A nurse is evaluating the effectiveness of antibiotic therapy for a client who has PPROM at 28 weeks of gestation.
Which of the following findings indicates a positive outcome?
Decreased fetal movements
Increased amniotic fluid index
Decreased maternal pulse rate
Increased maternal leukocyte count
The Correct Answer is B
Increased amniotic fluid index indicates a positive outcome of antibiotic therapy for a client who has PPROM at 28 weeks of gestation. Antibiotics are used to prevent or treat infection and prolong pregnancy in women with PPROM. Infection can cause oligohydramnios (low amniotic fluid) which can lead to fetal complications such as cord compression, pulmonary hypoplasia and limb deformities.
Therefore, an increased amniotic fluid index suggests that the infection has been reduced or resolved and the risk of preterm birth has been lowered.
Normal ranges for amniotic fluid index are 5 to 25 cm. Normal ranges for maternal pulse rate are 60 to 100 beats per minute. Normal ranges for maternal leukocyte count are 4.5 to 11 x 10^9/L.

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.
Correct Answer is D
Explanation
This is because PPROM increases the risk of infection for both the mother and the baby, and infection can cause fetal tachycardia, maternal leukocytosis, and increased vaginal discharge.
Normal ranges for fetal heart rate are 110 to 160 beats per minute.
Normal ranges for maternal white blood cells are 4,500 to 11,000/mm3.
Normal ranges for vaginal discharge vary depending on the stage of pregnancy and other factors.
