| Question | Answer |
|---|---|
| What are the non-electrolytes? | amino acids (proteins), glucose, fatty acids |
| What are the major electrolytes? | sodium, potassium, calcium, magnesium, phosphate, chloride, bicarbonate |
| Ions with a positive charge are called? | cations |
| Ions with a negative charge are called? | anions |
| How much of the body's weight is water? | Over half |
| Hypervolemia? | excess of fluid volume present in the body |
| Hypovolemia? | deficiency of fluid volume present in the body |
| Hyponatremia | a deficit of sodium in the blood |
| Hypernatremia | an excess of sodium in the blood |
| Hypokalemia | when blood potassium levels drop below 3.5 mEq/L |
| Hyperkalemia | when blood potassium levels rise above 5.0 mEq/L |
| Respiratory acidosis | when carbon dioxide levels increase |
| Metabolic acidosis | when an excessive loss of bicarbonate ions or increased production or retention of hydrogen ions occur |
| Effects of acidosis | headache, lethargy, weakness, and confusion. |
| Respiratory alkalosis | when carbon dioxide levels decrease, such in the case of hyperventilation |
| Metabolic alkalosis | excess of bicarbonate ions or release of hydrogen ions, can be caused by loss of hydrochloric acid from vomiting or hypokalemia |
| effects of alkalosis | restlessness, muscle twitching, tingling and numbness of fingers, if progresses can cause tetany, seizures and coma. |
| characteristics of tetany | severe muscle cramps, carpopedal spasms, laryngeal spasms, and stridor |
| Using weight to assess fluid balance | A gain or loss of 2.2 lb (1 kg) in 24 hours indicates a gain or loss of 1 L of fluid |
| Expected urine output: | 1000 - 1500 mL/day, report less than 700 mL/day or less than 30 mL/hr |
