Each group of letters in the following triads is related to the subsequent one following a certain logic. Select the set in which the triad follows the same logic.
CROW - RCOW - WRCO
DOSE - ODSE - EODS

Appeared in: DSSSB 13 August 2024

Explanation

The logic involves a two-step transformation: first, the initial two letters of the word are swapped, and second, the last letter of the newly formed word is moved to the beginning.
Applying this to 'TIRD': swapping the first two letters (T and I) results in 'ITRD'.
Then, taking 'ITRD' and moving its last letter (D) to the front results in 'DITR'.
This sequence, TIRD → ITRD → DITR, perfectly matches the transformation pattern shown in the examples (CROW → RCOW → WRCO and DOSE → ODSE → EODS).

Option B: The second transformation is incorrect. After swapping 'L' and 'A' in 'LANG' to get 'ALNG', the last letter 'G' should move to the front, resulting in 'GALN'. The option incorrectly shows 'GANG'.
Option C: The first transformation is incorrect. Swapping the first two letters of 'GIVE' ('G' and 'I') should result in 'IGVE'. The option incorrectly shows 'GVIE'.
Option D: The second transformation is incorrect. After swapping 'M' and 'A' in 'MALE' to get 'AMLE', the last letter 'E' should move to the front, resulting in 'EAML'. The option incorrectly shows 'ALER'.

Clinical Relevance

Nursing practice connection: Knowing Logical Reasoning: Letter Shifting and Pattern Recognition helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
While not a clinical question, the underlying skill of pattern recognition is crucial in nursing.
Nurses use pattern recognition to identify subtle changes in a patient's vital signs, recognize symptom clusters indicative of a specific condition, and detect adverse drug reactions.
What if? If a patient's heart rate consistently drops 10 beats per minute 30 minutes after a new medication is administered, recognizing this pattern is the first step to identifying a potential adverse effect and intervening appropriately.

How to Approach the Question

First, carefully analyze the two examples (CROW and DOSE) to determine the exact step-by-step logic of the transformation.
Break the logic into two distinct steps: what happens from the first word to the second, and what happens from the second word to the third.
For the examples, the logic is: 1) Swap the first two letters. 2) Move the last letter of the resulting word to the front.
Systematically apply this two-step logic to the first word of each option.
Compare your derived second and third words with the ones provided in the option.
The option that matches your derived words at both steps is the correct answer.
