infection is the leading cause of death in these patients.
the immunosuppression involves a single element or process
immune incompetence is symptomatic even without pathogen exposure.
A patient with a history of pulmonary embolism is being worked up for a potential coagulopathy that increases the risk for clotting. The nurse understands that the provider may request a test for

The patient is admitted with anemia caused by blood loss and thrombocytopenia and has a platelet count of 22,000/microliter. The patient is scheduled for a transfusion of RBCs and a transfusion of platelets. The nurse should
