A nurse is counseling a couple planning to start a family, and both partners have a family history of cystic fibrosis (CF). What should the nurse advise the couple regarding the genetic risk of having a child with CF?

"You both have a family history of CF, so it is impossible for your child to inherit the condition."

"Since you both carry a single CF gene mutation, your child has a 100% chance of developing CF."

"Your child will inherit CF only if both of you pass on a copy of the CF gene mutation."

"The risk of your child having CF is solely determined by the mother's genetic history."

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is B

Explanation

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.

A. Initiation of long-term oxygen therapy B. Administration of bronchodilators and corticosteroids C. Surgical lung transplantation D. Recommending bed rest and minimal physical activity

Correct Answer is B

Explanation

A) Incorrect. Long-term oxygen therapy is typically reserved for individuals with chronic hypoxemia and is not the primary treatment for a pulmonary exacerbation.

B) Correct. Bronchodilators and corticosteroids are commonly used to manage pulmonary exacerbations in CF by reducing airway inflammation and improving airflow.

C) Incorrect. Surgical lung transplantation is considered in severe cases of CF with irreversible lung damage but is not typically the first-line treatment for a pulmonary exacerbation.

D) Incorrect. Bed rest and minimal physical activity are not recommended as the primary treatment for pulmonary exacerbations; maintaining mobility and airway clearance techniques are important.
