Final answer:
The instruction indicating that parents need more education on cystic fibrosis care is 'She takes antibiotics only when she feels very unwell,' as proactive antibiotic use is critical in managing CF complications.
Step-by-step explanation:
The instruction that indicates the parents need more instruction about the respiratory care of the child with CF complications is option d) "She takes antibiotics only when she feels very unwell." This statement is concerning because those with CF require proactive use of antibiotics to fight off infections, not just when symptoms are severe. The excess mucus in CF can lead to frequent lung infections and requires a more vigilant approach to antibiotic therapy. It is essential to adhere to a prescribed antibiotic regimen to manage infections effectively and prevent further lung damage.
By contrast, using an inhaler as prescribed (a), undergoing airway clearance techniques twice a day (b), and ensuring adequate outdoor activities (c), when possible, are all part of a comprehensive CF care plan. While limiting outdoor activities may be interpreted as overly cautious, it is important that the child is protected from exposure to pathogens and pollutants that could worsen their condition. However, the statement about antibiotics displays a fundamental misunderstanding of the maintenance and treatment necessary for managing CF complications.
