Q

An insulin dependent diabetic client gives birth, the nurse expects the client’s insulin requirements in the first 24 hrs to what? Why?

A

Drop significantly

Think: The energy needed to recuperate after delivery uses the body’s glucose.

-The placenta causes insulin resistance and is no longer there after delivery

A

-Preeclampsia that has progressed to tonic-clonic seizures

-HELLP Syndrome: Part of PIH
Hemolysis of RBC’s, [H}
Elevated liver enzymes [EL]
Low Platelets [LP]

  • At risk for hemorrhage, pulmonary edema, and hepatic rupture
  • Fetus would show evidence of UPT (Utero-placental insufficiency) with late decelerations
28
Q

A
  • Hypertension > 160/110
  • Proteinuria +3 to +4 or more than 5 in a 24 hr urine sample
  • Sudden large weight gain w/facial edema
  • Pitting pretibial edema
  • Signs of CNS irritation

Risk for: Abruptio placenta

29
Q

What are systemic responses/symptoms to preeclampsia/eclampsia?

A
  • Severe or continuous headache
  • Hyperreflexia > +2 baseline or clonus (Check patellar reflexes
  • Visual disturbances (blurred vision, sports, flashing lights)
  • Oliguria (signals renal damage)
  • Portal hypertension signaled by epigastric pain and indicator of seizure and hepatic rupture
30
Q

What is clonus?

A

involuntary muscle contractions

31
Q

What Rx is given for severe preeclampsia?

A

Magnesium sulfate

32
Q

How will the nurse assess for clonus/hyperreflexia?

A
  • Checking the patellar reflexes
  • Dorsiflex the foot, when there is hyperreflexia the foot will jerk
  • Each movement or jerk is counted, so 2 beats of clonus means there were two movements after the foot is dorsiflexed
33
Q

What lab values will you see in PIH/Preeclampsia/Eclampsia?

A

Increased HCT
Elevated BUN and serum uric acid
Increased liver enzymes (ALT and AST)
Decreased RBCs and platelets

34
Q

What is the care for the Antepartum Preeclamptic?

A
  • Bedrest at home or hospital
  • Decrease neuro stimulus meaning, quiet room, low light, anything to decrease CNS and prevent seizures
  • High protein diet W/O salt restriction or diuretics
  • Foley if hospitalized to check output

-Need amniocentesis to check L:S ratio for early
delivery (determining factor in fetal lung maturity)

-Serial NST’s for fetal well being

35
Q

Describe the Rx of choice for PIH/Preeclampsia/Eclampsia. What does it do? what is the antidote?

A

Mag sulfate :
-Used for seizure prevention (**osmotic diuretic **preventing convulsions pulls fluid from the brain)

  • Normal level is 5-8 mg, anything > 8 is toxic
  • Relaxes everything so check for LOC, output, RR, etc
  • Antidote is calcium gluconate
36
Q

Describe the loading dose for magnesium sulfate.

A
  • High dose to stabilize
  • Normal loading dose 4-6 gm in 20% solution via IV pump over 15-20min.
  • Maintenance dose is 2 gm/hr IV pump
  • This would be piggybacked on mainline so if stopped you have open up main line.
37
Q

What are three signs of magnesium toxicity?

A
  • Diminished or absent reflexes
  • Depressed respirations
  • Marked lethargy
38
Q

What are other antihypertensive Rx’s and the one for lung development in fetuses?

A
  • Procardia and labetalol(Normodyne) or Apresoline
  • Sedation with phenobarbital or valium
  • bethamethasone to women whose fetus has immature lung profile
39
Q

What is the cure for a laboring woman with PIH/Preeclampsia/Esclampsia? What simple intervention should you do until then?

A
  • Only cure is delivery, usually C-section

- Keep on left side to increase uterine placental perfusion until ready to section

40
Q

Describe what happens postpartum to the PIH/Preeclampsia/Esclampsia PT.

