119
Chronic bronchitis
Deals with the bronchioles - productive thick mucus - rhonchi - wheezing - ABG: hypercapnia, hypoxemia - inspiratory dysfunction - increased RBC production (b/c chronic and trying to get air) Tx: - fluids, expectorant airway clearance - steroids Important to note: - respiratory acidosis - high risk for infections - expiratory dysfunction - tripod position
120
Emphysema
Pink, squishy lung tissue - no cough (complications w/ infections develop) - no adventitious breath sounds Alveoli: pink squishy: overinflated - decreased elasticity - CO2 gets trapped Pursed lipped breathing to get CO2 out - hypercapnia - 88-92% O2 levels the sweet spot so they keep breathing Important to note: - respiratory acidosis - high risk for infections - expiratory dysfunction - tripod position
121
What is the NADIR period
Period of time, about 7-10 after starting chemo, where the patient will have the lowest blood cell counts - exact onset depends on drug regimen
122
Lab values in hematology: hemoglobin and hematocrit
Hgb: 12-16 in females, 14-18 in males - measures oxygen carrying capacity of RBC Hct: 37-46% F; 42-52% M - %age of RBC compared to total blood volume Decrease in H&H, RBC seen with anemia, hemorrhage, hemodilution Increase in H&H, RBC seen w/ polycythemia or hemoconcentration
123
Lab values in hematology: Platelet count
150,000-400,000/microL - counts less than 100K indicate thrombocytopenia - thrombocytosis: too many platelets, occurs w/ inflammation/cancer
124
TACO - who is at risk for developing
A person w/ cardiac or renal insufficiency is at risk for developing circulatory overload - especially true if large quantity of blood is infused in a short period, particularly in an older patient

Is a type of arthritis caused by the deposit of uric acid crystals into 1 or more joints Causes: when either kidneys cannot excrete uric acid; too much is made; metabolic syndrome contributes
126
Symptoms of gout
dusky, cyanotic, extremely tender and swollen
127
Dx and Tx for gout
Dx: H&P, synovial fluid aspiration finding urate crystals Tx: - acute attack: treating pain & inflammation - future attacks prevented by drug therapy, weight loss, adequate hydration, limited alcohol and red/organ meats
128
Prehypertension measurements
Systolic: 120-139 Diastolic: 80-89 Vital signs monitored regularly to see if HTN remains consistent and necessary lifestyle modifications should be applied
129
Treatment for Hypertension
Tx is aimed at removing or treatment cause Lifestyle modifications: - weight reduction - DASH diet - decrease sodium, moderate alcohol - physical activity - avoid tobacco products - manage risk factors Drug therapy to decrease blood volume and reduce vascular resistance: - adrenergic blockers (AB and BB) - ACE inhibitors (-prils) - ARBs (-sartans) - CCBs (-pine) - direct vasodilators - diuretics
130
Treatment for CAD
Can be prescribed to modify risk factors and reduce the onset/progression of disease, but need lifestyle changes - activity and dietary changes - smoking cessation - medications to regulate modifiable risk factors -- BP meds -- lipid lowering drug therapy -- drugs that restrict production of lipoproteins or increase removal of lipoproteins
131
Angina vs chest pain with MI: Chronic stable angina
Is a clinical manifestation of CAD - refers to chest pain that occurs intermittently over long period w/ same pattern of onset, duration, and intensity Is transient (reversible) chest pain that occurs when heart muscle becomes ischemic during exertion or increased cardiac activity - subsides when precipitating factor is resolved and/or when NTG is provided - no permanent injury to cardiac cells occurs
132
Angina vs chest pain with MI: Unstable angina (UA)
Occurs when ischemia is prolonged (more than 30 minutes) and no immediately reversible "intermittent" - ACS (acute coronary syndrome): develops and include spectrum of UA - NSTEMI - STEMI: ST-segment-elevation MI (worse damage to ST interval - total occlusion) High risk for developing an MI and must be treated aggressively
133
Angina vs chest pain with MI: UA and MI
High risk for developing an MI so must be treated aggressively - MI occurs as a result of sustained ischemia, causing irreversible cell death of myocardium - contractile function of heart stops in areas of necrosis - degree of altered function depends on area of heart involved and size
134
Assessment for stroke: primary assessment and if patient is stable
Primary assessment focuses on cardiac, respiratory, and neurological status If patient is stable, obtain symptoms, onset, duration, nature and changes: - history of any similar symptoms - current medications - hx of risk factors & other illnesses - FHx of stroke, aneurysm, or CV disease
135
