One of the category of mental retardation for a child with I.Q. of 45 is:

Appeared in: IGNOU PB Bsc Entrance-2023

Explanation

The correct classification for a child with an IQ of 45 is Moderate Intellectual Disability.
This category typically includes individuals with an IQ in the range of 35 to 50.
Individuals in this range are often considered 'trainable' and can learn basic communication, social, and self-care skills with support.
Academic achievement is usually limited to a second- or third-grade level, and they require moderate supervision throughout their lives.

Why Other Options Were Wrong

Option A: This category is for individuals with an IQ between 50 and 70. The child's IQ of 45 is below this range.
Option C: This category is for individuals with an IQ between 20 and 35. The child's IQ of 45 is above this range.
Option D: This category is for individuals with an IQ below 20. The child's IQ of 45 is significantly higher than this range.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of Intellectual Disability by IQ Score as background academic context rather than a clinical decision trigger.
A nurse must understand these classifications to develop an appropriate plan of care, set realistic goals, and provide effective patient and family education.
This knowledge helps in anticipating the level of support a patient will need for daily activities, communication, and safety.
What if the question stated the child had an IQ of 75 but significant deficits in social skills and self-care? While the IQ is in the 'borderline' range, the deficits in adaptive functioning would still be the primary focus for nursing interventions and support, and a diagnosis of intellectual disability might not be appropriate, but other developmental disorders could be considered.

How to Approach the Question

First, identify the key piece of information in the question, which is the child's IQ score of 45.
Recall the standard classification system for intellectual disability, which categorizes severity based on IQ ranges.
The main categories are Mild, Moderate, Severe, and Profound.
Match the given IQ score (45) to the corresponding range. The range for Moderate Intellectual Disability is approximately 35-50.
Select the option that matches this classification.
Eliminate the other options by confirming that the IQ of 45 does not fall into their respective ranges.
