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 C

Explanation

The therapeutic effect of magnesium sulfate is to inhibit uterine contractions and prevent or delay preterm labor.

By assessing uterine activity, the nurse can evaluate if the medication is working or not.

Choice A is wrong because measuring urine output is not directly related to the therapeutic effect of magnesium sulfate, but rather to monitor for toxicity and renal function.

Choice B is wrong because checking deep tendon reflexes is also not directly related to the therapeutic effect of magnesium sulfate, but rather to monitor for neuromuscular effects and toxicity.

Choice D is wrong because monitoring blood pressure is not directly related to the therapeutic effect of magnesium sulfate, but rather to monitor for cardiovascular effects and toxicity.

A. Administer tocolytic medication to stop contractions B. Instruct the client to empty her bladder C. Obtain informed consent from the client D. Monitor fetal heart rate and activity

Correct Answer is B

Explanation

Instruct the client to empty her bladder.This is because a full bladder can interfere with the insertion of the needle and increase the risk of injury to the bladder or the uterus.Emptying the bladder also reduces discomfort during the procedure.

Choice A is wrong because administering tocolytic medication to stop contractions is not necessary before amniocentesis.Tocolytic medication can have side effects and should only be used when there is a clear indication of preterm labor.

Choice C is wrong because obtaining informed consent from the client is not a nursing action, but a medical one.The nurse can assist in providing information and answering questions, but the final consent should be obtained by the doctor who will perform the procedure.

Choice D is wrong because monitoring fetal heart rate and activity is not a specific action before amniocentesis, but a routine part of prenatal care.Fetal heart rate and activity can be affected by many factors, such as maternal position, fetal sleep cycle, or maternal blood sugar level.

Monitoring them before amniocentesis does not provide any useful information for the procedure.
