What is the approximate normal adult platelet count range?
Answer: 150,000–400,000 per µL
The normal adult platelet count is 150,000–400,000 per µL; counts below this range indicate thrombocytopenia and increased bleeding risk.
Which part of the circulatory system do veins belong to?
Answer: Venous (low-pressure) system
Veins belong to the venous (low-pressure) system, carrying blood back toward the heart under low pressure compared to arteries.
What does the hematocrit measurement represent?
Answer: Percentage of red blood cells in total blood volume
Hematocrit is the percentage of whole blood volume occupied by red blood cells, with normal adult male values around 41–53%.
Which nerve runs near the basilic vein in the antecubital area, making it a higher-risk venipuncture site?
Answer: Medial cutaneous nerve of the forearm
The medial cutaneous nerve of the forearm runs close to the basilic vein, increasing the risk of nerve injury if this vein is chosen for venipuncture.
What is the liquid portion of unclotted whole blood called?
Answer: Plasma
Plasma is the liquid portion of unclotted (anticoagulated) whole blood, containing clotting factors, proteins, and other dissolved substances.
What anatomical landmark is used to locate the femoral vein for blood collection?
Answer: Medial to the femoral artery in the groin
The femoral vein lies medial (toward midline) to the femoral artery in the femoral triangle of the groin, used only in emergency collections.
