The nurse examines a client's auditory canal and tympanic membrane with an otoscope. The nurse recognizes that which of the following is considered an abnormal finding?
A shiny, pearly white color tympanic membrane
The presence of cerumen
The presence of a cone of light
A yellow or amber color to the tympanic membrane.
The Correct Answer is D
A. A shiny, pearly white color tympanic membrane: This is a normal finding. A healthy tympanic membrane often appears shiny and pearly white.
B. The presence of cerumen: This is a normal finding. Cerumen, or earwax, is a natural substance that helps protect the ear canal.
C. The presence of a cone of light: This is a normal finding. The cone of light is a reflection of the otoscope light on the tympanic membrane and is a normal variation.
D. A yellow or amber color to the tympanic membrane: This is considered an abnormal finding. A yellow or amber coloration of the tympanic membrane can indicate the presence of fluid or infection behind the eardrum, which may be a sign of otitis media or other ear conditions.

Correct Answer is C
Explanation
A. VI
Cranial Nerve VI is the Abducent Nerve, which controls the movement of the lateral rectus muscle, allowing the eye to move laterally (abduct). Dysfunction of this nerve can cause difficulty in moving the eye outward.
B. V
Cranial Nerve V is the Trigeminal Nerve. It has both sensory and motor functions. Sensory functions include providing sensation to the face, sinuses, and teeth. Motor functions include controlling the muscles used for chewing (mastication).
C. II
Cranial Nerve II is the Optic Nerve. It is purely a sensory nerve responsible for vision. The optic nerve carries visual information from the retina of the eye to the brain.
D. III
Cranial Nerve III is the Oculomotor Nerve. It is primarily a motor nerve but also has some autonomic functions. It controls most of the eye movements (except lateral movement controlled by VI) and regulates the size of the pupil and the shape of the lens in the eye for focusing.
Correct Answer is A
Explanation
A. AV node - SA node - bundle of His - bundle branches:
This sequence is incorrect. The SA node (sinoatrial node) initiates the electrical impulse in the heart, followed by the AV node (atrioventricular node), bundle of His, and then the bundle branches.
B. SA node - AV node - bundle of His - bundle branches:
This sequence is correct. The electrical stimulus of the cardiac cycle starts at the SA node, which is the natural pacemaker of the heart. From the SA node, the impulse travels to the AV node, then to the bundle of His, and finally to the bundle branches, which distribute the impulse to the ventricles, causing them to contract.
C. Bundle of His - AV node - SA node - Erb's Point:
This sequence is incorrect. Erb's Point is a point on the chest where heart sounds S2 and S3 can be heard most distinctly.
D. AV node - SA node - bundle of His - Erb's Point:
This sequence is incorrect. The AV node comes after the SA node in the electrical conduction system of the heart. Erb's Point is not a part of the normal cardiac conduction pathway; it is a location for auscultation on the chest.
