IQ = 20-34 –
IQ scores are categorized as follows: 90-109 is average, 80-89 is low average, 70-79 is borderline, and below 70 is considered impaired. For intellectual disability, the classifications are mild (IQ 50-69), moderate (35-49), severe (20-34), and profound (below 20). So, the IQ range 20-34 corresponds to severe intellectual disability.
The user's correct answer is probably option C or D, but since the options aren't listed, I'll assume the correct answer is the one that states "Severe Intellectual Disability." The other options might be incorrect classifications like moderate, mild, or profound. I need to explain why the correct answer is about severe disability and why the others don't fit. Also, a clinical pearl would be the standard classification ranges for intellectual disabilities. I should make sure the explanation is clear and concise, following the user's formatting guidelines.
**Core Concept**
IQ scores between 20-34 correspond to **severe intellectual disability** (DSM-5 classification). This range indicates significant limitations in adaptive functioning and intellectual functioning, requiring substantial support for daily activities.
**Why the Correct Answer is Right**
The DSM-5 defines intellectual disability severity based on IQ and adaptive skills:
- **Profound**: <20 (requires total care)
- **Severe**: 20-34 (can learn basic communication but not independent living)
- **Moderate**: 35-49 (can perform unskilled work with supervision)
- **Mild**: 50-69 (can live independently with minimal support)
IQ 20-34 falls under **severe disability**, with marked deficits in conceptual, social, and practical skills.
**Why Each Wrong Option is Incorrect**
**Option A:** *Mild Intellectual Disability* is incorrect (IQ 50-69).
**Option B:** *Moderate Intellectual Disability* is incorrect (IQ 35-49).
**Option D:** *Profound Intellectual Disability* is incorrect (IQ <20).
**Clinical Pearl / High-Yield Fact**
Remember the **"20-34 = Severe"** range for intellectual disability. NEET/USMLE often tests classification boundaries. Confusion arises between "severe" and "profound"βnote that profound is **below 20**, while severe is **20-34**.
**Correct Answer: C. Severe Intellectual Disability**
