Drug-Disease: Book...

Appeared in: MNS 2015

Explanation

The question requires identifying the logical relationship between a pair of words and applying it to another.
The primary relationship is 'Solution to a Problem' or 'Remedy for an Ailment'.
A 'Drug' is the remedy for a 'Disease'.
Following this pattern, a 'Book' is the remedy for 'Illiteracy', as education and reading are the primary means to overcome the inability to read and write.

Option A: A book is a source of knowledge, not a cure for it. The relationship is one of containment or provision, not remedy.
Option B: A teacher uses a book as a tool for instruction. A book does not 'cure' or 'eradicate' a teacher.
Option D: A writer is the creator of a book. This represents a 'Creator : Creation' relationship, which is different from the 'Remedy : Ailment' relationship in the question.

Clinical Relevance

Nursing practice connection: Knowing Analogical Reasoning helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
While not a clinical question, analogical reasoning is a critical skill for nurses.
Nurses use analogical reasoning to apply knowledge from one clinical situation to another similar, but not identical, one.
For example, understanding the principles of sterile technique for one procedure helps a nurse apply them correctly to a different sterile procedure.

How to Approach the Question

First, identify the relationship between the first pair of words ('Drug' and 'Disease'). Ask yourself: 'How is a drug related to a disease?'
Formulate this relationship in a clear sentence: 'A drug is used to cure a disease.' This establishes a 'remedy for an ailment' pattern.
Next, take the first word of the second pair ('Book') and apply the same relationship.
Ask: 'A book is used to cure what?'
Evaluate the given options to see which one logically completes this sentence.
Illiteracy is the only option that represents an 'ailment' or 'problem' that a book can 'cure' or 'remedy'.
