-
Two theoretical frameworks have been especially
helpful in both understanding the effect of chronic illness and organizing the nurse's response
- Maslow's Hierarchy of Needs
- Chronic Illness Trajectory
-
Maslows Hierchy
- Self actualization
- Self esteem
- Belonging
- safety and Security
- Biological needs
-
Chronic Illness Trajectory
- pre-trajectory- no signs or symptoms
- present
- trajectory onset- symptoms are present, includes diagnostic period
- crisis phase- Life-threatening
- situation
- acute phase- Active illness or complications that require hospitalization for management
- stable phase - Illness
- course/symptoms controlled by regimen
- unstable phase - not controlled by regimen but not requiring hospitalization
- downward - Progressive deterioration in status / increasing disability/symptoms
- dying phase - immediate weeks. days, hours preceding death
Maintaining stable phases is central in the work of managing chronic illness
-
Cardiovascular Disease
- leading cause of death
- second most common cause of disability
-
The American Heart Association identifies the major cardiovascular diseases
- hypertension;
- coronary heart disease (CHD), including myocardial infarction and angina; and
- heart failure (HF)
-
Hypertension. Hypertension (HTN)
- most common
- HTN is diagnosed any time the diastolic blood pressure reading is 90 or higher or the systolic reading is 140 or higher on two separate occasions
Older adults most often have either isolated systolic hypertension or diastolic-systolic hypertension; they rarely have isolated diastolic hypertension
-
Blood Pressure Classification
- Normal <120
- systolic and <80 diastolic
- Prehypertension 120-139
- systolic or 80-89 diastolic
- Stage 1 HIN 140-159
- systolic or 90-99 diastolic
- Stage 2 HTN >160
- systolic or >100 diastolic
-
blood pressure goals
- for all persons > 140/90
- diabetic = > 130/80
-
HTN Etiology
primarily unknown: therefore it is called essential hypertension
Secondary cause are relatively rare in older adults but include pheochromocytoma
-
For Health Maintain:
- Blood pressure : 130/80 Total
- cholesterol <200
- LDL <100
- HDL >40
- Triglycerides<150
-
Coronary Heart Disease
- heart depends on the circulation delivered by the coronary arteries
- conditions that either completely or partially obstruct the blood flow to the heart muscle
- complete occlusion from ischemia is an AMI, or acute myocardial infarction
-
CAD Etiology
- genetic and environmental factors
- arteriosclerosis or atherosclerosis (accumulation of lipid-laden macrophages formation of lesions called plaques)
- Arteriosclerosis is considered an inflammatory condition
-
Signs and Symptoms of CAD
- Chest pain is the most common symptom of CHD
- due to ischemia described as a pressing or squeezing under breast bone
- In elder mild, localized to the back, abdomen, shoulders, or either or both arms.
- Nausea and vomiting or heartburn only
-
Diagnosis of an ischemic event (AMI)
requires documentation of changes in biochemical markers within 24 to 72 hours of the event
-
Chronic ischemic pain
- known as angina, may be intermittent and relieved by nitroglycerine and/or nitrates
- unstable angina ischemic increase in frequency, intensity,
- or duration with less and less provocation (associated with arrhythmias, tachycardia, and
- ventricular fibrillation)
-
remodeling
Chronic CHD, the body attempts to compensate for damage of MI heart enlarges, changes shape leads to a decrease in cardiac pumping, gradual onset of heart failure months or years after the AMI
-
Heart Failure
- Left-sided (diastolic) failure pulmonary symptoms, eventually cause right-sided failure
- right-sided (systolic) failure cardiac output that is inadequate to perfuse the vital tissues.
- definitive diagnosis heart chambers enlargement especially the ventricles.
-
Heart failure Etiology
- damage from hypertension and coronary heart disease
- compensate for the damage, ventricles, enlarges and dilates
- remodeling decreases heart function
-
Myocarciitis
- inflammation of the heart muscle, a condition termed .
