Ch. 7 Placental abnormalities placenta previa and placental abruption

Ch. 7 Placental abnormalities placenta previa and placental abruption Leave the first rating Terms in this set (18) Save A nurse suspects possible placenta abnormalities for her G:1 P:1 client.What diagnostic test should the nurse recommend better help diagnose her client?

• Transabdominal ultrasound
• sterile vaginal exam
• fundal height measurement
• Doppler ultrasound
• transabdominal ultrasound

rationale: ultrasound confirms placental location at

the cervix and transvaginal ultrasonography also improves the accuracy of the diagnosis in the third trimester

• sterile vaginal examination should be avoided

because it can exacerbate bleeding

• Patients with placenta previa will have a fundal

height measurement that is greater than usual for their expected gestational age. not a diagnostic though.

• A doppler ultrasound is useful for assessing

IUGR What is placenta previa?placenta implants in the lower segment of the uterus NEAR or OVER the cervical os instead of attaching to the fundus. This causes abnormal bleeding during the third trimester as the cervix begins to dilate and efface.

The cervical os is completely covered by the placental attachment

• low-lying
• marginal
• incomplete or partial
• complete
• complete

The cervical os is only partically covered by the placental attachment

• low-lying
• marginal
• incomplete or partial
• complete
• incomplete or partial

The placenta is attached in the lower uterine segment but does not reach the cervical os.

• low-lying
• marginal
• incomplete or partial
• complete

marginal The exact relationship of the placenta to the internal os has not been determined

• low-lying
• marginal
• incomplete or partial
• complete

low-lying

The newly licensed nurse asks her preceptor, "How is placenta previa classified? What is the best response by the nurse?

• Placenta previa is classified

through a vaginal exam if it is complete, incomplete, marginal, or low-lying

• Placenta previa is classified

depending on the amount of vaginal bleeding during the second or third trimester

• Placenta previa is classified based

on whether it is painful or painless

• Placenta previa is classified

depending on the degree to which the cervical os is covered by the placenta

• Placenta previa is classified depending on the

degree to which the cervical os is covered by the placenta

rationale: classified into three types of dependent

on the degree to which the cervical os is covered by the placenta.

• vaginal exam is CI for placenta previa, and an

ultrasound would be used to determine complete, incomplete, marginal, or low-lying

• vaginal bleeding is an expected finding
• painless is an expected finding

If the placenta is covering the cervical os to any degree. What is it called?previa If the placenta is not covering the cervical os, but it is near it. What is it called?low-lying placenta What are risk factors for placenta previa? (SATA)

• long pregnancy interval
• abortion with suction curettage

C. HTN

• prior cesarean birth
• abortion with suction curettage
• prior cesarean birth

What are risk factors for placenta previa? (SATA)

• maternal age of <25>
• diabetes
• hypotension
• smoking
• diabetes
• smoking
• advanced maternal age of >35
• hypertension

also endometritis and fibroids what is exsanguination?Exsanguination is death caused by loss of blood The nurse is teaching about risks for women who have placenta previa.Which of the following indicates a need for further teaching?

• maternal exsanguination in 5

minutes

• hemorrhagic and hypovolemic

shock

• Develop Rh sensitization for Rh-

negative moms

• thrombophlebitis

maternal exsanguination in 5 mintues

rationale: this happens in 10 minutes and means that

the mother can die within 10 minutes from the loss of blood.
