Hand : wrist :: foot : ?

Appeared in: SGPGI Nursing Officer-2023

Explanation

The question is based on an analogy, which requires identifying the relationship between the first pair of words and applying it to the second.
The relationship between 'Hand' and 'wrist' is that of a body part to its connecting joint. The wrist connects the hand to the arm.
Applying this 'part-to-joint' relationship to the 'foot', the corresponding connecting joint is the ankle, which connects the foot to the leg.

Option A: 'Length' is a physical dimension or measurement. It does not fit the anatomical relationship of 'body part : joint'.
Option B: 'Shoe' is an external object, an item of clothing worn on the foot. It is not an anatomical part.
Option D: 'Leg' is the larger limb segment to which the foot is attached. The analogy requires the specific joint, not the entire limb.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Analogical Reasoning as background academic context rather than a clinical decision trigger.
While a general knowledge question, understanding anatomical relationships is fundamental to nursing practice for accurate patient assessment, documentation, and performing procedures.
For example, nurses assess pulse points at these joints: the radial artery at the wrist and the posterior tibial and dorsalis pedis arteries near the ankle.
These areas are also common sites for injury (sprains, fractures) and require precise anatomical knowledge for proper splinting and care.

How to Approach the Question

First, identify the relationship between the first pair of words: 'Hand' and 'wrist'. Recognize that the wrist is the joint that connects the hand to the arm.
Formulate this relationship as a general rule. In this case, the rule is 'Extremity : Connecting Joint'.
Apply this rule to the second word provided, 'foot'. You are looking for the connecting joint of the foot.
Evaluate the given options against this rule.
Eliminate options that do not fit the 'joint' category: 'Length' (a measurement), 'Shoe' (an accessory), and 'Leg' (the larger limb).
Select the remaining option, 'Ankle', as it correctly fits the established analogical pattern.
