2217 final review Abbreviations [] ---------concentration w/o-------without w/i--------within BG--------Blood glucose QoL-------Quality of Life b/c---------because r/t----------related to rxn---------reaction Mobility/functional ability Parkinsons and MS (8 questions) 1) Functional Ability: a) Definition: Ability to perform the normal daily activities required to meet basic needs; fulfill usually roles in the family, workplace, and community; and maintain health and well-being i) Cognitive, social, physical, and emotional ability to carry on the normal activities of life. b) Scope: linear, full function to disability i) Varies person to person, varies within an individual at different points in time ii) Lifespan consideration (1) Functional ability changes with development (2) Environment, lifestyle, tech changes require some development (3) Infants and young children’s development is marked with milestones (4) Tests determine developmental delays c) Attributes and criteria: i) Functional ability has two dimensions: (1) Attributes: (a) Defining characteristic of functional ability (2) Antecedent: events that must happen before functional ability can exist (a) Capacity to perform specific functional abilities (b) Actual or required performance of functional abilities (c) Ex. - Physiological process: neural, cognitive, endocrine, musculoskeletal, and metabolic - Acquisition of development milestones and skills (d) At any given time, an individual with the capacity to perform a task or self care activity may not because of developmental, social, environmental or cultural factors (3) Also categorised by gradations of capacity or performance (a) Not just what they can or do but with what and how much, and what effort of assistance they do it with, and their effort is. d) Context to Nursing and Health Care i) 3 major dimensions of concern (1) Risk recognition (a) Essential to early identification of factors that affect function (b) Actual deficiency leads to use of resources and support (c) The earlier the ID the better the health outcomes (d) Types f risks: (i) Developmental abnormalities, physical or psychological trauma or diseases, social and cultural factors (beliefs and perception of health), physical environment. (ii) Comorbidities and socioeconomic factors (iii)Preclinical disability: task modification w/o report of difficulty in performing a specific activity in elderly (iv) Postpartum depression (v) Acute illness or worsening of chronic disease (2) Functional assessment (a) Time-intensive, interprofessional effort using multiple tools (b) Indicated in certain circumstances (c) Ex. Children who are it’d with developmental delays are referred to assessment across domains including adaptive behaviour (functional ability). (d) Best to observe the function of the client (e) Elderly: indicated when there has been a loss of functional ability or a change in mental status, multiple health conditions, or frail living in the community (f) Assessment tools: (i) Self-Report 1. Patients’ perception 2. Potential for inaccurate measurement a. Affected by personal characteristics, preference, and environmental factors, interpretation (ii) Performance based 1. Actual observation of a standardized task 2. SF-36 – physical, social, mental domains of elderly 3. Functional Assessment Screening Tool (FAST-16)- social and behavioural young adults (3) Planning and delivery of individualized care appropriate to level of ability (a) Care Delivery: cross section of help needed and how much help the pt needs to optimize independence ii) Alterations occur as primary or secondary problems (1) Primary problems- ability never developed (2) Secondary problems- loss of ability e) Functional performance is the actual parts of the functional ability a person does in a day 2) ADL a) (Basic) activities of daily living b) Personal care, mobility, eating, hygiene, grooming, bathing, mouth care, dressing, toileting, 3) Instrumental activities of daily living a) More complex skills for living in the community b) Managing money, grocery shopping, cooking, house cleaning, laundry, medicating, telephone, accessing transportation, 4) Independent ADL Parkinsons Pathophysiology - Pathology o Neurological disorder b/c loss of dopamine producing cells in the brain results in motor disability o Degeneration of the dopamine-producing neurons in substantia nigra of the midbrain o Disrupts normal balance of dopamine and AcH in basal ganglia - Most common in 50+ men - Exact cause unknow - Aggregation of Lewy body proteins in brain - Not considered hereditary but 10% can be linked - Risks: o Well water exposure