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 D

Explanation

A) Incorrect. The sweat chloride test is used for CF diagnosis, but it does not analyze genetic mutations.

B) Incorrect. Chest X-rays are used to assess lung changes but do not directly confirm CF by analyzing genetic mutations.

C) Incorrect. Pulmonary function tests assess lung function but do not confirm CF by analyzing genetic mutations.

D) Correct. Genetic testing is a diagnostic procedure commonly used to confirm CF by analyzing the specific CF gene mutations present in an individual.

A. "CF results from a dominant genetic mutation inherited from one parent." B. "CF occurs due to the presence of two dominant genetic mutations." C. "CF is caused by a recessive genetic mutation inherited from both parents." D. "CF is a non-genetic condition caused by environmental factors."

Correct Answer is C

Explanation

A) Incorrect. CF is an autosomal recessive genetic disorder, meaning that both copies of the CFTR gene must carry a mutation for the condition to manifest.

B) Incorrect. CF is not caused by dominant genetic mutations.

C) Correct. CF results from inheriting two recessive genetic mutations, one from each parent, leading to defective CFTR protein function.

D) Incorrect. CF is primarily a genetic disorder with well-established genetic mutations associated with its development.
