Which of the following is NOT a symptom of measles?

Appeared in: NHM UP Staff Nurse-2023 shift 1st

Explanation

Vernix caseosa is a waxy, cheese-like white substance that naturally coats the skin of newborn babies.
It is a completely normal physiological finding and serves to protect the infant's skin in the uterus and moisturize it after birth.
This substance is not a sign or symptom of any infectious disease, including measles.

Option A: High fever is a hallmark symptom of measles, typically appearing during the prodromal phase about 10 days after exposure.
Option B: Conjunctivitis (red, watery eyes) is one of the classic '3 Cs' of measles, along with cough and coryza.
Option C: Coryza (a runny nose) is another of the classic '3 Cs' that characterize the early stage of measles.

Clinical Relevance

Nursing practice connection: Knowing Identification of measles symptoms and differentiation from unrelated physiological findings helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Recognizing the classic triad of cough, coryza, and conjunctivitis, along with fever, is crucial for early suspicion of measles, enabling prompt isolation and public health notification to prevent outbreaks.
Nurses must be able to differentiate disease symptoms from normal physiological findings like vernix caseosa to provide appropriate care, reassure parents, and avoid unnecessary anxiety or interventions.
What if? If a child presented with a high fever that subsides just as a rash appears (exanthem subitum), the diagnosis would more likely be Roseola Infantum, not measles. The timing of the rash relative to the fever is a key differentiator.

How to Approach the Question

First, identify the core subject of the question, which is the symptoms of measles (Rubeola).
Note the negative keyword 'NOT'. This signals that you must find the option that is an outlier or does not belong with the others.
Recall the classic symptoms of measles, often remembered by the '3 Cs': Cough, Coryza (runny nose), and Conjunctivitis (red eyes). High fever is also a primary symptom.
Systematically evaluate each option against this knowledge.
Option A (High fever), B (Conjunctivitis), and C (Coryza) are all well-known, characteristic symptoms of measles.
Option D (Vernix caseosa) refers to the waxy coating on a newborn. This is a term from obstetrics/neonatology and is unrelated to infectious diseases.

Concept Tested & Keywords

Concept Tested: Identification of measles symptoms and differentiation from unrelated physiological findings.
Stem keywords: symptom, measles
Lead-in keywords: NOT
Negative lead-in flag: The question uses negative framing ('NOT'), asking to identify the option that is an exception.
