A 17-year-old female has announced to her family physician a desire to wholly eliminate fats from her diet. Which of the following aspects of the role of fats would underlie the physician's response to the client?
 
  A)
  Apart from providing energy, fats are necessary as carriers of certain vitamins and are precursors to prostaglandins.
  B)
  An extreme low-fat diet is associated with an increase in undesirable HDL cholesterol.
  C)
  Fats are a key source of dietary nitrogen, and their elimination from the diet is associated with a negative nitrogen balance.
  D)
  The total elimination of fat from the diet is associated with the development of ketosis.

Question 2

Which of the following best describes the half-life of a highly protein-bound drug such as thyroxine (99 protein bound)? The half-life would be
 
  A)
  much longer to reduce the concentration of the hormone by one half.
  B)
  shorter because only a little of the hormone has to be used up to reduce the concentration.
  C)
  dependent on which drugs were in the blood system holding on to the hormone.
  D)
  dependent on the liver to carry the hormone to its designated target organ.

Answer to Question 1

Ans:
A

Feedback:

Far from being a completely undesirable component of the diet, dietary fats provide energy, function as carriers for the fat-soluble vitamins, serve as precursors of prostaglandins, and are a source of fatty acids. Low-fat diets tend to lower levels of HDL, which is a desirable form of cholesterol. Nitrogen balance is associated with protein, not fat, intake, and ketosis results from low-carbohydrate intake.

Answer to Question 2

Ans:
A

Feedback:

The half-life of a hormonethe time it takes for the body to reduce the concentration of the hormone by one halfis positively correlated with its percentage of protein binding. Thyroxine, which is more than 99 protein bound, has a half-life of 6 days, whereas aldosterone, 15 bound, has a half-life of only 25 minutes.
