Final answer:
The urinalysis (UA) may reveal proteinuria and haematuria, while a blood smear may show hemoglobinuria.
Step-by-step explanation:
When a patient with scleroderma presents with acute renal failure and malignant HTN, the urinalysis (UA) and blood smear may show certain findings. UA may reveal abnormalities such as proteinuria (abnormal protein levels in the urine) and haematuria (presence of red blood cells in the urine), which can be observed in conditions like nephritis, trauma, tuberculosis of the kidney, and kidney stones. A blood smear may show hemoglobinuria (excess hemoglobin in the urine), which can be seen in conditions like malaria, kala-azar, and typhoid.
