A nurse is preparing to administer betamethasone (Celestone) to a client who is at 31 weeks of gestation and has pre-term labor.
What is the purpose of this medication?
To suppress uterine contractions
To prevent infection
To promote fetal lung maturity
To reduce maternal blood pressure
The Correct Answer is C
To promote fetal lung maturity. Betamethasone (Celestone) is a type of corticosteroid that can help reduce the risk of respiratory distress syndrome and other complications in preterm infants by accelerating the development of their lungs. It is recommended for pregnant women between 24 0/7 weeks and 36 6/7 weeks of gestation who are at risk of preterm delivery within 7 days.
Choice A is wrong because betamethasone does not suppress uterine contractions.
It has no effect on the cause of preterm labor.
Choice B is wrong because betamethasone does not prevent infection.
It may actually increase the risk of infection by suppressing the immune system.
Choice D is wrong because betamethasone does not reduce maternal blood pressure.
It may actually cause hypertension and hyperglycemia as side effects.

Explanation
A cervical cerclage is a procedure that involves placing stitches around the cervix to prevent it from opening prematurely.This procedure is usually done for women who have a history of cervical insufficiency or a short cervix, which are risk factors for preterm labor.
Choice A is wrong because history of gestational diabetes is not a risk factor for preterm labor.
Gestational diabetes is a condition that causes high blood sugar during pregnancy and can affect the health of the mother and the baby, but it does not increase the risk of preterm labor.
Choice C is wrong because history of recurrent urinary tract infections (UTIs) is a risk factor for preterm labor.
UTIs are infections that affect the urinary system and can cause symptoms such as pain, burning, or frequent urination.
UTIs can also spread to the kidneys or the uterus and cause inflammation or infection that can trigger preterm labor.
Choice D is wrong because history of assisted reproductive technology (ART) is a risk factor for preterm labor.
ART refers to any medical procedure that helps with conception, such as in vitro fertilization (IVF).
ART can increase the risk of preterm labor because it can result in multiple gestations (twins, triplets, or more), which put more strain on the uterus and can cause it to contract prematurely.ART can also cause complications such as placenta previa or rupture of the uterus, which can lead to preterm labor.
