A mild grade of mental deficiency is confirmed when the child has an Intelligence quotient (IQ) that varies between?

Appeared in: DSSSB - 29 August 2019 (Shift-1)

Explanation

  • According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), mild intellectual disability is defined by an IQ score between 50 and 70.
  • This level of disability accounts for approximately 85% of all cases of intellectual disability.
  • Individuals with mild intellectual disability can typically acquire academic skills equivalent to a sixth-grade level by their late teens.
  • They can often achieve social and vocational skills sufficient for minimal self-support but may require guidance during times of stress.

Why Other Options Were Wrong

  • Option A: An IQ range of 30-40 corresponds to severe intellectual disability, not mild.
  • Option B: An IQ range of 40-50 is classified as moderate intellectual disability.
  • Option C: An IQ range of 20-30 falls within the severe intellectual disability category.

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 Level as background academic context rather than a clinical decision trigger.
  • Nurses must understand the different levels of intellectual disability to tailor communication, patient education, and care plans effectively. For a patient with mild intellectual disability, a nurse would use clear, simple language and verify understanding, knowing the patient can often participate in their own care decisions.
  • Recognizing the functional capacity associated with each IQ level helps in setting realistic goals for patients and providing appropriate support to them and their families.
  • What if the patient had an IQ of 40? The nurse's approach would shift significantly. Instead of focusing on 6th-grade level education, the focus would be on teaching basic self-care (hygiene, dressing), ensuring safety, and using very simple, concrete communication, as this falls into the moderate disability range.
How to Approach the Question
  • First, identify the key terms in the question: 'mild grade' and 'Intelligence quotient (IQ)'.
  • This is a factual recall question that requires knowledge of the standard classification system for intellectual disability.
  • Recall or look up the different levels of severity (mild, moderate, severe, profound) and their corresponding IQ ranges.
  • Compare the IQ ranges given in the options to the standard classification. The range for 'mild' is 50-70.
  • Select the option that matches this established range.
Concept Tested & Keywords
  • Concept Tested: Classification of Intellectual Disability by IQ Level
  • Stem keywords: mental deficiency, Intelligence quotient (IQ), mild grade
  • Lead-in keywords: varies between
  • Clinical cues: Age/sex group narrows the expected diagnosis, intervention, or normal reference range.
