**Question:** IQ in moderate mental retardation -

A. 70-80
B. 60-70
C. 80-90
D. 90-110

**Correct Answer:** A. 70-80

**Core Concept:**

Moderate mental retardation is a term used to describe individuals with an Intelligence Quotient (IQ) score between 50-70, indicating significant intellectual disability. IQ is a measure of intellectual functioning that compares an individual's cognitive abilities to a standard population mean (IQ of 100) and a standard deviation (SD of 15).

**Why the Correct Answer is Right:**

The IQ range of 70-80 represents the moderate intellectual disability category. In this range, individuals experience significant limitations in their ability to learn, adapt, and function independently in daily life tasks. Their cognitive skills and reasoning are below average, making it difficult for them to engage in complex activities, requiring direct supervision, or live independently.

**Why Each Wrong Option is Incorrect:**

A. IQ of 60-70 (Option B) falls within the moderate mental retardation range, but it is slightly lower than the correct range (70-80).

B. IQ of 80-90 (Option C) falls within the borderline intellectual functioning range (90-104), not moderate mental retardation.

D. IQ of 90-110 (Option D) falls within the average intellectual functioning range (90-110), representing individuals without intellectual disabilities.

**Why It Matters:**

Understanding the IQ ranges related to intellectual disabilities is crucial for healthcare professionals, educators, and caregivers to provide appropriate support, interventions, and accommodations for individuals in each category. Knowing the distinction among mild, moderate, severe, and profound intellectual disabilities helps allocate resources and services accordingly, ensuring that individuals receive the optimal care and assistance.

**Clinical Pearl:**

In cases of moderate mental retardation, it is vital to employ adaptive strategies, specialized education, and supportive environments to facilitate personal growth, independence, and social integration. Teamwork between healthcare professionals, educators, and families is essential to meet the unique needs of individuals with moderate mental retardation, allowing them to achieve their full potential and lead a fulfilling life.
