Correct Answer: D

Rationale: The correct answer is D, Rheumatic fever. Rheumatic fever can develop as a complication of untreated strep throat caused by beta-hemolytic streptococcus. It is characterized by inflamed joints and can lead to serious complications such as heart infections. Tetanus (choice A) is caused by a bacterial toxin affecting the nervous system, Influenza (choice B) is a viral respiratory illness, and Scarlet fever (choice C) is also caused by streptococcus but is characterized by a sandpaper-like rash and strawberry tongue. However, in the scenario described, the nurse is most concerned about the child developing rheumatic fever due to the potential serious consequences associated with it.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid gluten.' Children with celiac disease must follow a gluten-free diet to prevent symptoms and intestinal damage. Gluten is a protein found in wheat, barley, and rye, which triggers an immune response in individuals with celiac disease. Choices A, C, and D are incorrect because while some individuals with celiac disease may also have lactose intolerance or may need to manage fat or sugar intake for overall health, the primary dietary restriction for celiac disease is avoiding gluten to maintain gastrointestinal health.

Correct Answer: D

Rationale: Recognizing signs of hypoglycemia is crucial for managing type 1 diabetes mellitus and preventing complications.

Correct Answer: B

Rationale: Assessing the child's dietary intake is crucial for managing asthma symptoms as certain foods can trigger or worsen asthma attacks. Monitoring dietary intake helps ensure the child receives proper nutrition and avoids triggers. Assessing sleep patterns (Choice A) may be relevant but not as directly impactful on asthma management. Academic performance (Choice C) and behavior at home (Choice D) are important aspects of a child's overall health but are not as directly related to asthma management as dietary intake.

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.
