Q

Diet and nursing interventions for Hyperemesis Gravidarum

A

Once the vomiting has stopped, feedings are started in small amounts at frequent intervals. In the beginning, limited amounts of oral fluids and bland foods such as crackers, toast, or baked chicken are offered.

  • Avoid an empty stomach. Eat frequently, at least every 2–3 h. Separate liquids from solids, and alternate every 2–3 h.
  • Eatahigh-protein snack at bedtime.
  • Eat dry, bland, low-fat, and high-protein foods. Cold foods may be better
    tolerated than those served at a warm temperature.
  • In general, eat what sounds good to you rather than trying to balance your
    meals.
  • Follow the salty and sweet approach;evenso-called junk foods are okay.
  • Eatproteinaftersweets.
  • Dairy products may stay down more easily than other foods.
    *If you vomit even when your stomach is empty,try sucking on a Popsicle.
  • Try ginger tea.Peel and finely dice a knuckle-sized piece of ginger and place it in a mug of boiling water. Steep for 5–8 min and add brown sugar to taste.
  • Try warm ginger ale (with sugar, not artificial sweetener) or water with a
    slice of lemon.
  • Drink liquids from a cup with a lid.

Q

What can be a risk factor for abortion

A

Approximately half of all miscarriages are chromosomally normal, while the other half have a chromosomal abnormality. Other possible causes of miscarriage include various medical disorders (e.g., poorly controlled diabetes mellitus, obesity, thyroid disease, and systemic lupus erythematosus). Regular and heavy alcohol consumption, excessive (.500 mg/day) caffeine intake, environmental toxins, and increasing pa- ternal age are other possible causes of miscarriage. Infections, however, are not a common cause of miscarriage

Q

Drug therapy after miscarriage

A

After evacuation of the uterus, oxytocin (Pitocin) is often given to prevent hemorrhage. For excessive bleeding after the miscarriage, ergot products such as ergonovine (Methergine) or a prostaglandin deriva- tive such as methylcarboprost tromethamine (Hemabate) may be given to contract the uterus

25
Q

Care after miscarriage

A
  • Clean the perineum after each voiding or bowel movement and change perineal pads often.
  • Shower(avoid tub baths) for 2weeks.
  • Avoid tampon use, douching, and vaginal intercourse for2 weeks.
  • Notify your health care provider if an elevated temperature or a foul-
    smelling vaginal discharge develops.
  • Eat foods high in iron and protein to promote tissue repair and red bloodcell
    replacement.
  • Seek assistance from support groups, clergy, or professional counseling as
    needed.
  • Allow yourself (and your partner) to grieve the loss before becoming preg-
    nant again.
26
Q

Where does 95% of Ectopic p-pregnancies occur

A

in fallopian tube, when discovered will result in immediate abortion due to health risk of mother and baby

27
Q

Signs and symptoms of Ectopic Pregnancy

A

Abdominal pain, referred shoulder
pain
* Delayed menses or abnormal
vaginal bleeding
* Weakness, dizziness, hypotension
(hypovolemia)

28
Q

Medical management and surgical management of Ectopic surgery

A

Medical: Methotrexate-Many women with an early diagnosis of ectopic pregnancy can be managed medically with methotrexate (ACOG, 2018b). Methotrexate is an antimetabolite and folic acid antagonist that destroys rapidly dividing cells, which ends the pregnancy.

The pregnancy is then ab- sorbed by the body over the next 4 to 6 weeks.

  • Surgical
  • Salpingectomy: remove all or part
    of tube
  • Salpingostomy: remove products
    of conception repair fallopian
    tube

Ectopic implanted
Abdominal cavity:
(rare) associated with
multiple anomalies of fetus
&significant damage to
maternal organs from
placental implantation if
fetus develops

29
Q

What is cervical Insufficiency, What procedure would be recommended to resolve it?

A

One cause of late miscarriage is cervical insufficiency, which has tra- ditionally been defined as passive and painless dilation of the cervix leading to recurrent preterm births during the second trimester in the absence of other causes\

Cervical cerclage placement has been the treatment of choice for women with cervical insufficiency due to cervical weakness.

30
Q

Is Methotrexate a hazardous drug and should HCP take caution when handling it?

A
  • Don two pairs of gloves before removing the syringe(s) from the sealed plastic bag.
  • Remove the syringe cap and replace with an appropriate needle for intra- muscular injection.

*Do not expel air from the syringe or prime the needle because these actions could aerosolize the methotrexate.

  • Check the patient’s identity and the medication and dosage before injecting the methotrexate. A second nurse should also perform an independent check before the injection is given.
  • Dispose of any items worn or used to prepare, dispense, or administer the methotrexate injection in a waste container designated specifically for hazardous drugs.
  • Wash hands thoroughly after removing gloves.
31
Q

What range of gestation is labeled as preterm labor

A
  • Diagnosis based on 3 factors:
  • 20-36 weeks gestation
  • Uterine activity (contractions)
  • Progressive cervical change
    (effacement and/or dilation)
  • Risk factors: history of PTL (#1 risk),
    multiple gestation, gestational
    diabetes, advanced maternal age,
    obesity, 2nd trimester bleeding,
    African-American race, low pre-
    pregnancy weight, urogenital tract
    infections
32
Q

S/S of preterm labor

A

Contractions every 10 minutes or less
for 1 hour or more (6 or more in an
hour)
* Lower abdominal menstrual-like cramps
* Dull, intermittent low back pain (below
waist)
* Suprapubic pain or pressure
* Pelvic pressure or heaviness (baby
“pushing down”)
* Character or amount change of cervical
discharge (leukorrhea)
* Rupture of amniotic membranes
* Signs of UTI

33
Q

Treatment of Preterm Labor

A

Lifestyle modifications: ↓ activity,
lifting, riding long distances
* Hydration
* Tocolytic medications relax smooth
muscle:
* Magnesium sulfate (↓ seizure risk)
* Terbutaline: oral or SC (pulse rate,
>120 hold)
* Indomethacin (Indocin)
* Nifedipine (Procardia)

34
Q

Is it common for a woman to experience a recurrent Ectopic Pregnancy

A. Yes
B. No

A

A. Yes

Every woman who has been diagnosed with an ectopic pregnancy should be instructed to contact her health care pro- vider as soon as she suspects that she might be pregnant because of the increased risk for recurrent ectopic pregnancy.

