Question 1

A specimen collector notes that a patient's veins are not visible or palpable in the antecubital area. Which alternative site on the forearm is the next best option?

Accepted Answer

Dorsal hand veins

Answer

Dorsal hand veins are the next acceptable alternative when antecubital veins are inaccessible, though they require smaller gauge needles.

Question 2

Which component of whole blood is responsible for oxygen transport throughout the body?

Accepted Answer

Erythrocytes

Answer

Erythrocytes (red blood cells) contain hemoglobin, which binds oxygen in the lungs and releases it to tissues throughout the body.

Question 3

The femoral artery runs through which region of the lower extremity and must be avoided during routine blood collection?

Accepted Answer

Femoral triangle

Answer

The femoral artery passes through the femoral triangle in the upper inner thigh; accidental arterial puncture here can cause serious hemorrhage.

Question 4

Which organ produces bile that is stored in the gallbladder and released to emulsify dietary fats in the duodenum?

Accepted Answer

Liver

Answer

The liver continuously produces bile, which is stored in the gallbladder and secreted into the duodenum when fatty food enters the small intestine.

Question 5

When performing a heel stick on a newborn, the maximum recommended puncture depth is 2.0 mm to avoid injuring which underlying structure?

Accepted Answer

Calcaneus (heel bone)

Answer

Puncturing deeper than 2.0 mm risks striking the calcaneus (heel bone), potentially causing osteomyelitis or osteochondritis in neonates.
