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 B
Explanation
Choice A reason:
Reddened intact skin is typically associated with a stage 1 pressure ulcer, where the skin is not yet broken but shows signs of redness. This stage indicates that the skin is under pressure and may be at risk for further breakdown if the pressure is not relieved.
Choice B reason:
A stage 3 pressure ulcer involves full-thickness skin loss that extends into the subcutaneous tissue layer but does not involve underlying muscle or bone. The ulcer presents as a deep crater, and there may be slough or eschar present. It is important to manage these ulcers carefully to prevent further deterioration and complications such as infection.
Choice C reason:
Skin loss involving up to the dermis layer is characteristic of a stage 2 pressure ulcer. In this stage, the epidermis and part of the dermis are lost, creating a shallow open wound or blister. This stage is less severe than stage 3 and requires different management strategies to promote healing and prevent progression.
Choice D reason:
Exposed bone is indicative of a stage 4 pressure ulcer, which is the most severe stage. It involves full-thickness skin loss with extensive destruction, possibly including muscle, tendon, or bone exposure. These ulcers are at high risk for serious infections, including osteomyelitis, and require aggressive medical and surgical intervention to heal.
Correct Answer is C
Explanation
Choice a reason:
Objective data refers to information that is observable and measurable by the healthcare provider, such as vital signs, physical examination findings, and laboratory results. The patient's statements about his feelings are not objective data because they cannot be directly measured or observed by the nurse.
Choice b reason:
Introspective data is not a commonly used term in healthcare. Introspection generally refers to the examination of one's own conscious thoughts and feelings, which in the context of healthcare, can be part of subjective data as it is reported by the patient.
Choice c reason:
Subjective data consists of information that is reported by the patient, including feelings, perceptions, and concerns. It is called 'subjective' because it is based on the patient's personal experience and cannot be independently verified by the nurse. In this case, the patient's report of feeling anxious, nauseated, and hot is considered subjective data.
Choice d reason:
Reflective data is not a standard term in healthcare documentation. Reflection is a process of personal thought and does not pertain to the clinical data gathered during a patient assessment.
