Physiological Jaundice occurs after?
Appeared in: NIMHANS Nursing Officer - 2019
Explanation
- Physiological jaundice is a normal, transient condition in newborns resulting from the immaturity of the liver's bilirubin conjugation pathways.
- The key diagnostic criterion is its onset, which occurs after the first 24 hours of life, typically becoming visible between day 2 and day 3.
- This timing distinguishes it from pathological jaundice, which appears within the first 24 hours and indicates an underlying disease process.
- In term infants, bilirubin levels in physiological jaundice peak around the 3rd to 5th day and then gradually decline.
Why Other Options Were Wrong
- Option B: This describes pathological jaundice. The appearance of jaundice within the first 24 hours of life is a red flag for an underlying medical condition.
- Option C: This is too late for the initial onset of typical physiological jaundice. While jaundice can persist beyond 7 days (e.g., breast milk jaundice), its initial appearance is much earlier.
- Option D: This option is incorrect because a correct answer is provided in the options. The onset of physiological jaundice is a well-defined clinical parameter.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Differentiating physiological from pathological jaundice based on the time of onset in a newborn as background academic context rather than a clinical decision trigger.
- A nurse's primary responsibility is to monitor all newborns for jaundice every 8-12 hours. The exact timing of onset is a critical piece of data to report.
- Accurate assessment and documentation help differentiate a normal physiological process from a pathological one, ensuring timely intervention and preventing complications like kernicterus (bilirubin-induced brain damage).
- Nurses play a key role in educating parents about the signs of worsening jaundice and the importance of follow-up appointments after discharge.
How to Approach the Question
- First, identify the core concept of the question, which is 'Physiological Jaundice'.
- Recall the defining characteristics of physiological jaundice. The most critical factor that distinguishes it from pathological jaundice is the time of onset.
- Remember the rule: Jaundice appearing after 24 hours is typically physiological. Jaundice appearing within 24 hours is pathological.
- Evaluate the given options based on this rule.
- Option A, 'After 24 hours', directly matches the definition of physiological jaundice.
- Options B and C describe timeframes associated with pathological jaundice or other types of jaundice, making them incorrect for this specific question.
Concept Tested & Keywords
