disability

  • restriction or lack of ability to perform an activity in a normal manner; the consequences of impairment in terms of a person's functional performance and activity

  • ex. cerebral palsy, spinal cord injury, Down syndrome

New cards
2

developmental disability

  • those that occur any time from birth to 22 years of age and result in impairment of physical or mental health, cognition, speech, language, or self-care

  • some occur as a result of birth trauma or severe illness or injury at a very young age, whereas many developmental disabilities are genetic in origin

  • ex. spina bifida, cerebral palsy, Down syndrome, muscular dystrophy, dwarfism, and osteogenesis imperfecta

New cards

  • Risks associated with sensory disabilities include isolation, reduced cognitive function, poor physical and psychological health, and increased risk of falls and hospitalization

  • can be age related

New cards
6

chronic illness

  • the experience of living with a chronic disease or condition; the person's perception of the experience and the person's and others' responses to the chronic disease or condition

  • Americans living in rural communities are more likely to have chronic illness

  • anything over 6 months

  • do not always have a root cause

  • Exacerbations cause baseline to lower

New cards
7

New cards
8

models of disability

  • Interface Model

  • Medical Model

  • Rehabilitation Model

  • Biopsychosocial Model

New cards
9

interface model of disability

  • looks at removing barriers to disability

  • considers rather than ignores the diagnosis

  • person with a disability, rather than others, defines the problems and seeks or directs solutions

  • model aims to enhance inclusivity and participation for individuals with disabilities

  • most appropriate for nurses

  • promotes the view that people with disabilities are capable, responsible people who are able to function effectively despite having a disability

New cards
10

medical model of disability

  • equates people who are disabled with their disabilities and views disability as a problem of the person, directly caused by disease, trauma, or other health condition

  • management of the disability is aimed at cure or the person's adjustment and behavior change (interventions might involve surgery, medications, etc. with the goal to minimize or eliminate the impairment)

  • viewed as promoting passivity and dependency

  • people with disabilities are viewed as tragic

  • health care providers, rather than people with disabilities, are viewed as the experts or authorities

  • not a focus on living independently with the disability.

New cards
11

rehabilitation model of disability

  • regards disability as a deficiency that requires a rehabilitation specialist or other helping professional to fix the problem

  • emerged from the medical model

  • people with disabilities are often perceived as having failed if they do not overcome the disability.

New cards
12

social model of disability

  • views disability as socially constructed and as a political issue that is a result of social and physical barriers in the environment

  • idea that disability can be overcome by removal of these barriers

New cards
13

biopsychosocial model of disability

  • integrates the medical and social models to address perspectives of health from a biologic, individual, and social perspective

  • this model looks at everything (biological, psychological, and social); treatment aims to treat all three domains

  • this model is critiqued as still focusing on the disabling condition rather than the person's experience with the disability

New cards
14

people first language

  • referring to the person first: "the patient with diabetes" rather than "the diabetic" or "the diabetic patient

  • conveys the message that the person, rather than the illness or disability, is of greater importance to the nurse.

New cards
15

multiple chronic conditions (MCC)

  • increases the complexity of care and often necessitates care by multiple health care specialists, a variety of treatment regimens, and prescription medications that may not interact

New cards
29

heart failure

  • atherosclerosis of the coronary arteries is a primary cause of HF

  • CAD is found in the majority of patients with HF

  • when the left ventricle fails, increased fluid pressure is transferred back to the lungs causing damage to the right side of the heart

New cards
30

congestive heart failure

  • failure of both the right and left ventricle

  • when the left ventricle fails, increased fluid pressure is transferred back through the lungs, leading to damage of the right side of the heart

  • When the right side loses pumping power, the blood backs up in the body's venous system

New cards
31

  • An expected EF is 55% to 65%

  • heart failure with reduced EF (systolic HF) - HFrEF --- EF 40% or less

  • heart failure with preserved EF (diastolic HF)- HFpEF --- EF 50% or greater

  • Ischemic rest pain is usually worse at night and often wakes the patient

New cards
53

venous issues

  • Warm packs applied to the affected extremity reduce the discomfort associated with DVT.

  • The legs should be elevated frequently throughout the day (at least 15 to 20 minutes four times daily). At night, the patient should sleep with the foot of the bed elevated about 15 cm (6 inches)

  • Prolonged sitting or standing in one position is detrimental; walking should be encouraged

  • patient should avoid placing pressure on the popliteal spaces, as occurs when crossing the legs or sitting with the legs dangling over the side of the bed

  • Compression of the legs with graduated compression stockings reduces the pooling of venous blood

  • Oral iron is best absorbed on an empty stomach- take 1-2 hours before meals

  • antacids and dairy products should be avoided with iron as they can greatly diminish its absorption

  • Oral iron replacement therapy may change the color of the stool but should not cause a false-positive result for occult blood on stool analysis.

