| Flashcard | type:basic |
|---|---|
| What is the definition of a "strong ion"? | One that has fully dissociated at a particular pH |
| What is the name that means an ion will have fully dissociated in solution? | A "strong ion" |
| If the strong ion difference is greater than zero in blood then there will be an | Alkalosis |
| If the strong ion difference is less than zero in blood then there will be an | Acidosis |
| Why does infusion of 0.9% saline cause an acidosis? | It increases body chloride stores more than sodium stores, so it decreases the strong ion difference, resulting in an acidosis |
| Why does infusion of hartmanns solution cause an alkalosis | It increases sodium stores, so it increases strong ion difference, resulting in an alkalosis |
| What is the underlying cause of the acidosis in Renal Tubular Acidosis Type 1? | Failure to excrete chloride |
| Are cations positive or negative? | Positive |
| Are anions positive or negative? | Negative |
| Are negative ions anions or cations? | Anions |
| Are positive ions anions or cations? | Cations |
| Is Na+ an anion or a cation? | Cation |
| Is Cl- an anion or a cation? | Anion |
| The normal strong ion difference in blood is about | 40-44mmol/l |
| Does ammonium loss result in an alkalosis or an acidosis? | Alkalosis |

| To calculate the {{c1::strong ion difference}} in blood you take: ({{c2::Na+}} + {{c3::K+}} + {{c4::Ca2+}} + {{c5::Mg2+}}) - ({{c6::Cl-}} + {{c7::Other Strong Anions (lactate)}}) |
|
| The components of {{c1::Stewart's::name of person}} {{c2::Strong Ion Theory::name of theory}} are {{c3::carbon dioxide::component}}, {{c4::strong ions::component}}, and {{c5::weak acids::component}} determine the body fluid's {{c6::acid-base status}} | |