o Pesticides o Herbicides o Industrial chemicals o Wood pulp mill exposure o Lack of dopamine can cause development o Clinical - Symptoms: Manifestations o Gradual, ongoing o Can start unilaterally o Do not occur until 80% of neurons in substantia nigra are lost o Primary symptoms: Tremors First sign Minimal at first so pt might be the only one who notices it Affects handwriting More prominent at rest Worsened by emotional stress or increased [] Pill rolling Diaphragm, tongue, lips and jaw Rarely head shake Rigidity Increased resistance to Passive ROM Jerky (cog-wheel rigidity) Sustained contraction can cause rigidity and muscle soreness (tired and achy), pain in head, upper body, spine, or legs Slow movement as a result b/c of alternating contraction and relaxation in opposing muscle groups is inhibited Akinesia Absence or loss of control of voluntary muscle movement Bradykinesia (slowness of movement) is especially prevalent in the loss of automatic movement b/c of physical and chemical changes in the basal ganglia In unaffected patients, automatic movement is involuntary and subconsciously (blinking, swinging arms, swallowing, saliva, facial and hand movements for expression, and minor movements to adjust posture In pt with PD does not perform these movements and lack natural activity (stooped posture, masked facial expression, drooling, and shuffling gait Postural instability Can’t stop Pull test- pt will fall o Other symptoms: Depression, anxiety, apathy, fatigue, pain, urinary retention, constipation, ED, memory changes, sleep disorders o Subtle and mild to more pronounced o Lead to abnormal brain functioning which effects cognition, mood, behaviours o Dopamine is essential for normal function of extrapyramidal motor system (posture, support, voluntary movements) o Early Mild tremor, slight limp, decreased arm swint o Mid-later Shuffling gait, near impossible to stop, flexed arm.

Concept: Glucose regulation; topics Type 1 & Type 2 diabetes (7 questions) - Definition: o The process of maintaining proper blood glucose balance/ optimal levels o Balance between nutritional intake, hormone signalling, and glucose uptake by the cell Glucose enters the cell, and it is oxidized through cellular respiration into ATP for energy Efficiency of glucose metabolism is signified by the blood glucose levels - Scope: o Hypoglycemia < 70 mg/dL o Euglycemia Fasting euglycemia= 70-99 mg/dL 2hr-postprandial state= 100 -140 mg/dL o Hyperglycemia > 100 mg/dL fasting > 140 mg/dL 2hr-postprandial - Normal Physiology o Insulin is produced by the beta cells of the islet of Langerhans in the pancreas to lower the blood glucose by allowing the cells to be more permeable to glucose (increases uptake) After eating, insulin will be released b/c of increased glucose Binds to the cell walls and signals glucose transporter molecules to help glucose enter the cell Insulin supresses the secretion of glucagon and facilitates glycogen storage o Counterregulatory hormones are produced to increase BG if increased demand Result in utilizing glycogen stores Increase with stress related conditions (physical and emotional) Glucagon is released when there is low cellular glucose Suppresses insulin and stimulates hepatic glucose production from glycogen Cortisol Growth hormone Epinephrine/norepinephrine Steroid medications and stress also cause gluconeogenesis (creation of glucose when stores are low) Increase risk of muscle mass loss - Risk factors: o Populations at risk: Pregnant women Pregnancy and the associated hormone changes State of insulin resistance Higher hyperglycemia risk (especially postprandial hyperglycemia) Infants: (larger infants’ higher risk?) Older adults: Greater risk b/c of increased visceral fat and decreased lean muscle Often also age-related insulin reduction Reduced capacity to regulate and metabolize glucose [] Racial/ ethnic groups Greater genetic predisposition to insulin resistance = increased risk for T2D Nativ/ Aboriginal “American Indian/Alaskan natives” in Giddens African Americans Hispanics/ Latinos o Puerto Ricans and Mexican Americans having the highest of subclass Asian Americans More prominent in communities with less infectious diseases but have a sudden increase of noncommunicable diseases and urbanization that results in more sedentary lifestyles Europe have a genetic tendency for the autoimmune form of diabetes o Individuals at risk Genetic factors HLA genes for T2D Fam Hx of T2D, Obesity, or other metabolic syndrome factors Lifestyle risk factors Promote and worsen insulin resistance o Poor diet, (high trans and saturated fats) o Excess calorie intake