Clinical Relevance
Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Order of planets in the solar system as background academic context rather than a clinical decision trigger.
This is a general knowledge question and does not have direct clinical relevance to nursing practice.
A broad knowledge base, including non-nursing subjects, is often assessed in the general aptitude sections of nursing entrance examinations.
What if? - If the stem changed one defining clue so that Earth no longer matched, reassess the option whose mechanism, classification, or indication now fits the revised presentation.
