Q

Dystocia: What is this?

A

Defined as abnormal or difficult labor, and can be influenced by a vast number of maternal and fetal factors. Said to exist when progress of labor deviates from normal and is a slow/abnormal progression of labor

2
Q

A

Lack of progressive cervical dilation, lack of descent of the fetal head, or both

3
Q

Dystocia: What factors are associated with increased risk for dystocia?

A

Epidural analgeisa, excessive analgesia, multiple pregnancy, hydramniois, maternal exhaustion, ineffective maternal pushing technique

4
Q

Dystocia: Most common indications for primary cesarean births include what?

A

Labor dystocia, abnormal FHR tracing, fetal malpresentation, multiple gestation, and suspected macrosomia

5
Q

Dystocia and Problems with Powers: What happens when the expulsive forces of the uterus become dysfunctional?

A

Uterus may either never fully relax (hypertonic contractions), placing fetus in jeopardy, or relax too much (hypotonic contractions) causing ineffective contractions

6
Q

Dystocia and Problems with Powers: What can occur when uterus contracts so frequently?

A

Rapid birth will take place (precipitate labor)

7
Q

Dystocia and Problems with Powers: When does hypertonic uterine dysfunction occur?

When the uterus never fully relaxes between contractions. Contractions are then ineffectual, erratic and poorly coordinated and involve only one portion of uterus.

8
Q

Forceps or Vacuum-Assisted Birth: What is a vacuum extractor?

A

Cup-shaped instrument attached to a suction pump used for extraction of the fetal head. Placed against occiput of fetal head. Pump create neegative traction and uses until fetal head emerges

170
Q

Forceps or Vacuum-Assisted Birth: Why would these be used?

A

Because of prolonged 2nd stage of labor, distressed FHR pattern, failure to rotat, and descent in the pelvis.

171

Q

Forceps or Vacuum-Assisted Birth: How to prevent using these techniques?

A

Frequently change client position, encourage ambulation, remind to empty bladder, and provide adequate hydration

175
Q

Cesarean Birth: What two incisions may be used?

A

Classic (vertical) or low transverse (horizontal) (most common today)

176
Q

Cesarean Birth: What increased risks may the client have because of this?

A

Infection, hemorrhage, aspiration, pulmonary embolism, UTI, thrombophlebitis, and paralytic ileus

177
Q

Cesarean Birth: What may cause a woman to want this?

A

Active genital herpes, fetal macrosomia, fetopelvis disproportion, prolapsed umbilicl cord, and previous classic uterine incision or sccar

178
Q

Cesarean Birth: What preoperative procedures may be done for this?

A

Prepare the surgical site

Start IV infusion for fluid replacement

Insert an indwelling foley catheter

ADminister any preop medsd

179
Q

Cesarean Birth: How often will VS be assessed?

A

Every 15 mins for first hour

30 mins for next hour

Then every 4 hours if stable.

180
Q

Cesarean Birth: Wy would you provide early ambulation?

A

To prevent respiratory and cardiovascular problems and to promote peristalsis

181
Q

When reviewing the medical record of a client, the nurse notes that the woman has a condition in which the fetus cannot physically pass through the maternal pelvis. The nurse interprets this as:

Client with a history of a previous preterm birth
A

Client with history of previous preterm birth

185
Q

Prevent cervical lacerations
Soften and efface the cervix
A

Soften and efface the cervix

186
