A) A normal-sized red blood cell B) A red blood cell with an abnormal shape C) A large red blood cell measuring over 8 µm in diameter D) A small red blood cell
Understand the Problem
The question is asking for the definition of a macrocyte and provides multiple choice options to identify its characteristics, specifically its size and shape in relation to red blood cells.
Answer
A large red blood cell measuring over 8 µm in diameter.
The final answer is C) A large red blood cell measuring over 8 µm in diameter.
Answer for screen readers
The final answer is C) A large red blood cell measuring over 8 µm in diameter.
More Information
Macrocytes are larger than normal red blood cells, typically defined as having a diameter greater than 8 µm. This condition is known as macrocytosis and can be identified in blood tests measuring the mean cell volume.
Tips
None of the other options (A, B, or D) correctly describe the term 'macrocyte'. A macrocyte is defined by its large size, not by its shape or being normal.
