(A) Autonomic dysreflexia is the exaggerated sympathetic nervous system response to various stimuli in the anesthetized area. Sympathetic stimulation results in severe, uncontrolled hypertension, which may result in myocardial infarction or cerebral hemorrhage. (B) Bradycardia occurs as a result of sympathetic blockade in the immediate postinjury period. After spinal shock recedes, cardiovascular stability returns, but the client will be bradycardiac for life. (C) Central cord syndrome is a specific type of spinal cord injury that occurs as a result of either hyperextension injuries or disrupted blood flow to the spinal cord. (D) Spinal shock occurs in the immediate postinjury phase and usually resolves in approximately 72 hours.

(A) The chloride level is within acceptable limits. (B) The sodium level is within acceptable limits. (C) This value indicates hypokalemia, rather than the hyperkalemia that occurs during diabetic ketoacidosis. (D) When diabetic ketoacidosis exists, intracellular dehydration occurs and potassium leaves the cells and enters the vascular system, thus increasing the serum level beyond an acceptable range. When insulin and fluids are administered, cell walls are repaired and potassium is transported back into the cells.
Normal serum potassium levels range from 3.5-5.0 mEq/L.

Explanation:
(A) Waterhouse-Friderichsen syndrome is peripheral circulatory collapse, which may result in extensive and diffuse intravascular coagulation and thrombocytopenia resulting in death. (B) Syndrome of inappropriate antidiuretic hormone is a complication of meningitis, but it is not Waterhouse-Friderichsen syndrome. (C) Cerebral edema resulting in hydrocephalus is a complication of meningitis, but it is not Waterhouse-Friderichsen syndrome. (D) Auditory nerve damage resulting in permanent hearing loss is a complication of meningitis, but it is not Waterhouse- Friderichsen syndrome.
