A nurse is administering betamethasone to a client who is at risk for pre-term labor at 30 weeks of gestation.

Which of the following outcomes should the nurse monitor for in the newborn?

Increased surfactant production

Decreased risk of infection

Increased blood glucose levels

Decreased risk of bleeding

Answer and Explanation

The Correct Answer is A

Betamethasone is a corticosteroid that is given to pregnant women who are at risk of preterm labor to improve neonatal outcomes. Betamethasone stimulates the production of surfactant, a substance that lubricates the lungs and prevents them from collapsing after birth. This reduces the risk of respiratory distress syndrome, a common complication of preterm birth.

Choice B is wrong because betamethasone does not decrease the risk of infection in the newborn. In fact, it may increase the risk of maternal and neonatal infections by suppressing the immune system.

Choice C is wrong because betamethasone does not increase blood glucose levels in the newborn. However, it may cause transient hyperglycemia in the mother, which should be monitored and treated if necessary.

Choice D is wrong because betamethasone does not decrease the risk of bleeding in the newborn. It may increase the risk of intraventricular hemorrhage, a type of bleeding in the brain, if given before 24 weeks of gestation. Therefore, it should be used with caution in this population and only after a family’s decision regarding resuscitation.

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.

A. Hypertension B. Hyperreflexia C. Respiratory depression D. Tachycardia

Correct Answer is C

Explanation

Magnesium sulfate is a drug that is used to prevent seizures associated with pre-eclampsia and to stop preterm labor.However, it can also cause adverse effects such as respiratory depression, which is a condition where the breathing rate becomes too slow and shallow.

Respiratory depression can be life-threatening for both the mother and the baby, so the nurse should monitor the client’s respiratory rate and oxygen saturation closely.

Choice A is wrong because magnesium sulfate can cause hypotension, not hypertension.Hypotension is low blood pressure, which can lead to dizziness, fainting, and shock.

Choice B is wrong because magnesium sulfate can cause hyporeflexia, not hyperreflexia.Hyporeflexia is a reduced or absent reflex response, which can indicate magnesium toxicity.

The nurse should check the client’s deep tendon reflexes regularly and stop the infusion if they are absent.

Choice D is wrong because magnesium sulfate can cause bradycardia, not tachycardia.

Bradycardia is a slow heart rate, which can reduce the blood flow to vital organs.
