(3) Exam 2-🍼 Timing Contractions & Client Teaching Flashcards
What must occur with any internal monitoring?
Rupture of the membranes (Water has to break)
External Fetal Monitor (Topa Monitor) is placed at the top of the fundus and the lower monitor is placed where?
Where the baby’s back is.
What method to assess uterine activity requires screws going into the baby’s head?
Internal Scalp Electrode Monitor
What is frequency?
Measurement from the beginning of one contraction to the beginning of another.
Frequency is measured using what unit of time?
Minutes
What is duration?
How long a contraction lasts from start to end.
Duration is measured using what unit of time?
Seconds
What uterine activity is measured by palpating the firmness of the abdomen and cant be determined by monitoring unless an IUPC is used?
Intensity
What goes into the uterine cavity to determine the exact strength of contractions?
Intrauterine Pressure Catheter (IUPC)
When reading the fetal monitor to determine uterine activity, how is one minute represented?
Red Line to Red Line = 1 minute
When reading the fetal monitor tracing strip to determine uterine activity, what does a small box represent?
10 seconds
What is tachysystole?
Contraction every minute to two minutes averaged over a 30 minute time frame
What is reflective of fetal oxygen status?
FHR
How does the sympathetic and parasympathetic system control the FHR?
Parasympathetic decreases the FHR and Sympathetic increases the FHR
What is the normal range for a FHR?
110-160 bpm
When do you assess the FHR to determine a baseline?
Between contractions
What is the most important aspect of predicting the fetal status and is a predictor of the baby’s neuro status and how well it is being oxygenated?
Variability
What are the 4 categories of variability?
Marked
Average
Minimal
Absent
Variability >25 is what type of variability?
Marked Variability
What is the range of average variability?
5-25
What is it called when theres an increase of 15 bpm in FHR that stays up for at least 15 seconds?
Accelerations
What is it called when there is a decrease FHR from baseline?
Decelerations
What are the 3 categories of decelerations?
Early
Late
Variable
What type of deceleration mirrors contractions, is caused by fetal head compression and is usually seen at the end stage of labor when pushing begins?
Early Decelerations
In what deceleration does FHR dip down slightly during peak of contraction and return to baseline when contraction is over?
Early Deceleration
What deceleration begins at the peak of contractions, is uniform in shape, and is caused by uteroplacental insufficiency resulting from decreased blood flow and oxygen transfer to the fetus during contractions.
Late Deceleration
What is the first intervention with late decelerations?
Shut Pitocin off
After Patocin is shut off, how is the patient repositioned for better perfusion when late decelerations occur?
Repositioned to the left side.
After Pitocin is shut off and the patient is repositioned, what is the next intervention that is initiated to increase the baby’s O2 and increase fluid around the baby to correct late decelerations?
Increase IV Fluids
When late decelerations occur, oxygen is administered via mask at what rate?
10L
