1. 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.

2. One of the major differences in clinical presentation between Crohn disease (CD) and ulcerative colitis (UC) is that UC is more likely to cause which clinical manifestation?

• A. Pain
• B. Rectal bleeding
• C. Perianal lesions
• D. Growth retardation

Correct answer: B

Rationale: Rectal bleeding is more commonly associated with ulcerative colitis (UC) than with Crohn disease (CD). While both conditions can cause abdominal pain and growth issues, bleeding is a hallmark of UC due to its superficial mucosal inflammation. Perianal lesions are more characteristic of CD, and growth retardation is typically not a direct clinical manifestation of either CD or UC.

3. A child is refusing to use the potty and having accidents, even though he has achieved toilet training. This is an example of which type of behavior?

• A. Positive reinforcement
• B. Desensitization
• C. Phobia
• D. Regression

Correct answer: D

Rationale: The correct answer is D, regression. Regression occurs when a child reverts to an earlier behavior, such as having accidents after being successfully toilet trained. This regression often happens due to stress or changes in routine. Choices A, B, and C are incorrect because positive reinforcement involves encouraging desired behavior, desensitization is a process of reducing sensitivity to a stimulus, and phobia is an intense fear or aversion to a specific object or situation, none of which directly apply to the described situation of the child having accidents after being toilet trained.

4. Which explains the importance of detecting strabismus in young children?

• A. Color vision deficit may result.
• B. Amblyopia, a type of blindness, may result.
• C. Epicanthal folds may develop in the affected eye
• D. Corneal light reflexes may fall symmetrically within each pupil

Correct answer: B

Rationale: Undetected strabismus can lead to amblyopia, where the brain favors one eye over the other, potentially resulting in permanent vision loss in the affected eye.

5. What is the best initial intervention for a child experiencing moderate dehydration?

• A. Administer IV fluids
• B. Encourage oral rehydration
• C. Monitor vital signs
• D. Provide clear fluids

Correct answer: B

Rationale: The correct answer is B: Encourage oral rehydration. Oral rehydration is the first-line treatment for moderate dehydration in children. It helps restore fluid balance and electrolyte levels. Administering IV fluids (Choice A) is usually reserved for severe cases of dehydration where oral rehydration is not feasible or ineffective. Monitoring vital signs (Choice C) is important but should not replace the immediate need for rehydration. Providing clear fluids (Choice D) may not contain the necessary electrolytes required for effective rehydration.
