Answer to Question 1

According to 2010 United States census data, the number of older adults, aged 65 and over, increased by 15.3 from 2000 to a total of 40.4 million (13.1 of the total United States population); it is estimated that number will increase to about 55 million by 2020 (Administration on Aging, 2011). The fastest growing group among older adults since the 1990 census are those over 100 years of age, increasing by 53 to a total of 53,364 in 2010 (National Center for Health Statistics, 2013). Most of these centenarians are considered to be among the most vulnerable to frailty and disability, which, coupled with the likelihood that they will live alone and, therefore, require support services, such as nursing home care, has caused dire predictions about the failure of the Medicare and Medicaid systems.
Answer to Question 2
ANS: D
A fetus may be found to be of a size that is not commensurate with normal growth rates (size not equal to dates) when the uterine size is measured and evaluated during routine prenatal visits. First-trimester uterine sizes are usually determined with bimanual examination, and sizedate discrepancies are often not clinically relevant. After 20 weeks of gestation, fundal height measurements begin to correlate (within 2 cm) with gestational age. False small-for-dates presentations may result from inaccurate LMP dates, varying menstrual cycle lengths, improper fundal height measurement, or a fetus in a transverse lie. False large-for-dates presentations may likewise be produced by inaccurate LMP dates, improper fundal height measurement, and a large amount of amniotic fluid as well as maternal obesity or short stature.
