ANSWERS | GRADE A | 100% CORRECT (VERIFIED
SOLUTIONS) – ANCC
homeostasis - - balance within body that maintains optimal health
- includes body temp, electrolyte balance, ph, fluid, blood volume, nutrition, and elimination
carbon dioxide - - 25 to 30
- maintains acid/base balance
-
carbon dioxide elevation causes - - respiratory acidosis
- compensated metabolic acidosis
- emphysema
- severe vomiting
carbon dioxide decrease causes - - respiratory alkalosis
- DKA
- starvation
- lactic acidosis
- renal failure
- dehydration
calcium - - 9 to 10.5
- maintains muscle contractability
- co-factor in blood clotting
- adds strength to bone and teeth
high calcium causes - - hypothyroidism
- hyperparathyroidism
, - metastatic bone tumor
- addison disease
- prolonged immobilization
low calcium causes - - hypoparathyroidism
- renal failure
- hyperphosphatemia
- hypoalbuminemia
- malabsorption

chloride - - 99 to 107
- maintains electrical neutrality
- major role in fluid balance and renal function
high chloride causes - - diarrhea
- hyperalimentation
low chloride causes - - DKA
- vomiting
magnesium - - 1.3 to 2.1
- facilitates metabolic activities and electrical conductivity
- essential for cardiac, skeletal, and smooth muscle contraction
- cofactor in clotting cascade
high magnesium causes - - renal insufficiency
