Question

Quizplus · Accepted Answer

Signs and symptoms of hyperglycemia are thirst, headache, lethargy, and increased urination. Hypocapnia is not associated with parenteral nutrition. Hypercapnia increases oxygen consumption and increases CO₂ levels. Ventilator-dependent patients are at greatest risk for this. Hypoglycemia is characterized by diaphoresis, shakiness, confusion, and loss of consciousness.
