In this question, relationship between different elements is shown in the statement. This statement is followed by three conclusions. Assume the given statement to be true and choose the answer from the given options: Statement: B < R > I ≥ M = D > E Conclusions: i) B < M ii) I > E iii) R > D

1. A

   Only i) and iii) follow

2. B

   All follow

3. C

   Only ii) and iii) follow

4. D

   Only i) and ii) follow

Explanation

• This option correctly identifies that only conclusions (ii) and (iii) logically follow from the main statement.
• Conclusion (ii) I > E is true because the path I ≥ M = D > E simplifies to I ≥ D > E, which means I must be greater than E.
• Conclusion (iii) R > D is true because the path R > I ≥ M = D simplifies to R > I ≥ D, which means R must be greater than D.

Why Other Options Were Wrong

• Option A: This option is incorrect because it includes conclusion (i) B < M, which is false. No definite relationship can be established between B and M due to the opposing signs (< and >) in the path B < R > I.
• Option B: This option claims that all conclusions follow, which is incorrect. Conclusion (i) B < M is false because of the opposing signs in the path connecting B and M.
• Option D: This option is incorrect because it excludes the valid conclusion (iii) R > D. The path R > I ≥ M = D clearly establishes that R is greater than D.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Coded Inequalities as background academic context rather than a clinical decision trigger.
• While not a clinical question, this type of logical reasoning is a foundational skill for nursing.
• Nurses use deductive reasoning to interpret patient data, connect symptoms to potential diagnoses, and evaluate the effectiveness of interventions.
• Strong analytical skills help in prioritizing care, especially when multiple patient needs and data points must be considered simultaneously.

How to Approach the Question

• First, carefully read the main statement that establishes the relationships: B < R > I ≥ M = D > E.
• Next, analyze each conclusion individually by tracing the path between the two elements in the main statement.
• For Conclusion (i) B < M, trace the path B < R > I ≥ M. Notice the opposing signs '<' and '>'. This immediately means no definite conclusion can be drawn. Mark it as false.
• For Conclusion (ii) I > E, trace the path I ≥ M = D > E. Combine the relationships: I is greater than or equal to M, M is equal to D, and D is greater than E. This chain (I ≥ D > E) confirms that I is greater than E. Mark it as true.
• For Conclusion (iii) R > D, trace the path R > I ≥ M = D. Combine the relationships: R is greater than I, I is greater than or equal to M, and M is equal to D. This chain (R > I ≥ D) confirms that R is greater than D. Mark it as true.
• Finally, review your findings: (i) is false, (ii) is true, and (iii) is true. Select the option that matches this result, which is 'Only ii) and iii) follow'.
