cystic fibrosis Flashcards
cystic fibrosis
- A respiratory disorder from inheriting a mutated gene.
- Characterized by mucus glands that secrete an increase in the quantity of thick, tenacious mucus, which leads to mechanical obstruction of organs:
pancreas, lungs, liver, small - Autonomic nervous system abnormalities.
what is increased
- An increase in organic and enzymatic constituents in the saliva
- An increase in the sodium and chloride content of sweat
risk factors
Both biological parents carry the recessive trait for cystic fibrosis.
Caucasian ethnicity
1/4
clinical findings
earliest indiction of CF
- Medical history of respiratory infections, growth failure
- Meconium ileus at birth manifested as distention of the abdomen, vomiting, and inability to pass stool.
- Meconium ileus is the earliest indication of cystic fibrosis in the newborn.
early manifestations respiraotry
- Wheezing, rhonchi
- Dry, nonproductive cough
- Increased involvement
- Dyspnea
- Paroxysmal cough
- Obstructive emphysema and atelectasis on chest x-ray
advanced symptoms
- Cyanosis
- Barrel-shaped chest
- Clubbing of fingers and toes
- Multiple episodes of bronchitis or bronchopneumonia
gastro findings
- Large, frothy, bulky, greasy, foul-smelling stools (steatorrhea)
- Voracious appetite (early)
- Loss of appetite (late)
- Failure to gain weight or weight loss
- Delayed growth patterns
- Distended abdomen
- Thin arms and legs
- Deficiency of fat-soluble vitamins
- Anemia
integumentary findings
Sweat, tears, and saliva have an excessively high content of sodium and chloride.
endocrine findings
- Viscous cervical mucus
- Decreased or absent sperm
blood specimen
Nutritional panel to detect a deficiency of fat-soluble vitamins (A, D, and E).
sputum culture
For detection of infection: Pseudomonas aeruginosa, Haemophilus influenzae, Burkholderia cepacia, Staphlococcus aureus, Escherichia coli, or Klebsiella pneumoniae
diagnsotic tests
- DNA testing: To isolate the mutation
- Pulmonary function tests (PFTs)
- Chest x-ray: Can indicate diffuse atelectasis and obstructive emphysema
- Abdominal x-ray: Detect meconium ileus
Stool analysis
- For presence of fat and enzymes
- 72 hr sample with documented food intake
sweat chloride test
- The child must be well hydrated.
- A device uses an electrical current to stimulate sweat production.
- Collection of sweat from two different sites for adequate sample
- Expected reference range is chloride content less than 40 mEq/L and sodium content less than 70 mEq/L.
sweat chloride numbers
Chloride greater than 40 mEq/L for infants less than 3 months of age
greater than 60 mEq/L for all others; sodium greater than 90 mEq/L
start nursing care
- Assess lung sounds and respiratory status.
- Vital signs with oxygen saturation.
- Obtain IV access.
- Use of a peripherally inserted central catheter allows for home IV antibiotic therapy.
- Obtain sputum for culture and sensitivity.
pulmonary management nursing care
- Airway clearance therapy (ACT)
- Usually prescribed twice a day in the morning and evening.
- Avoid ACT immediately before or after meals.
- Chest physiotherapy (CPT)
- Positive expiratory therapy (PEP)
- Active-cycle-of-breathing techniques, such as “huffing” or forced expiration, are encouraged.
- Autogenic drainage uses an electronic chest vibrator or handheld percussor along with breathing techniques.
High-frequency chest compression - uses a device, such as a flutter mucus clearance device, to encourage the client to breathe with forceful exhalations.
pulmonary management nursing care med admin
- Administer aerosol therapy as prescribed (bronchodilator, human deoxyribonuclease).
- Often recommended prior to ACT.
- Administer IV or aerosolized antibiotics.
- Encourage physical aerobic exercise.
- Provide oxygen as prescribed (assess for carbon dioxide retention).
gastro nursing care
- Give three meals a day with snacks.
- Encourage oral fluid intake.
- Administer pancreatic enzymes within 30 min of eating a meal or snack.
- Administer vitamin supplements.
- Administer laxatives or stool softeners for constipation.
- Administer histamine-receptor antagonist and motility medications for GERD.
- Administer possible formula supplements in addition to breast feedings or via gastric tube.
Consult a dietitian. - Provide a well-balanced diet high in protein and calories. Polyethylene-glycol electrolyte solution is administered orally or via nasogastric tube.
endocrine nursing care
- CF related diabetes (CFRD) necessitates monitoring of blood glucose levels.
- Administer insulin.
- Oral glycemic medications are not effective for CFRD.
short acting beta 2 agonists (abuterol)
- Cholinergic antagonists (anticholinergics)
- ipratropium bromide (dry mouth)
- Fluticasone propionate/salmeterol
- Monitor for tremors and tachycardia
Dornase alfa - Decreases the viscosity of mucus and improves lung function
- Monitor sputum thickness and ability of client to expectorate.
- Monitor the child for improvement in PFTs.
- Instruct the child how to use a nebulizer.
- Instruct the child to administer once or twice a day.
antibiotics
- Administer through IV or aerosol.
-Specific to treat pulmonary infection.
-Common medications include tobramycin, ticarcillin,
or gentamicin.
-Assess for allergies.
-High doses may be prescribed.
-Collect blood specimens before and after some IV antibiotics to maintain therapeutic levels.
pancreatic enzymes: pancrelipase
- Monitor stools (1 to 2 stools/day).
- Administer capsules with all meals and snacks.
- Client can swallow or sprinkle capsules on food.
- Increase dosage of enzymes when eating high-fat foods.
vitamins
Daily multivitamin and vitamins A, E, D, and K
interprofessional care
- Respiratory and physical therapy
- Social services
- Pulmonologist
- Pharmacist
- Pediatrician
- Infectious disease specialists
- Dietitians
- Transplantation of heart, lung, pancreas, and liver for clients who have advanced disease can be a consideration.
education
- Ensure family has information regarding access to medical equipment and medications.
- Provide teaching about equipment and medications prior to discharge.
- Instruct the family about ways to provide CPT and breathing exercises.
- Promote regular provider visits.
- Emphasize the need for up-to-date immunizations and a yearly influenza vaccine.
- Teach about diet and ways to increase calorie intake.
- Teach indications of infection and when to call the provider.
education
- Teach parents about ways to manage chronic illness in children.
- Promote regular physical activity.
- Encourage the family to participate in a support group and use community resources.
- Identify specific needs based on the client’s developmental level.
- Provide home palliative care for the child or adolescent in the terminal stages of CF.
