Q

the most important fetal structure in relation to labor and birth

A

fetal skull

  • diameters must be small enough to allow the head to travel through the bony pelvis
  • molding- the process where the cartilage between the bones allows the bones to overlap during labor.
  • molding allows the fetal skull to elongate ultimately reducing the diameter of the head

81
Q

The pain of labor and birth is unique to the woman giving birth. It is a multidimensional experience consisting of many factors. What is one of those factors?

a. The number of generations in the woman’s family who are living
b. The significant other’s ability to cope
c. The woman’s culture
d. The societal association of the significant other’s family

A

Rationale: Many factors influence the pain of labor and birth, making it a multidimensional experience. Examples of psychosocial influences include the level of the woman’s fear and anxiety, her culture, and the circumstances surrounding the birth experience, such as whether the pregnancy is planned or unplanned, the child is wanted or unwanted, the birth is preterm or term, and the fetus is living or dead.

82
Q

pain management during labor should be

A
  • planned

- implemented

83
Q

principles of pain relief during labor

A
  • women are more satisfied when they have control over the pain experience
  • caregivers commonly underrate the severity of pain
  • women who are prepared for labor usually report a more satisfying experience than do women who are not prepared
84
Q

non-pharmacologic pain interventions

A
  • continuous labor support
  • comfort measures
  • relaxation techniques: patterned breathing, attention focusing (imagery), movement and positioning, touch and massage, water therapy, hypnosis, intradermal water injections, acupressure (noninvasive form of massage), acupuncture (Use of needles)
85
Q

advantages and disadvantages of non-pharmacologic interventions

A
  • advantages: noninvasive, address emotional and spiritual aspects of birth, promote women’s sense of control over pain.
  • disadvantages: many of the interventions require special training and/or practice before birth, these methods are not effective for every woman.
86
Q

analgesia and sedation

A
  • the use of medication to reduce the sensation of pain
  • sedatives given to promote sedation and relaxation
  • opioids given to provide analgesia during labor
87
Q

anesthesia

A
  • the use of medication to partially or totally block all sensation to an area of the body
  • local, regional, general
88
Q

advantages and disadvantages of opioid administration

A

-advantages: an increased ability for a woman to cope with labor, the medications may be nurse-administered. Examples: Meperidine (demerol) and fentanyl (sublimaze)
-disadvantages: frequent occurrence of uncomfortable side effects, such as nausea and vomiting, pruritus, drowsiness, can cross the placenta and cause fetal heart tone changes and neonatal depression. pain is not eliminated completely
Can ultimately cause maternal death by aspiration, inadequate ventilation and overdosage.

89
Q

used to numb the perineum just before birth to allow for episiotomy and repair

A

local anesthesia

90
Q

involves blocking a group of sensory nerves that supply a particular organ or area of the body

A

regional anesthesia

91
Q

not used frequently in obstetrics because of the risks involved

A

general anesthesia

92
Q

types of regional anesthesia

A
  • pudendal block
  • paracervical block
  • epidural anesthesia
  • intrathecal anesthesia
93
Q

pudendal block

A
  • given just before the baby is born to provide pain relief for the birth.
  • physician injects a local anesthetic bilaterally into the vaginal wall to block pain sensations to the pudendal nerve.
  • helpful for instrument-assisted deliveries and repair of an episiotomy.
94
Q

paracervical block

A
  • involves injection of a local anesthetic in the area close to the cervix.
  • can’t be used once the cervix is completely dilated and has a short duration of action.
  • advantage: it does not block sensation and movement in the lower extremities.
95
Q

epidural anesthesia

A
  • provides excellent pain relief, often completely blocking pain sensation.
  • placed by anesthesiologist or CRNA.
  • intrathecal injection (spinal block)- a one-time dose of medication is placed into the spinal fluid.
  • combined epidural/intrathecal allows pain relief until the epidural begins to work because the intrathecal works immediately
96
Q

complication with epidural and spinal anesthesia

A
  • hypotension
  • maternal fever
  • shivering
  • pruritus (Itching)
  • inadvertent injection into the blood stream
  • spinal headache
  • fetal distress
97
Q

general anesthesia ………………

A
  • not used frequently
  • risk of aspiration
  • general anesthetic agents cross the placenta and can result in the birth of a severely depressed neonate who requires full resuscitation.
98
Q

life threatening complications occurring with general anesthesia

A
  • failed intubation

- malignant hyperthermia

99
Q

T or F: Malignant Hyperthermia is a potential complication of general anesthesia that has genetic origins.