A

Comes back with two drips, Mag Sulfate to prevent seizures that could happen with 48 hrs and Pitocin to counteract the relaxing capacities of mag sulfate so the uterus firms up.

-Newborn should be watched for signs of cardiac ad respiratory depression due to mag sulfate

41
Q

What is Premature Rupture of Membranes?

A
  • Amniotic membrane rupture before labor begins, will usually begin spontaneously within 24 hrs of rupture
  • Preterm rupture is prior to term gestation or 38 weeks and is driven by infection, incompetent cervix and trauma
42
Q

What is prolonged rupture of the membranes?

A
  • Membranes ruptured more than 12 hrs before birth without labor
  • Given oxytocin
43
Q

What is a major issue with membrane rupture? What would you do?

A

Prolapsed cord

Get woman off cord on left side with hips elevated

44
Q

If preterm and membranes rupture what would the nurse do? When must you deliver?

A
  • Will put to bedrest
  • Head down, legs up; foley in
  • Antibiotics for infection risk (ampicillin)
  • Fetal monitoring
  • Might see amniofusion
  • Obtain cultures for group B strep

-If there is maternal temp then MUST deliver
(might see increased WBCs, abdominal tenderness)

45
Q

What are Hemorrhagic pregnancy complications?

A
  1. Ectopic pregnancy
  2. Preterm labor
  3. Placenta Previa (placenta on bottom of cervix)
  4. Abruptio Placenta (usually from trauma)
  5. Postpartum Hemmorhage (usually from mag sulfate
    or terbutaline, uterus remains boggy)
  6. Uterine rupture
46
Q

Describe Ectopics.

A
  • Sharp UNILATERAL pain; may see abdominal rigidity with referred right shoulder pain
  • Usually seen in ER and most common implantation site is fallopian tube
  • Triggered by hx of ascending infections and IUD contraceptive use
  • Ultrasound confirms extrauterine pregnancy, HcG lab test confirms pregnancy*
  • Might see signs of hypovolemic shock
  • Can save tube with use of methotrexate, (Rx that destroys cellular development)
47
Q

Describe Preterm Labor.

A

Contractions occurring between 20-37 weeks gestation

Contractions every 10 minutes or less or without pain

Low abdominal cramping with or without diarrhea

Low backache

Increased vaginal discharge

Leaking amniotic fluid

48
Q

What are immediate actions to do at home for preterm labor?

A
  • Empty bladder
  • Lay on left side
  • Drink 3-4 glasses of water
  • Call HCP
49
Q

What is the medical management of preterm labor?

A
  • Bedrest, preferably left lateral
  • Monitoring

Administration of tocolytic agents which are Rx’s that relax uterus and stop contractions:

> terbutaline IV…oral is brethine
magnesium sulfate
ritrodrine (Yutopar) not used as much because K+ drops
betamethasone/celestone for lung maturity

50
Q

What are the side effects of terbutaline, magnesium sulfate, ritrodrine(Yutopar), and betamethasone/celestone?

(rx’s used to relax uterus and stop contractions (preterm labor) except betamethasone.

A

terbutaline - nervousness, palpations, maternal or fetal tachycardia, nausea and vomiting, pulmonary edema

ritrodrine(Yutopar) - maternal/fetal tachycardia, SOB, pulmonary edema, hypokalemia, hyperglycemia

betamethasone/celestone - hyperglycemia, risk of pulmonary edema

magnesium sulfate - respiratory depression, decreased LOC, output, CNS

51
Q

Describe Placenta Previa. How are the fetuses delivered? What confirms? What should you never do?

A

Placenta on bottom of cervix. Due to scarring, fibroids, the fertilized ovum implants near or over the internal cervical os

  • Key to this is PAINLESS bleeding WITHOUT contractions
  • Delivery is by C-section
  • Ultrasound to confirm
  • High chance with multigravida or multiparty

NEVER perform a vaginal exam as you can create profuse hemorrhage

52
Q

What is Abruptio Placenta? What is it usually from? Symptom? What confirms? How.is baby delivered?

