Core Nursing Explanation
Key Concept Analysis: This question assesses the nurse's ability to recognize the core diagnostic criteria for
Intellectual Disability (ID) in a pediatric developmental assessment. ID is characterized by significant deficits in
intellectual functioning (e.g., reasoning, problem-solving) and
adaptive behavior (conceptual, social, and practical skills). The diagnosis requires that these limitations manifest during the
developmental period (before age 18). A 5-year-old is expected to have developed complex language skills, including multi-word sentences and basic conversational ability.
Answer Rationale:
Key Point! Option ② is correct because it directly points to a severe deficit in
adaptive behavior, specifically in the
conceptual domain (language). A typical 5-year-old should be speaking in complete, complex sentences, telling stories, and using a large vocabulary. Communicating primarily through single words and gestures is more consistent with the language level of a much younger toddler (around 18-24 months). This significant delay, especially when combined with deficits in intellectual functioning, is a hallmark indicator of ID.
Distractor Analysis:
Watch out for confusion! Option ① describes a mixed skill profile. The inability to tie shoelaces is common for a 5-year-old (fine motor skill still developing), while riding a bike with training wheels is an age-appropriate gross motor skill. This does not indicate a global deficit.
Option ③ describes a social preference (solitary play). While social skills can be affected in ID, preferring to play alone is also common in children with
Autism Spectrum Disorder (ASD) or can be a normal temperamental variation. It is not a definitive sign of ID on its own.
Option ④ describes behaviors consistent with
Attention-Deficit/Hyperactivity Disorder (ADHD), such as inattention and distractibility. While ADHD and ID can co-occur, hyperactivity and distractibility are not core diagnostic criteria for intellectual disability.
Related Concepts: Developmental assessment uses standardized tools (e.g., Denver II) to screen for delays. A formal diagnosis of ID involves psychological testing (IQ
< 70) and assessment of adaptive functioning. Nursing care focuses on supporting the child's strengths, facilitating communication, promoting independence in self-care, and providing family education and resources.
Concept Summary
| Concept | Key Points |
|---|
| Intellectual Disability (ID) | Deficits in intellectual & adaptive functioning originating in developmental period. |
| Adaptive Behavior Domains | Conceptual (language, academics), Social (empathy, relationships), Practical (self-care, routines). |
| Developmental Milestone: Age 5 | Speaks in full sentences, tells stories, dresses/undresses, hops on one foot. |
| Nursing Role | Developmental screening, family support, care coordination, promoting optimal functioning. |
Side-by-Side Comparison!
| Condition | Core Feature | Developmental Presentation (Age 5 Example) |
|---|
| Intellectual Disability (ID) | Global delays in cognitive & adaptive skills. | Uses single words/gestures; cannot follow simple 2-step commands. |
| Autism Spectrum Disorder (ASD) | Deficits in social communication & restricted/repetitive behaviors. | May have advanced vocabulary but lacks social reciprocity; engages in stereotyped play. |
| Attention-Deficit/Hyperactivity Disorder (ADHD) | Persistent inattention and/or hyperactivity-impulsivity. | Cannot sit still, easily distracted, but language and cognitive skills are age-appropriate. |
| Specific Learning Disorder | Difficulty in a specific academic area (e.g., reading, math). | Struggles with pre-reading skills but has normal conversational language and social skills. |
Anatomy, Physiology & Pharmacology Points
While ID is a neurodevelopmental disorder, understanding related physiology is key. It often involves atypical brain development affecting the
cerebral cortex and neural connectivity. Causes can be prenatal (e.g., Down syndrome, fetal alcohol syndrome), perinatal (birth asphyxia), or postnatal (severe head injury). There is no medication to treat ID itself, but pharmacotherapy may be used to manage co-occurring conditions like ADHD, seizures, or mood disorders.
Memory Tips
ID = "I Delay": Think of
Intellectual and
Daptive delays. For a 5-year-old, remember the "5 S's" they should be able to do:
Speak in sentences,
Skip,
Swing,
Stay dressed, and follow
Simple rules in games. Missing multiple "S's," especially speech, is a red flag.
High-Frequency NCLEX Topics
The NCLEX frequently tests the nurse's ability to differentiate between normal developmental variations and signs of a true disorder. You must know age-expected milestones. Questions often present a child's behavior and ask you to identify the most concerning finding or the priority nursing action (e.g., "Which finding should be reported to the primary care provider?").
Watch Out for Question Variations!
*
Symptom Identification → Priority Intervention: "The nurse notes a 5-year-old communicates with single words. Which action should the nurse take first?" (Answer: Document the finding and refer for a comprehensive developmental evaluation).
*
Parent Teaching: "A parent of a child with intellectual disability says, 'I just want him to be normal.' Which response by the nurse is best?" (Answer: Focus on the child's strengths and achievable goals).
*
Differentiating Disorders: The same scenario could ask you to choose between ID, ASD, and Global Developmental Delay based on subtle clues in the presentation.
