The nurse suspects that a healthy client could be experiencing stress because of which laboratory result?
A) Serum sodium of 142 mEq/L
B) Serum glucose of 165 mg/dL
C) Serum potassium of 4.0 mEq/L
D) Serum calcium of 10.2 mEq/L
Answer: B
Laboratory tests are not routinely done to evaluate anxiety because observation is faster and more accurate. However, they may be necessary to rule out medical conditions that can cause anxiety. The elevated blood glucose level could indicate that the client is experiencing stress because of an increase in adrenal function. One physiological indicator of stress is an increase in blood glucose because of the release of glucocorticoids and gluconeogenesis. The other laboratory values are within normal limits.
