A nurse is caring for a client with PROM who is receiving magnesium sulfate as a tocolytic agent.

Which of the following assessments should the nurse perform to monitor for magnesium toxicity?

Deep tendon reflexes

Urine output

Serum magnesium level

All of the above.

Answer and Explanation

The Correct Answer is D

The nurse should perform all of the assessments listed to monitor for magnesium toxicity.

Magnesium sulfate is a drug that is given to prevent preterm labor by relaxing the uterine muscle.

However, it can also cause serious side effects such as weakness, low blood pressure, respiratory paralysis, and cardiac problems if the level of magnesium in the blood is too high.

The normal level of magnesium in the blood is about 1.5-2.5 mEq/L. Symptoms of toxicity may appear when the level reaches 4 mEq/L or higher.

Correct Answer is D

Explanation

This value indicates a mature lecithin/sphingomyelin (L/S) ratio in the amniotic fluid, which reflects the fetal lung maturity and the low risk of respiratory distress syndrome (RDS) after birth.The L/S ratio is a test that measures the amount of lecithin and sphingomyelin, two types of phospholipids that are important for the formation of surfactant, a substance that prevents the lungs from collapsing.Lecithin increases and sphingomyelin stays constant as the fetus matures, so a higher L/S ratio indicates more surfactant and more lung development.A ratio of greater than 2:1 or 2.5:1 is 98% predictive of fetal lung maturity in most assays.

A. Discontinue oxytocin infusion and administer terbutaline B. Discontinue antibiotics and administer corticosteroids C. Discontinue tocolytics and prepare for delivery D. Discontinue corticosteroids and administer magnesium sulfate

Correct Answer is C

Explanation

chorioamnionitis is a serious infection of the placental tissues that can cause fetal and maternal morbidity and mortality.The best management is to deliver the baby as soon as possible to prevent further complications.

Normal ranges for maternal blood C-reactive protein (CRP), procalcitonin and interleukin 6 (IL6) are:

• CRP: <10 mg/L

• Procalcitonin: <0.5 ng/mL

• IL6: <5 pg/mL

These markers may be elevated in chorioamnionitis, but they have low sensitivity and specificity for diagnosis.
