Which is a common finding seen in dengue patients, except?

Appeared in: AIIMS Delhi NO - 2017

Explanation

Neutropenia (a low count of neutrophils) is not considered a hallmark or classic finding in dengue fever, unlike the other options provided.
While a general decrease in the total white blood cell count (leukopenia) is a common finding, a specific and significant drop in neutrophils is less characteristic of the typical disease course.
Sources indicate that neutropenia may appear in the later stages of the disease but is not as consistently present as high fever, severe joint pain, and thrombocytopenia.

Option A: This is a very common finding. Severe joint pain (arthralgia) and muscle pain (myalgia) are so characteristic that dengue is colloquially known as 'breakbone fever'.
Option B: This is a very common finding. Thrombocytopenia (a platelet count below 100,000/μL) is a classic laboratory finding in dengue and a key criterion for diagnosing Dengue Hemorrhagic Fever (DHF).
Option D: This is a very common finding. A sudden onset of high-grade fever is one of the most prominent and initial symptoms of dengue fever.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Clinical Manifestations of Dengue Fever as background academic context rather than a clinical decision trigger.
Nurses must be vigilant in monitoring patients with suspected dengue for the classic signs: fever, severe pain, and rash.
A critical nursing responsibility is monitoring the complete blood count (CBC), with special attention to the platelet count. A rapid drop in platelets can signal progression to severe dengue (Dengue Hemorrhagic Fever/Dengue Shock Syndrome), which is a medical emergency.
Patient education is key. Nurses should advise patients on supportive care, such as hydration and rest, and to avoid non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin, which can increase bleeding risk.

How to Approach the Question

First, identify the core of the question. It asks to find the feature that is an 'exception' among common findings in dengue.
This means you need to identify three options that are indeed common in dengue.
Recall or look for the classic signs and symptoms of dengue. Think of the term 'breakbone fever,' which points to severe pain (Joint pain).
Remember the hallmark laboratory findings. High fever and low platelets (Thrombocytopenia) are classic.
Evaluate the remaining option, 'Neutropenia.' While leukopenia (low total WBC) is common, consider if neutropenia (low neutrophils specifically) is as defining as the other three.
By confirming that fever, joint pain, and thrombocytopenia are classic features, you can confidently select neutropenia as the exception.
