Appeared in: AIIMS Delhi NO - 2018
Explanation
- The image clearly shows an otoscope, a handheld device specifically designed for the visual examination of the ear.
- The instrument is being used to inspect the external auditory canal and the tympanic membrane (eardrum), which is the primary function of an otoscope.
- The key components visible in the image—the handle, the head containing a light and magnifying lens, and a disposable speculum—are all characteristic features of an otoscope.
Why Other Options Were Wrong
- Option B: An ophthalmoscope is used to examine the internal structures of the eye, such as the retina, optic disc, and blood vessels.
- Option C: A gastroscope is a type of flexible endoscope that is passed through the mouth to visualize the esophagus, stomach, and duodenum.
- Option D: A bronchoscope is a flexible endoscope inserted through the nose or mouth to examine the trachea and bronchi (the airways of the lungs).

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification and purpose of common medical diagnostic instruments as background academic context rather than a clinical decision trigger.
- Nurses frequently use otoscopes in primary care, pediatrics, and emergency settings to perform initial assessments for patients presenting with ear pain, hearing loss, or suspected infection.
- Proper technique is crucial for patient safety and comfort. This includes selecting the correct size speculum and gently pulling the pinna to straighten the ear canal (up and back for adults; down and back for children under 3).
- What if? If the patient were a child under 3 years old, the nurse would need to pull the pinna down and back to straighten the ear canal for proper visualization, as opposed to up and back for an adult.
How to Approach the Question
- First, carefully analyze the image provided. Observe the instrument being used and the part of the body it is being used on.
- Identify the key features of the instrument: it is handheld, has a handle, and a cone-shaped tip (speculum) being inserted into the patient's ear.
- Recognize this instrument as an otoscope, which is specifically designed for ear examinations.
- Read the question, which asks to identify the instrument and its function.
- Evaluate the given options. Option A correctly pairs the body part ('Ear') with the instrument's name ('Otoscope').
- Systematically eliminate the other options by recalling the functions of the other instruments: an ophthalmoscope is for the eye, a gastroscope for the stomach, and a bronchoscope for the lungs.
