A nurse is assisting with the care of a 30-year-old female client who is scheduled to receive a dose of dinoprostone in the maternal newborn unit.

 

Exhibit 1: Vital Signs

 

  • Heart rate: 88/min
  • Temperature: 37.1°C (98.8°F)
  • Respiratory rate: 16/min
  • Blood pressure: 122/78 mm Hg

 

Exhibit 2: Provider Prescriptions

 

  • Levothyroxine 100 mcg PO once daily in PM
  • Acetaminophen 325 mg PO every 6 hr PRN
  • Dinoprostone 10 mg intravaginally x one dose now
  • Terbutaline 2.5 mcg/min intravenous per provider's instructions

 

Exhibit 3: Laboratory Results

 

  • WBC count: 9,500/mm³ (Normal: 5,000 to 15,000/mm³)
  • Hgb: 10.5 mg/dL (Normal: greater than 11 mg/dL)
  • Hct: 31% (Normal: greater than 33%)
  • Platelets: 225,000/mm³ (Normal: 150,000 to 400,000/mm³)
  • Blood Type/Rh: O+

 

Exhibit 4: Assessment

 

The fetal heart rate is 140/min with moderate variability, and mild uterine irritability is noted. The abdomen is soft and nontender upon palpation. Cervical examination reveals dilation of 1 cm, thickness, and no presenting part palpable. An ultrasound shows a footling breech presentation. There are clusters of lesions noted on the vaginal introitus and labia majora.

 

Exhibit 5: History and Physical

 

The client is gravida 2 para 1, with a previous vaginal delivery. She has a history of hypothyroidism and Herpes simplex virus type 2. She is currently undergoing labor induction at 39 weeks and 3 days of gestation.

 

Querry

For which of the following findings should the nurse anticipate a provider's prescription to withhold the dinoprostone? Select all that apply.

A.

Breech presentation

B.

Terbutaline administration

C.

FHR (Fetal Heart Rate)

D.

WBC count

E.

Lesions noted

Question Solution

Correct Answer : A,C,E

Choice A rationale:

 

Breech presentation is a contraindication for dinoprostone as it increases the risk of complications during labor and delivery. Using dinoprostone to induce labor in a non-vertex presentation can lead to issues such as cord prolapse or obstructed labor, which necessitate a cesarean section for safe delivery.

 

Choice B rationale:

 

Terbutaline administration is used to manage preterm labor by relaxing the uterus. While it is relevant in labor management, it does not directly contraindicate the use of dinoprostone. Terbutaline and dinoprostone can be used in conjunction if properly managed.

 

Choice C rationale:

 

Fetal heart rate (FHR) monitoring showing abnormalities is a potential reason to withhold dinoprostone. Dinoprostone can increase uterine contractions, potentially stressing the fetus. A stable FHR with moderate variability indicates fetal well-being; however, if there were concerns, the provider might withhold dinoprostone.

 

Choice D rationale:

 

A WBC count of 9,500/mm³ is within the normal range and does not indicate an infection or condition that would contraindicate dinoprostone use. Elevated WBC count could raise concerns, but in this case, it is normal and not a contraindication.

 

Choice E rationale:

 

Lesions noted on the vaginal introitus and labia majora, likely caused by Herpes simplex virus, are a contraindication for dinoprostone. Active genital herpes lesions increase the risk of neonatal herpes transmission, making vaginal delivery risky. In such cases, cesarean delivery is often preferred to prevent transmission.

Correct Answer is A

Explanation

Choice A rationale

"You will be tested again for GBS at about 36 weeks of gestation.”. This is correct because retesting for GBS at 35-37 weeks of gestation is standard practice to identify colonization status before delivery, which helps in planning intrapartum antibiotic prophylaxis.

Choice B rationale

"If you test positive for GBS, the provider will need to perform a cesarean birth.”. This is incorrect because GBS colonization is not an indication for cesarean delivery. The primary intervention is antibiotic administration during labor to prevent neonatal infection.

Choice C rationale

"You will take an antibiotic during the last 2 weeks of pregnancy to avoid transferring GBS to your baby.”. This is incorrect because antibiotics are given intrapartum (during labor) to prevent GBS transmission, not during the last weeks of pregnancy.

Choice D rationale

"This infection can cause your baby to experience hearing loss at birth.”. This is incorrect because GBS infection primarily causes sepsis, pneumonia, and meningitis in neonates, not hearing loss.

Correct Answer is B

Explanation

Choice A rationale

Increasing the frequency of feedings from the affected nipple may aggravate nipple soreness, as it doesn't allow the area to recover and heal properly between feedings.

Choice B rationale

Exposing the affected nipple to the air between feedings can help it to dry and heal, reducing soreness. Air exposure can help prevent bacterial growth and keep the nipple area healthy.

Choice C rationale

Applying vitamin E oil to the affected nipple before each feeding is not recommended as it can make the nipple slippery, affecting the baby's latch, and it might not be safe if ingested by the baby.

Choice D rationale

Washing the affected nipple with soap and water before each feeding can strip the natural oils from the skin, leading to further dryness and irritation, which can increase soreness.
