NUR206: Fluid & Electrolytes
Study online at https://quizlet.com/_i1hlen
1. Confusion, thirst: What symptoms of a fluid and electrolyte imbalance may be present in older adults?
2. Metabolic rate and heat production: What is 2-3 times higher in infants than in older children or
adults?
3. In ECF: Where are more of an infant's fluids?
4. Few days: How long can you live without water?
5. Percentage of ECF in body: 30
6. Percentage of ICF in bodu: 70
7. Extracellular fluids: Plasma of blood; fluid bathing cells; transcellular fluid and lymph
8. Muscle cells: What cells are rich in water?
9. Solutes: What are solids that dissolve in solvents to form a solution?
10. Solvents: What are liquids that dissolve a solid to form a solution?
11. Water: What is the solvent to compounds in the body with electrolytes and no electrolytes at the solutes?
12. ECF: What brings nourishment to each cell and takes away wastes?
13. 95-108 mEq/L: Normal chloride levels
14. 8.5-10.5 mg/dL: Normal calcium levels
15. 1.5-2.5 mEq/L or 1.6-2.5 mg/dL: Normal magnesium level
16. Phosphate normal level: 1.8-2.6 mEq/L or 2.5-4.5 mg/dL
17. Serum Osmolality (normal range): 280-300 mOsm/kg water
18. Sodium: What is the most abundant electrolyte in the ECF?
19. Sodium (electrolyte): What is needed for muscle contraction and nerve impulses?
20. Hypernatremia: Causes fluids to leave cells and move to the blood, resulting in cell shrinkage/dehydration
= thirst
21. Thirst, dry mucous membranes, weakness, confusion, seizures: What are symp-
toms of hypernatremia?
22. Hyponatremia: deficient sodium in the blood; results from fluid moving to the now higher sodium levels of
the cells causing swelling of cells
23. symptoms of hyponatremia: Confusion, nausea, lethargy, headache, seizures, twitching (from ICP)
24. 98%: How much of potassium is in ICF?
25. 2% of potassium in ECF: What is important for neuromuscular function and acid-base balance?
26. Skeletal, smooth, cardiac muscles: What does potassium affect?
27. Aldosterone: What increases potassium excretion and sodium retention?
28. Sources of potassium: Raisins, dates, bananas, meats/fish, potatoes, spinach, milk
