Final answer:
Increased hemoglobin concentration, leukocytosis, and thrombocytosis suggest the disease polycythemia vera, a condition that leads to high blood viscosity and is more common in the elderly.
Step-by-step explanation:
The disease suggested by an increased hemoglobin concentration, leukocytosis (an increase in white blood cell count), and thrombocytosis (an elevated platelet count) is polycythemia vera. This condition involves an overproduction of red blood cells (RBCs) and often results in increased levels of white blood cells and platelets as well. Polycythemia vera can lead to increased blood viscosity, making it more difficult for the heart to pump blood, potentially raising blood pressure and causing various health issues. It is not typically associated with dehydration, living at high altitudes, or a direct consequence of pulmonary disease. The characteristics mentioned align well with the bone marrow disease called polycythemia vera, making option 3 the correct answer to the question. The condition is more common in older individuals over the age of 60 and is considered a rare disease.
