A client with cystic fibrosis (CF) asks the nurse about the impact of CF on the respiratory system. What response by the nurse accurately describes the respiratory complications associated with CF?

"CF primarily affects the upper respiratory tract, leading to frequent sinus infections."

"CF causes inflammation and obstruction of the airways, leading to chronic lung infections and lung damage."

"CF typically results in enlarged tonsils and adenoids, which can affect breathing."

"CF mainly affects the bronchial tubes, causing chronic cough but not lung infections."

Answer and Explanation

The Correct Answer is B

A) Incorrect. CF primarily affects the lower respiratory tract, particularly the bronchi and bronchioles, rather than the upper respiratory tract.

B) Correct. CF leads to thickened mucus in the airways, which can cause inflammation, recurrent infections, and progressive lung damage.

C) Incorrect. Enlarged tonsils and adenoids are not a typical manifestation of CF-related respiratory complications.

D) Incorrect. CF affects both the bronchial tubes and the entire respiratory system, often leading to chronic lung infections.

Correct Answer is D

Explanation

A) Incorrect. Hypertension is not typically associated with CF.

B) Incorrect. Hypoglycemia is not a common manifestation of CF.

C) Incorrect. Chronic diarrhea is not a common symptom of CF.

D) Correct. CF is characterized by thick, sticky mucus that can lead to chronic respiratory infections, making this a key clinical manifestation to monitor.

A. "You both have a family history of CF, so it is impossible for your child to inherit the condition." B. "Since you both carry a single CF gene mutation, your child has a 100% chance of developing CF." C. "Your child will inherit CF only if both of you pass on a copy of the CF gene mutation." D. "The risk of your child having CF is solely determined by the mother's genetic history."

Correct Answer is C

Explanation

A) Incorrect. Both partners having a family history of CF increases the likelihood of carrying CF gene mutations, making it possible for their child to inherit the condition.

B) Incorrect. Having a single CF gene mutation (carrier status) does not guarantee that a child will develop CF; it requires inheriting two CF gene mutations, one from each parent.

C) Correct. CF is an autosomal recessive genetic disorder, which means that a child will have CF only if they inherit two copies of the CF gene mutation, one from each parent.

D) Incorrect. The risk of a child having CF is determined by both parents' genetic history, not solely the mother's.
