A woman at 26 weeks of gestation is being assessed to determine whether she is experiencing preterm labor. Which finding indicat

My name is Ann [436]

Answer:

A. The cervix is effacing and dilated to 2 cm.

Explanation:

PRETERM LABOUR:

DEFINITION:

Preterm labor is defined as labor or delivery that occurs before 37 weeks of gestation.

DIAGNOSIS

A pregnant patient is said to be undergoing preterm labor if:

Regular Uterine contractions ( at least 1 in 10 minutes).
Dilation of cervix up to 2 cm or greater and effacement of cervix up to 80%
Patient experiences pelvic pressure, backache, vaginal discharge or bleeding
Cervix is shortened up to less than 2.5 cm with funneling of internal os when examined by Transvaginal Ultrasound

Fetal Fibronectin is a glycoprotein that if found in vaginal secretion between 24 and 34 weeks of gestation is an excellent predictor of preterm labor and indicates that the patient is at high risk of undergoing of preterm labor.

Similarly, increased levels of maternal salivary estriol is a predictor of preterm labor.

Coming back to the answer choices,

A. The cervix is effacing and dilated to 2 cm.

This is the correct answer choice as effacement of cervix and dilation of cervix upto 2cm or greater is a diagnostic feature of preterm labor.

B. Irregular, mild uterine contractions are occurring every 12 to 15 minutes.

Regular uterine contractions at least 1 in 10 minutes is diagnostic of preterm labor. Therefore this is the incorrect answer choice. However, Uterine contractions equal to or greater than 4 per hour is a good predictor that patient will undergo preterm labor.

C. Fetal fibronectin is present in vaginal secretions.

Presence of fetal fibronectin in vaginal secretions is an excellent predictor of preterm labor. Therefore, this answer choice is inappropriate.

D. Estriol is not found in maternal saliva.

Elevated maternal salivary estriol is a predictor of preterm delivery. Therefore, this answer choice is also incorrect.

Roman55 [17]

If we could magically look down on our solar system, we would see that the half of the Moon facing the Sun is always lit. But the lit side does not always face the Earth! As the Moon circles the Earth, the amount of the lit side we see changes.
