In a certain code, NURSE is written as QXUVH. How would BLOOD be written in that code?
Appeared in: RML MAINS 2025
Explanation
- The coding pattern involves a simple forward alphabetical shift.
- Each letter in the original word is replaced by the letter that is three positions ahead of it in the English alphabet.
- Applying this "+3" rule to "BLOOD" (B+3=E, L+3=O, O+3=R, O+3=R, D+3=G) results in the code "EORRG".
Why Other Options Were Wrong
- Option B: This option incorrectly codes the second letter 'L' as 'N'. An 'N' would result from a +2 shift (L → M → N), which violates the established +3 pattern.
- Option C: This option incorrectly codes the third letter 'O' as 'R' and the fourth letter 'O' as 'S'. The 'S' would be a +4 shift, breaking the consistent +3 pattern.
- Option D: This option incorrectly codes the last letter 'D' as 'H'. An 'H' would result from a +4 shift (D → E → F → G → H), which is inconsistent with the +3 rule derived from 'NURSE' → 'QXUVH'.

Clinical Relevance
- Nursing practice connection: Knowing Logical Reasoning - Coding and Decoding helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
- Logical reasoning questions assess critical thinking and problem-solving skills, which are essential for nurses in clinical decision-making, prioritizing care, and troubleshooting equipment.
- While not directly clinical, the ability to quickly identify patterns is analogous to recognizing patterns in patient symptoms, lab results, or vital sign trends.
- What if? - If the code for NURSE was LSNQC, the pattern would be a '-2' shift (N-2=L, U-2=S, etc.). In that case, the code for BLOOD would be ZJMMB (B-2=Z, L-2=J, O-2=M, D-2=B).
How to Approach the Question
- First, analyze the relationship between the given word ('NURSE') and its code ('QXUVH').
- Check for simple alphabetical shifts (forward or backward) by comparing the position of each corresponding letter. For example, N is the 14th letter and Q is the 17th, a difference of +3.
- Verify if this pattern (+3 shift) holds true for all letters in the word 'NURSE'.
- Once the pattern is confirmed, apply the same rule to the target word ('BLOOD').
- Shift each letter of 'BLOOD' forward by three positions to derive the new code.
- Compare the resulting code with the given options to find the correct answer.
