Answer to Question 1

Ans:
B

Feedback:

Infections are more prevalent among older adults than younger adults, a situation that results partly from compromised immune function but mostly from the interplay between environmental factors and age-related changes. Illness is not entirely attributable to decreased immune function, and older adults do not necessarily produce fewer antibodies.

Answer to Question 2

Ans:
A

Feedback:

What is termed a normal value for a laboratory test is established statistically from results obtained from a selected sample of people. A normal value represents the test results that fall within the bell curve or the 95 distribution. Some lab values (like hemoglobin) are adjusted for gender, other comorbidities, or age. If the result of a very sensitive test is negative, it tells us the person does not have the disease, and the disease has been ruled out or excluded.
