1. What is the most common cause of bronchiolitis in infants?

• A. Adenovirus
• B. Influenza virus
• C. Respiratory syncytial virus
• D. Parainfluenza virus

Correct answer: C

Rationale: The correct answer is C, Respiratory syncytial virus (RSV). RSV is the leading cause of bronchiolitis, a common respiratory condition in infants that results in inflammation of the small airways in the lung. It is highly contagious and can cause severe respiratory distress in young children, particularly those under 2 years old. Choice A, Adenovirus, is not the most common cause of bronchiolitis in infants. Choice B, Influenza virus, may cause respiratory infections but is not the primary cause of bronchiolitis. Choice D, Parainfluenza virus, can cause croup and other upper respiratory infections but is not the main cause of bronchiolitis in infants.

2. What is one focus of current health care?

• A. Increased provision of nursing services
• B. Disease prevention
• C. Symptom management
• D. Identification of disease processes

Correct answer: B

Rationale: The correct answer is 'Disease prevention.' Modern healthcare places emphasis on preventing diseases to enhance overall health and well-being. While nursing services, symptom management, and disease identification are crucial components of healthcare, disease prevention plays a key role in reducing the burden of illness on individuals and communities.

3. At what age is it safe to give infants whole milk instead of commercial infant formula?

• A. 6 months
• B. 9 months
• C. 12 months
• D. 18 months

Correct answer: C

Rationale: Whole milk should not be introduced before 12 months because it lacks the necessary nutrients, such as iron, that infants need for proper growth and development.

4. What dietary modification is recommended for a child with cystic fibrosis?

• A. High carbohydrate
• B. Low protein
• C. High calorie
• D. Low fat

Correct answer: C

Rationale: A high-calorie diet is recommended for children with cystic fibrosis due to their increased energy needs and malabsorption issues. Cystic fibrosis affects the pancreas, leading to poor digestion and absorption of nutrients, particularly fats, which requires dietary adjustments to maintain adequate nutrition. High carbohydrate (Choice A) is not the primary focus; the emphasis is on overall calorie intake. Low protein (Choice B) is not recommended as protein intake is essential for growth and development. Low fat (Choice D) is not the best option as fat-soluble vitamin absorption is already compromised in cystic fibrosis, hence fat restriction is not a priority.

5. What is the purpose of using cimetidine (Tagamet) for gastroesophageal reflux?

• A. The medication reduces gastric acid secretion.
• B. The medication neutralizes the acid in the stomach.
• C. The medication increases the rate of gastric emptying time.
• D. The medication coats the lining of the stomach and esophagus.

Correct answer: A

Rationale: The correct answer is A. Cimetidine (Tagamet) is an H2 receptor antagonist that works by reducing gastric acid secretion. This action helps to decrease the acidity in the stomach, which in turn reduces the symptoms of gastroesophageal reflux. Choice B is incorrect because cimetidine does not neutralize acid but rather decreases its production. Choice C is incorrect as cimetidine does not affect the rate of gastric emptying time. Choice D is incorrect as cimetidine does not coat the lining of the stomach and esophagus but instead works to reduce gastric acid secretion.
