Q

What is prophylactic cervical cerclage?

A

Surgical reinforcement of the cervix with a heavy ligature that is placed submucousally around the cervix to strengthen it and prevent premature cervical dilation

-Best results if done before 23-24 weeks gestation; cellarage is removed at 37 weeks or when labor begins

A
  • Abdominal pain
  • Flushed dry skin
  • Frequent urination
  • Fruity breath
  • Nausea
  • Thirst
31
Q

Describe the glucola screening test/1hr glucose tolerance test.

A

Client comes in and gets 50 g oral glucose load followed by plasma glucose analysis 1 hour later

  • Fasting not necessary
  • Preformed 24-28 weeks gestation
  • If glucose comes back 130-140 mg/dL or greater, then the 3 hour glucose test would be indicated
32
Q

Described the 3 hour glucose tolerance test.

A

Client comes in after fasting overnight. Fasting includes avoiding caffeine and not smoking for 12 hours prior to the test. A fasting glucose is obtained, then 100 g glucose load is given and the glucose levels are taken at 1, 2, and 3 hours following the glucose ingestion

33
Q

What is the underlying mechanism for the manifestations of pregnancy hypertensive disorders?

A

Vasospasm contributing to poor perfusion

34
Q

Gestational hypertension (GH), which begins after the ___ week of pregnancy, describes HTN disorders of pregnancy whereby the woman has an elevated BP at _____ or greater recorded at least twice, 4-6 hours apart, and within a 1 week period. There is no proteinuria. The presence of edema is no longer considered in the definition of HTN disease of pregnancy. The clients BP returns to baseline by 6 weeks postpartum

A

20th week; 140/90 or greater

35
Q

Mild preeclampsia is GH with the additions of proteinuria of greater than ____.

What else may be present with mild preeclampsia?

A

1+

Transient headaches may or may not occur along with episodes of irritability; edema may be present

A
  1. Inform client she may feel flushed, hot, and sedated with the bolus
  2. Monitor BP, PR, RR, reflexes, LOC, UO, headache/visual disturbances, epigastric pain, contractions, and FHR/activity

A
  • Absence of patellar deep tendon reflexes
  • UO less than 30 mL/hr
  • RR less than 12/min
  • Decreased LOC
  • Cardiac dysrhythmias
45
Q

What do we do if magnesium sulfate toxicity is suspected?

  • Immediately discontinue the infusion
  • Administer the antidote: CALCIUM GLUCONATE
