1. Which pediatric condition is most likely to present with a "whooping" sound during coughing?

• A. Croup
• B. Bronchitis
• C. Pertussis
• D. Asthma

Correct answer: C

Rationale: The correct answer is C: Pertussis. Pertussis, also known as whooping cough, is characterized by a "whooping" sound during coughing episodes. This distinctive sound is due to the rapid intake of air after a series of coughs. Choice A, Croup, typically presents with a barking cough and stridor. Choice B, Bronchitis, is characterized by a productive cough with mucus. Choice D, Asthma, usually presents with wheezing and shortness of breath.

2. Which factor is most likely to cause a "brittle" diabetic state in a child with type 1 diabetes?

• A. Noncompliance with diet
• B. Insulin resistance
• C. Frequent infections
• D. Hypothyroidism

Correct answer: C

Rationale: Frequent infections can destabilize blood sugar levels, leading to a "brittle" diabetic state in children with type 1 diabetes. Infections increase metabolic demands and can result in significant blood glucose fluctuations, requiring careful monitoring and adjustment of insulin therapy. Noncompliance with diet may affect blood sugar control but is not the primary cause of a "brittle" state. Insulin resistance is more common in type 2 diabetes rather than type 1. Hypothyroidism can impact metabolism but is not directly linked to the development of a "brittle" diabetic state in type 1 diabetes.

3. Which congenital heart defect causes a "boot-shaped" heart on a chest x-ray?

• A. Tetralogy of Fallot
• B. Coarctation of the aorta
• C. Transposition of the great arteries
• D. Ventricular septal defect

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot, a congenital heart defect with four distinct abnormalities, often presents with a "boot-shaped" heart on chest x-ray due to right ventricular hypertrophy. This characteristic finding is due to the specific combination of defects in this condition. Coarctation of the aorta (choice B), Transposition of the great arteries (choice C), and Ventricular septal defect (choice D) do not typically result in a "boot-shaped" heart on a chest x-ray like Tetralogy of Fallot does.

4. 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.

5. Which is described as an elevated, circumscribed skin lesion that is less than 1 cm in diameter and filled with serous fluid?

• A. Cyst
• B. Papule
• C. Pustule
• D. Vesicle

Correct answer: D

Rationale: A vesicle is an elevated, circumscribed lesion filled with serous fluid, typically less than 1 cm in diameter.
