CAT is called DBU so DOG is called?

Appeared in: RML PRE 2025

Explanation

The core logic is a simple alphabetical shift where each letter of the original word is moved one position forward.
The word 'CAT' is transformed into 'DBU' by shifting C to D, A to B, and T to U.
Applying this same +1 shift pattern to the word 'DOG' results in 'EPH' (D -> E, O -> P, G -> H).

Option B: This option incorrectly keeps the first letter as 'D'. The pattern requires shifting 'D' one step forward to 'E'.
Option C: This option incorrectly shifts 'D' by two places to 'F' and keeps 'O' and 'G' the same. This does not follow the consistent +1 pattern.
Option D: This option correctly shifts the first letter ('D' to 'E') but fails to shift the last two letters ('O' and 'G'). The pattern must be applied to all letters in the word.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain This question tests logical reasoning skills, specifically letter coding and pattern recognition 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 pattern recognition daily to identify changes in a patient's condition, interpret lab results, and recognize adverse drug reactions.
Strong problem-solving skills are essential for critical thinking and making sound clinical judgments under pressure.

How to Approach the Question

First, analyze the relationship between the first pair of words ('CAT' and 'DBU').
Look for a consistent pattern. Check for letter shifts (forward or backward), reversals, or other logical transformations.
In this case, notice that each letter in 'DBU' is the next letter in the alphabet after the corresponding letter in 'CAT' (C->D, A->B, T->U).
Confirm the pattern is a consistent '+1' shift for every letter.
Apply this identified pattern to the second word, 'DOG'.
Shift each letter of 'DOG' forward by one position: D -> E, O -> P, G -> H.
