Test 1
| Question | Answer |
|---|---|
| Healthy cellular adaptations | hypertrophy, atrophy, hyperplasia |
| Pathologic cellular adaptations | dysplasia, neoplasia |
| Causes of cellular injury/death | apoptosis, hypoxia, free radicals, infection, trauma |
| Function of ADH | retains water; pituitary gland; decreased urine output |
| Function of Aldosterone | adrenal gland; reabsorption of sodium--water follows |
| Signs of dehydration | dry mucous membranes, skin tenting, low BP, weak pulse, ^hematocrit |
| Sodium | cation; extracelluar; nerve impulses |
| Normal levels Na | 135-145 mEq/L |
| Signs of hyponatremia | less nerve conduction; fatigue; muscle weakness; cell swelling; headache; confusion |
| Signs of hypernatremia | cellular dehydration; thirst; edema; low urine output; nerve conduction problems |
| Potassium | cation; intracellular; regulate intracellular fluid volume; nerve impulses; |
| Normal levels K | 3.5-5.0 mEq/L |
| Effects of hypokalemia | cardiac dysryhtmias; neuromuscular weakness |
| Effects of hyperkalemia | cardiac dysryhtmias; neuromuscular weakness |
| Calcium | extracellular; cation; nerves, blood clotting, metabolic functions |
| Normal levels Calcium | 8-10.5 d/L |
| Effects of hypocalcemia | increased nerve excitability- tetany; cardiac dysrhythmias |
| Effects of hypercalcemia | decreased nerve excitability; polyuria; cardiac dysrhythmias; bone effects |
| Body's 1st line of defense | skin and body secretions |
| Body's 2nd line of defense | inflammatory response (vasodilation, WBCs, phagos) |
| Body's 3rd line of defense | immune response (cell and humoral mediated) |
| Specific line of defense | 3rd- immune response |
| Nonspecific line of defense | 1st and 2nd- skin/body secretions and inflammatory response |
| Phagocytic cells | neutrophils and macrophages |
| 4 cardinal signs of inflammation | 1) redness/warmth 2) swelling/edema 3) pain 4) loss of function |
