A statement is given followed by two conclusions. Find which conclusion(s) is /are true based on the given statement.

Statement:

M < A = R > D >_ U > N

Conclusions:

i) R > N
ii) A > D
iii) M < U

1. A

   Only i) and ii) follow

2. B

   Only ii) and iii) follow

3. C

   All follow

4. D

   Only ii) follows

Explanation

• Conclusion (i) R > N is correct because the path R > D ≥ U > N consistently shows a greater-than relationship from R to N.
• Conclusion (ii) A > D is correct because the path A = R > D directly implies that since A is equal to R, and R is greater than D, A must also be greater than D.
• Both conclusions (i) and (ii) can be logically and definitively proven based on the given statement.

Why Other Options Were Wrong

• Option B: This option is incorrect because it includes conclusion (iii) M < U, which is false. No definite relationship can be established between M and U due to opposing inequality signs (< and >) in the path connecting them.
• Option C: This option claims all conclusions follow, but conclusion (iii) is false. The presence of opposing inequality signs in the path from M to U makes it impossible to determine their relationship.
• Option D: This option is incorrect because it omits conclusion (i) R > N, which is also true. The relationship R > D ≥ U > N clearly establishes that R is greater than N.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain This question tests logical deduction skills, specifically the ability to interpret and draw conclusions from a series of chained inequalities as background academic context rather than a clinical decision trigger.
• This is a logical reasoning question, not a clinical one. However, the skill it tests is crucial in nursing.
• Nurses must constantly make logical deductions based on changing patient data (vitals, lab results, symptoms) to assess conditions and prioritize care.
• For example, if a patient's blood pressure is decreasing while their heart rate is increasing, a nurse logically deduces the patient may be experiencing shock.

How to Approach the Question

• First, carefully read the given statement, which is a chain of inequalities: M < A = R > D ≥ U > N.
• Next, analyze each conclusion one by one to determine its validity.
• For Conclusion (i) R > N, trace the path from R to N in the statement. The path is R > D ≥ U > N. Since all signs show a 'greater than' or 'greater than or equal to' relationship flowing from R to N, the conclusion R > N is true.
• For Conclusion (ii) A > D, trace the path from A to D: A = R > D. Since A equals R, you can substitute A for R, which gives A > D. This conclusion is true.
• For Conclusion (iii) M < U, trace the path from M to U: M < A = R > D ≥ U. Notice the opposing signs (< and >) in the path between M and U. When signs are opposite, no definite conclusion can be drawn. This conclusion is false.
• Finally, select the option that matches your findings. Since only conclusions (i) and (ii) are true, choose the corresponding option.
