Case Study No. 1 It’s the third day on the job for Maria Hernandez. She consults her requisition for the next patient and sees that he needs a coagulation test. Maria assembles her materials, including a tourniquet, swabs, bandage, and a lavender tube. She enters the patient’s room, asks him to state his name, checks on the wrist band, and proceeds with the draw. Afterward, she labels the tube, makes sure the bleeding has stopped, and thanks to the patient as she leaves. But as she closes the door, she stops a look of panic on her face.

1. What did she do wrong? (Explain in 10 sentences)

2. What should she do now? (Explain in 10 sentences)

Case Study No. 2 You are performing the last draw of your shift. It’s been a long day and you are looking forward to meeting your friends for pizza right after work. The patient is prepped, the tourniquet is on, and you reached for the red-topped tube which is the last one on your tray. As you are about to insert the multi-sample needle into the tube, you noticed the expiration date – it just expired.

Should you go ahead and perform the draw anyway since the tube contains no additives that might go bad over time and the vacuum is almost certainly still good? Or should you stop the draw and ask the patient to wait while you get another tube? (Explain elaborately and comprehensively in 20 sentences)

2)it will lead to incompatible blood transfusion reactions

4)the physician wrongly diagnosing a disease.

5)medical procedures and surgeries being performed on the wrong patinet
