Go to Quiz Page

Which gene mutation is primarily responsible for cystic fibrosis?

CFTR gene

Explanation

Mutation in CFTR gene leads to dysfunctional chloride channels.

What is the most common symptom of cystic fibrosis?

Salty-tasting skin

Explanation

Due to high salt concentration in sweat.

What is the mode of inheritance of cystic fibrosis?

Autosomal recessive

Explanation

Both parents must carry the faulty gene.

Which diagnostic test is commonly used to confirm cystic fibrosis?

Sweat chloride test

Explanation

Elevated chloride levels indicate the presence of cystic fibrosis.

What is the average life expectancy for individuals with cystic fibrosis?

40-50 years

Explanation

Advancements in treatment have increased life expectancy.

What is the main cause of pancreatic insufficiency in cystic fibrosis?

Obstruction of pancreatic ducts by mucus

Explanation

Mucus blocks pancreatic enzymes from reaching the intestines.

Which of the following is NOT a potential complication of cystic fibrosis?

Type 1 diabetes

Explanation

CF is not directly linked to Type 1 diabetes.

Which of the following is a treatment option for cystic fibrosis?

Bronchodilator medications

Explanation

Helps to widen airways and ease breathing.

Which of the following is NOT a characteristic feature of cystic fibrosis?

Hypertension

Explanation

Hypertension is not typically associated with CF.

#10

Which of the following is a common respiratory manifestation of cystic fibrosis?

Bronchiectasis

Explanation

Dilation and scarring of bronchial tubes.

#11

Which of the following is a potential gastrointestinal complication of cystic fibrosis?

Malabsorption

Explanation

Inadequate absorption of nutrients.

#12

Which ethnic group has the highest incidence of cystic fibrosis?

Caucasians

Explanation

Most common among people of European descent.

#13

What is the primary cause of death in individuals with cystic fibrosis?

Respiratory failure

Explanation

Due to lung complications.

#14

What is the hallmark respiratory manifestation of cystic fibrosis?

Chronic obstructive pulmonary disease (COPD)

Explanation

Characterized by airflow limitation.

#15

Which of the following is a potential complication of cystic fibrosis-related diabetes?

Hypoglycemia

Explanation

Opposite of high blood sugar levels.

#16

What is the role of the CFTR protein in the body?

Regulates sodium absorption

Explanation

Helps maintain proper salt balance.

#17

Which of the following is a common respiratory complication of cystic fibrosis in infants?

Meconium ileus

Explanation

Obstruction of the intestine at birth.

#18

Which organ systems are primarily affected by cystic fibrosis?

Respiratory and gastrointestinal systems

Explanation

CF affects primarily the lungs and digestive system.

#19

How does cystic fibrosis affect fertility in males?

Blocks the vas deferens

Explanation

Caused by thickening of seminal fluid.

#20

What is the gold standard method for diagnosing cystic fibrosis?

Genetic testing

Explanation

Identifies specific mutations in CFTR gene.

#21

What is the primary defect in cystic fibrosis?

Defective mucus production

Explanation

Results in thick, sticky mucus.

#22

Which of the following organs is NOT affected by cystic fibrosis?

Kidneys

Explanation

Kidneys are not typically affected.

#23

Which of the following is NOT a symptom of cystic fibrosis-related liver disease?

Frequent urination

Explanation

Frequent urination is not a common symptom.

#24

How does cystic fibrosis affect the viscosity of mucus?

Increases mucus viscosity

Explanation

Thicker mucus leads to airway blockage.

#25

What is the recommended treatment for meconium ileus in newborns with cystic fibrosis?

Surgical intervention

Explanation

To remove the blockage.