leading to obesity o Low fiber high carbs o Lack of physical activity Medications o Most common: Insulin and oral antihyperglycemic agents (sulfonylurea) Corticosteroids Estrogen ACE Inhibitors Beta-blockers Potassium-depleting diuretics Bronchodilators Antipsychotics Antibiotics - Hypoglycemia o Low BG because of insufficient nutrients intake, medications, excessive exercise, or other dx. o Combo of factors Insufficient nutrient intake Malnutrition depletes glycogen stores in liver and adipose tissues This prevents the hepatic mechanisms from maintaining normal BG levels Free fatty acids are mobilized as substrates for glucose production and produces ketones Eventually life-threatening Adverse rxn to meds Inappropriate dosing of exogenous insulin or sulfonylurea which increases endogenous insulin create a regimen with a client who needs insulin to ensure you avoid hypoglycemic episodes Excessive exercise During exercise, energy in muscle cells is used up first then glucose form hepatic and circulatory systems are used which lowers BG After an exercise the body replenishes the cells glucose levels to restore the ATP which also further lowers BG, called a lag effect. o Consequences Mild nervousness, irritability, diaphoresis, anxiety, palpations Neurological changes, seizures, LOC, Death Recurring hypoglycemia makes the counterregulatory hormones more sensitive Symptoms of hypoglycemia don’t occur until the BG is dangerously low Risk of fatality is 4-10% Hypoglycemia unawareness - Hyperglycemia: o High BG b/c: Insufficient insulin production/secretion b/c glucose can’t enter the cells damage to the b cells is usually caused by an autoimmune response with genetic disposition or can be secondary from pancreatitis or pancreatic cancer Excessive counterregulatory hormone production Increased cortisol can be caused by stress, pain, sleep disturbances, acute injury or illness o Also, can occur with medication(corticosteroids) o Cushing’s disease o Exacerbate insulin resistance o Increase insulin dose Or deficient hormone signalling Body cells respond abnormally to the signalling action of insulin and do not allow glucose into the cells Receptors or transporter molecules are limited o Consequences: Proinflammatory (contributes to atherogenesis and plaque formation) Increases cancer risk Hypertension 50% of pt w T1D 80% of pt w T2D o High oxidative stress and inflammation o Reduced elasticity of the blood vessels Angiopathy b/c of Longstanding uncontrolled high glucose levels damage to blood vessels o theories: byproduct of glucose metabolism (sorbitol) formation of abnormal glucose molecules in basement membrane of small blood vessels (like in eye or kidneys) oxidative stress in RBC leads to decreased oxygenation Microvascular: damage basement membranes of small blood vessels in lower extremities o b/c thickening of blood vessels membrans in capillaries and arterioles can happen in T2D o specific to DM o Impaired adequate oxygenation of tissues o loss of protective sensation o microangiopathy: Diabetic neuropathy Most common complication (50% of pt) Difficulty managing pain and a leading cause of nontraumatic amputation which reduce QoL Loss of protective sensations in feet Balance troubles (fall and fractures) Risk factors: o Long standing poor glycemic control o Smoking o Alcohol o Metabolic abnormalities (hyperlipidemia and hypertension) Neuropathy: chronic kidney disease that can lead to end stage liver dx o Risk factors: smoking, hyprertension, genetic predisposition, chronic hyperglycemia o Kidney disease can be reduced w Norm ranges of glucose control o Haggressive BP management for all DM Pt Ace inhibitors Angiotensin 2 receptors Given for Pt wto prevent Yearly screening Types o Peripheral neuropathy High BG is toxic to nerves so it causes numbness and tingling and burning when the nerves get damaged Increases risk of foot ulcers because protective sensations are gone Can be seen with prediabetes and be the presenting symptom of impaired glucose utilization o Sensory neuropathy Onset: Symmetrical, distal, sensory neuropathy Damage to small nerve fibers results in loss of dermal sensation Large nerve fibers loss of touch and vibrational sensation Sensory fibers = paresthesia and pai Prevention/ Nursing action Visually inspect feet at each visit and assess loss of protective sensation, well fitting shoes, ulcers Test: 10g monofilament test (10g of force to make the filament buckle inn 4 areas of planter surfaces of foot) Assess vibratory sense 128Hz tuning fork on tip of big toes (if pt unable to feel while you can it is abnormal) Intact peripheral pulses Tx.
