Brief exposure rarely causes infection. Transmission usually requires close, frequent, or prolonged exposure. Cannot be spread by hands, books, glasses, dishes, or other fomites. Inhaled bacilli pass down bronchial system and implant themselves on bronchioles or alveoli. Multiply with no initial resistance. Replicates slowly and spreads via the lymphatic system Clinical Manifestations Insidious Low grade fever, night sweats, fatigue, weight loss Diagnostic Studies TB skin test, CXR Bacteriological studies Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 o Stained sputum smears examined for acid-fast bacilli} Required for diagnosis o QuantiFERON-TB (QFT) Rapid blood test (few hours) Does not replace cultures Reported to public health Contact with others, immunocompromised, substance abuse Nursing Assessment Assess for o Productive cough o Night sweats o Afternoon temperature elevation o Weight loss o Pleuritic chest pain o Crackles over apices of lungs Nursing Diagnosis o Ineffective airway clearance related to copious excessive mucus, retained secretions Risk of infection (of others) as evidenced by insufficient knowledge to avoid exposure to pathogens Ineffective health management r/t insufficient knowledge of therapeutic regimen, insufficient support Planning Goals o Comply with therapeutic regimen. o Have no recurrence of disease. o Have normal pulmonary function. o Take appropriate measures to prevent spread of disease. Comply with the therapeutic regimen Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 No reoccurrence of disease Have normal pulmonary function Take appropriate measures to prevent the spread of the disease Nursing Implementation Health Promotion Ultimate goal in Canada is eradication o Selective screening programs in high-risk groups to detect TB o Identify contacts of patient with TB Acute intervention o Airborne isolation o Receive 4 drug therapy o Immediate medical workup Teach client o Cover nose and mouth with tissue when coughing, sneezing, or producing sputum o Handwashing after handling sputum-soiled tissues Ambulatory and home care o Ensure that patient can adhere to treatment. o Teach symptoms of recurrence. Evaluation Expected outcomes o Complete resolution of disease o Normal pulmonary function o Absence of any complications o No transmission of TB Pneumothorax Occurs when air enters the pleural space Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 May be due underlying disease (bleb in COPD) or a wound in chest wall (surgery, trauma, procedures) Tension pneumothorax is a life-threatening complication Pneumothorax: Manifestations Degree depends on size and cause of pneumothorax o Sudden pleuritic pain o Dyspnea o Tachypnea, tachycardia o Anxiety o Air hunger/ respiratory distress o Accessory muscle use o Decreased or absent breath sounds o Altered chest wall movement Collaborative Care Depends on cause/severity Goal is to remove air from pleural space Aspiration of pleural space Chest tube with drainage device connected suction and with a water seal Oxygen as needed Pain management Antibiotics if required Pneumothorax: Manifestations Degree depends on size and cause of pneumothorax o Sudden pleuritic pain o Dyspnea o Tachypnea, tachycardia o Anxiety Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 o Air hunger/ respiratory distress o Accessory muscle use o Decreased or absent breath sounds o Altered chest wall movement Chest Tubes Tube inserted between ribs into pleural space Attached to water-sealed drainage system to remove extra air or fluid from pleural space using negative pressure May be connected to suction if ordered Daily CXR required Obesity and Care of the Bariatric Client Manifests as an abnormal increase in the proportion of fat cells Primarily occurs in the visceral and subcutaneous tissues of the body Complex interaction of genetic, nutritional, physiological, psychological, behavioural, environmental, and social factors that create imbalance between energy expenditure and energy intake increasing evidence that obesity is not a problem resulting from a lack of willpower and self-control but, instead, is a pervasive, progressive, and serious chronic condition that is strongly associated with a variety of comorbid conditions and has a major effect on the physical, mental, social, cultural, and economic health of those affected. Classifications of body weight and obesity Primary or secondary obesity Excess caloric intake for the body’s metabolic demands (primary obesity) Results from various congenital anomalies, chromosomal anomalies, metabolic problems, or CNS lesions and disorders (2 nd Obesity) Body mass index (BMI) Degree to which a client is classified as underweight, healthy (normal) weight, overweight, or obese Common clinical index of obesity or altered body fat distributio Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 BMI of 30–40 kg/m2 classified as obese BMI of more than 40 kg/m2 classified as morbidly obese Waist circumference Hip circumference Waist-to-hip ratio (WHR) Less than 0.80 is optimal Body Shape Android obesity: Apple Gynoid obesity: Pear Genetics play an important role in determining body fat distribution patterns. Etiology Genetic–biological basis Environmental