Answer

Consistent hydration levels

Answer

Stable metabolic rate

Answer

Fixed dietary intake

Question 5

In which clinical scenario is an elevated mean platelet volume (MPV) most concerning?

Accepted Answer

Answer

Pioglitazone therapy

Answer

Routine health screening

Answer

Viral infections

Question 6

How does mean platelet volume (MPV) differ in patients with thrombocytopenia compared to healthy individuals?

Accepted Answer

MPV may be increased due to a compensatory mechanism

Answer

MPV always decreases

Answer

MPV remains unchanged

Answer

MPV is not measured in thrombocytopenia
