelvis.
In vaginal exams, what are we assessing?
Cervical dilation, Descent of the fetus through the birth canal, Fetal position, Presenting part, and lie, Membranes that are intact or ruptured
What assessment data should be gathered upon admission?
Maternal and fetal well-being during labor, the progress of labor, psychosocial and cultural factors that affect labor, vitals, etc.
What are Leopold maneuvers?
Leopold maneuvers consist of feeling the uterus through the abdominal wall to determine the number of fetuses, presenting part, fetal lie, and fetal attitude, the degree of the presenting part into the pelvis, location of the fetus’s back to assess for fetal heart tones.
How should a client be positioned when performing Leopold maneuvers?
Supine position with a pillow under the head, and have both knees slightly flexed.
What should you ask the client to do before beginning Leopold maneuvers?
Empty their bladder
What should you do to prevent supine hypotensive syndrome when performing Leopold maneuvers?
Place a small, rolled towel under the client’s right or left hip to displace the uterus off the major blood vessels.
For VERTEX presentation, where should fetal heart tones be assessed?
Below the clients belly button (umbilicus) in either the right- or left- lower quadrant of the abdomen.
For BREECH presentation, where should fetal heart tones be assessed?
Above the clients belly button in either the right- or left- upper quadrant of the abdomen.
Describe lightening regarding physiological changes preceding labor.
The process of the fetus settling or lowering into the true pelvis about 14 days before labor; the feeling that the fetus has “dropped”; it makes for easier breathing, but it does put more pressure on the bladder causing urinary frequency and it is more pronounced in clients who are primigravida.
Describe uterine contractions regarding physiological changes preceding labor.
They begin with irregular uterine contractions (Braxton Hicks) that eventually get stronger and more regular.
Describe vaginal discharge or bloody show regarding physiological changes preceding labor.
Brownish or blood-tinged mucus plug resulting from the onset of cervical dilation and effacement. Expulsion (getting something out of the body) of the cervical mucus plug may occur.
Describe energy burst regarding physiological changes preceding labor.
Sometimes called “nesting” response. (the urge to clean and organize)
Describe the GI changes regarding physiological changes preceding labor.
They are less common but inclue, nausea, vomiting, or indigestion.
For a vaginal exam preceding labor, what do we wear especially if the water is broken?
Sterile Gloves
What lab test would confirm the premature rupture of membranes?
Positive nitrazine paper test
When is the assessment of amniotic fluid done?
Once the membranes rupture
What should the amniotic fluid look like?
Watery, clear, and have a slight yellow tinge.
Odor should NOT be foul.
What should be the volume of amniotic fluid?
700 to 1,000 mL
Describe cervical ripening.
The cervix becomes soft (opens) and partially effaced, and can begin to dilate.
Labor usually occurs within __ hours of the rupture of membranes.
24
Prolonged rupture of membranes GREATER than 24 hours before delivery of fetus can lead to a(n) ________.
Infection
How do we assess uterine labor contraction characteristics?
palpation (placing a hand over the fundus), or by external or internal fetal monitoring.
Established from the beginning of one contraction to the end of beginning of the next.
Frequency of contractions
The time between the beginning of a contraction to the end of that same contraction.
Duration
The strength of the contraction at its peak, described as mild, moderate, or strong.
Intensity
Describe how a MILD contraction would feel upon palpation.
Slightly tense, like pressing finger tip of nose
Describe how a MODERATE contraction would feel upon palpation.
Firm, like pressing finger to chin.
Describe how a STRONG contraction would feel upon palpation.
Rigid, like pressing finger to forehead.
Tone of the uterine muscle between contractions.
Resting tone of uterine contractions.
If the baby CAN NOT fit through the pelvis, what happens?
A c-section will be performed.
What is the circumference of the pelvic inlet? (to know if baby can fit through)
385mm
The circumference of the babies head should be ____ to ____ to be able to fit through the mothers 385 mm pelvic inlet.
320-370 mm
If a client tells you they have experienced a gush or leakage of clear fluid from the vagina, what has happened?
Rupture of membranes
Abrupt FHR variable or prolonged deceleration and a visible or palpable cord at the vaginal opening indicate what complication of rupture of membranes?
Prolapsed umbilical cord
What cephalic (head) presentation is IDEAL for birth?
Vertex
Is there anything you can do to fix a cephalic presentation that is NOT ideal?
No
What are the four different cephalic presentations?
Vertex, military, brow, and face
Describe breech presentation.
The fetus’s bottom is first and NOT the head. It has a higher risk for complications, and most HCP want a c-section.
