The word 'Infallible' is the only option spelled according to standard English conventions.
It is an adjective that means incapable of making mistakes or being wrong.
The word's structure is 'in-' (a prefix for 'not') combined with 'fallible' (capable of error), which originates from the Latin verb 'fallere' (to deceive).
Why Other Options Were Wrong
Option A: This option uses an incorrect vowel. The letter after the 'f' should be 'a', not 'e'.
Option B: This spelling is missing a consonant. The root 'fall' requires a double 'l' in this construction.
Option C: This option uses an incorrect suffix. The correct adjectival suffix is '-ible', not '-ibal'.

Clinical Relevance
Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain English vocabulary and spelling as background academic context rather than a clinical decision trigger.
In nursing documentation, reports, and professional communication, precise spelling is essential to maintain clarity, professionalism, and avoid misinterpretation.
The concept of fallibility is a cornerstone of safe clinical practice. Acknowledging that no diagnostic test or clinical guideline is 'infallible' promotes critical thinking and a holistic patient assessment.
What if? If a nurse consistently makes spelling errors in patient charts, it can undermine their credibility and, in critical situations involving look-alike, sound-alike medications, could contribute to medication errors.
How to Approach the Question
This is a direct recall question that tests your knowledge of English spelling.
First, read the question to understand that you need to identify the correctly spelled word.
Carefully examine each option, looking for common spelling errors such as incorrect vowels (a, e, i), incorrect consonants (single vs. double letters like l vs. ll), and improper suffixes (-ible, -able, -ibal).
Sound out each word phonetically. The correct word, 'In-fall-i-ble', has a distinct pronunciation that can help identify the correct spelling.
Compare the options to your knowledge of standard English. 'Infallible' is the standard and correct spelling.
Eliminate the other options by identifying their specific errors: 'Infellible' (wrong vowel), 'Infalible' (missing 'l'), and 'Infalibal' (wrong suffix).
