Mucous-cont. Agents
| Question | Answer |
|---|---|
| mucous is a | macromolecule |
| mucus strands R crossed linked w/ disulfide bonds= | gel w/consists mostly of H2O around the structure |
| gel w/mostly water surrounding the structure is known as | hydrophilic |
| normal mucous production= | low viscosity & high elasticity (jello) |
| enough water is necessary 4 mucous formation but once formed mucous don't readily incorporate _ _ _ | topically applied water |
| admin. by aerosol or direct instillation 20% 2-3 mL TID or QID 10% 2-3 mL TID or QID | acetylcysteine (mucomyst) |
| breaks disulfide bonds & substitutes its own HS groups 4 disulfide bonds; when theses physical contact w/ moucos it begins 2 < __ | viscosity immediatly |
| Bronchospasms/ N/V / runny nose / airway obstructions are r/t | mucomyst hazard |
| don't use mucomyst for > _ hrs its caustic to airways | 72hrs |
| mucomyst can also be TX 4 _ _ & can be given up 2 10-12hrs pc 2 prevent liver damage | acetaminophen overdose |
| Pulmozyme is a | mucolytic |
| reduces the viscosity secretion that occur w/lung infection by breaking down DNA accumulated in the secretions; mostly used w/ CF Pt | rhDNAse {pulmozyme} |
| there is no evidence that bland aerosols _ mucus to a less _ state | reduce/ viscous |
| using sterile water for; Stridor, croup like cough, hoarseness following extubation, upper airway irritation. Pt discomfort w/airway inst. BYPASSED ^airway | large volume aerosol |
| 4 DX of pneumocystis carinii pneumonia & TB | sputum culture/ induction |
| provide a medium in which secretions can travel through th T-B tree when a PT coughs | Saline bullets |
| increase the amount of fluid in respiratory track the best 1 is water, medullary stimulation/ or bronchial mucus glands | expectorants |
