SECTION 1: Cystic Fibrosis Pathophysiology & Assessment
(Questions 1-12)
Q1: Christopher Parrish is a 15-year-old male with cystic fibrosis. His mother asks the
nurse to explain why her son has such thick, sticky mucus in his lungs. The nurse's
best response is based on understanding that CF is caused by:
A. An autoimmune response that attacks the cilia lining the respiratory tract
B. A mutation in the CFTR gene on chromosome 7 that results in defective chloride
ion transport and decreased water movement into airway surfaces [CORRECT]
C. A bacterial infection that permanently damages the mucus-producing glands
D. A deficiency in surfactant production that causes alveolar collapse
,Correct Answer: B
Rationale: Cystic fibrosis is an autosomal recessive disorder caused by mutations in
the CFTR (cystic fibrosis transmembrane conductance regulator) gene located on
chromosome 7. The defective CFTR protein impairs chloride ion transport across
epithelial cell membranes, leading to decreased water movement into the airway
surface liquid. This results in thick, dehydrated mucus that obstructs airways and
creates an environment favorable to chronic infection. Option A incorrectly describes
an autoimmune process. Option C describes a secondary complication, not the
primary cause. Option D describes respiratory distress syndrome, not CF.
Q2: During assessment, the nurse notes that Christopher has digital clubbing and a
barrel chest. These findings are most directly related to:
A. Chronic hypoxemia and air trapping from obstructed airways [CORRECT]
B. Acute respiratory acidosis from pneumonia
C. Side effects of long-term corticosteroid use
D. Malnutrition and vitamin A deficiency
Correct Answer: A
Rationale: Digital clubbing develops from chronic tissue hypoxia and is a hallmark of
chronic respiratory diseases like CF. The barrel chest results from chronic air trapping
due to mucus obstruction, inflammation, and airway remodeling. These are chronic
adaptations, not acute changes. Option B describes an acute process that wouldn't
cause these chronic structural changes. Option C might cause other side effects but
not clubbing or barrel chest. Option D causes different manifestations (night
blindness, poor wound healing).
Q3: The nurse is reviewing Christopher's genetic testing results. His parents are both
carriers of the ΔF508 mutation. The nurse correctly explains that:
A. Each child they have has a 50% chance of having CF
, B. Each child they have has a 25% chance of having CF [CORRECT]
C. Christopher's siblings cannot be carriers if they don't have symptoms
D. Only males can inherit CF because the gene is on the Y chromosome
Correct Answer: B
Rationale: CF is autosomal recessive. When both parents are carriers (heterozygous),
each child has a 25% chance of being affected (homozygous), a 50% chance of being
a carrier (heterozygous), and a 25% chance of being unaffected (homozygous
normal). Option A confuses carrier probability with affected probability. Option C is
incorrect—carriers are asymptomatic. Option D is false—CF affects both sexes
equally as it's autosomal, not sex-linked.
Q4: The nurse assesses Christopher's respiratory status and notes coarse crackles
throughout all lung fields, a productive cough with thick green-tinged sputum, and
decreased breath sounds at the right base. These findings indicate:
A. Resolution of a previous pneumonia
B. Chronic airway obstruction with probable Pseudomonas aeruginosa colonization
[CORRECT]
C. Acute pneumothorax requiring chest tube insertion
D. Normal findings for a teenager with mild asthma
Correct Answer: B
Rationale: Coarse crackles, productive cough with thick mucus, and decreased
breath sounds are classic for CF-related chronic airway obstruction. Green-tinged
sputum suggests Pseudomonas aeruginosa colonization, which occurs in
approximately 80% of adults with CF. These are chronic, not resolving, findings.
Option A is incorrect—resolution would show improving, not persistent, findings.
Option C would present with sudden dyspnea, absent breath sounds, and
hyperresonance. Option D minimizes serious pathology.
