Question

A synovial fluid specimen has a high cell count and requires dilution to be counted. Which of the following diluents should be used? A. Normal saline B. Dilute acetic acid (2%) C. Dilute methanol (1%) D. Phosphate buffer solution (0.050 mol/L)

Answer 1

A NORMAL SALINE

Step-by-step explanation:

A synovial fluid specimen has a high cell count and requires dilution to be counted. Which of the following diluents should be used? A. Normal saline B. Dilute acetic acid (e.g., a 2% solution) C. Dilute methanol (e.g., a 1% solution) D. Phosphate buffer solution (e.g., 0.050 mol L)

A. Normal saline

When counting cells in a synovial fluid specimen, think of it like counting people in a crowded room - you need to dilute the fluid with normal saline to make it easier to count the cells.
