A nurse suspects that a client may have aplastic anemia based on clinical manifestations and assessment. Which one of the following lab results would be consistent with this diagnosis?

Reasoning:

Choice A reason: A hemoglobin level of 15 g/dL is within the normal range and not consistent with aplastic anemia, which causes pancytopenia, including low hemoglobin due to bone marrow failure. Normal hemoglobin suggests adequate red blood cell production, ruling out aplastic anemia as the primary diagnosis.

Choice B reason: A platelet level of 275,000/mm3 is normal and does not support aplastic anemia, which involves bone marrow failure, leading to thrombocytopenia (low platelets). Normal platelet counts indicate intact megakaryocyte function, inconsistent with the pancytopenia characteristic of aplastic anemia’s bone marrow suppression.

Choice C reason: A white blood cell count of 1100 cells/mm3 indicates leukopenia, a hallmark of aplastic anemia. Bone marrow failure reduces production of all blood cell lines, including leukocytes, leading to low white cell counts, increasing infection risk, and supporting the diagnosis of aplastic anemia in this context.

Choice D reason: An erythrocyte count of 5.1 cells/mL is normal and not indicative of aplastic anemia, which causes anemia through reduced red blood cell production. Normal erythrocyte counts suggest preserved erythropoiesis, which is inconsistent with the pancytopenia expected in aplastic anemia’s bone marrow failure.

Reasoning:

Choice A reason: Systolic blood pressure above 70 mm Hg is a goal in hypovolemia but is not the most specific outcome for DIC-related bleeding. While low blood pressure reflects fluid loss, addressing bleeding directly prevents further volume depletion, making reduced bleeding a more targeted and measurable outcome.

Choice B reason: A stable level of consciousness is important but not directly tied to deficient fluid volume from bleeding in DIC. Altered consciousness may result from cerebral ischemia or hyponatremia, but reducing bleeding is the primary goal to stabilize fluid volume and prevent further hemodynamic compromise.

Choice C reason: Urine output of 30 mL/hour or more indicates adequate renal perfusion but is a secondary outcome in DIC-related bleeding. While it reflects fluid status, directly addressing bleeding through interventions like transfusions or clotting factor replacement is more specific to correcting the underlying fluid volume deficit.

Choice D reason: Decreased bleeding is the most appropriate outcome for deficient fluid volume in DIC, as bleeding from mucosal and venipuncture sites directly causes volume loss. Reducing hemorrhage through platelet or factor replacement stabilizes fluid volume, preventing hypovolemia and its complications, making this the most measurable and relevant outcome.
