In a certain code language 'HOSPITAL' is coded as 'CTNUDYVQ and 'DOCTOR' is coded as 'YTXYJW' then how will DISEASE be coded in the same language?

1. A

   YNNJUXZ

2. B

   YNNJVXJ

3. C

   YNMLJVXZ

4. D

   YNNJVXZ

Explanation

• The coding pattern involves an alternating positional shift of letters in the English alphabet.
• The letter at an odd position (1st, 3rd, 5th, etc.) is shifted 5 places backward.
• The letter at an even position (2nd, 4th, 6th, etc.) is shifted 5 places forward.
• Applying this rule to 'DISEASE': D(4)-5 -> Y(25), I(9)+5 -> N(14), S(19)-5 -> N(14), E(5)+5 -> J(10), A(1)-5 -> V(22), S(19)+5 -> X(24), E(5)-5 -> Z(26).
• This results in the code YNNJVXZ.

Why Other Options Were Wrong

• Option A: This option incorrectly codes the 5th letter 'A' as 'U' and the 6th letter 'S' as 'X'. According to the pattern, 'A' should be shifted backward by 5 to get 'V', and 'S' should be shifted forward by 5 to get 'X'. The code has an error in the 5th position.
• Option B: This option incorrectly codes the last letter 'E' as 'J'. The 7th position is an odd position, so the letter 'E' should be shifted backward by 5, resulting in 'Z', not 'J'.
• Option C: This option incorrectly codes the 3rd letter 'S' as 'M' and the 4th letter 'E' as 'L'. The pattern is not followed correctly from the third letter onwards.

Clinical Relevance

• Nursing practice connection: Knowing Logical Reasoning: Coding-Decoding by Letter Shifting helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
• This question tests logical reasoning and pattern recognition, which are essential cognitive skills for nurses.
• Nurses use pattern recognition to identify changes in a patient's condition, interpret vital signs, and recognize symptom clusters.
• Strong problem-solving skills help in making quick, effective clinical decisions under pressure.

How to Approach the Question

• First, analyze the relationship between the letters of the given word ('HOSPITAL') and its corresponding code ('CTNUDYVQ').
• Calculate the positional difference in the alphabet between the first letter 'H' and 'C', then the second letter 'O' and 'T', and so on.
• Identify the emerging pattern. You'll notice a repeating sequence of operations (e.g., -5, +5, -5, +5...).
• Confirm this pattern by applying it to the second example ('DOCTOR' -> 'YTXYJW').
• Once the pattern is confirmed, apply it systematically to the target word ('DISEASE') to derive the correct code.
• Compare your derived code with the given options to find the match.
