| Strength of the contraction. It is evaluated with palpation using the fingertips on maternal abdomen and is described as mild, moderate, or strong. |

| Moderate intensity during contraction |
|
Definition
| The uterine wall is resistant to indentation during contraction. |

|
Definition
| The uterine wall cannot be indented during contraction. |
|
|
Term
|
Definition
| refers to the relationship of the ischial spines to the presenting part of the fetus and assists in identifying for fetal descent during labor. 0 is the narrowest diameter the fetus must pass through during vaginal birth. |
|
|
Term
| Braxton Hicks contractions |
|
Definition
| irregular UC's that do not result in cervical change and are assoicated with false labor. |
|
|
Term
| Cardinal movements of labor |
|
Definition
| positional changes the fetus goes through to best navigate the birth process |
|
|
Term
|
Definition
| when the greatest diameter of the fetal head passes through the pelvic inlet; can occur late in pregnancy or in early labor. |
|
|
Term
|
Definition
| Irregular or regular mild contraction with no increase in frequency, intensity or duration |
|
|
Term
|
Definition
| Discomfort felt in the middle of the abdomen or groin area. Can me mentally and physically tiring. |
|
|
Term
|
Definition
| Regular contractions that increase in frequency, intensity, and duration. |
|
|
Term
|
Definition
| Discomfort begins in the back and radiates to the lower abdomen in the front. |
|
|
Term
|
Definition
| Little or no cervical change |
|
|
Term
|
Definition
| Progressive cervical dilation and effacement |
|

|
Definition
|
|
Term
|
Definition
| Bloody show: usually present and increases with cervical changesTR |
|
|
Term
|
Definition
| Activity or position change often lessens contractions |
|
|
Term
|
Definition
| Activity such as walking may increase intensity of contraction |
|
|
Term
|
Definition
| movement of the fetus through the birth canal during the first and second stage of labor. |
|
|
Term
|
Definition
| When the chin of the fetus moves toward the fetal chest; occurs when the descending head meets resistance from maternal tissues; results in the smallest fetal diameter to the maternal pelvic dimensions; normally occurs early in labor. |
|
|
Term
|
Definition
| When the rotation of the fetal head aligns the long axis of the fetal head with the long axis of the maternal pelvis; occurs mainly during second stage of labor |
|
|
Term
|
Definition
| facilitated by resistance of the pelvic floor that causes the presenting part to pivot beneath the pubic symphysis and the head to be delivered; occurs during the second stage of labor. |
|
|
Term
|
Definition
| During this movement, the sagittal suture moves to a transverse diameter and the shoulders align in the anteroposterior diameter. The sgittal suture maintains alignment with the fetal trunk as the trunk navigates through the pelvis |
|
|
Term
|
Definition
| The shoulders and remainder of the body are delivered |
|
|
Term
|
Definition
| begins with the onset of labor and ends with complete cervical dilation. |
|
|
Term
|
Definition
| begins with compelte dilation of the cervix and ends with delivery of the baby. |
|
|
Term
|
Definition
| begins after delivery of baby and ends with delivery of the placenta. |
|
|
Term
|
Definition
| begins after delivery of the placenta and is completed four hours later; it is the immediate postpartum period. |
|
|
Term
|
Definition
| tracings are normal; predictive of a well oxygenated, nonacidotic fetus with a normal fetal acid-base balance. |
|
|
Term
|
Definition
| tracings are indeterminate; require evaluation and continued surveillance and revaluation |
|
|
Term
|
Definition
| is predictive of abnormal fetal acid-base status and requires prompt evaluation |
|
|
Term
|
Definition
| most predictor of adequate fetal oxygenation during the labor; fluctuations in the baseline FHR that are irregular in the amplitude and frequency. |
|
|
Term
1. FHR Baseline
2. Periodic and episodic changes
3. Uterine Activity |
|
Definition
| 3 major areas assessed when interpreting FHR pattern: |
|
|
Term
|
Definition
|
|
Term
|
Definition
| Amplitude range is undetectable |
|
|
Term
|
Definition
| Amplitude range is undetectable < or equal to 5 bpm range |
|
|
Term
|
Definition
| Amplitude from peak to trough 6 bpm to 25 bpm |
|
|
Term
|
Definition
| Amplitude range greater than 25 bpm |
|
|
Term
|
Definition
| tachycardia (early sign) with decreased variability and decelerations |
|
|
Term
| which causes a decrease in umbilical blood flow that leads to decreased oxygen to the fetus, causing fetal hypoxia (loss of variability or late develerations) |
|
Definition
| A decreased FHR (brady) can lead to decreased cardiac output... |
|
|
Term
| can happen during fetal sleep cycle, or can be a sign of fetal hypoxia or acidosis |
|
Definition
|
|
Term
|
Definition
| accelerations or decelerations in FHR that are in relation to uterine contractions and persist over time |
|
|
Term
|
Definition
| accelerations or decelerations in patterns not associated with contractions (accelerations most common_ |
|
|
Term
|
Definition
| lowest part of the deceleration; occurs at the peak of the contraction |
|
|
Term
| early deceleration (fetal head compression; benign, no intervention necessary) |
|
Definition
| visually apparent, usually symmetrical, with a gradual decrease and return of FHR associated with UC |
|
|
Term
|
Definition
| a visually apparent abrupt decrease in the FHR (could be caused by chord compression) |
|
|
Term
|
Definition
| visually apparent symmetrical gradual decrease of FHR associated with UC's. |
