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

Answer and Explanation

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.

Correct Answer is A

Explanation

Magnesium sulfate is a tocolytic drug that inhibits uterine activity and relaxes smooth muscles.The goal of magnesium sulfate therapy for a client who is in pre-term labor is to stop or reduce the frequency and intensity of contractions.

Choice B is wrong because the client’s blood pressure decreases to within normal limits.

Magnesium sulfate is not an antihypertensive drug and does not lower blood pressure.It is used to prevent seizures in clients with preeclampsia or eclampsia.

Choice C is wrong because the client’s deep tendon reflexes are 2+.

This is a normal finding and does not indicate the effectiveness of magnesium sulfate therapy.A decrease or loss of deep tendon reflexes may indicate magnesium toxicity, which is a serious complication that requires immediate intervention.

Choice D is wrong because the client’s urine output increases to more than 30 mL/hr.

This is also a normal finding and does not indicate the effectiveness of magnesium sulfate therapy.A decrease in urine output may indicate renal impairment or magnesium toxicity, which are both adverse effects of the drug.

The normal range for serum magnesium level is 1.5 to 2.5 mEq/L or 1.8 to 3 mg/dL.The therapeutic range for magnesium sulfate management is 5 to 8 mg/dL.

A. Ultrasound B. Blood count C. Urine culture D. Amniocentesis

Correct Answer is A

Explanation

Ultrasound.

An ultrasound can help determine the gestational age, fetal growth, placental location, and amniotic fluid volume of the fetus.

These factors can affect the risk of pre-term labor and delivery.

An ultrasound can also detect cervical changes that may indicate pre-term labor.

Choice B is wrong because a blood count is not specific for pre-term labor.

It may be done to check for anemia, infection, or other conditions that may affect the pregnancy, but it does not directly assess the risk of pre-term labor.

Choice C is wrong because a urine culture is not specific for pre-term labor.

It may be done to check for urinary tract infection, which can cause pre-term labor, but it does not directly assess the risk of pre-term labor.

Choice D is wrong because an amniocentesis is not usually done for pre-term labor.

It may be done to check for fetal lung maturity, chromosomal abnormalities, or infections, but it is an invasive procedure that carries some risks and complications.

It does not directly assess the risk of pre-term labor.
