Explanation

• The task is to find a specific pattern: Vowel -> Symbol -> Non-Vowel.
• The symbols in the series are &, #, *, &, @.
• A systematic check of each symbol reveals that none meet both required conditions.
• The symbol '@' is preceded by a vowel ('A'), satisfying the first condition.
• However, '@' is followed by another vowel ('E'), which fails the second condition (must be followed by a non-vowel).
• Therefore, the total count of such symbols is zero.

Why Other Options Were Wrong

• Option B: This option is incorrect. A common error is to identify the symbol '@' which is preceded by the vowel 'A' but fail to check the second condition that it must be followed by a non-vowel. Since '@' is followed by 'E' (a vowel), it does not qualify.
• Option C: This is an incorrect count. There are no symbols in the series that satisfy both conditions.
• Option D: This is an incorrect count. There are no symbols in the series that satisfy both conditions.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning: Alphanumeric and Symbol Series Analysis as background academic context rather than a clinical decision trigger.
• While not a clinical question, this type of logical reasoning tests attention to detail and the ability to follow multi-step instructions precisely.
• These cognitive skills are crucial in nursing for tasks like medication administration, where the right drug, dose, route, and time must be correctly followed without error.
• It also relates to interpreting complex patient data or charts, where multiple conditions or parameters must be considered simultaneously to make a correct clinical judgment.

How to Approach the Question

• First, carefully read the question to understand the exact conditions. Here, it's a three-part pattern: Vowel -> Symbol -> Non-Vowel.
• Identify the set of vowels (A, E, I, O, U) and what constitutes a 'symbol' in the context of the series.
• Scan the series from left to right, stopping at each symbol.
• For each symbol found, look at the character immediately to its left. Check if it is a vowel.
• If the preceding character is a vowel, then look at the character immediately to the right of the symbol. Check if it is a non-vowel.
• Only if both conditions are met, increment your count. Tally the final count to select the correct option.
