Correct Answer:
"Chest physiotherapy helps break up thick secretions for ease of breathing."
Rationale:
Chest physiotherapy helps break up thick secretions for ease of breathing.
🟦Airway clearance techniques (percussion, vibration, postural drainage; or HFCWO vests) are cornerstone therapies in CF to mobilize viscous mucus caused by abnormal chloride transport.
🟦By reducing mucus plugging, they improve ventilation, decrease infection risk, and support gas exchange.
🟦Regular CPT—often multiple sessions daily—is paired with nebulized mucolytics (e.g., dornase alfa) and bronchodilators to enhance secretion mobilization.
🟦Consistent airway clearance reduces exacerbations and slows lung function decline, improving quality of life.
“Give pancreatic enzymes with or immediately before meals and snacks.”
🟦Pancreatic enzyme replacement therapy (PERT) corrects pancreatic insufficiency to enable fat, protein, and carbohydrate digestion.
🟦Administering with or just before every meal/snack ensures enzymes are present in the duodenum when food arrives, optimizing nutrient absorption.
🟦Proper dosing (based on lipase units/kg/meal) prevents steatorrhea, malabsorption, and poor growth.
🟦Enzymes should be swallowed intact (no crushing) to protect enteric coating and efficacy.
“Feed your child foods that are high in protein.”
🟦Children with CF have higher metabolic demands and malabsorption, so high-protein intake supports growth, tissue repair, and immune function.
🟦Adequate protein helps counter recurrent infections and increased work of breathing that elevate caloric expenditure.
🟦Combining high protein with PERT enhances nitrogen balance and lean body mass.
🟦Registered dietitian–guided plans ensure age-appropriate targets and sustained weight/height velocity.
“Give your child high-calorie foods and snacks.”
🟦CF nutrition plans emphasize calorie-dense intake (often 120–150% of standard energy needs) to achieve appropriate BMI percentiles.
🟦Frequent high-calorie snacks mitigate increased energy expenditure from chronic respiratory effort and infections.
🟦Calorie fortification (oils, powdered milk, nut butters) plus fat-soluble vitamins (A, D, E, K) supports growth and bone health.
🟦With PERT, higher calories—including dietary fats—are better absorbed, reducing failure to thrive.