factors, Psychosocial factors Energy intake exceeds energy output. Processes leading to obesity are much more complex and still undergoing investigation. Causes of obesity involve significant genetic–biological susceptibility factors highly influenced by environmental and psychosocial factors Health Risks Associated with Obesity Cardiovascular problems Respiratory problems Diabetes mellitus Gastrointestinal and liver problems Psychosocial issues Nursing and Conservative Collaborative Management: Obese Clients Nursing assessment Client may withhold information out of embarrassment or shyness Provide acceptable reasons to client for personally intrusive questions Respond to concerns about diagnostic tests Interpret outcomes Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 Size Appropriate Equipment Needs for Patient and Nurse Safety Commodes and wheelchairs Stretcher, scales Bed, chair, bedpans Blood pressure cuff, pulse oximetry Nursing assessment Health history Time of obesity onset Diseases related to metabolism and obesity Medications Objective Height, weight, BMI, waist circumference Nursing diagnoses Obesity Impaired skin integrity Ineffective breathing pattern Chronic low self-esteem Planning: goals Modify eating patterns. Participate in a regular physical activity program. Achieve weight maintenance or loss to a specified level. Maintain weight loss to a specified level. Minimize or prevent health problems related to obesity. Nursing implementation When no organic cause can be found for obesity, it should be considered a chronic, complex disease. Supervise a plan: Successful weight loss, requiring a short-term energy deficit Successful weight control, requiring long-term Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 All opportunities for client education should stress healthy eating and physical activity. Nutritional therapy -Restricted food intake is a cornerstone. Discourage fad diets Drug Therapy Classified into two categories -↓ Food intake by reducing appetite or increasing satiety -↓ Nutrient absorption Nutrient absorption-blocking drugs They work by blocking fat breakdown and absorption in intestine. Undigested fat is excreted in the feces. Orlistat (Xenical) Collaborative Surgical Therapy Bariatric surgery is used to treat morbid obesity. Currently it is the only treatment found to have a successful and lasting impact for sustained weight loss. Stringent criteria for consideration for surgery Three categories: restrictive, malabsorptive, or a combination of both Selection Criteria for Bariatric Surgery? Must be 18 years old or older BMI > 35 kg/m2 and one or more comorbidities: hypertension; diabetes; cardiac disease; obstructive sleep apnea or BMI > 40 kg/m2 Multiple attempts to lose weight in a medically supervised program Surgical Management Procedure outcome: 1. Restrictions: decrease food intake 2. Malabsorption: interferes with ingested nutrition absorption 3. Hormonal changes: chemical signals thatcontrol hunger Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 Goal of surgery is to have an average weight loss of 61% of pre surgery weight One year from referral to surgery Follow-up appointments for 1 year post surgery Although not reversible – patient can still regain all weight if not following dietary recommendations SURGICAL INTERVENTIONS FOR MORBID OBESITY Restrictive Surgery: Adjustable gastric banding (AGB) Vertical sleeve gastrectomy Malabsorptive Surgery: Biliopancreatic diversion (BPD) with or without duodenal switch Combination of Restrictive and Malabsorptive Surgery: Roux-en-Y gastric bypass (RYGB) Gastric Banding Advantages: Adjustable}Reduces the size of the stomach(eat less; fewer calories; lose weight No stapling, cutting, or intestinal re-routing Least invasive surgical approach Lowest mortality and complication rate Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 Disadvantages: Initially, weight loss is slower compared to the gastric bypass procedures Weight loss is variable It is not an effective treatment for sweet-eaters Everyone requires multiple band adjustments Combination of Restrictive and Malabsorptive Surgery: LRYGB Considered to “golden standard” of obesity surgery Advantages: Has low complication rates Excellent client tolerance Stomach size is decreased with a gastric pouch anastomosis that empties directly into jejunum. Disadvantages: Some vitamin and mineral deficiencies can occur. Iron, calcium, Vit B12, and multivitamins. The bypassed portion of the stomach, duodenum, and segments of the small intestine cannot be easily visualized using X-ray or endoscopy if problems such as ulcers, bleeding or cancer should occur. This surgery is meant to be permanent. Cosmetic Surgeries to Reduce Fatty Tissue and Skin folds Ideal candidates have achieved weight reduction. excess skin folds or fat. Surgery for cosmetic reasons Lipectomy Liposuction Nursing Management: Obese Client Undergoing Surgery (Cont.) Nursing implementation (Cont.) Ambulatory and home care Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 Clients who have just had bariatric surgery have been unsuccessful in maintaining a prescribed diet in the past. reducing intake because of anatomical changes. The client must learn to adjust intake