Find the odd one from the following?

Appeared in: JSSH Staff Nurse - 2019

Explanation

The question requires identifying the term that does not fit the pattern established by the others.
The pattern connects 'Cub', 'Puppy', and 'Duckling' as all being terms for the young of an animal.
'Rodent' breaks this pattern because it is a biological classification (an order of mammals), not a term for a juvenile animal.
Therefore, 'Rodent' is the odd one out based on the logical category of 'names for young animals'.

Option A: A 'Cub' is the term for a young animal, specifically of carnivorous species like lions or bears. This fits the pattern of the other correct options.
Option C: A 'Puppy' is the term for a young dog. This fits the pattern of being a name for a juvenile animal.
Option D: A 'Duckling' is the term for a young duck. This fits the pattern of being a name for a juvenile animal.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning: Classification and Categorization as background academic context rather than a clinical decision trigger.
This question tests logical reasoning and categorization skills, which are foundational for clinical problem-solving and differential diagnosis.
Nurses must constantly categorize information, such as symptoms, patient data, and medication types, to make sound clinical judgments.
What if the options were 'Calf', 'Foal', 'Lamb', and 'Cow'? In that case, 'Cow' would be the odd one out, as it is an adult animal, while the others are all young animals.

How to Approach the Question

First, read all the options to understand the set of words provided: Cub, Rodent, Puppy, Duckling.
Analyze the relationship between the words. Think about what they have in common. In this case, three of the words (Cub, Puppy, Duckling) are names for the young of animals.
Identify the word that does not share this common characteristic. 'Rodent' is not a name for a young animal; it's a classification of a type of mammal.
Confirm your logic. The common theme is 'juvenile animal name'. 'Rodent' is an 'animal order'. This confirms it is the odd one out.
Select the option that breaks the established pattern.
