Final answer:
The mother's statement that would best support a diagnosis of cystic fibrosis would typically include symptoms like frequent lung infections or the child tasting very salty, a sign of CF's characteristic salty sweat. However, no such statement is explicitly provided.
Step-by-step explanation:
The statement by the mother which supports the diagnosis of cystic fibrosis (CF) is not explicitly given in the scenarios provided. CF is an autosomal recessive genetic disease characterized by the production of thick, sticky mucus that can clog respiratory and digestive organs. This results in symptoms such as persistent cough with thick mucus, frequent lung infections, and trouble gaining weight. Of the available choices in the question:
- (A) 'She has frequent stomach aches.' - This can be associated with CF but is not specific.
- (B) 'Her father also had breathing problems.' - CF is genetic, but this doesn't confirm her father was a carrier.
- (C) 'She doesn't like the taste of salty foods.' - Unrelated to CF.
- (D) 'Her weight has been increasing steadily.' - Contrary to typical CF symptoms of difficulty gaining weight.
The most supportive mother's statement for a CF diagnosis would mention signs such as her child tasting very salty when kissed or struggling with persistent coughs and lung infections.
