Ivytech Community college Lawrence campus paediatric exam ( 38 Questions)
The student nurse is collecting data on a child diagnosed with cystic fibrosis and notes the child has a barrel chest and clubbing of the fingers. In explaining this manifestation of the disease, the staff nurse explains the cause of this symptom to be:
High sodium chloride concentration in the sweat:Cystic fibrosis is characterized by abnormally thick and sticky mucus in various organs, including the respiratory and digestive systems. However, high sodium chloride concentration in the sweat is a diagnostic feature of cystic fibrosis. This doesn't directly explain the barrel chest and clubbing of the fingers.
Chronic lack of oxygen:Chronic lack of oxygen (chronic hypoxia) is more directly related to the development of clubbing of the fingers and certain respiratory symptoms. In conditions like cystic fibrosis, impaired lung function can lead to inadequate oxygenation, contributing to this manifestation.
Decreased respiratory capacity:
This is the correct explanation. Decreased respiratory capacity, often due to the chronic respiratory issues associated with cystic fibrosis, can result in a barrel chest (increased chest diameter due to air trapping) and clubbing of the fingers (a sign of chronic hypoxia).
Impaired digestive activity:While impaired digestive activity is another characteristic of cystic fibrosis, it is not directly linked to the barrel chest or clubbing of the fingers. Digestive issues in cystic fibrosis are primarily related to the thickening of mucus in the pancreas, leading to difficulties in digesting and absorbing nutrients.
A. High sodium chloride concentration in the sweat:
Cystic fibrosis is characterized by abnormally thick and sticky mucus in various organs, including the respiratory and digestive systems. However, high sodium chloride concentration in the sweat is a diagnostic feature of cystic fibrosis. This doesn't directly explain the barrel chest and clubbing of the fingers.
B. Chronic lack of oxygen:
Chronic lack of oxygen (chronic hypoxia) is more directly related to the development of clubbing of the fingers and certain respiratory symptoms. In conditions like cystic fibrosis, impaired lung function can lead to inadequate oxygenation, contributing to this manifestation.
C. Decreased respiratory capacity:
