A client with long-standing type 2 diabetes is surprised at his high blood sugar readings while recovering from an emergency surgery. Which of the following factors may have contributed to the client's inordinately elevated blood glucose levels?
A) The tissue trauma of surgery resulted in gluconeogenesis.
B) Illness inhibited the release and uptake of glucagon.
C) The stress of the event caused the release of cortisol.
D) Sleep disruption in the hospital precipitated the dawn effect.
Ans: C
Feedback:
Elevation of glucocorticoid levels, such as during stressful events, can lead to hyperglycemia. Tissue trauma does not cause gluconeogenesis, and illness does not inhibit the action of glucagon. The dawn phenomenon is not a likely cause of the client's disruption in blood sugar levels.
