An IQ score of 90 is classified as

Appeared in: ESIC Nursing Officer-7July 2024

Explanation

An Intelligence Quotient (IQ) score of 90 falls within the 'Average' range.
The standard classification for an Average IQ is a score between 90 and 109.
This category represents the largest portion of the general population, centered around the mean score of 100.

Option A: This classification corresponds to an IQ range of 70-79, which is below the score of 90.
Option C: This classification is for IQ scores of 120-129, which is significantly higher than 90.
Option D: This classification, also known as High Average, is for scores of 110-119, which is above 90.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of Intelligence Quotient (IQ) scores as background academic context rather than a clinical decision trigger.
Understanding a patient's cognitive level, as indicated by an IQ score, helps nurses tailor communication and patient education effectively.
For patients with lower IQs, nurses should use simpler language, visual aids, and the 'teach-back' method to ensure comprehension and adherence to treatment plans.
What if? - If a patient's chart noted an IQ of 65, the nurse should recognize this as 'Mild Intellectual Disability' and involve family or caregivers more heavily in the care plan, using very concrete and simple instructions.

How to Approach the Question

First, identify the core task: classifying a specific IQ score (90).
Second, recall the standard IQ classification scale. The key anchor point is that 100 is the mean.
Third, remember the 'Average' range, which typically spans from 90 to 109. This is the most common range.
Fourth, place the given score of 90 within this recalled framework. It falls at the beginning of the 'Average' category.
Finally, select the option that matches this classification and mentally discard the options for lower ('Borderline') and higher ('Bright normal', 'Superior') scores.