A

True

Rationale: Malignant hyperthermia is a rare, but potentially life-threatening complication of general anesthesia. It is an inherited condition that causes sustained muscle contractions in the presence of certain anesthetic agents.

100
Q

role of LPN during labor and delivery

A
  • recognize and manage complications that may arise during the process
  • give intensive support to the laboring woman and her partner or coach
  • facilitate the labor process and ensure safe passage of the laboring woman and fetus through the event
101
Q

nurse’s role during admission

A
  • immediate assessments: birth imminence, fetal and maternal status, risk factors.
  • additional assessments if birth is not imminent: maternal health history and physical assessment, status of labor, labor and birth preferences
102
Q

components of the admission health history

A
  • obstetric history
  • current status
  • med-surg history
  • social history
  • desires/plans for labor and birth
  • desires/plans for newborn
103
Q

labor status

A
  • assess contraction pattern
  • determine fetal lie, presentation, attitude using Leopold’s maneuver
  • determine cervical dilatation/effacement and fetal position and station with vaginal examination
104
Q

birth plans usually include request regarding

A
  • mobility
  • IV fluids
  • episiotomy
  • presence of friends/family
  • fetal monitoring
  • pain management
105
Q

routine admission orders

A
  • perineal shave prep
  • fleet enema in membranes are intact
  • fetal/uterine monitoring
  • IV access
  • lab work
106
Q

admission labs …………….

A
  • CBC
  • blood type and Rh factor
  • serologic studies, such as VDRL or RPR to test for syphilis
  • rubella titer (not done if prenatal record indicates the woman is immune)
  • ELISA to detect HIV antibodies (requires informed consent)
  • vaginal or cervical cultures
  • urinalysis (clean-catch specimen)
107
Q

Mrs. Jones , a G4 P3, has just come in to the labor and delivery suite. She tells the admission nurse that her water broke 2 hours ago and she feels like pushing. What is the first assessment the nurse should make?

a. Maternal vital signs
b. Imminence of birth
c. Take an obstetric history
d. Find a good vein and start an IV

A

b. Imminence of birth

Rationale: Nursing assessment for signs that birth is imminent begins from the moment the woman arrives in the labor and delivery unit. If the woman is introverted and stops to breathe or pant with each contraction, you can infer that she is in an advanced stage of labor. In addition, if the woman makes statements such as, “I feel a lot of pressure,” or “The baby is coming,” or “I want to have a bowel movement,” it is likely the woman is in the second stage of labor, and the baby will be born soon.

108
Q

monitoring uterine contractions : external methods

A
  • palpation to evaluate the contraction pattern: mild contraction- fundus feels like the tip of your nose at the peak of a contraction. moderate contraction-fundus feels like touching your chin. strong contraction- feels like you are pushing on your forehead.
  • toco measures contraction frequency and duration
109
Q

monitoring uterine contractions : external methods …………….

110
Q

intermittent auscultation of FHR ………………

A
  • acceptable method in low-risk pregnancy
  • most common practice: place external fetal monitor for 20 minutes to get baseline data
  • if pattern is reassuring, then fetoscope or external monitor used intermittently
  • auscultate fetal heart rate
  • any concerns: attach continuous EFM
111
Q

advantages of internal auscultation FHR.

