| Question | Answer |
|---|---|
| nasal cannula | 1-6 L/min if the patient requires low to medium 02 |
| simple face mask | 5-10 L/min; 40-60% if pt needs moderate 02; does not deliver certain percent |
| venturi mask | 4-6 L/min; 24-60% most reliable and accurate (colored mask) |
| non-rebreather | minimal flow rate of 10 L/min; up to 90% more accurate flow rate, one way valve to prevent room air from entering, bag must be inflated |
| endotracheal tube (ETT) | connected to a ventilator for patient's who cannot breath for themselves per MD order |
| perfusion | 02 to and away from tissues |
| ventilation | mechanical act of breathing |
| transport | rbcs carrying 02 to CO2 |
| components of a pulmonary assessment | activity tolerance, breathing patterns, respiratory effort |
| PNEUMONIA priority assessments | TEMP (infection getting better/worse), 02 sat, RR, decreased/diminished lung sounds where infection is, resp effort and pattern (should not have any MAJOR distress, assess any secretions) |
| COPD priority assessments | o2 sat (may be chronically low), RR (O2 + RR together indicate level of distress!!), adventitious sounds like wheezing, rhonchi, crackles (you will not hear normal lung sounds), resp effort + pattern, activity tolerance!!, anxiety may indicate decline |
| ANEMIA priority assessments | only one with no heart.lung abnormals!!, o2 sat (needs to be good bc lack of RBC), RR, BP (if blood loss), HR (compensation), SOB, weak, pale (especially mucus membranes) |
| DVT/PE priority assessments | o2 sat (will drop if severe), RR, BP (will increase if severe to compensate for o2 sat), for acute PE (HR+BP will elevate first and as it worsens will drop), no heart + lung abnormals if stable, if unstable will see crackles (obstructions of vessels) |
| DVT s/s | redness, edema, pain in limb |
| PE s/s | breathing pattern and resp effort!! sob, chest pain, dizziness, inc HR/BP to comp for lack of o2, low o2 sat |
| COPD labs | priority: ABGS (is paCO2 elevated? is ph stable?) other: CBC (r/o infection), BMP (assess for complications) |
| PNEUMONIA labs | priority: CBC (to assess WBCs + neutrophils) other: ABGs (if unstable), BMP (is anything else abnormal?) |
| ANEMIA labs | priority: CBC (assess RBCs, Hgb, Hct, presence of sickle cells) other: BMP (assess for any other complications) |
| DVT/PE labs | priority: PT/INR, PTT (monitor anticoagulants), d-dimer (clotting) other: ABGS (if unstable, esp with PE), CBC/BMP (assess for complications) |
| COPD interventions | use o2 cautiously (NC is stable, venturi if in distress), space activites to decrease fatigue, PO intake, low IV fluids, steroids, bronchodilators, Incent. Spir., high calorie, small frequent meals |
| PNEUMONIA interventions | o2 depending on sat, rest but ambulate with frequent breaks, IV+PO fluids (fever+infection = dehydration), antibiotics!! guaifenesin (thins secretions), mild/dull CP is expected, need balanced regular diet, nutrition fights infection, incent. spir.!! |
| ANEMIA interventions | (supplemental o2) 1-6 L NC, want to maintain sat of 92 or greater, activity as tol., give packed RBCs, meds for the cause (b12, folic acid, etc.), pain not normal, need balanced regular diet or possibly increase foods with the cause of anemia, |
| DVT/PE interventions | yes o2 (anything from NC to vent), VERY restricted activity (in DVT prevent dislodge of clot, PE avoid inc o2 demand), give heparin (PTT), warfarin (PT/INR), enoxaparin, dabigatran, pain expected with DVT (site) and PE (cp), diet = no changes w/ leafy gre |
| what may indicate that a DVT has turned into a PE? | sudden, sharp pain in the chest |
| bronchoscopy | to examines airway and obtain biopsies, used for people with gas exchange disorders, risks are mostly associated with biopsy procedure so perforation, bleeding, pneumothorax |
| what does a normal MCV indicate? | blood loss due or anemia related to a chronic disease |
| what is a normal level for MCV? | 80-95 |
| what does a low (small) MCV indicate? | iron deficiency (less than 80) |
| what does a high (large) MCV indicate? | b12 deficiency (greater than 95) |
