If after administering a vaccine the needle safety mechanism fails, what should you do?

For Questions 1-4, watch and listen carefully to the videos embedded into each question in order to determine the systolic and diastolic blood pressures for each patient. Document the systolic pressure in the first box and diastolic pressure in the second box beneath each video to answer each question.

Refer to the following results of the antibody screen and DAT tests: What is most likely presumption?   

Refer to the antibody panel results below.  The patient is from out of town.  There is no previous history on file at this hospital for this patient.  What is the most probable conclusion?

Which of the following antibodies in the Lutheran system is most likely to be IgM and detected as a direct agglutinin?

The purpose of the immediate spin crossmatch is to detect incompatibility with:

Refer to the antigram below to answer the question.  RB is a 65-year-old Caucasian male with group O Rh(D)-negative phenotype. Upon review, there is a prior history of transfusion ten years ago. The pretransfusion 2-cell screen was negative using LISS. Group O Rh(D)-negative units were compatible when crossmatched at immediate spin and were released. RB was transfused with two units of RBCs during hip-replacement surgery.  One day following surgery, a delayed transfusion reaction was suspected because of a drop in hemoglobin. A transfusion reaction workup was requested. The pre- and post-samples were compared visually for hemolysis. The DAT on the post-reaction sample was microscopic positive.  The posttransfusion antibody screen was 2+ positive with one of the screening cells (using LISS) at AHG. An antibody identification panel was performed. What is the most likely antibody?  (Tip:  Do not get lost in the case history.  Focus on solving the antigram.  You got this!)
