Question 1 of 5
A 27-year-old primigravida at 32 weeks' gestation has been diagnosed with complete placenta previa. Conservative management including bed rest is the proper medical management. The goal for fetal survival is based on fetal lung maturity. The test used to determine fetal lung maturity is:
Correct Answer: D
Rationale: Dinitrophenylhydrazine is a laboratory test used to detect phenylketonuria, maple syrup urine disease, and Lowe's syndrome. Metachromatic stain is a laboratory test that may be used to diagnose Tay-Sachs and other lipid diseases of the central nervous system. The blood serum phenylalanine test is diagnostic of phenylketonuria and can be used for wide-scale screening. A lecithin-sphingomyelin ratio of at least 2:1 is indicative of fetal lung maturity, and survival of the fetus is likely.
