Which of the following are considered normal findings for assessment of the respiratory system? Select all that apply.

Elliptical chest configuration.

Eupnea.

Resonance.

Inspiratory wheezing.

Answer and Explanation

Correct Answer : A,B,C

Choice A rationale

An elliptical chest configuration is considered a normal shape for the thorax. This configuration allows for optimal lung expansion and function. Deviations from this shape, such as a barrel chest, might indicate underlying pulmonary conditions.

Choice B rationale

Eupnea refers to normal, unlabored breathing, which is an expected finding during a respiratory assessment. It indicates that the individual is not experiencing respiratory distress and that their respiratory rate, rhythm, and effort are within normal limits.

Choice C rationale

Resonance is a normal percussion sound heard over healthy lung tissue. It indicates that the underlying lung areas are filled with air, which is a positive sign of healthy lung function.

Choice D rationale

Inspiratory wheezing, a high-pitched whistling sound during breathing, is typically indicative of narrowed or obstructed airways, often associated with conditions such as asthma or chronic obstructive pulmonary disease, and is not considered a normal finding.

Correct Answer is C

Explanation

Choice A rationale

The optic nerve (CN II) is responsible for vision, transmitting visual information from the retina to the brain. Dysfunction of the optic nerve would result in visual disturbances, such as loss of vision or changes in visual acuity, rather than difficulty with tongue movement. This nerve does not control motor functions of the tongue.

Choice B rationale

The abducens nerve (CN VI) controls the lateral rectus muscle of the eye, which is responsible for moving the eye outward, away from the nose. Dysfunction of the abducens nerve would result in issues with eye movement, such as double vision or inability to move the eye laterally, not tongue movement. It does not play a role in tongue motor control.

Choice C rationale

The hypoglossal nerve (CN XII) controls the muscles of the tongue, enabling movements necessary for speech, swallowing, and mastication. Dysfunction of this nerve would result in difficulty protruding the tongue and reduced strength during resistance testing. Symptoms can include atrophy of the tongue muscles, fasciculations, and deviation of the tongue to one side when extended.

Choice D rationale

The vestibulocochlear nerve (CN VIII) is responsible for hearing and balance, transmitting sound and equilibrium information from the inner ear to the brain. Dysfunction of the vestibulocochlear nerve would lead to symptoms such as hearing loss, tinnitus, or balance disorders like vertigo. It does not affect the motor control of the tongue.

A. Patient would be unable to pass the Snellen exam. B. Difficulty seeing from far or at a distance. C. Inability to see objects or letters close in range. D. Patient most likely will pass the Rosenbaum chart.

Correct Answer is C

Explanation

Choice A rationale

Patients with hyperopia (farsightedness) are able to see distant objects clearly but may have difficulty focusing on near objects. They can pass the Snellen exam, which measures distance vision, but may struggle with close-up tasks.

Choice B rationale

Hyperopia involves difficulty seeing close objects, not distant ones. Therefore, patients with hyperopia would not have difficulty seeing from far or at a distance, making this statement incorrect.

Choice C rationale

Hyperopia, or farsightedness, is characterized by the inability to see objects or letters that are close in range. It occurs when the eye's shape causes light to focus behind the retina instead of directly on it, leading to blurred near vision. Corrective lenses can help focus light properly on the retina.

Choice D rationale

The Rosenbaum chart is used to assess near vision acuity, which would highlight issues with hyperopia. However, patients with hyperopia would pass the Snellen exam, which tests distance vision, but might struggle with the Rosenbaum chart. .
