Answer to Question 1

A
The American Heart Association views a triglyceride level of < 100 mg/dL as desirable.

Answer to Question 2

B
Normal aging results in the progressive loss of elastic recoil of the lung parenchyma and con-ducting airways as well as reduced elastic recoil of the lung and the opposing forces of the chest wall. The lung becomes less elastic as collagenic substances surrounding the alveoli and alveolar ducts stiffen and form cross-linkages that interfere with the elastic properties of the lungs. Any and all of these structural changes make it more difficult for the older person to ventilate.
