Clinical Medical Assistant Certification Exam Practice Question
Which of the following medical instruments Is used to examine the retina?
Correct Answer: A
Rationale: The ophthalmoscope is specifically designed to examine the retina, allowing healthcare professionals to view the back of the eye, including the optic nerve and blood vessels. The otoscope is used for examining the ear canal and eardrum, making it unsuitable for retinal examination. A penlight serves to illuminate areas but does not provide the magnification or specialized optics needed for retinal assessment. The spirometer measures lung function and is unrelated to eye examinations, while the tonometer measures intraocular pressure, primarily for glaucoma screening, not direct retinal observation.
