Answer to Question 1

A
In the age-stratification model, historical context is used to understand members of a cohort in terms of similar events, conditions, and circumstances and the effect these have on the group as a whole. A good example of such a cohort is older adults who lived through World War II. Bio-logical context is not important in considering the age-stratification theory. The age-stratification theory is a sociological theory of aging that uses historical context to describe cohorts. Chrono-logical context of a cohort will span a range, but historical context is what describes the cohort.

Answer to Question 2

D

Feedback
A Incorrect. TB is not as contagious as formerly supposed, but drug-resistant forms exist and are a serious risk for elders who are immunocompromised.
B Incorrect. A PPD test has a false-negative rate of approximately 30. When the result is positive, the patient receives a sputum culture and chest x-ray exam. A positive sputum culture is necessary to confirm the diagnosis.
C Incorrect. Although medications such as isoniazid (INH) were thought to have eliminated TB, the organism is present in multidrug-resistant forms.
D Correct. Elders who contracted TB before the 1940s may suffer reactivation of the bacterium. Most reported cases of TB among elders are from nursing homes.
