24 Case Scenario & Prioritization BK is post-op Bilroth I and is to receive 2 units of blood. As you get out of report, lab calls and says the first unit of blood is ready. Prioritize:Verify order to transfuse blood and consentTake initial set VSPick up blood from labAssess IV siteStart transfusionVerify pt ID, & blood compatability
25 PrioritizationPre-transfusion T98.6, P80, R18, BP136/78. Transfusion started, slow …..15 minutes later- T98.2, P90, R22, BP 130/70, no itching, rate increased 100/h……20 minutes later- skin flushed, p 120, R32, BP100/60, c/o chest pain & chills.Priority problem???
