Blood sampling technique, use of safety devices, disposal methods, reuse of devices and availability of hepatitis b vaccine 3. What should be observed at all times for the protection of the patient and the healthcare worker? Universal precautions 4. List 15 complications which can arise as a complication from venipuncture. Hematoma, infections, nerve damage, hemoconcentration extravasations, fainting, petechiae, excessive bleeding, edema, fear and phobia, thrombosis, arterial puncture, pain, allergies, and Iatrogenic anemia.

What is the ideal time for blood specimens to be collected? A. At midnight B. 6 hours after the last ingestion of food C. 12 hours after the last ingestion of food D. 24 hours after the last ingestion of food 3.

D. the patient must rest for at least 13 hours and not drink water or eat any food. 7. Which of the following should stop the health care worker from collecting blood from a patient’s arm vein? A.

What is the effect on a patient if a phlebotomist punctures a nerve with the blood collection needle? A. It should not have an effect on the patient or blood specimen. B. The patient will feel a sharp radiating pain and the procedure should be discontinued. C. The blood specimen may be contaminated with interstitial fluid. D. The patient’s arm may tingle slightly but it should not interfere with the rest of the procedure. 10. A hemolyzed specimen can lead to falsely increased results for: A. RBC count. B. Hematocrit. C.
