A nurse is reviewing the laboratory results of a client who has PPROM at 30 weeks of gestation.

The nurse should expect to see which of the following values for the lecithin/sphingomyelin (L/S) ratio in the amniotic fluid?

0.5

1.0

1.5

2.0

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is D

Explanation

Corticosteroids have multiple effects on the fetus, including:

• Decreasing the risk of respiratory distress syndrome (RDS) by increasing the production of surfactant, a substance that helps the lungs expand and prevents them from collapsing.

• Reducing the incidence of intraventricular hemorrhage (IVH), a type of bleeding in the brain that can cause brain damage or death.

• Reducing the risk of necrotizing enterocolitis (NEC), a serious intestinal infection that can cause tissue death and perforation.

Normal ranges for gestational age are 37 to 42 weeks.

Normal ranges for fetal weight are 2.5 to 4.5 kg.

Normal ranges for fetal heart rate are 110 to 160 beats per minute.

Normal ranges for amniotic fluid index are 5 to 25 cm.

A. Placental abruption B. Chorioamnionitis C. Prolapsed cord D. Fetal distress

Correct Answer is B

Explanation

Chorioamnionitis is an infection of the membranes containing the fetus and the amniotic fluid.It can occur when the membranes rupture before labor, especially if the rupture is prolonged or preterm.Chorioamnionitis can cause fever, foul-smelling vaginal discharge, abdominal pain, and fetal tachycardia.

Normal ranges for temperature are 36.5°C to 37.5°C (97.7°F to 99.5°F) and for fetal heart rate are 110 to 160 beats per minute.
