Review Question - QID 212530

A 68-year-old man of Mediterranean descent comes to the clinic with complaints of fatigue for the past month. He reports that it is increasingly difficult for him to complete his after-dinner walks as he would get breathless and tired around 10 minutes. He endorses dizziness and an upper respiratory infection last week for which he “took a lot of aspirin.” Past medical history is significant for malaria 10 years ago (for which he was adequately treated with anti-malarial medications) and aortic stenosis status post prosthetic valve replacement 5 months ago. When asked if he has had similar episodes before, he claims, “Never! I’ve been as healthy as a horse until my heart surgery.” Physical examination is significant for mild scleral icterus bilaterally and a faint systolic murmur. Which of the following images represents a potential peripheral smear in this patient?
