Correct Answer: B

Rationale: The correct answer is to 'Avoid gluten.' Celiac disease is an autoimmune disorder triggered by the consumption of gluten, a protein found in wheat, barley, and rye. When individuals with celiac disease ingest gluten, it causes an immune response that attacks the lining of the small intestine. Therefore, avoiding gluten is crucial in managing celiac disease to prevent symptoms and intestinal damage. Choices A, C, and D are incorrect because they do not address the specific dietary restriction necessary for individuals with celiac disease. While some individuals with celiac disease may also have lactose intolerance (not dairy allergy) or may need to manage fat or sugar intake for other health reasons, the primary dietary focus for celiac disease is the strict avoidance of gluten-containing foods.

Correct Answer: D

Rationale: Recognizing signs of hypoglycemia is essential for managing type 1 diabetes mellitus. Hypoglycemia, which occurs when blood glucose levels drop too low, can be dangerous and requires immediate intervention to prevent severe complications. Monitoring blood glucose levels more frequently than once a day, following a strict meal plan, and administering insulin only when blood glucose is high are important aspects of diabetes management but recognizing signs of hypoglycemia is crucial as it enables prompt action to prevent adverse outcomes.

Correct Answer: B

Rationale: The correct answer is B: 'Toddlers are learning to assert independence, and this behavior is expected at this age.' At 18 months old, toddlers are in the stage of developing autonomy and testing boundaries. It is normal for them to exhibit behaviors such as temper tantrums and defiance as they explore their independence. Choice A is incorrect as discipline at this age is more about setting limits and providing guidance rather than preventing antisocial behaviors. Choice C is inappropriate as leaving a toddler alone in a crib after explaining unacceptable behavior is not a recommended approach for managing toddler behavior. Choice D is incorrect as the described behavior is typical of toddlers asserting independence, not related to the initiative stage of development. The best response involves acknowledging the child's developmental stage and understanding that these behaviors are part of their normal growth and development.

Correct Answer: D

Rationale: Correct answer: When feeding a newborn with choanal atresia, the nurse should anticipate that the infant may take only part of the feeding. This behavior is due to the condition causing difficulty in breathing through the nose while feeding, prompting the infant to pause for air. Choice A, 'Chokes on the feeding,' is incorrect as it does not specifically relate to the feeding behavior expected in choanal atresia. Choice B, 'Has difficulty swallowing,' is also incorrect because the issue in choanal atresia is primarily related to breathing rather than swallowing. Choice C, 'Does not appear to be hungry,' is not the typical behavior seen in infants with choanal atresia; they may still display hunger cues but struggle with feeding due to the condition.

Correct Answer: C

Rationale: In pyloric stenosis, a palpable olive-like mass in the abdomen is a classic finding. This mass is due to the hypertrophied pyloric muscle. Abdominal rigidity (choice A) is associated with conditions like peritonitis, substernal retraction (choice B) is typically seen in respiratory distress, and marked distention of the lower abdomen (choice D) is more characteristic of conditions like intestinal obstruction rather than pyloric stenosis.
