A is the father of B and C. B is married to D, and they have two children. C is unmarried.

How many children does A have?

Appeared in: UP NHM CHO 7 Sept 2022 (Shift-2)

Explanation

The problem statement explicitly says, 'A is the father of B and C,' which directly names his two children.
This is a question of direct relationship identification.
Information about marriages (B is married to D) and grandchildren (B and D's two children) is designed to be distracting but does not change the number of A's direct children.

Option B: This is incorrect because the statement explicitly names two children, B and C.
Option C: This is incorrect. This number is derived by adding A's two children (B and C) and his two grandchildren, which is a misinterpretation of the question.
Option D: This is incorrect. There is no information in the text to support A having three children. This might come from incorrectly including D (B's spouse) in the count of children.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning and Family Relationships as background academic context rather than a clinical decision trigger.
While not a clinical question, this type of logical reasoning is crucial for nurses when taking a family medical history to accurately map relationships and identify genetic predispositions.
Accurately identifying direct relationships (parent-child) versus other relations (in-laws, grandchildren) is essential for constructing a genogram.
What if the question asked 'How many descendants of A are mentioned?' The answer would then be four (two children and two grandchildren).

How to Approach the Question

First, carefully read the entire problem statement to understand all the given relationships.
Identify the specific question being asked. Here, it is 'How many children does A have?'.
Scan the text for the sentence that directly answers this question. The statement 'A is the father of B and C' is the key.
Isolate the relevant information (direct children) from irrelevant information (grandchildren, spouses, marital status).
Count the individuals who fit the required relationship (children) to arrive at the final answer.