Vitamin B12 deficiency

  • can occur in patients with disorders such as inflammatory bowel disease, or in patients who have had GI surgery such as ileal resection, bariatric surgery, or gastrectomy

  • dairy, red meat, eggs, fish, fortified cereal

New cards
88

thrombocytopenia

  • When platelet counts fall to 20,000/mm3 or less, petechiae may occur

  • The most common cause of increased platelet destruction is immune thrombocytopenic purpura

  • promote safety and it should include fall prevention, particularly for older adults and those who are frail.

New cards
89

ITP nurse management

  • common signs of thrombocytopenia include easy bruising, heavy menses, and petechiae on the extremities or trunk

  • H. pylori infection is associated with ITP

  • sulfa-containing medications and others may interfere with platelet function (e.g., aspirin, NSAIDs)

  • nurse must assess for a history of recent viral illness and reports of headache, visual disturbances, and other symptoms that may indicate intracranial bleeding

  • neurological assessment should be performed

  • Patient and family education should address signs of exacerbation (e.g., petechiae and ecchymoses)

  • Bone mineral density should be monitored, and patients may benefit from supplemental calcium, vitamin D, and bisphosphonate to reduce risk for significant bone disease

New cards
90

ITP patient teaching

  • avoid asprin and NSAIDS (contain sulfa)

  • avoid constipation, straining, and vigorous flossing of the teeth.

  • electric razors should be used for shaving and soft-bristled toothbrushes should be used for dental hygiene

  • patients and their partners should be counseled to avoid vigorous sexual intercourse when platelet counts are low

  • increase in fatigue

New cards
91

HIT nurse management

  • immediate cessation of heparin and initiation of another form of anticoagulation

  • Monitor platelet count for all clients receiving heparin (drop 50% of baseline

  • Argatroban, a thrombin inhibitor, is an FDA-approved anticoagulant for the treatment of HIT

  • Education of need to avoid heparin products as can reactivate

New cards
92

blood transfuion reaction s/s

  • fever

  • chills

  • respiratory distress

  • low back pain

  • nausea

  • pain at the IV site,

New cards
93

blood administration procedure

  • determine the clients previous history (allergies and previous transfusion reactions)

  • Assess the client, obtain vital signs for baseline, and teach signs of a transfusion reaction and how to call for help.

  • Set the infusion pump to deliver blood over 2-4 hours as prescribed but NO LONGER THAN 4 hours

  • Rapid infusion of the blood puts the client at greater risk for transfusion reaction and fluid volume overload.

  • monitor pt during the first 15 min for reaction

New cards
94

steps to take if there is a reaction

  • Stop

  • Assess

  • Notify primary provider and implement prescribed treatments. Continue to monitor

  • Return blood

  • Obtain any samples needed

  • Document

New cards
95

asthma

  • symptoms are cough, dyspnea, and wheezing

  • As the exacerbation progresses, diaphoresis, tachycardia, and a widened pulse pressure may occur along with hypoxemia and central cyanosis (a late sign of poor oxygenation), chest tightness

  • symptom control includes using immediate intervention to diminish bronchoconstriction, which prevents increased anxiety resulting from progressive dyspnea

  • poor symptom control increases the risk of exacerbations

New cards
96

complications of asthma

  • status asthmaticus

  • respiratory failure

  • pneumonia

  • atelectasis

New cards
97

status asthmaticus

  • labored breathing, prolonged exhalation, distended neck veins

  • wheezing (as the obstruction worsens, the wheezing may disappear; this is frequently a sign of impending respiratory failure.

  • patient is treated initially with a short-acting beta-2-adrenergic agonist first then corticosteroids

  • patient requires supplemental oxygen (partial or complete non-rebreathing mask) and IV fluids for hydration (to treat dyspnea, central cyanosis, and hypoxemia)

  • increasing PaCO2 (to normal levels or levels indicating respiratory acidosis) is a danger sign signifying impending respiratory failure.

  • NO SEDATIVES

  • can give magnesium sulfate (smooth muscle relaxation)

New cards
98

nursing management for status asthmaticus

  • monitors the patient for the first 12 to 24 hours, or until the severe exacerbation resolves.

  • assesses the patient's skin turgor for signs of dehydration

  • patient's energy needs to be conserved, and his or her room should be quiet and free of respiratory irritants, including flowers, tobacco smoke, perfumes, or odors of cleaning agents

New cards
99

quick relief asthma medications

  • beta2-adrenergic agonists (albuterol, levalbuterol, pirbuterol)

  • anticholinergics (ipratropium)

New cards
100

long acting asthma medications

  • Corticosteroids

    --- decrease peak flow variability

    --- inhaled Long-acting beta2-adrenergic agonists Leukotriene modifiers

    --- montelukast, zafirlukast, and zileuton
