DIRECTIONS: Select the related letters from the given alternatives-ABCD: HGFE :: OPQR:?

Appeared in: DHS Staff Nurse - 2018 (Shift-2nd)

Explanation

The core logic involves identifying the sequence of letters that follows the first group.
In the pair ABCD:HGFE, the letters after D are E, F, G, H.
The second term, HGFE, is the reverse of the sequence EFGH.
Applying this pattern to OPQR, the letters that follow R are S, T, U, V.
Reversing the sequence STUV results in VUTS, which is the correct answer.

Option A: This is an incorrect arrangement of the correct letters. The pattern requires a complete reversal of the sequence 'STUV', which is 'VUTS', not 'VTSU'.
Option B: This option does not follow the established pattern. While 'S' is the correct first letter in the forward sequence (after R), the subsequent letters (H, G, V) do not fit the logic derived from the first pair.
Option D: This is a random sequence of letters that bears no logical relationship to OPQR based on the pattern established by ABCD:HGFE.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Analogical Reasoning (Letter Series) as background academic context rather than a clinical decision trigger.
This question assesses logical reasoning and pattern recognition, which are fundamental cognitive skills for effective problem-solving in any professional field.
In nursing, the ability to identify patterns is crucial for interpreting trends in a patient's vital signs, recognizing the progression of a disease, or understanding lab results.
Strong analytical skills help nurses make sound clinical judgments and respond appropriately to changes in a patient's condition.

How to Approach the Question

First, carefully examine the relationship between the first pair of letter groups (ABCD and HGFE).
Identify the rule or pattern connecting them. Notice that ABCD are consecutive letters, and HGFE are the next four letters in the alphabet, but written in reverse.
Confirm the pattern: The letters after D are E, F, G, H. Reversing this gives HGFE. The pattern is confirmed.
Apply this same rule to the second group (OPQR).
Determine the next four letters after R, which are S, T, U, V.
Reverse this new sequence (STUV) to get VUTS.
