Answer to Question 1

ANS: A
Older adults have a higher ratio of adipose (fat) tissue where lipophilic (fat-soluble) medications can be stored thus resulting in a potential for an accumulation of the medication and potentially fatal overdoses. Older adults have a decrease in lean body mass and an increase in fat. An in-creased body mass would not affect lipophilic medication absorption. Older adults have a de-creased glomerular filtration rate, which begins to decline as early as age 25. Older adults have a decrease in overall kidney function.

Answer to Question 2

ANS: D, E
Abnormally low triglyceride levels are suggestive of malnutrition or hyperthyroidism. Reasons for elevated levels include chronic renal failure and poorly controlled diabetes. Severely elevated triglyceride levels (greater than 2000 mg/dL) are a strong risk factor for pancreatitis.
