3
When monitoring FHR, the nurse notices that periodically, the fetus' heart rate rises above baseline for brief periods of time. What is this called and what does it mean?
Accelerations It means that the baby is doing well and is well oxygenated
The physician suspects that a pregnant patient's membranes have ruptured. The physician dips a Q-tip in the vaginal fluid, and then swipes the q-tip across Nitrazine Paper. The paper turns a purple/blue color. This result confirms that the vaginal fluid is what?
Amniotic Fluid
What are the two most important nursing assessments that should be performed after ROM?
Assess the FHR: (risk of umbilical cord prolapse). Assess the Amniotic Fluid for Color, Amount and Odor
fetus with respect to the birth canal is critical. What is the relationship of the fetal head to the rest of the body-vertex, brow or military, face. (similar to presentation)
Attitude
________________ is a premonitory sign of labor and is when the woman may experience a brownish or blood-tinged cervical mucus discharge
Bloody Show.
The Nurse notices variables in FHR. She knows that this is caused by what? and what interventions should she put in to place?
Cord Compression turn mom on left side and give her oxygen. usually 8-10 liters per min. If patient on Pitocin. STOP it
Name the Cardinal Movement of labor: downward progress of the fetus through the pelvis. Movement of the fetus through the birth canal during the first and second stages of labor.
Descent
List the 8 cardinal movements of labor!
Descent Flexion Engagement Internal Rotation Extension Restitution External Rotation Expulsion
When monitoring FHR, the nurse notices that the Fetus' heart rate drops, beginning with a contraction and goes back up when the contraction ends. The nurse knows that this is called ________________? What nursing intervention should she put into place?
Early Decelerations No Interventions, just continue to monitor
Name the Cardinal Movement of labor: widest diameter of the presenting part is at the level of the ischial spines ("0" station). When the greatest diameter of the fetal head passes through the pelvic inlet; can occur late in pregnancy or early in labor.
Engagement
Name the Cardinal Movement of labor: delivery of the rest of the infant. The shoulders and remainder of the body are delivered.
Expulsion
Name the Cardinal Movement of labor: anterior deflection of the fetal head when it reaches the floor of the perineum. Facilitated by the 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.
Extension
Name the Cardinal Movement of labor: shoulder rotation to an anterior - posterior position. During this movement, the sagittal suture moves to a transverse diameter and the shoulders align in the anteroposterior diameter. The sagittal suture maintains alignment with the fetal trunk as the trunk navigates through the pelvis.
External Rotation
Is the following a sign of true labor or false labor? Contraction felt in the Abdomen and fundus
False Labor
Is the following a sign of true labor or false labor? Contractions decrease in intensity with activity and walking
False Labor
Is the following a sign of true labor or false labor? Contractions have irregular pattern
False Labor
Is the following a sign of true labor or false labor? No cervical Change
False Labor
Is the following a sign of true labor or false labor? Contraction felt mostly in abdomen or fundus
False Labor.
fetus with respect to the birth canal is critical. What is the relationship of the long axis of the fetus to the long axis of the mother known as ?
Fetal lie
Name the Cardinal Movement of labor: normal position assumed by the fetus due to shape of the uterus. 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.
Flexion
The nurse knows that Early Decelerations in FHR is caused by what ?
Head Compression
When Monitoring fetal heart rate of a term fetus, the nurse notices that the fetus' heart rate is bradycardic (consistently), what is the first things he suspects What can she anticipate to do next ?
Hypoxia or Hypoxemia Apply Oxygen and begin IV fluid bolus
fetus with respect to the birth canal is critical. What is the Relationship of a reference point on the baby to the maternal pelvis known as?
Position
Name the Cardinal Movement of labor: rotation of the fetal head from transverse to anterior position. Usually starts at level of ischial spines. When the rotation of the fetal aligns the long axis of the fetal head with the long axis of the maternal pelvis; occurs mainly during the second stage of labor.
Internal Rotation
_____________________ is a premonitory sign of labor and refers to the descent of the fetus into the true pelvis that occurs approximately 2 weeks before term in first-time pregnancies. The woman may feel she can breathe more easily but may experience urinary frequency from increased bladder pressure.
Lightening
What are the premonitory signs of Labor
Lightening Braxton-Hicks Contractions Surge in Energy Cervical Changes Gastrointestinal Changes Backache Bloody Show
