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 C

Explanation

Choice A rationale:

"I have difficulty breathing when I'm playing outside.”.

This statement may be relevant to a respiratory assessment in a child with CF but does not address the typical gastrointestinal symptoms associated with the condition, such as greasy stools.

Choice B rationale:

"My fingers and toes look round and wide.”.

This statement is not related to the typical symptoms of CF.

The characteristic physical findings in CF are often related to respiratory and gastrointestinal issues rather than finger and toe appearance.

Choice C rationale:

"My stools are greasy and float in the toilet.”.

This statement is an accurate description of one of the common gastrointestinal symptoms of CF.

CF can lead to malabsorption of fats, resulting in greasy, foul-smelling stools that float in the toilet due to their high fat content.

Choice D rationale:

"I often have trouble controlling my blood sugar.”.

This statement is not typically associated with CF.

Blood sugar control issues are more commonly linked to conditions like diabetes, not CF, which primarily affects the respiratory and gastrointestinal systems.

A. "Encourage frequent handwashing to reduce the risk of infections.” B. "It's unnecessary to worry about hand hygiene in this case.” C. "Have your child interact closely with friends and classmates to build immunity.” D. "Avoid vaccinations, as they can exacerbate cystic fibrosis symptoms.”

Correct Answer is A

Explanation

Choice B rationale:

Stating that hand hygiene is unnecessary in this case is incorrect.

Hand hygiene is crucial in infection control, especially for individuals with cystic fibrosis who may be more susceptible to infections due to compromised lung function.

Encouraging frequent handwashing is a key preventive measure.

Choice C rationale:

Having a child interact closely with friends and classmates to build immunity is not a recommended strategy for infection control in a child with cystic fibrosis.

Close contact with others can increase the risk of exposure to respiratory infections, which should be minimized.

Choice D rationale:

Avoiding vaccinations is not advisable, as vaccinations are an essential part of preventing various infectious diseases.

While certain vaccinations may need to be discussed with the healthcare provider to account for the child's individual health status, it is generally not recommended to avoid vaccinations as they can help prevent illness.
