At 12 weeks' gestation, ultrasonography showed increased nuchal translucency and pregnancy-associated plasma protein A (PAPP-A) was decreased by 2 standard deviations. Chorionic villus sampling showed a 47, XX karyotype. During this visit, ultrasonography shows a hypoplastic nasal bone, shortened femur length, shortened middle phalanges of the fifth digits with clinodactyly. A quadruple marker test would most likely show which of the following sets of findings?
