Recommended solution to apply on cord at birth is-

Explanation

Current evidence-based guidelines from authoritative bodies like the American Academy of Pediatrics recommend keeping the umbilical cord stump clean and dry.
This practice, known as 'dry cord care,' involves applying no solutions or antiseptics to the cord stump.
Exposing the cord to air allows it to dry more quickly and separate naturally, typically within 1 to 2 weeks, minimizing the risk of chemical irritation.

Option A: Potassium permanganate is a strong oxidizing agent that can cause skin irritation and chemical burns and is not recommended for routine cord care.
Option B: Routine application of Betadine (povidone-iodine) can delay cord separation and the absorbed iodine may interfere with the newborn's thyroid function.
Option C: Mercurochrome is an obsolete antiseptic containing mercury and is no longer used due to the significant risk of mercury toxicity in newborns.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Neonatal Umbilical Cord Care as background academic context rather than a clinical decision trigger.
Nurses are responsible for educating new parents on current best practices for cord care, explaining the rationale for dry care over older, antiseptic-based methods.
A key nursing role is teaching parents to recognize and report signs of omphalitis (cord infection), such as redness spreading to the abdomen, pus, foul odor, or fever, which requires immediate medical attention.
What if? If a baby is born in a low-resource setting with poor hygiene and a high rate of neonatal infections, the World Health Organization (WHO) may recommend daily application of 4% chlorhexidine to the cord stump to prevent sepsis.

How to Approach the Question

Identify the core question: What is the current recommended practice for routine umbilical cord care at birth?
This is a factual recall question based on clinical guidelines. Access your knowledge of standard neonatal nursing procedures.
Evaluate the options. Recognize that 'Potassium permanganate,' 'Betadine,' and 'Mercurochrome' are all antiseptics or chemical agents.
Recall that modern, evidence-based practice has moved away from routine application of substances to the cord.
Select 'Nothing' as it represents the principle of 'dry cord care,' which is the current standard in most settings to promote natural healing and prevent chemical irritation.
Confirm by eliminating the other options based on their known risks: irritation (Potassium permanganate), thyroid effects (Betadine), and toxicity (Mercurochrome).
