Answer to Question 1

ANS: D
Decreasing the angle of the spreader slide will make the blood film thinner, as well as longer.

Answer to Question 2

ANS: B
When platelet clumping repeatedly occurs in an EDTA blood, the blood should be drawn in a sodium citrate tube. The dilution of blood by the anticoagulant is 9:10 (9 parts blood to 1 part anticoagulant). The platelet count obtained on this tube must therefore be multiplied by the reciprocal of the dilution (10/9) = 1.1.
