The nurse read the patient's health history and noted cranial nerve III oculomotor paralysis. Which of the following would the nurse expect?
The eye cannot look to the outside.
Myopia.
Ptosis will be evident and no pupillary constriction.
Normal eye movement.
The Correct Answer is C
Choice a reason:
The inability of the eye to look outward, known as lateral rectus palsy, is associated with cranial nerve VI, the abducens nerve, not the oculomotor nerve. The oculomotor nerve does not control the lateral rectus muscle which governs this movement.
Choice b reason:
Myopia, or nearsightedness, is a refractive error of the eye where distant objects appear blurry while close objects can be seen clearly. It is not related to oculomotor nerve paralysis, which affects eye movements and pupil response, not the shape of the eyeball or the refractive properties of the lens.
Choice c reason:
Ptosis, or drooping of the upper eyelid, and an absence of pupillary constriction are classic signs of oculomotor nerve paralysis. The oculomotor nerve controls most of the eye's movements, including lifting the eyelid via the levator palpebrae superioris muscle and constricting the pupil through the circular muscles of the iris.
Choice d reason:
Normal eye movement would not be expected in a patient with oculomotor nerve paralysis. This nerve controls the majority of the eye's movements, so paralysis would lead to abnormal eye movement, such as the inability to move the eye upward, downward, or inward.

Correct Answer is D
Explanation
Choice a reason:
Bronchovesicular sounds are normal breath sounds heard over the main bronchus area and over the upper right posterior lung field. They have a medium pitch and intensity and are heard on both inspiration and expiration. Bronchovesicular sounds do not involve the change of vowel sounds during auscultation.
Choice b reason:
Bronchophony is the term used when the voice sounds are more clear and louder over the chest wall, usually indicating lung consolidation. However, it does not specifically refer to the change of vowel sounds from "ee" to "ay."
Choice c reason:
Normal voice resonance is when voice sounds heard through auscultation are muffled and indistinct. It does not involve a clear change in vowel sounds, which is what occurs with egophony.
Choice d reason:
Egophony is characterized by the change of the "ee" vowel sound to a nasal "ay" or "a" sound when auscultating the lungs. This phenomenon typically suggests lung consolidation, as might be seen with pneumonia.
Correct Answer is D
Explanation
The correct answer is d) Stage II.
Choice a reason:
Stage IV pressure ulcers are the most severe, with full-thickness skin loss and exposed bone, tendon, or muscle. Signs of stage IV include large-scale tissue loss, possibly including slough or eschar, and may include undermining and tunneling. The scenario described does not indicate such an advanced stage, as there is no mention of exposed deeper tissues or structures.
Choice b reason:
Stage III pressure ulcers involve full-thickness skin loss, potentially affecting subcutaneous tissue but not extending to underlying muscle or bone. The wound may have a crater-like appearance. The described condition does not match stage III, as there is no indication of the ulcer extending into subcutaneous tissue.
Choice c reason:
Stage I pressure ulcers present with intact skin and non-blanchable redness of a localized area usually over a bony prominence. The skin may be painful, firm, soft, warmer, or cooler compared to adjacent tissue. In the given scenario, the skin is not intact, ruling out stage I.
Choice d reason:
Stage II pressure ulcers are characterized by partial-thickness loss of dermis presenting as a shallow open ulcer with a red-pink wound bed, without slough. They may also present as intact or ruptured blisters. The description of the skin condition with erythema, serosanguineous drainage, and a blister-like appearance aligns with a stage II pressure ulcer.
