BLOOD is related to ARTERY in the same way as water is related to

Appeared in: RRB Staff Nurse Ahmedabad-2015

Explanation

The core relationship is 'fluid to its conduit'. Blood is a fluid that flows through an artery, which acts as a conduit.
Applying this logic, water is a fluid, and a pipe is a man-made conduit designed to transport water.
Therefore, 'Pipe' correctly completes the analogy by maintaining the 'fluid-in-a-conduit' relationship.

Option A: A vein is a type of blood vessel that carries blood back to the heart; it is not a conduit for water.
Option C: The aorta is the body's main artery. Like a vein, it is part of the circulatory system and carries blood, not water.
Option D: A straw is used for drinking via suction. An artery transports blood under pressure within a closed system. A pipe, used for conveyance, is a much better functional parallel.

Clinical Relevance

Nursing practice connection: Knowing Analogical Reasoning helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
This question tests analogical reasoning, a critical thinking skill nurses use to understand complex physiological processes and explain them to patients.
For instance, a nurse can explain a blocked coronary artery to a patient by comparing it to a clogged pipe in their home, making the medical concept easier to grasp.
This reasoning skill also helps in troubleshooting equipment, where a kinked IV line can be understood as an obstruction similar to a bent straw or a blocked artery.

How to Approach the Question

First, identify the relationship between the first pair of words: BLOOD and ARTERY.
Define this relationship clearly: Blood is a fluid that is transported through an artery, which serves as its channel or conduit.
Next, take the third word, 'water', and apply the same 'fluid through a conduit' relationship.
Examine the given options to find the one that functions as a conduit for water.
Vein and Aorta are blood vessels. A straw is for drinking. A pipe is a conduit for transporting water.
Conclude that 'Pipe' is the correct answer as it perfectly mirrors the function of an artery in the context of water.
