A nurse is discussing the clinical manifestations of cystic fibrosis (CF) with a newly diagnosed adolescent client. What common respiratory symptom should the nurse emphasize as an early sign of CF?

Wheezing and chest pain

Chronic cough with thick mucus production

Blood in the urine

Digestive discomfort and diarrhea

Answer and Explanation

The Correct Answer is B

A) Incorrect. Wheezing and chest pain can occur in CF, but a chronic cough with thick mucus production is often one of the earliest respiratory symptoms.

B) Correct. A chronic cough with thick, sticky mucus is a hallmark symptom of CF due to the accumulation of mucus in the respiratory tract.

C) Incorrect. Blood in the urine is not a common early sign of CF; it may indicate other issues.

D) Incorrect. Digestive discomfort and diarrhea are more related to CF's impact on the gastrointestinal system, rather than being early respiratory symptoms.

Correct Answer is B

Explanation

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.

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.
