A nurse is performing the diagnostic positions test. The nurse recognizes that normal findings from the diagnostic positions test should be which of these results?
Lid lag when moving the eyes from a superior to an inferior position
Nystagmus when reading the Snellen chart
Parallel movement of both eyes
Convergence of the eyes
The Correct Answer is C
A) Lid lag when moving the eyes from a superior to an inferior position:
This is incorrect. Lid lag refers to a delay in the movement of the eyelid as the eyes move downward. It is considered an abnormal finding and is often associated with conditions like hyperthyroidism (Graves' disease), where the eyelid does not follow the downward gaze appropriately. In the diagnostic positions test, normal eye movement should not include lid lag.
B) Nystagmus when reading the Snellen chart:
This is incorrect. Nystagmus is an involuntary, rhythmic oscillation of the eyes, which can be indicative of a neurological or vestibular issue. It is not a normal finding during the diagnostic positions test. Nystagmus may be seen with certain disorders, such as vestibular dysfunction, neurologic damage, or alcohol intoxication, but it should not occur as a normal response to eye movement during the diagnostic positions test.
C) Parallel movement of both eyes:
This is the correct answer. In a normal result of the diagnostic positions test, both eyes should move in parallel and remain aligned during all directions of gaze. The purpose of this test is to assess for any eye muscle weakness or cranial nerve dysfunction that might cause misalignment, such as strabismus or a disorder affecting the extraocular muscles. If both eyes track smoothly and simultaneously without deviation or lag, this is a normal and expected finding.
D) Convergence of the eyes:
This is incorrect. While convergence (the inward movement of both eyes toward the nose) is a normal response when focusing on a near object, it is not the specific goal of the diagnostic positions test. The diagnostic positions test is primarily concerned with assessing the ability of the eyes to move together in all directions of gaze without misalignment or abnormal movement. While convergence is a sign of normal eye function, it is not the primary focus of this particular test.

Correct Answer is A
Explanation
A) Palpate the chest symmetrically:
Palpating the chest symmetrically is crucial when assessing tactile fremitus, as it allows the nurse to compare the intensity of vibrations felt on both sides of the chest. Tactile fremitus refers to the palpable vibrations transmitted through the bronchopulmonary system when a person speaks or breathes. Symmetrical palpation ensures that the nurse can detect any differences in fremitus, which may indicate abnormalities such as lung consolidation (e.g., pneumonia), pleural effusion, or pneumothorax. Uneven fremitus can suggest a pathological condition, and symmetrical palpation helps identify these variations.
B) Ask the client to cough:
Asking the client to cough is not directly related to the assessment of tactile fremitus. Coughing may be used in other aspects of the respiratory assessment (e.g., to clear secretions or to assess for a productive cough), but it is not necessary for palpating fremitus. Tactile fremitus is assessed while the client is speaking (e.g., repeating the phrase "ninety-nine") or breathing, not coughing.
C) Use the bell of the stethoscope:
The bell of the stethoscope is used for auscultating low-pitched sounds, such as heart murmurs or some lung sounds (e.g., certain adventitious sounds like crackles or wheezes). However, it is not used for palpating tactile fremitus, which is a physical exam technique that involves using the hands to feel for vibrations. Fremitus is a tactile (not auscultatory) finding, so the stethoscope, whether bell or diaphragm, is not relevant in this assessment.
D) Instruct the client to breathe deeply:
While it is important for the client to breathe deeply during a lung exam, deep breathing is not directly required for assessing tactile fremitus. Tactile fremitus is typically assessed while the client is speaking. When the client repeats a phrase like "ninety-nine," vibrations are transmitted through the chest wall, and the nurse can assess the intensity of the vibrations. Deep breathing would be more relevant for assessing breath sounds or the general respiratory effort.
Correct Answer is A
Explanation
A) Whisper random numbers and letters, then have the client repeat them:
This is correct. The voice test is a simple way to assess a client's hearing. The nurse should stand about 2 feet away from the client and whisper random numbers or letters. The client should repeat what they hear. This test checks the ability to hear and distinguish sounds, particularly for high-frequency tones. It's an effective screening method for detecting hearing loss.
B) Shield the lips so that the sound is muffled:
This is incorrect. The nurse should not shield their lips during the voice test because it could interfere with the client's ability to hear and potentially read the nurse's lips, which can help with understanding. The client should be allowed to observe lip movements to aid in comprehension of the sounds being spoken.
C) Stand approximately 4 feet away from the client:
This is incorrect. The recommended distance for performing the voice test is typically around 2 feet, not 4 feet. Standing too far away can make it more difficult for the client to hear the whispered numbers or letters and could affect the accuracy of the test. The nurse should stand close enough (about 2 feet) to ensure that the sound is audible to the client but not too close as to distort the test.
D) Have the client place a finger in the ear canal to occlude outside noise:
This is incorrect. While the client should be instructed to avoid distractions or loud environments during the test, placing a finger in the ear canal is not necessary. The test assesses the client's ability to hear sound, and occluding the ear could affect the results. The client should simply be in a quiet environment.
