🩸 Hematological System Disorder

Let’s understand this in a very simple way.

What is the hematological system?
The hematological system refers to the body’s blood and blood-forming organs.

It includes:

• Red blood cells (RBCs)
• White blood cells (WBCs)
• Platelets
• Bone marrow

Which condition directly indicates a hematological problem?

✅ Correct Answer: (b) Polycythemia vera

What is Polycythemia Vera?
Polycythemia vera is a blood disorder in which the bone marrow produces too many red blood cells.

👉 This makes the blood thicker and increases the risk of:

• Blood clots
• Stroke
• Heart attack

Because it is a disorder of blood cell production, it is a hematological disease.

Why other options are not correct?

• (a) Jaundice → ❌ A sign/symptom, usually related to liver disease or increased bilirubin
• (c) Gout → ❌ A metabolic disorder caused by uric acid accumulation
• (d) Renal calculi → ❌ Kidney stones, related to the urinary system

Important Nursing Point:
The word “poly” means many and “cythemia” refers to blood cells. Therefore, polycythemia vera means an abnormal increase in blood cells, especially RBCs.

Simple Exam Trick:
Blood disorder + Excess RBC production → Polycythemia Vera

📌 Disclaimer: For exam preparation only. Follow hematology references and clinical guidelines in practice.
