Review Question - QID 108688

A 69-year-old male with a past medical history of hypertension, hyperlipidemia, and diabetes mellitus complicated by end-stage renal disease on dialysis presents to his nephrologist for a follow-up appointment. A few weeks ago, the patient saw his nephrologist because he had been feeling tired despite efforts to get enough sleep, eat a well-balanced diet, and exercise. At the time, laboratory studies revealed a hemoglobin of 9.7 g/dL so the patient was started on recombinant human erythropoietin (EPO). Since then, the patient has been receiving EPO intravenously 3 times per week. The patient reports today that he continues to feel tired despite the new treatment. His temperature is 98.0°F (36.7°C), blood pressure is 134/83 mmHg, pulse is 65/min, and respirations are 12/min. On physical exam, he has conjunctival pallor, and laboratory studies show a hemoglobin of 9.8 g/dL. Which of the following sets of laboratory findings shown in Figure A would currently be seen in this patient?
