Which vein is the preferred first-choice site for venipuncture in the antecubital fossa?
Answer: Median cubital vein
The median cubital vein is the preferred first-choice venipuncture site because it is large, well-anchored, and poses less risk of arterial puncture.
What is the function of erythrocytes in the blood?
Answer: Transport oxygen and carbon dioxide
Erythrocytes (red blood cells) contain hemoglobin, which carries oxygen to tissues and carbon dioxide back to the lungs.
Which layer of the skin contains blood vessels and nerves relevant to venipuncture depth?
Answer: Dermis
The dermis contains blood vessels, nerve endings, and connective tissue, making it the layer most relevant to needle depth during venipuncture.
The antecubital fossa is located at which anatomical position?
Answer: Inner aspect of the elbow
The antecubital fossa is the triangular depression on the anterior (inner) surface of the elbow, housing the primary venipuncture veins.
Which blood component is primarily responsible for hemostasis and forming a platelet plug?
Answer: Thrombocytes
Thrombocytes (platelets) aggregate at the site of vessel injury to form a platelet plug, initiating the hemostasis process.
What is the normal adult range for hemoglobin in a male patient?
Answer: 13.5–17.5 g/dL
The normal hemoglobin range for adult males is approximately 13.5–17.5 g/dL, reflecting adequate red blood cell oxygen-carrying capacity.