A
  • woman has more freedom to move about

  • associated with fewer medical interventions and fewer surgical deliveries
112
Q

disadvantages of internal auscultation FHR

A
  • takes more time
  • requires higher nurse staffing levels
  • many practitioners unaccustomed to using IA fear the potential of missing an ominous FHR pattern.
113
Q

external EFM : indirect

A
  • most common way to assess fetal status during labor
  • works on the principle of ultrasound
  • characteristics of the fetal heart rate pattern can then be monitored continuously via a video display and/or a continuous printout
  • toco monitors the contraction pattern
  • helps screen for signs of fetal compromise
  • sometimes it is difficult to get a consistent tracing if the fetus is small or extremely active, or if the woman is obese
  • uncomfortable
  • some manufacturers of fetal monitors have developed telemetry units
114
Q

internal EFM

A
  • invasive procedure
  • spiral electrode is attached to the presenting part just under the skin
  • records a graphic representation of FHR
  • easier to obtain consistent tracing
  • increases the risk of maternal and fetal infection and injury
115
Q

baseline FHR

A
  • measured between uterine contractions during a 10-minute period
  • normally accepted baseline rate is between 110 beats per minute (bpm) and 160 bpm
  • baseline variability: fluctuations of the FHR from the baseline rate
116
Q

fetal tachycardia

A

greater than 160

117
Q

fetal bradycardia

A

below 110

118
Q

three major deviations form a normal FHR baseline

A

-tachycardia: greater than 160
-bradycardia: below 110 bpm
-absent or minimal: non reassuring pattern
MUST CONTINUE FOR ATLEAST 2 MINS

119
Q

…………………….. are variations in the FHR pattern that occur in conjunction with uterine contractions .

A

periodic changes

120
Q

……………………….. are variations in the FHR pattern NOT associated with uterine contractions .

A

episodic changes

121
Q

reassuring periodic changes

A

accelerations above the baseline by at least 15 bpm for at least 15 seconds (15 x 15 window)

122
Q

benign periodic changes

A

early decelerations

123
Q

non reassuring periodic changes

A
  • variable decelerations indicating some type of acute umbilical cord compression
  • late decelerations indicating uteroplacental insufficiency
124
Q

measures used to clarify nonreassuring FHR patterns

A
  • fetal stimulation: acoustic vibrator, scalp stimulation
  • fetal scalp sampling: small blood sample obtained from scalp
  • fetal scalp pulse oximetry: sensor placed next to fetal cheek or temple
125
Q

T or F : Early decelerations are benign periodic changes.

A

True

Rationale: Sometimes instead of accelerations, there is a slowing of the FHR. If the dip in the FHR tracing occurs in conjunction with and mirrors a uterine contraction, it is an early deceleration. As long as the baseline remains within normal limits and the variability is good, early decelerations are benign.

  • measure L/S ratio by amniocentesis
164
Q

methods of cervical ripening

A
  • mechanical: membrane stripping, inserting a catheter into the cervix and inflating the balloon, cervical dilators (laminaria)
  • pharmacologic: prostaglandin E2 (dinoprostone), prostaglandin E1 (misoprostol)
  • artificial rupture of membranes (AROM) : also called amniotomy causes the body to release prostaglandins, which enhances labor.

A

False

Rationale: There are two main preparations, but the only substance approved by the United States Food and Drug Administration (FDA) for this purpose is prostaglandin E2 gel or vaginal inserts (dinoprostone). Prostaglandin E1 (misoprostol) is used frequently for cervical ripening, although it is not approved for this use.

184
Q

fetal complications of cesarean birth

A
  • most common is unintended delivery of an immature fetus because of miscalculation of dates and respiratory distress because of retained lung fluid
  • depressed fetal respiratory drive, due to anesthesia, makes it difficult for the newborn to take his or her first breath
  • fetal injury can occur
185
Q

  • postoperative phase: LPN can assume care of woman after she has sufficiently recovered from anesthesia
187
Q

nursing care in cesarean birth

A

planned cesarean birth
-focus on education to prepare the family for the birth
emergency cesarean birth
-focus on supportive behaviors: explaining procedures as they are done, providing appropriate reassurance
providing care in immediate postoperative period
-many contributing factors

188
Q

A cesarean delivery is a major surgery and requires a team approach to caring for the pregnant woman. During the intraoperative period of a cesarean delivery, what is the role of the LVN/LPN?

a. Take vital signs every 15 minutes
b. Provide reassurance to the mother and significant other
c. Act as a scrub nurse if trained appropriately
