Intrapartal Nursing Flashcards
Duration
Beginning of contraction (muscle begins to tense), to the end of same contraction (muscle is completely relaxed)
Frequency
Beginning of one contraction to the beginning of the next
Uterine resting tone
Between uterine contractions when optimum uterine relaxation is achieved
Acme or peak
Intensity is evaluated subjectively by estimating firmness (nose, chin, four head= mild, moderate, and strong)
Early or Latent phase of labor
0 to 3 cm, relaxed, excited, anxious
Active phase of labor
4 to 7 cm, more intense, begins to tire
Transitional phase of labor
8 to 10 cm, feel tired, unable to cope, needs frequent coaching to maintain breeding patterns
Electronic monitoring with external toco
Can determine frequency and direction, cannot determine intensity, may be used BEFORE and AFTER ROM rupture of membranes, placed over fetal part of fundus on outside of abdomen
Internal uterine pressure catheter (IUPC)
Inserted into uterine cavity of cervical os, place in area of fetal small parts, can only be used AFTER ROM ruptured membranes, measures resting tone of uterus between contractions, measure actual pressure during contractions – intensity
Advantage – critical in woman attempting vaginal birth to avoid tachysystole and uterine rupture
Leopold maneuver position
Bladder empty
Lie on back with abdomen uncovered, shoulders race lightly on pillow, knees drawn up a little
Completed between contractions
Determines lie – longitudinal or transverse
Fetal scalp electrode – FSE – internal monitoring
Most precise method of monitoring EKG of FHR, attached to fetus during vaginal exam
Cervix must be 2 cm dilated, pedal car presenting, are ROM
Avoid in preterm infants because increased risk of ventricular hemorrhage
Baseline fetal heart rate
Must be at least two minutes of identical baseline segments and any 10 minute window
Acceleration deceleration or periods of mart fetal heart rate variability are excluded
Fetal tachycardia
BL FH are greater than 160 bpm for at least a 10 minute.
Variable deceleration
Decrease in fetal heart rate – defined as onset of the deceleration to beginning of fetal heart rate made her a 30 seconds or less
Decrease in fetal heart rate 15 beats a minute, lasting 15 seconds or more, in less than two minutes duration
Prolonged deceleration
Decrease in fetal heart rate of 15 beats a minute or more that last more than two minutes and less than 10 minutes
Critical factors in labor
x5
Birth passage Fetus Relationship between birth passage of fetus Physiological forces of labor Psychosocial considerations
Fetal attitude
Posture the fetus assumes as it conforms to the shape of the uterine cavity
-* normal is general flexion: baby ducks head down, presenting the clown
Fetal lie
Relationship of access, spinal column, a fetus to access of mother spinal column
Longitudinal lie
Cephalocaudal access of the feudal spine is parallel to one months time
Transverse lie
Cephalocaudal access of the fetal spine is at a right angle to the woman spine
- cause shoulder presentation
- Csection
Fetal presentation
Determined by fetal lie, body part a fetus that enters maternal pelvis first, “presenting part” felt through cervix on vag exam
Cephalic (head first), breech (buttocks or feet first), or shoulder (malpresentation)
Vertex presentation
Most common
fetal head completely flexed
Smallest diameter presents
*Occiput is landmark
Sinciput presentation
Fetal head partially flexed
Top of head is presenting part
Occiptofrontal diameter presents
*Occiput is landmark
Brow presentation
Head partially extended
Occipitomental diameter/ LARGEST anterioposterior diameter presented
* Chin is landmark
Face presentation
Head is hyper extended
Submentobregmatic diameter
*Chin is landmark
Complete breech
Head and knees flexed,thighs on abdomen
Cavs on posterior aspect of thighs
Buttocks and feet present
* sacrum is landmark
Frank breech
Hips flexed, knees extended
Buttocks presents
* sacrum is landmark
Footling breach
Hips and knees extended
Feet present
Single footling, double footling
* sacrum is landmark
