Q

What three things do you need to assess during a contraction?

A

○ Frequency
■ Start of one contraction to the start of another
■ Adequate active labor contractions are q2-5 minutes
■ Generally become more frequent in active labor q2-3 minutes
○ Duration
■ Start to finish of one contraction (last at least 40 seconds)
○ Strength
■ Depends on type of contraction monitoring
■ Can be palpated externally by placing a hand on the fundus during a contraction
● Classified as mild, moderate, or strong
■ Can only be measured with an internal contraction monitor (IUPC) (mmHg)

Q

Intermittent Auscultation

  • One Benefit
  • When to Assess Heart Rate
  • When to NOT use
  • Performed how frequently? (early labor, active labor, second stage)
A
  • Benefit:

Freedom of movement for the laboring person

  • When to Assess Heart Rate

Assess fetal heart rate BEFORE, DURING, and especially AFTER a contraction

Q

What is variability?

What is the difference in rate between: Marked, Moderate, Minimal, and Absent:

A

It the average fluctuations of the heart rate (beats to beat)

  • Marked (> 25bpm) SELDOM SEEN,
  • Moderate (6-25bpm) IDEAL

Minimal (1-5bpm) Potential sign of fetal distress

  • Absent (flat line)- Very concerning- NEED to deliver
  • *Note: variability is the best indicator of fetal oxygenation status*

Q

What is a bishop’s score done by provider? Above and below 8 indications:

A

If score is below 8 then cervical ripening is needed
* have to use chemical methods (both prostaglandins that cause mild contractions)
*mechanical methods just force cervix to dilate (balloon or laminara)
If score is above 8- then you can go straight to inductions and start oxytocin

134
Q

A nurse is caring for a client during a non stress test (NST). At the end of a 30 min period of observation, the nurse notes the following findings : the fetal HR baseline is 120/min with minimal variability and no accelerations. There are two decelerations of 15/min in the fetal HR during a period of fetal movement, each lasting 20 seconds. Which of the following interpretations of these findings should the nurse make?

A

A nonreactive test

Rationale: an NST that does not produce two more qualifying accelerations within a 20 minute period is interpreted as nonreactive. Qualifying accelerations peak at least 15/min above the FHR baseline and last at least 15 seconds.

135
Q

A nurse in the L&D unit is caring for a client who is undergoing external fetal monitoring. The nurse observes that the fetal heart rate begins to slow after the start of a contraction and the lowest rate occurs after the peak of the contraction. Which of the following actions should the nurse take first?

A

Place the client in the lateral position
Rationale: this is a late deceleration and is associated with fetal hypoxemia due to insufficient placental perfusion. Placing the client in the lateral position is the first action the nurse should take.

136
Q

Placenta Abruption

Recognize and assess complaints of bleeding, pain, or rupture of membranes,
notify provider, work with team if plan is to deliver, follow protocols

139
Q

Placenta Abruption

A

● Premature separation of the placenta from the uterine wall
● Majority of deliveries still occur vaginally
● Marginal or complete; acute or chronic
● Risk factors: uncontrolled hypertension, trauma, drug use (cocaine)
● Moderate-severe separation can lead to shock, DIC, and emergency cesarean

140
Q

Placenta Previa

● Von Willebrand disease: form of hemophilia○ Most common congenital bleeding disorder
● Disseminated intravascular coagulopathy (DIC) (rare abnormal blood clotting thruout vessels)
● All require close monitoring of labs
● May require platelet or plasma transfusion
● 1 of the 4T’s discussed later as a cause of postpartum hemorrhage (Thrombin!)

142
Q

Previa vs Abruption

A
  • *Previa** is painless uterine bleeding and location of placenta
  • *Abruption** is painful uterine bleeding and separation of uterine wall/ acute
143
Q

Do we deliver the patient with placental previa or abruption conditions as soon as the patient complains of bleeding?

A

In both cases, bleeding does not always result in immediate delivery!

144
Q

Placenta Accreta/Percreta/Increta: What is it? How is it diagnosed?

A

● Abnormal placental attachment beyond the endometrium○ Diagnosed via ultrasound in pregnancy
● Not clinically important until delivery → Plan for cesarean

● 2nd and 3rd trimester: Assume all bleeding is due to a placenta previa

****NO pelvic exams until identify placental location!

149
Q

Vasa Previa:

A

● Fetal vessels on outer surface of placenta exposed
● Want to avoid spontaneous labor at all costs