- causes:
- viral infections
- bacterial infections
- lupus and other inflammatory diseases.
- Valvular heart disease, regurgitation, increasingly cause of heart failure,
-
Signs and Symptoms Heart failure
- present with exertion, eventually at rest
- periods of "baseline" symptomatology, then periods of exacerbation lead to hospitalization for stabilization with a return to baseline.
-
atypical manifestations of heart failure
- fatigue or sob, orthopnea,
- paroxysmal nocturnal dyspnea, weight gain, and lower extremity edema.
- older adult, symptoms of exacerbations may
- general malaise. Common symptom clusters
- are present for right- and left-sided failure; however, many older adults have both-sided failure, the distinction is not very helpful.
-
Peripheral Vascular Disease
- cluster of disorders vascular insufficiency affects primarily the lower extremities
- peripheral artery disease (PAD) (also called lower extremity arterial disease (LEAD]
- Chronic venous insufficiency (CVI) damaged or incompetent venous walls and valves, vericose viens , deep vein, thrombosis (DVT)
-
claudication.
Pain from intermittent blockage of circulation
-
Etiology: ischemic strokes
- 4 causes are arterial disease, cardioembolism,
- hematological disorders, and systemic hypoperfusion.
-
Cerebrovascular Disease
- occlusion of the vessel lumen from
- thrombus or embolus
- rupture of the vessel
- alteration in vessel permeability, such as changes in bloodviscosity
-
Etiology: Hemorrhagic Events
- uncontrolled hypertension malformations
- of the blood vessels (e.g., aneurysms)
- chronic hypertension causes thickening of the vessel wall,
- microaneurysms, and necrosis.
- Resolution resorption of excess blood
- and damaged tissue.
Hemorrhagic strokes more life threatening but much less frequent than thrombotic strokes.
-
Signs and Symptoms. strokesand TIA
acute neurological deficits
heralded by a severe headache.
- clinical signs and symptoms suggest either
- ischemia or hemorrhage
- hemorrhage
- more focal neurological changes more depressed level of
- consciousness than ischemic stroke.
- Focal changes alternations in motor,
- sensory, and visual
- function; coordination; cognition; and language
-
Symptoms of TIA and Ischemic Stroke
- Sudden weakness or numbness on one side of the body (face, arm, or leg)
- Dimness or loss of vision in one eye
- Slurred speech, loss of speech, difficulty comprehending speech
- Dizziness, difficulty walking, loss ofcoordination, loss of balance, a fall
- Sudden severe headache
- Difficulty swallowing
- Sudden confusion
- Nausea and vomiting
-
Diagnosis of diabetes mellitus
- presentation in elders one of dehydration, confusion, delirium,
- decreased visual acuity. In severe cases, the person may be found obtunded in a nonketotic hyperglycemic-hyperosmolar coma
- plasma glucose 200 mg/dL with symptoms
- OR
- TWO of any combination of positive tests on different days:
- Fasting plasma glucose (FPG) >/=126 mg/dL
- on separate occasions (NOTE: This is not blood glucose levels that are
- obtained with a fingerstick.)
- Oral glucose tolerance
- test (OGTT) >/=200 mg/dL
- 2 hours after glucose
- Random plasma glucose >/=200 mg/dL
- without symptoms
- Diagnosis of impaired glucose tolerance requires:
- Glucose between 141 and 199 mg/dL 2 hours after a glucose challenge
- impaired fasting glucose (IFG) requires:
- Fasting blood glucose between 110 and 125 mg/d1

DM type 2
- non insulindependent diabetes mellitus
- a relative insulinopenia.
- insulin resistance in peripheral tissues
-
Thyroid
- TSH is elevated in hypothyroidism as the pituitary tries to stimulate theunderfunctioning thyroid;
- TSH decreased in hyperthyroidism as the pituitary responds to the elevated blood levels of the thyroid hormone thyroxine (T4)
