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 C
Explanation
Choice a reason:
A penlight is used to provide illumination during an examination, not to move the tongue. It helps the nurse to visualize the mouth floor and other areas by casting light, but it does not have the physical structure to manipulate the tongue.
Choice b reason:
Gloves are worn by healthcare professionals to maintain hygiene and protect both the patient and the nurse from the transmission of infectious agents. They are not used to move the tongue to one side during an examination.
Choice c reason:
A gauze pad is the correct tool to use when the nurse needs to move the tongue to one side during an examination of the mouth floor. The nurse can wrap the gauze pad around the tongue for a better grip, which allows for safe and effective retraction of the tongue without causing discomfort to the patient.
Choice d reason:
A tongue blade, also known as a tongue depressor, is typically used to depress the tongue to examine the back of the throat, not to move the tongue to one side. It is used to hold the tongue down so that the nurse can inspect the oropharynx and other structures.
Correct Answer is B
Explanation
Choice a reason:
Educational Prevention is not a recognized level of prevention in healthcare. While education is a key component in all levels of prevention, it is not a standalone category. Education is typically included in primary prevention as it involves informing the public about health practices to prevent the onset of disease.
Choice b reason:
Tertiary Prevention is the level of prevention that aims to manage and treat an existing disease to prevent further complications or deterioration. In the case of immobile stroke patients, tertiary prevention would involve measures to prevent skin breakdown and other complications associated with immobility and the stroke's long-term effects.
Choice c reason:
Secondary Prevention involves early detection and prompt intervention to prevent the progression of a disease. For stroke patients, secondary prevention might include monitoring for signs of skin breakdown so that early treatment can be initiated. However, the scenario described focuses on managing an existing condition rather than early detection.
Choice d reason:
Primary Prevention aims to prevent the disease or injury before it occurs. This would involve strategies to prevent strokes in the first place, such as controlling high blood pressure or encouraging healthy lifestyle changes. It does not directly relate to the prevention of skin breakdown in patients who have already had a stroke.
