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: A

Rationale: Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division that leads to the presence of an extra chromosome 21. This additional chromosome alters the normal genetic makeup, resulting in the characteristics associated with Down syndrome. Therefore, the correct answer is nondisjunction (Choice A). Choices B, C, and D are incorrect because Trisomy 21 is not caused by X-linked recessive inheritance, genomic imprinting, or autosomal dominant inheritance. Understanding the specific genetic mechanism involved in Trisomy 21 is crucial for grasping the basis of this chromosomal disorder.

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: Rolls over. At 6 months, most infants can roll over, increasing the risk of falls. It is important to emphasize to the parent the need for careful supervision to prevent accidents. While choices A, C, and D are also milestones in infant motor development, rolling over at this age poses a higher risk of accidents due to the increased mobility and potential for falls.

Correct Answer: C

Rationale: In this scenario, the nurse should consider that ineffective sucking and swallowing in a 2-week-old infant could be early signs of a heart defect such as a ventricular septal defect. This is crucial information as it can guide further assessment and management. Choice A is incorrect because while feeding problems can be common in neonates, in this case, the specific context of a suspected heart defect should be prioritized. Choice B is incorrect as inadequate sucking can indeed be significant, especially when considering potential underlying heart issues, regardless of the presence of cyanosis. Choice D is incorrect as while mucus retention can affect feeding, in this case, the focus should be on the possibility of a heart defect rather than a temporary issue like mucus interference.
