Answer:
d. Small aperture
Step-by-step explanation:
When examining a patient with a suspected retinal hemorrhage, the small aperture on the ophthalmoscope is the most appropriate choice. The small aperture provides a focused and narrow beam of light, which is helpful for assessing fine details of the retina, including small hemorrhages. This allows for better visualization and assessment of the retina in cases where there may be retinal pathology, such as a hemorrhage.