sufficiently with regard to nutrition and maintaining a stable weight. Diet Monitor for possible complications. Diet Postoperative diet: liquid diet In 2 months after surgery wll start on a solid foods 6 small feedings totaling 600 to 800 calories per day Eating more slowly, taking small size bites, chewing foods well, eating foods that are not dry or tough, and avoid high sugar food. Evaluation Outcomes Long-term weight loss Improvement in obesity-related comorbidities Integration of healthy practices into daily routine Monitoring possible adverse effects of surgical therapy Improved self-image Diabetes Classification of Diabetes Type 1 Type 2 Gestational Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 Type 1 and 2 TYPE 1- 10% of diabetics Inability to produce insulin, destruction of beta cells in pancreas Impaired ability to store glucose Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 Requires outside source of insulin Abrupt onset Onset any age but usually 35 but now in younger clients May be associated with other conditions (PCOS) Gestational Glucose intolerance with pregnancy, placental hormones increase insulin resistance Up to 3.8% of women affected Resolves with delivery but significantly higher risk for development of Type 2 Older age, hypertension Clinical Manifestations “Three Ps” o Polyuria o Polydipsia o Polyphagia Fatigue, vision changes, tingling or numbness in hands or feet, dry skin, skin lesions or prolong wound healing, and recurrent infections Type 1 may have sudden weight loss, nausea, vomiting, and abdominal pain if DKA has developed Diagnostic Tests Fasting blood glucose: >7.0 mmol/L (fasting 8 hrs) Random glucose: >11.1 mmol/L Hgb A1C: >6.5% Urine for ketones (type 1) and sugar Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 Treatment goal is to normalize blood glucose levels Nursing Assessment Health history Subjective & objective data NURSING DIAGONSES Ineffective self-health management r/t insufficient knowledge as evidenced by continued hyperglycemia Imbalanced nutrition: more than body requirements r/t intake in excess of activity expenditure by hyperglycemia or weight gain Risk of injury r/t decrease tactile sensation Risk for peripheral neurovascular dysfunction r/t vascular effects of diabetes Planning Overall goals: 1. To be active participant in the management of the DM regimen 2. To experience few or no episodes of hypoglycemia or acute hyperglycemic emergencies 3. To maintain blood glucose levels at normal or near-normal levels 4. To prevent, minimize, or delay the occurrence of chronic complication of DM 5. To adjust lifestyle to accommodate DM regimen with a minimum of stress Nutritional Therapy Consider food preferences, lifestyle, usual eating times, and cultural or ethnic background Review diet history and need for weight loss, gain, or maintenance Consider caloric requirements and calorie distribution throughout the day Carbohydrates: 50% to 60% carbohydrates, emphasize whole grains Fat: 20% to 30%, with >10% from saturated fat and >300 mg of cholesterol Protein: Contribute 15% to 20% of total energy consumed Fibre Provide exchange lists Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 Glycemix Index Describes how much a food increases blood glucose Recommendations: combining starchy food with protein- and fat-containing food slows absorption and glycemic response Raw or whole foods tend to have lower response than cooked, chopped, or pureed foods Eating whole fruits rather than juices decreases the glycemic response owing to fiber slowing absorption Adding food with sugars may produce lower response if eaten with foods that are more slowly absorbed Other Dietary Concerns Alcohol Nutritive and nonnutritive sweeteners Reading labels Role of the nurse Be knowledgeable about dietary management Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 Communicate important information to the dietitian or other management specialists Reinforce patient understanding Support dietary and lifestyle changes Exercise Lowers blood glucose levels ↑ insulin receptor sites Aids in weight loss Lowers cardiovascular risk Exercise Precautions Exercise when blood sugar levels are elevated (above 14 mmol/L) and ketones are present in urine should be avoided Insulin normally decreases with exercise; patients on exogenous insulin should eat a 15-g carbohydrate snack before moderate exercise to prevent hypoglycemia If exercising to control or reduce weight, insulin must be adjusted Potential exists for postexercise hypoglycemia Need to monitor blood glucose levels Exercise Recommendations Encourage regular daily exercise Gradual increase in exercise period is encouraged Modify exercise regimen to patient needs and presence of diabetic complications or potential cardiovascular problems Exercise stress test for patients older than age 30 who have two or more risk factors is recommended Gerontologic considerations Acute Complications of Diabetes Hypoglycemia Diabetic ketoacidosis (DKA) Hyperglycemic hyperosmolar nonketotic syndrome (HHNS), or hyperosmolar nonketotic coma, or hyperglycemia hyperosmolar syndrome (HHS) Hypoglycemia Downloaded by athraa emad ([email protected]) lOMoARcPSD|31047557 Abnormally low blood glucose level