A

Placenta detaches from the womb.

  • Emergency/Crisis
  • Usually due to trauma, substance abuse (cocaine), PIH
  • Painfully rigid board like abdomen because of bleeding in closed cavity
  • Ultrasound will confirm
  • Emergency C-Section
  • Fetal monitor will show late decelerations, sinussoidal if dying.
  • High chance for amniotic fluid emboli
53
Q

When does postpartum hemorrhage occur due to uterine atony(boggyness) and lacerations?

A

Occurs due to medication such as mag sulfate or terbutaline

Occurs when there’s retained placental tissue

Occurs with multiple births or multiparty

Occurs with low platelets

Occurs with dysfunctional or prolonged labors

Occurs if resident exams uterus post delivery

54
Q

What are the Uterine Stimulants used to prevent and manage uterine atony(boggyness)?

A
    1. oxytocin (Pitocin or Syntocinon) creates mild hypertension
      1. methylergonovine(Methergine) creates hypertension, headache, chest pain, flushing
      2. ergonovine(Ergotrate) hypertension, dizziness
    1. prostaglandin (PGF2, hemabate, Prostin 15M) nausea, vomiting, bradycardia
  • used in example questions
55
Q

Describe Uterine rupture. When can it occur? What is the result? What happens to neonate?

A
  • Can occur with too aggressive Pitocin use
  • Can occur with previous scar tissue from C-section during vaginal delivery
  • Can occur with multiples

Result is to rescue and salvage, usually have a hysterectomy with delivery of compromised neonate

Often neonate is dropped into the abdominal cavity from back of ruptured uterus

56
Q

What is the most common fetal malposition? What side do you want to avoid turning the patient onto?

A

LOP or ROP most common malposition:
Maternal risk includes prolonged labor, and potential for C-section if failure to rotate

AVOID turning patient to side the fetus’s back is facing
example, ROP- DO NOT turn on right side

57
Q

What is the greatest risk of vaginal delivery of a breech infant?

A

umbilical cord prolapse

58
Q

What causes problems with the passageway resulting in fetal hypoxia and birth trauma?

A
  • Abnormal size or shape of the pelvis
  • Have CPD (cephalopelvic disproportion) fetal head too large to pass through
  • Fetal macrosomia

Shoulder dystocia results from inability to deliver shoulders

59
Q

What medications help ripen the cervix (help initiate contractions)?

A

prostaglandin (PGE2 gel)

laminaria

60
Q

What drugs are used in the induction of labor?

A
  • prostaglandins: Cervidil or Prepidil intravaginally
  • misoprostol (Cytotec) orally or intravaginally
  • oxytocin (Pitocin) titrated to produce contractions that mimic normal labor
61
Q

Describe when Pitocin infusion should be stopped and what it is given in.

A

Should be stopped if:

  • Contractions are closer than 2 minutes apart or last longer than 90 seconds
  • Signs of fetal distress showing late decelerations or severe variable decels or bradycardia

Pitocin given in electrolyte FREE solution

62
Q

What is Hypotonic Uterine Dysfunction? Risks? Treatment?

A

-Infrequent contractions with decreased intensity

Risks are related to non progression of labor which usually comes with prolonged rupture of membranes and frequent vaginal exams leading to infection.

Treatment: Augmentation with Pitocin as long as CPD (Cephalopelvic Disproportion) is ruled out

63
Q

Describe Precipitous (dangerous) labor or rapid transit. What are the maternal risks and fetal risks?

A
  • Labor under 3 hrs from start to finish
  • Maternal risks: hemorrhage and lacerations

-Fetal risks result in: hypoxia, intracranial hemorrhage, and injury at birth
Baby will display reddened sclera, high pitched crying, inconsolability)

64
Q

Why would sedation be order for hypertonic contractions?

A

Sedation helps to provide rest and allows for the uterine contractions to become coordinated so that labor is progressive.

65
Q

What are some side effects of oxytocic meds?

A

edema in legs and feet

increased BP

decreased urine output
