Question

multiple select question
select all that apply
choose all that would directly reduce blood viscosity.

□ protein deficiency

□ dehydration

☑ decreased hematocrit

□ increased platelet production

Explanation:

• Protein deficiency: Plasma proteins (like albumin) affect blood viscosity. Deficiency reduces protein concentration, lowering viscosity.
• Dehydration: Increases blood viscosity (more concentrated), so it does not reduce.
• Decreased hematocrit: Hematocrit is the volume of red blood cells. Fewer red blood cells mean less "thickness," so viscosity decreases.
• Increased platelet production: Platelets contribute to blood clotting but not directly to viscosity reduction (and more platelets might increase clotting risk, not reduce viscosity). So the correct options are Protein deficiency and Decreased hematocrit.

Answer:

A. Protein deficiency, C. Decreased hematocrit
