According to ICD 10 classification, F20.0 is:

Appeared in: DSSSB October 2024

Explanation

The International Classification of Diseases, 10th Revision (ICD-10) uses specific codes to classify different types of schizophrenia.
The code F20.0 specifically designates Paranoid Schizophrenia.
This subtype's clinical picture is dominated by relatively stable delusions and hallucinations, while affect and volition are less disturbed.
The other options correspond to different codes within the F20 category.

Option A: Residual schizophrenia is incorrect. This subtype, coded as F20.5, represents a chronic stage of the illness where negative symptoms (like emotional blunting and social withdrawal) are more prominent than active positive symptoms like delusions.
Option B: Hebephrenic schizophrenia is incorrect. This subtype is coded as F20.1 and is characterized by disorganized thinking, inappropriate or flat affect, and unpredictable behavior.
Option D: Catatonic schizophrenia is incorrect. This subtype is coded as F20.2 and is defined by significant psychomotor disturbances, which can range from stupor and waxy flexibility to extreme agitation.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain ICD-10 classification of schizophrenia subtypes as background academic context rather than a clinical decision trigger.
Accurate ICD-10 coding is a critical nursing responsibility for documentation, ensuring continuity of care, and for administrative purposes like billing and health statistics.
Understanding the different subtypes of schizophrenia helps nurses anticipate patient behaviors and tailor care plans. For a patient with paranoid schizophrenia (F20.0), a key nursing intervention is to build trust and not challenge their delusions directly.
What if? If a patient presented with severe psychomotor disturbances like posturing and mutism, the diagnosis would be Catatonic Schizophrenia (F20.2), and the nursing priority would shift to ensuring physical safety, nutrition, and managing the risks of immobility.

How to Approach the Question

This is a factual recall question that tests your knowledge of a specific classification system.
First, identify the key term in the question, which is the code 'F20.0'.
Next, recall the ICD-10 classification for mental and behavioral disorders, specifically the section on schizophrenia (F20-F29).
Match the specific code (F20.0) to its corresponding diagnosis from the options provided.
Eliminate the other options by recalling their respective ICD-10 codes (F20.1, F20.2, F20.5).
