Peds Test 2

Where do you auscultate baby lung sounds? Mid Axillary
Describe infant breathing patterns. Obligatory nose breathers and diaphragmatic breathers
How long is lung tissue growing? Until age 8
Describe respiratory tract of children 5 and under. Structures of respiratory tract have a narrower lumen making kids more susceptible to obstruction/distress from inflammation.
Why are children 5 and under more susceptible to respirtory obstruction/distress? Narrower lumen, even more narrow r/t inflammation
Most episodes of acute illness in young kids involve... respirtory systems d/t exposure to infection and decreased immunity.
Grunting indicates... chest pain. (Not "pain" they are reopening airsacks)
Respirtory physical assessment includes... Auscultation of the lung fields Palpatation (pain, tenderness?) Percussion (tissue density) Nasal flaring? (respirtory distress) Grunting (trying to reopen air sacks) Skin color clubbing cough?
Why palpate in respirtory assessment? Check for pain or tenderness
Why percuss in respirtory assessment? Assess tissue density.
Mottling Patchy red/white skin. Looks like webs on skin
Signs of respirtory distress? Mottling, pallor, cyanosis
Cough assessment... Type Progress Pattern Associated symptoms Secretions (odor color, consistency)
Clubbing Caused by proliferation of tisssue at the end of the fingers usually from hypoxia. Develops over time
Nasopharyngitis The common cold(usually viral). Treat symptoms.
Pharyngitis Painful inflamed throat. Usually viral. Treat symptoms. Warm salt water gargle. Antibiotics if bacterial. (strep a)

Asthma A CHRONIC INFLAMMATORY disorder of the airways (Reactive Airway Disease-RAD) Most common chronic disease of childhood. Symptoms can be controlled, doesnt go away.
Asthma. REVERSIBLE obstructive airway disease characterized by: Bronchoconstriction of smooth muscles. Inflammation and edema of bronchial mucosa. Increased mucus secretions.
Asthma. Exacerbation: Episodes of progressively worsening shorteness of breath, cough, wheezing, and/or chest tightness. Status asthmaticus is unrelenting, severe asthma that doesn't respond to tx, usually requiring ICU care.
Asthma. Immunologic Factors: Allergens that evoke the immune response. IgE mediates the hypersensitive reaction in the bronchial mucosa. Results in increased bd vessel permeability, contraction of smooth muscles, and stimulation of mucus secretions.
Asthma. Obstructive Symptoms: Inflammation and edema of mucous membranes. Accumulation of thick secretions. Spasm of the smooth muschle of bronchi and bronchioles decreaseing caliber of the bronchioles.
Asthma. Clinical Manifestations: Dyspnea, wheezing, and coughing. May feel itchy, uncomfortable, irritable, or restless. May c/o HA, feeling tired, or their chest feeling tight. Symptoms may be less obvious in infants. Infants may have retractions.
Asthma. Diagnosis: Clinical Manifestations. History (chronic cough w/o infection) Physical examination (wheezing?) Tests: Pulmonary Function Studies, Peak expiratory flow rate
Asthma. Pulmonary function: Based on personal best (or predicted for age). Green zone: 80-100%, great. asthma well controlled. Yellow zone: 50-80%, caution, may need to increase therapy. Red zone: <50%, medical alert! Give tx and call if not improved.
Asthma. Management: Allergen and trigger control to decrease exacerbations. Chest physiotherapy (CPT) like breathing exercises and physical training may help. Drug therapy to prevent and control asthma symptoms.
Asthma. Medication: Corticosteroids:most effective anti inflammatory. Give only short term or low dose. Aerosal ideal (Dec Systemic SE) NSAID-(Cromolyn Sodium). Prophylactic to inhibit release of histamine. Beta-Adrenergic Agonist: (Albuterol)Rescue med, no response-get he
Cystic Fibrosis (CF) Generated by genetics. An autosomal recessive disease characterized by altered function of the exocrine glands involving primarily the lungs, pancrease & sweat glands. Secretions-thick. Sweat &saliva-high lvls of sodium chloride.
Sweat Chloride Test Heat arm, test sweat.
First symptom of CF: Maconium illeus plugged up, so thick it wont pass. Not a good sign.
CF-Pancreatic involvement: 85% of CF kids have pancreatic involvement. -Obstruction of pancreatic ducts (eventual fibrosis) -Absence of enzymes causes malabsorption of fats and proteins.
CF-Respirtory involvement: 99.9% of CF kids have respirtory involvement. -Increased production of secretions causes airway obstruction.
CF effects on... Pacrease Respirtory Liver Reproductive(male infertility)
CF-Diet: Infant-Predigested formula (pregestimil) Kids-High cal, High Protein, Low or normal fat, plus fat soluble vitamins. Need supplemental pancreatic enzymes.
Aqudete (sp???) water soluble enzyme. Given before meal. Increase or decrease enzymes by consistency of poop.
CF-Management: Promote absorption. Maintain airway Prevent lung infection (TX WITH ABX) Assist child/family in adapting to a chronic disorder.
What pancreatic symptoms might you expect to find in an infant or child with CF? Poor Growth, failure to thrive; frequent, large foul smelling, foamy, fatty stools containing undigested food; protruding abdomen with atrophy of extremities and buttock; sx from deficiency of fat soluble vitamins (A, D, E, K); anemia
What respiratory symptoms might you see in CF pt? barrel chest, clubbing of nails, decreased exercise tolerance; frequent productive cough frequent pneumonia (may see atelectasis, inflitrations, emphysemic changes on x-ray; abnormal pulmonary function studies or ABG;s showing resp acidosis)
CF-Excessive sweating: May need salt pill. Losing too much Na+.
Tonsillectomy Post op no gargling, nose blowing, or coughing. Comfort measures, HOB up, WATCH FOR SIGNS OF HEMORRHAGE!
Nursing Care for Acute Epiglottitis (Supraglottitis) Constant vigilant observation and accurate assessment of respirtory status. -Facilitate resp efforts. -Promote rest/comfort. -Prevent Spread of Infection and complications. -Decrease temp. -Educate/Support family.
Chest Xray Provides a permanent record of the hearts size and configuration, its chambers and great vessels as well as the pattern of blood flow, esp in pulmonary vessels.
Fluroscopy Used mainly in conjunction with cardiac catheterization
Electrocardiogram (ECG) Measures electrical activity of heart and records it on graph paper
Echocardiography Involves the use of ultra high frequenc sound wave to produce an image of the hearts structure
Heart Cath Can give info on O2 sat, pressure changes in heart, cardiac output or stroke volume, anatomic abnormalities. Can sometimes be used to tx problems like valvular pulmonic stenosis and patent ductus arteriosus.
