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:
Pigeon Chest, or pectus carinatum, is a condition where the breastbone is pushed outward, and the chest appears to protrude. It is not typically associated with a barrel-shaped chest, which is characterized by a rounded and bulging appearance.
Choice b reason:
Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus. While it can cause chest expansion, it does not lead to a barrel-shaped chest. The barrel-shaped chest is more indicative of a chronic condition rather than an acute infection like pneumonia.
Choice c reason:
Funnel Chest, or pectus excavatum, is a condition where the breastbone is sunken into the chest. Unlike a barrel-shaped chest, funnel chest gives the chest a depressed appearance.
Choice d reason:
COPD, or Chronic Obstructive Pulmonary Disease, is commonly associated with a barrel-shaped chest. This shape results from the chronic hyperinflation of the lungs due to obstructive lung disease, which causes the rib cage to remain expanded.
Correct Answer is A
Explanation
Choice a reason:
Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones. This can lead to a variety of symptoms, including hoarseness, fatigue, and weight gain. The hoarseness can be due to the effect of hormone deficiency on the vocal cords, while fatigue and weight gain are common due to the slowed metabolism associated with hypothyroidism.
Choice b reason:
Gingivitis is inflammation of the gums and does not typically cause hoarseness, fatigue, or weight gain. It is more commonly associated with symptoms like red, swollen gums and bleeding during brushing or flossing.
Choice c reason:
Aphthous ulcers, also known as canker sores, are small, shallow lesions that develop on the soft tissues in the mouth or at the base of the gums. While they can be painful and cause difficulty with eating and speaking, they do not cause systemic symptoms such as hoarseness, fatigue, or weight gain.
Choice d reason:
Dysphagia, or difficulty swallowing, can lead to hoarseness if there is an associated throat disorder. However, it is not typically associated with systemic symptoms like fatigue and weight gain unless it is part of a broader condition that affects the body's metabolism or energy levels.
