A nurse is teaching a class about the general adaptive syndrome. The nurse should include that which of the following manifestations occurs during the exhaustion stage?
Blood glucose levels return to the expected reference range.
Blood pressure increases.
Depression
Dilation of pupils
The Correct Answer is C
A. Blood glucose levels return to the expected reference range. Blood glucose levels are more likely to be elevated due to prolonged stress during the exhaustion stage, not normalized.
B. Blood pressure increases. During the exhaustion stage, the body's resources are depleted, and blood pressure may drop rather than increase.
C. Depression: The exhaustion stage is characterized by physical and psychological symptoms such as depression, fatigue, and reduced immune function.
D. Dilation of pupils: Pupil dilation occurs during the alarm stage of the general adaptation syndrome, not during the exhaustion stage.

Correct Answer is B
Explanation
A. Moist skin: Dehydration typically causes dry skin due to reduced fluid volume, not moist skin. This finding is not expected in a dehydrated client.
B. Dark-colored urine: Dark-colored urine is a common sign of dehydration, as the urine becomes more concentrated when the body conserves water. This finding is expected.
C. Distended neck veins: Dehydration typically causes flat or collapsed neck veins due to decreased blood volume. Distended neck veins are more associated with fluid overload or heart failure. This finding is not expected.
D. High blood pressure: Dehydration often leads to low blood pressure due to reduced blood volume. High blood pressure is not typically associated with dehydration.
Correct Answer is C
Explanation
A. Lactulose: Lactulose is used to reduce blood ammonia levels in hepatic encephalopathy, not to reduce potassium levels. It is not appropriate for treating hyperkalemia.
B. Sevelamer: Sevelamer is a phosphate binder used in clients with chronic kidney disease to lower serum phosphorus levels, not potassium. It is not appropriate for treating hyperkalemia.
C. Sodium polystyrene: Sodium polystyrene (Kayexalate) is a cation-exchange resin used to treat hyperkalemia. It works by exchanging sodium ions for potassium ions in the intestine, promoting the excretion of potassium. This is the correct medication to administer for a serum potassium level of 6.8 mEq/L.
D. Darbepoetin alfa: Darbepoetin alfa is a synthetic erythropoietin used to treat anemia associated with chronic kidney disease. It is not used to treat hyperkalemia.
