Final Exam Study Guide
1. Chemistry 7 Labs
a. Increased hemoglobin, BUN, Creatinine, and Hematocrit can indicate dehydration.
b. Chemistry profiles reveal decreased blood sodium chloride and potassium.
i. Blood Urea Nitrogen (BUN) 8-32: kidney function, high levels of BUN can also be due to
dehydration urinary tract obstruction.
ii. Carbon Dioxide 22-28: Lungs and kidneys, can indicate metabolic alkalosis if too high.
iii. Creatinine 0.6-1.2: Kidney, Hypotension, Hypertension, myasthenia, over-hydration, muscular
dystrophy. Elevated labs can indicate kidney disease.
iv. Glucose 70-100: Can indicate diabetes if labs are high. Pancreatic function
v. Serum Chloride 96-106: kidney disease, heart failure, liver disease
vi. Serum Potassium 3.5-5.0: Heart Rhythm, Kidney Disease, can lead to hyperkalemia
vii. Serum Sodium 135-145: Dehydration, diarrhea, Endocrine disorders, trauma, bleeding,
hypernatremia
2. Acidosis Vs. Alkalosis
a. Acidosis s/s: Hyperventilation, impaired heart function, low blood pressure, coma
i. Treatment:
1. Metabolic: Diabetic Treatment
2. Respiratory: Breathing Treatment
b. Alkalosis s/s: Dizziness, lightheadedness, numbness of hands and feet, confusion, nausea and vomiting
muscle twitching or spasms, low levels of oxygen in blood, seizures, losing consciousness.
i. Treatment:
1. Metabolic: Fluids for fluid loss
2. Respiratory: treating underlying causes of hyperventilation, infection, pain or anxiety
3. Diabetes
a. Type I: Autoimmune dysfunction, insulin dependence
b. Type II: Insulin Resistance
