Lisette's NCLEX MED SURG Study

A 25-year-old physical fitness instructor is feeling increasingly tired and seeks medical care. Type 1 diabetes is diagnosed. The nurse explains that the increased fatigue is the result of: 1. Increased metabolism at the cellular level 2. Increased glucose absorption from the intestine 3. Decreased production of insulin by the pancreas 4. Decreased glucose secretion into the renal tubules (Nugent 31) Nugent, Patricia M. Mosby's Review Questions for the NCLEX-RN® Examination, 7th Edition. Mosby, 2011. VitalBook file. - 3 Insulin facilitates transport of glucose across the cell membrane to meet metabolic needs and prevent fatigue. 1 With diabetes there is decreased cellular metabolism because of the decrease in glucose entering the cells. 2 Glucose is not absorbed from the intestinal tract by the cells; fatigue is caused by decreased, not increased, cellular levels of glucose. 4 Filtration and excretion of glucose by the kidneys do not regulate energy levels; if insulin production is adequate, glucose does not spill into the urine.
