Question 3

A patient's blood sample shows hemolysis. Which of the following could be a cause?

Accepted Answer

Using a small-gauge needle with a syringe

Answer

Using a small-gauge needle with a syringe can cause hemolysis because the narrow lumen creates shear forces that rupture red blood cells.

Question 4

Where is the preferred site for a heelstick procedure in newborns?

Accepted Answer

Lateral or medial plantar surface of the heel

Answer

The lateral or medial plantar surface of the heel is preferred for heelsticks because it avoids bone, nerves, and major blood vessels.

Question 5

What should be done if a patient faints (syncope) during a blood draw?

Accepted Answer

Remove the needle, apply pressure, and lower the patient's head

Answer

The needle must be removed immediately to prevent injury, pressure applied to stop bleeding, and the patient's head lowered to restore cerebral blood flow.
