4. D

   yellow

Explanation

• The question is a type of coding-decoding problem that tests logical reasoning.
• First, determine the actual color of the object in question. The sky is blue.
• Next, look at the code provided in the question to see what 'blue' is called.
• The problem states: "'blue' is called 'pink'".
• Therefore, based on this substitution, the color of thesky is 'pink'.

Why Other Options Were Wrong

• Option A: This is an incorrect substitution. 'Green' is called 'white' according to the code, which is not related to the color of the sky.
• Option B: This is the actual color of the sky, but the question asks for the coded color, not the real one. The code explicitly renames 'blue' to 'pink'.
• Option D: This is an incorrect substitution. According to the code, 'yellow' is called 'blue'. This is the reverse of the logic needed to solve the problem.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Coding-Decoding Reasoning as background academic context rather than a clinical decision trigger.
• This is a general intelligence question, not a clinical one.
• It assesses logical deduction and the ability to follow a set of rules, which are foundational skills for problem-solving in any professional field, including nursing.
• For example, a nurse must follow specific protocols (rules) for medication administration or wound care, and misinterpreting a step can have serious consequences.

How to Approach the Question

• First, identify the core fact the question is based on. In this case, it's the color of the sky.
• Establish the real-world answer: The sky is blue.
• Carefully read the coding rule provided in the question specifically for the word 'blue'.
• The question states, "'blue' is called 'pink'".
• Apply this single, direct substitution to find the coded answer.
• Avoid the common mistake of following a chain of substitutions (e.g., 'yellow' is 'blue', so the answer is 'yellow'). The question asks what 'blue' is called, not what is called 'blue'.