35
Q

How would you define the term multiple gestation

A
  • Pregnancy with multiple fetuses
    (twins, triplets…)
  • Increased risk for complications:
  • Increased blood volume required
    to support multiple fetuses
    (cardiovascular stress)
  • Over distention of uterus
    (preterm labor, PP hemorrhage)
  • Placement of placenta (previa or
    abruption)
  • Malpresentation (surgical
    delivery)
  • Nutrition

bleeding, scant pink to
bloody mucous plug

37
Q

What occurs during Placenta Previa?

A

Placenta cover cervical opening

There are 3 stages of Placenta Previa
Marginal-Placenta is implanted in lower uterus but its lower border is >3 cm from internal cervical os.

Partial-Lower border of placenta is within 3 cm of internal cervical os but does not fully cover it.

Total-Placenta completely covers internal cervical os.

38

    pain, and an increase in fundal height.
  3. Maintain bed rest; administer oxygen, IV uids,
    and blood products as prescribed.
  4. Place the client in Trendelenburg’s position if in- dicated to decrease the pressure of the fetus on the placenta, or place in the lateral position with the head of the bed at if hypovolemic shock oc- curs.
  5. Monitor and report any uterine activity.
  6. Prepare for delivery of the fetus as quickly as possible, with vaginal delivery preferable if the fetus is healthy and stable and the presenting part is in the pelvis; emergency cesarean delivery is performed if the fetus is alive but shows signs
    of distress.

Q

Can a UTI induce preterm labor?

A. No
B. Yes

A

B. Yes

Increased risk premature labor,
ascending infection

53
Q

What can UTI’s lead to if untreated>?

A

Asymptomatic bacteriuria refers to the persistent presence of bacteria within the urinary tract of women who have no symptoms. A clean- voided urine specimen containing more than 100,000 colonies per milliliter is diagnostic. If asymptomatic bacteriuria is not treated, about one-third of pregnant women will develop acute pyelonephritis. Therefore, all women should be screened for asymptomatic bacteriuria at their first prenatal visit (Duff, 2021). Asymptomatic bacteriuria has been associated with preterm birth and low birth weight infants (Cun- ningham et al., 2018).

Asymptomatic bacteriuria should be treated with an antibiotic. Antibiotics that are often prescribed include amoxicillin, ampicillin, a cephalosporin such as cephalexin (Keflex), ciprofloxacin (Cipro), levo- floxacin (Levaquin), nitrofurantoin (Macrodantin), and trimethoprim- sulfamethoxazole (Bactrim DS).
Cystitis - s/s dysuria, urinary frequency

Pyelonephritis- hospitalization needed

54
Q

Mechanisms of trauma

A

etal physiologic characteristics
* Fetal monitor tracing works as
“oximeter” of internal maternal
well-being
* Mechanisms of trauma
* Blunt abdominal trauma-Blunt abdominal trauma is most commonly the result of MVAs but also may be the result of intimate partner violence or falls. Maternal and fetal mortality and morbidity rates are directly correlated with whether the mother remains inside the vehicle or is ejected.
* Penetrating abdominal trauma-Bullet and stab wounds are the most frequent causes of penetrating abdominal trauma in pregnant women
* Thoracic trauma-
Thoracic trauma is reported to produce 25% of all trauma deaths. Pulmonary contusion results from nearly 75% of blunt thoracic trauma and is a potentially life-threatening condition.

55
Q

Care

A
  • Immediate stabilization
  • Primary survey
  • Cardiopulmonary resuscitation-The systematic evaluation begins with a primary survey and the initial CABDs of resuscitation: compressions, airway, breathing, and defibrilla- tion. Increased oxygen needs during gestation necessitate a rapid re- sponse.
  • Secondary survey-After immediate resuscitation and successful stabilization measures, a more detailed secondary survey of the mother and fetus should be completed. A complete physical assessment, including all body sys- tems, is performed.
  • Electronic fetal monitoring-
  • Fetal-maternal hemorrhage
  • Ultrasound
  • Radiation exposure
  • Perimortem cesarean delivery(only 5 minutes after mothers death)

External FHR and contraction monitoring is recommended after blunt trauma in a viable gestation for a minimum of 4 hours, regardless of injury severity. Fetal monitoring should be initiated soon after the woman is stable

55
Q

Does perineal pressure warrant immediate return to the hospital following a CERLAGE

A

Additional instruction includes the need to watch for and report signs of preterm labor, rup- ture of membranes, and infection. Finally, the woman should know the signs that would warrant an immediate return to the hospital, in-cluding strong contractions less than 5 minutes apart, preterm prela- bor rupture of membranes, severe perineal pressure, and an urge to push.

56
Q

Can dehydration cause contractions?

A

Dehydration can cause contractions make sure mom is well hydrated

57
Q

What is the cure for HELLP SYNDROME
