Correct Answer: B

Rationale: Melena indicates bleeding from the upper GI tract. The black, tarry appearance of the stool results from the partial digestion of blood as it passes through the intestines, typically originating from sources like the stomach or duodenum. Lower GI bleeding usually presents as bright red blood in the stool, originating from sources like the colon or rectum. Choices A, C, and D are incorrect because melena specifically points to upper GI bleeding rather than issues in the perianal/rectal area, lower GI tract, or hemorrhoids/anal fissures.

Correct Answer: C

Rationale: Prolonged jaundice is a classic sign of congenital hypothyroidism in newborns. In congenital hypothyroidism, the thyroid gland does not produce enough thyroid hormones, leading to symptoms like jaundice, poor feeding, constipation, and lethargy. While jaundice itself is a common condition in newborns, the term 'prolonged jaundice' specifically points towards the underlying thyroid issue. Hypothermia and excessive crying are not typically associated with congenital hypothyroidism.

Correct Answer: A

Rationale: The correct answer is A: Strawberry tongue. In Kawasaki disease, a 'strawberry tongue' is most indicative of the acute phase. This refers to the tongue appearing red and swollen with enlarged fungiform papillae, giving it a strawberry-like appearance. Joint pain (Choice B) is more commonly associated with other conditions like rheumatoid arthritis. Rash (Choice C) and peeling skin (Choice D) are also seen in Kawasaki disease but are not as specific to the acute phase as the presence of a strawberry tongue.

Correct Answer: C

Rationale: Popcorn is a safe snack for a child with celiac disease as it is naturally gluten-free. Other options like pizza, pretzels, and oatmeal cookies typically contain gluten unless specifically made with gluten-free ingredients, which can exacerbate celiac symptoms. Therefore, popcorn is the best option to suggest to the child to avoid any adverse effects on their condition.

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.
