A client with cystic fibrosis (CF) is concerned about how this condition affects their body.
The client asks, "Why does CF lead to the production of thick mucus in the lungs and other organs?" Which of the following responses by the nurse is accurate?

"The CFTR gene mutation causes excessive water transport in the body.”

"CF results in an overproduction of a specific enzyme that thickens mucus.”

"The CFTR gene mutation impairs chloride and water transport in cells.”

"CF primarily affects the production of surfactant in the lungs.”

Answer and Explanation

The Correct Answer is C

"The CFTR gene mutation impairs chloride and water transport in cells.”.

Choice A rationale:

The CFTR gene mutation does not cause excessive water transport in the body.

In fact, CF leads to a defect in chloride and water transport in cells, which results in the production of thick mucus.

Choice B rationale:

CF does not result in an overproduction of a specific enzyme that thickens mucus.

Instead, it affects the functioning of the CFTR protein, which is responsible for maintaining the balance of chloride and water in cells.

Choice D rationale:

CF does not primarily affect the production of surfactant in the lungs.

Surfactant is a substance that helps prevent the collapse of alveoli in the lungs, and CF primarily affects the mucus and airway clearance, not surfactant production.

Correct Answer is ["A","B","D","E"]

Explanation

Choice A rationale:

Encouraging physical activity and exercise is important in managing CF.

It helps improve lung function and overall health in individuals with CF.

Choice B rationale:

Administering pancreatic enzyme replacement therapy is a crucial part of CF management.

CF often affects the pancreas, leading to malabsorption, and these enzymes help digest and absorb nutrients properly.

Choice C rationale:

Restricting fluid intake to reduce mucus production is not a recommended intervention for CF.

Hydration is essential to keep mucus from becoming too thick and sticky.

Dehydration can worsen mucus obstruction.

Choice D rationale:

Teaching airway clearance techniques is essential in CF management.

It helps individuals clear the thick mucus from their airways, promoting better lung function.

Choice E rationale:

Promoting a high-fat, high-calorie diet is important for individuals with CF.

CF often leads to malnutrition, and a high-calorie diet helps maintain proper nutrition and growth.

A. "Monitoring the child's blood sugar levels.” B. "Assessing the child's dental hygiene practices.” C. "Evaluating the child's lung sounds and respiratory rate.” D. "Observing for signs of gastrointestinal obstructions.”

Correct Answer is C

Explanation

Choice A rationale:

Monitoring the child's blood sugar levels is not relevant to a child with cystic fibrosis experiencing recurrent respiratory infections.

Cystic fibrosis primarily affects the respiratory and digestive systems, and blood sugar levels are not a significant concern in this context.

Choice B rationale:

Assessing the child's dental hygiene practices is important for overall health, but it is not the most relevant assessment in the case of a child with cystic fibrosis and recurrent respiratory infections.

The primary focus should be on the respiratory system.

Choice D rationale:

Observing for signs of gastrointestinal obstructions is an essential part of caring for a child with cystic fibrosis, but in the context of recurrent respiratory infections, evaluating lung sounds and respiratory rate is the most critical assessment.

Gastrointestinal issues are important but secondary to the respiratory concerns in this case.
