During stress, giving patients extra insulin does not always decrease their high blood glucose levels because
 
  a. the ratio of glucagon to insulin is in-creased.
  b. the extra insulin stimulates glucose pro-duction.
  c. the number of insulin receptors on cells decreases.
  d. high blood glucose levels help protect the body against infection.

Question 2

Burn injuries can result in excessive loss of:
 
  1. Fluids.
   2. Proteins.
   3. Vitamin A.
   4. Fats.

Answer to Question 1

A
Giving patients extra insulin does not always decrease high blood glucose levels in stressed pa-tients because the ratio of glucagon to insulin is increased. Insulin stimulates uptake of glucose by cells; it does not stimulate glucose production. Stress does not change the number of insulin receptors on cells. High blood glucose levels tend to increase risk of infection rather than pro-tecting the body against infection.

Answer to Question 2

1
Rationale: Excessive burn injuries can result in an excessive loss of fluids, resulting in fluid and electrolyte imbalances. Increased proteins may be needed to synthesis tissue for wound healing and repair. Vitamin A is also need for wound healing, but is not lost as a result of burn injuries. Fats are not affected with burn injuries unless adequate calories are not available to meet the body's requirements for energy and tissue synthesis, in which fat stores would be mobilized to be used as energy.
