Explanation

Omphalitis is the medical term for an infection of the umbilical cord stump and/or the surrounding tissues in a newborn.
The name is derived from 'omphalos,' the Greek word for navel, and the suffix '-itis,' which means inflammation or infection.
The devitalized (dead) tissue of the cord stump after birth provides an ideal environment for bacterial growth, making it a potential portal of entry for microbes.
Common causative bacteria include Staphylococcus aureus and Escherichia coli.

Option B: An infection of the ears is known as otitis (e.g., otitis media for the middle ear, otitis externa for the outer ear canal), not omphalitis.
Option C: An infection of the pharynx (the part of the throat behind the mouth and nasal cavity) is called pharyngitis, commonly known as a sore throat.
Option D: This is a duplicate of the second option. An infection of the ears is called otitis, not omphalitis.

Clinical Relevance

Nursing practice connection: Knowing Neonatal Infections and Umbilical Cord Care helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
A primary nursing role is educating new parents on proper umbilical cord care, which is the most effective way to prevent omphalitis.
Nurses must perform and teach diligent assessment for early signs of infection, as omphalitis can rapidly progress to life-threatening systemic infection (sepsis), necrotizing fasciitis, or portal vein thrombosis.
What if? If a parent calls reporting redness just at the base of the cord that is less than 1 cm wide, with no pus, fever, or other systemic signs, the nurse might advise continued close monitoring and reinforcing clean, dry cord care. However, they should also instruct the parent to seek immediate medical evaluation if the redness spreads or any other signs of illness appear.

How to Approach the Question

This is a factual recall question that tests your knowledge of medical terminology.
First, analyze the term 'Omphalitis'. Break it down into its roots: the prefix 'omphal-' refers to the umbilicus or navel, and the suffix '-itis' means inflammation or infection.
Combine the meanings: 'Omphalitis' means infection of the umbilicus (navel).
Next, evaluate the given options to find the one that matches this definition.
Option A, 'Umbilical cord', is directly related to the umbilicus/navel in a newborn.
Eliminate the other options by recalling the correct terminology for their infections: 'otitis' for ears and 'pharyngitis' for the pharynx.
