What is the first stool of a newborn called?

Appeared in: Bihar CHO -2019

Explanation

Meconium is the medical term for the first feces of a newborn infant.
It is composed of materials ingested during the time the infant spends in the uterus: intestinal epithelial cells, lanugo, mucus, amniotic fluid, bile, and water.
Meconium is characteristically viscous and sticky like tar, and its color is usually a very dark olive green; it is almost odorless.
The passage of meconium within the first 24-48 hours is a key indicator of a patent and functional gastrointestinal tract.

Option A: Mallonium is not a recognized medical term. It is a distractor designed to sound similar to the correct term.
Option B: Melinium is not a recognized medical term. It is a distractor designed to sound similar to the correct term.
Option D: This option is incorrect because a correct answer, Meconium, is provided in the options.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain The first stool of a newborn as background academic context rather than a clinical decision trigger.
Assessing the first stool is a fundamental nursing responsibility in neonatal care. Failure to pass meconium within 48 hours is a critical finding that must be escalated to a provider, as it can signify serious conditions like Hirschsprung disease or meconium ileus (often associated with cystic fibrosis).
The color of the stool is also vital. While meconium is dark green-black, subsequent transitional stools become yellow. The appearance of pale or clay-colored stools is a major red flag for biliary atresia, a life-threatening liver condition requiring urgent surgical intervention.
What if? If a newborn passes a normal meconium stool but then develops forceful, projectile vomiting at 3 weeks of age, the priority concern shifts from bowel patency to a possible gastric outlet obstruction, such as pyloric stenosis.

How to Approach the Question

First, read the question carefully to identify the key subject: the name of a newborn's first stool.
Next, evaluate the options provided. Notice that 'Mallonium' and 'Melinium' sound phonetically similar to a known medical term but are likely distractors.
Recall or deduce the correct medical terminology for neonatal milestones. The term 'Meconium' is the specific name for the first stool.
Eliminate the incorrect options. 'Mallonium' and 'Melinium' are not real terms. 'None of these' is incorrect because 'Meconium' is a valid and correct option.
Confirm your choice. 'Meconium' is the standard term used in obstetrics and pediatrics for the first stool passed by a newborn.
