Toni - Week 3 - Exam 2 Flashcards
what are the 6 premonitory signs that indicate labor is near?
lightening, bloody show, cervical ripening, stronger braxton hicks, energy burst, and spontaneous rupture of membranes (SROM)
T/F: premonitory signs mean that labor is near or that it will occur in a set time frame.
FALSE. doesn’t necessarily mean labor
how is lightening defined?
occurs mostly with first time mothers; “baby has dropped” - mothers notice they can take a deep breath again
how is bloody show defined?
little capillaries break and vaginal mucus mixes with blood
how is cervical ripening described?
cervix feels as hard as your forehead/nose then softens to your lips
Stronger Braxton Hicks contractions can ___ the mother
confuse
what occurs during the sudden energy burst?
very common; women begin nesting, cleaning, folding baby clothes
how is the SROM described?
amniotic fluid bag ruptures, water has broken
what is the concern when bag membranes have ruptured?
the sterile environment has been open; bacteria migration is open;
what do we recommend when bag membranes have ruptured?
we recommend the mother comes into the hospital; she can put on a pad and we can test for amniotic fluids; we can do a sterile speculum we should start the clock b/c labor can start within 18 hrs
what is the definition of true labor? how many stages?
when contractions increasingly regular, longer, stronger, and more frequent - at least 40 - 45 second contractions; 4 stages
when is the first stage of labor?
onset of labor to complete dilation; contractions are closer together; progressive effacement and dilation; 10 cm or no cervix left
when is the second stage of labor?
complete dilation to birth
when is the third stage of labor?
birth to expulsion of the placenta - hemodynamic change - no more than 30 min or less
when is the fourth stage of labor?
first few hours after birth
when does a nurse use leopold’s maneuvers?
routinely when preparing fetal monitoring
what does the first maneuver consist of?
assess part of the fetus in the upper fundus
what does the second maneuver consist of?
assess location of the fetal back
what does the third maneuver consist of?
identifying presenting part
what does the fourth maneuver consist of?``
determine descent of presenting part - fetal attitude → feel both sides until hitting cephalic prominence
who performs the fourth leopold maneuver?
Only done by midwife or MD
what are the two ways to monitor fetal heart rate?
external FHR monitoring and internal FHR monitoring
what does external fetal monitoring consist of?
ultrasound is placed over fetal back - external on mother’s belly
what 3 things can interfere with external fetal monitoring?
maternal obesity, excessive fetal or maternal movement, and fetus in OP position (baby’s back faces back)
what does internal fetal monitoring consist of?
a fetal scalp electrode is attached to presenting part of fetus
who can perform an internal fetal monitoring test?
a nurse that has passed a competency test to do so
what is the risk of internal fetal monitoring?
it acts as another avenue for infection
what are the 2 necessary criteria in order for a woman to be eligible for internal fetal monitoring?
woman must be dilated to at least 2 cm + have ruptured membranes
T/F A nurse can rupture membranes.
FALSE!! We have to call an MD to rupture membranes.
what are the two ways to monitor uterine contractions?
external UC monitoring and internal UC monitoring
what does external UC monitoring consist of?
a tocodynamometer is place on woman’s fundus, which measures frequency and durationg of uterine contraction
T/F the tocodynamometer also measures intensity of a UC.
FALSE - only frequency and duration
what 2 things can interfere with external UC monitoring?
maternal obesity and excessive maternal movement
what does internal UC monitoring consist of?
intrauterine pressure catheter inserted through cervix into uterus pocket of fluid, measuring UC intensity
what are the 2 necessary criteria in order for a woman to be eligible for internal UC monitoring?
woman must be dilated to at least 2 cm + have ruptured membranes
Define “fetal heart rate”
the average FHR during a 10 minute period
