Thrombocytopenia means -?

Appeared in: MP CHO - 2022

Explanation

Thrombocytopenia is the medical term for a platelet count below the normal range.
The term is derived from 'thrombocyte' (platelet) and '-penia' (deficiency).
A normal platelet count is between 150,000 and 450,000 platelets/µL.
Low platelet levels lead to impaired blood clotting and an increased risk of bleeding.

Option A: Thrombosis is the formation of a blood clot, which is a separate pathological process. Thrombocytopenia is a deficiency in the cells that help form clots.
Option C: Hypercoagulopathy describes a state of increased tendency to form blood clots. Thrombocytopenia causes a bleeding tendency, which is the opposite.
Option D: A high platelet count is known as thrombocytosis or thrombocythemia. Thrombocytopenia is defined by a low count.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition of Thrombocytopenia as background academic context rather than a clinical decision trigger.
Nurses must implement bleeding precautions for any patient with a platelet count below 50,000/µL to prevent injury and life-threatening hemorrhage.
Patient education is a key nursing role, involving teaching the patient and family to recognize signs of bleeding and to avoid activities and medications (like NSAIDs) that increase bleeding risk.
What if? If a patient with severe thrombocytopenia (e.g., count of 15,000/µL) develops a severe headache, the nurse must immediately suspect an intracranial hemorrhage and escalate care for an urgent neurological assessment and CT scan.

How to Approach the Question

This is a direct recall question testing medical terminology.
First, break down the term 'Thrombocytopenia'.
Recognize the prefix 'Thrombo-' refers to thrombocytes, or platelets.
Recognize the suffix '-penia' means deficiency or a lack of something.
Combine the parts: 'Thrombocytopenia' means a deficiency of platelets.
Scan the options to find the one that matches this definition, which is 'Low platelet count'.
