The patient suddenly feels lightheaded, dizzy and weak. You assist the patient to bed and notify the doctor.  Vitals Blood pressure 76/38 mmHg, temperature 98.6F, respirations 18 breaths/min and pulse ox 95% on room air.   The doctors orders and EKG and the following rhythm is revealed:    Based off the EKG strip, the nurse knows that the patient is in which of the following heart rhythms?

The following laboratory results were obtained on a mother and her baby immediately following delivery of the neonate.  Examine the medical history and test results provided below to determine the MOST probable cause of HDFN?                  Mother:           O D Positive Antibody detection/screen results shown below. Cell I.S (Room Temp.) (PEG) AHG IgG-coated RBCs (Pcells) I 0 3+ TNP II 0 3+ TNP III 0 0 P                              TNP: Test Not Performed               Baby:              O D Positive                                     DAT: Positive (2+)                                     Hgb: 11.0 g/dL                                     HCT: 33%                                     Bilirubin: Total 5.6 mg/dL; Direct 1.2 mg/dL

Explain how you know that the correct antibodies have been identified. Include how the “Rule of 3” applies as well as calculated p-values in your explanation.  Students don’t need to show calculation but refer to the p-value in your answer.

A forty-eight year old female is undergoing chemotherapy for lung cancer. She is scheduled to receive two units of RBCs in the oncology clinic today.  While receiving her first unit of RBCs she begins to complain of intense pain at the site of infusion. The transfusion is immediately stopped and the blood bank is alerted of a suspected transfusion reaction.  Upon investigation it is noted that the patient is in shock and her temperature rose from 98.4oF to 102.8oF.  She is in DIC and renal failure, with large amounts of hemoglobin in her urine. Her DAT is negative at this time.  This patient is most likely experiencing what type of transfusion reaction?
