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 D
Explanation
A. Indicates the beginning of diastole: This statement is not accurate. S2, the second heart sound, indicates the end of systole and the beginning of diastole. It is specifically associated with the closure of the aortic and pulmonary valves.
B. Coincides with the carotid artery pulse: This statement is not accurate. S2 is associated with the closure of the aortic and pulmonary valves in the heart, not with the carotid artery pulse.
C. Is louder than an S1: This statement is not accurate. S1, the first heart sound, is usually louder than S2. S1 is associated with the closure of the mitral and tricuspid valves and marks the beginning of systole.
D. Is caused by the closure of the semilunar valves: This statement is accurate. S2 is caused by the closure of the aortic and pulmonary valves, which are the semilunar valves in the heart. It marks the end of systole and the beginning of diastole.
