The nurse is performing the diagnostic positions test. The nurse recognizes that normal findings from the diagnostic positions test should be which of these results?
Nystagmus in extreme superior gaze
Slight amount of lid lag when moving the eyes from a superior to an inferior position
Parallel movement of both eyes
Convergence of the eyes
The Correct Answer is C
A. Nystagmus in extreme superior gaze: Nystagmus is an involuntary eye movement and is not a normal finding, especially in extreme superior gaze. Nystagmus can be indicative of neurological issues and requires further evaluation.
B. Slight amount of lid lag when moving the eyes from a superior to an inferior position: Lid lag refers to a delay in the downward movement of the upper eyelid during eye movement. This can be a sign of hyperthyroidism and is not a normal finding.
C. Parallel movement of both eyes: This is the correct answer. During the diagnostic positions test, the nurse should observe parallel movement of both eyes in all directions, indicating normal extraocular muscle function and coordination.
D. Convergence of the eyes: Convergence refers to the inward movement of both eyes when focusing on a close object. While convergence is a normal phenomenon, it is not specifically assessed during the diagnostic positions test, which primarily evaluates the range of motion and coordination of the extraocular muscles.

Correct Answer is B
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.
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.
