Final answer:
In heparin-induced thrombocytopenia (HIT), a decreased erythrocyte count would be expected.
Step-by-step explanation:
In a patient who develops heparin-induced thrombocytopenia (HIT), the laboratory result that the nurse would expect to show a decreased value is b. Erythrocyte count. Heparin-induced thrombocytopenia is a condition where the body forms antibodies against platelet factor 4 (PF4) that is bound to heparin. These antibodies can lead to platelet destruction and a decrease in the number of erythrocytes (red blood cells) in the circulation.
