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 B

Explanation

Choice A rationale

Using a disposable razor for shaving while taking warfarin can increase the risk of cuts and bleeding, which should be avoided due to the anticoagulant effects of warfarin.

Choice B rationale

Oral contraceptives should not be taken while on warfarin because they can increase the risk of blood clots, counteracting the effect of the anticoagulant.

Choice C rationale

Stopping warfarin in 2 weeks is incorrect advice, as the duration of therapy varies depending on the condition being treated and the individual's response to the medication.

Choice D rationale

Taking 650 milligrams of aspirin for leg discomfort is not advised while on warfarin, as aspirin can increase the risk of bleeding by affecting platelet function and the blood clotting process.

Correct Answer is C

Explanation

Choice A rationale

The newborn's legs flexing at the knees and hips when pressure is applied to the soles indicates the stepping reflex, an expected response.

Choice B rationale

Newborns do not typically keep their eyes closed when tapped on the forehead; this is not an expected reflex response.

Choice C rationale

The palmar grasp reflex, where the newborn's fingers curl around the nurse's finger, is an expected and normal finding in newborns, indicating healthy neurological function.

Choice D rationale

The rooting reflex, where the newborn turns their head when their cheek is touched, is expected and demonstrates feeding readiness and normal neural development. .
