Blood is related to Artery in the same way as water is related to

Appeared in: RRB Staff Nurse Mumbai-2015

Explanation

The question presents an analogy where the relationship is between a fluid and its transport vessel.
Blood is a fluid that is transported through the body by arteries, which act as conduits.
Following this pattern, water is a fluid that is transported through pipes.
Therefore, 'Pipe' is the correct word to complete the analogy 'Blood is to Artery as Water is to Pipe'.

Option A: A vein is a blood vessel that carries blood back to the heart. It is a conduit for blood, not water.
Option C: The aorta is the main and largest artery in the body. It is a specific type of artery that carries blood from the heart.
Option D: A straw is a tube used for drinking. While it can convey water, 'pipe' is a better analogy for a systemic transport channel, similar to an artery in the circulatory system.

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 is a general intelligence and reasoning question, not a clinical one.
The ability to use analogical reasoning is a crucial critical thinking skill for nurses. It helps in understanding complex physiological processes by comparing them to more familiar systems (e.g., comparing the electrical conduction of the heart to an electrical circuit).
This skill is also vital for patient education, as nurses often use simple analogies to explain complex medical concepts to patients and their families.

How to Approach the Question

First, identify the specific relationship between the first pair of words (Blood and Artery). The relationship is 'fluid' to 'conduit'.
Next, apply this same relationship to the second word (Water). You are looking for a conduit for water.
Evaluate the given options to see which one best fits the established relationship.
Eliminate options that do not fit. 'Vein' and 'Aorta' are incorrect because they carry blood.
Choose the best fit from the remaining options. 'Pipe' is a more systemic and general conduit for water than 'Straw', making it the stronger analogy.
