What is the most appropriate diagnosis for a 7-year-old boy with recurrent motor movements?

Correct Answer: C

Rationale: The most appropriate diagnosis for a 7-year-old boy with recurrent motor movements is C) Persistent Tic Disorder. This is the correct answer because Persistent Tic Disorder is characterized by the presence of one or more motor tics and/or vocal tics that have been present for more than a year. In children, motor tics are commonly seen as sudden, rapid, recurrent, non-rhythmic movements of specific muscle groups. Option A) Tourette's Disorder is incorrect because Tourette's Disorder involves the presence of both motor and vocal tics for at least a year. Since the scenario only mentions motor movements, Tourette's Disorder is not the most appropriate diagnosis. Option B) Provisional Tic Disorder is incorrect because this diagnosis is used when the tics have been present for less than a year. In the case of the 7-year-old boy with recurrent motor movements, the duration of symptoms is longer, making Provisional Tic Disorder less likely. Option D) Sydenham Chorea is incorrect as it is a neurological disorder characterized by rapid, uncoordinated jerking movements affecting primarily the face, hands, and feet. This condition is associated with rheumatic fever and usually occurs in the context of recent streptococcal infection, which is not mentioned in the scenario. Educationally, understanding the differences between these diagnoses is crucial for healthcare providers, especially pediatric clinical nurse specialists, when assessing and managing children with movement disorders. Recognizing the specific criteria for each disorder helps in making accurate diagnoses and developing appropriate treatment plans to support the child's health and well-being.

Correct Answer: C

Rationale: The correct answer is C) 18 and 24 months for screening children for autistic spectrum disorders. This timing aligns with the American Academy of Pediatrics' recommendations for autism screening at the 18 and 24-month well-child visits. Screening at these specific ages allows for early identification and intervention, which can significantly impact a child's long-term outcomes. Option A) 6 and 12 months is too early for accurate autism screening as many developmental milestones are still expected to be achieved within this timeframe, making it difficult to differentiate typical development from potential signs of autism. Option B) 12 and 18 months is also too early for reliable autism screening as many behaviors associated with autism may not be fully evident at these ages, leading to potential under-identification of children who may benefit from early intervention. Option D) 24 and 30 months is too late for optimal autism screening as early intervention is crucial for improving outcomes for children with autism. Waiting until 24 months may delay access to critical services and support that could positively impact a child's development. Educationally, understanding the recommended ages for autism screening is essential for healthcare providers working with children and families. Early detection and intervention can lead to improved outcomes for children with autism spectrum disorders, underscoring the importance of timely and accurate screening practices.

Correct Answer: D

Rationale: In pica disorder, the most appropriate statement is that it needs a period of more than a month to be stated (Option D). This is because pica disorder is characterized by the persistent eating of non-nutritive, non-food substances over a period of at least one month. This behavior is considered developmentally inappropriate and not part of culturally supported or socially normative practices. Option A is incorrect because pica disorder is not limited to eating clay and earth; individuals with pica may consume a wide range of non-food items. Option B is incorrect because pica disorder can occur in individuals of any age, not just in children below 2 years. It is more commonly observed in children, but it can also affect adolescents and adults. Option C is incorrect because pica disorder can coexist with other eating disorders such as anorexia nervosa or bulimia nervosa. It is important to assess for and differentiate pica from other eating disorders to provide appropriate interventions. Educationally, understanding pica disorder is crucial for healthcare providers, especially pediatric clinical nurse specialists, as they play a key role in assessing, diagnosing, and managing pediatric patients with various disorders. Recognizing the signs and symptoms of pica disorder can lead to early intervention and appropriate treatment to prevent potential complications associated with ingesting non-food substances.

Correct Answer: C

Rationale: In this scenario, option C is the correct answer because interfering early by trying to calm the child can inadvertently reinforce the behavior, making it more likely to occur in the future. It is important to avoid reinforcing behaviors that may be undesirable or unnecessary. Option A is incorrect because a brief tonic movement after being upset and crying is not necessarily indicative of iron deficiency anemia in an 18-month-old child. It is important to consider a broader range of possible causes before jumping to conclusions. Option B is incorrect because avoiding over-concerned behavior can help prevent unnecessary stress and anxiety in both the parent and the child. It is important for parents to remain calm and rational in order to provide the best care for their child. Option D is incorrect because behaving calmly is a key aspect of effective parenting and caregiving. Remaining calm can help de-escalate situations and provide a sense of security for the child. In an educational context, it is crucial for healthcare providers to educate parents on appropriate responses to their child's behavior and provide evidence-based advice to promote the child's well-being. Understanding child development and behavior can help parents navigate challenging situations with confidence and effectiveness.

Correct Answer: B

Rationale: The correct answer is B) increase brain size. In pediatric patients with autistic spectrum disorders (ASD), structural MRI brain findings often show an increased brain size, particularly in early childhood. This phenomenon is known as macrocephaly and is one of the consistent features seen in individuals with ASD. This structural abnormality is thought to be related to abnormal brain development and enlargement of certain brain regions. Option A) diffuse brain atrophy is incorrect because ASD is not typically associated with widespread brain shrinkage. Option C) focal fibrosis and option D) white matter degenerative changes are also incorrect as they are not commonly observed structural MRI findings in individuals with ASD. Educationally, understanding the structural MRI findings associated with ASD is crucial for healthcare professionals, especially pediatric clinical nurse specialists, who work with children diagnosed with ASD. Recognizing these patterns can aid in early diagnosis, treatment planning, and providing appropriate care and support to children and their families. Keeping abreast of the latest research findings in this area is essential for providing evidence-based care to children with ASD.
