A
  • 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.

Q

diagnsotic tests

A
  • DNA testing: To isolate the mutation

Q

sweat chloride test

A
  • 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.

Q

start nursing care

A
  • Assess lung sounds and respiratory status.
  • Vital signs with oxygen saturation.

Q

pulmonary management nursing care

A
  • 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.
17
Q

pulmonary management nursing care med admin

A
  • 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).
18
Q

gastro nursing care

A
  • 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.
19
Q

endocrine nursing care

A
  • CF related diabetes (CFRD) necessitates monitoring of blood glucose levels.
  • Administer insulin.
  • Oral glycemic medications are not effective for CFRD.
20
Q

short acting beta 2 agonists (abuterol)

A
  • 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.
21
Q

antibiotics

A
  • 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.
22
Q

pancreatic enzymes: pancrelipase

A
  • 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.
