What is the primary pathophysiology of glaucoma?

Blockage of the tear ducts causing excessive tearing.

Inflammation of the cornea resulting in blurry vision.

Increased intraocular pressure (IOP) leading to optic nerve damage.

Degeneration of the lens leading to cataracts.

Answer and Explanation

The Correct Answer is C

A) Blockage of the tear ducts causing excessive tearing:

Blockage of tear ducts (dacryostenosis) results in excessive tearing (epiphora) due to inadequate drainage of tears into the nasal cavity. It does not directly contribute to glaucoma, which primarily involves increased intraocular pressure (IOP) and optic nerve damage.

B) Inflammation of the cornea resulting in blurry vision:

Corneal inflammation (keratitis) can cause blurry vision, pain, and sensitivity to light, but it is not the primary pathophysiology of glaucoma. Glaucoma primarily involves damage to the optic nerve due to elevated IOP.

C) Increased intraocular pressure (IOP) leading to optic nerve damage:

Glaucoma is characterized by elevated IOP, which puts pressure on the optic nerve and can lead to progressive damage and vision loss if untreated. This is the primary pathophysiological process in most types of glaucoma.

D) Degeneration of the lens leading to cataracts:

Cataracts involve the clouding of the lens of the eye, leading to visual impairment. While cataracts are a common condition in older adults, they are not directly related to the pathophysiology of glaucoma, which primarily involves elevated IOP and optic nerve damage.

Correct Answer is A

Explanation

a) The patient is unable to see in half of the visual field (same visual field) in each eye:

Homonymous hemianopsia is a condition where there is a loss of vision in the same side of the visual field in both eyes. This occurs due to damage to the visual pathways after the optic chiasm, often from a stroke or brain injury, resulting in the loss of either the right or left visual field in both eyes.

b) The patient can see from one eye but not through the other one:

This description fits a condition called monocular blindness, which is typically caused by damage to the optic nerve before it reaches the optic chiasm. Homonymous hemianopsia involves both eyes and specific visual fields, not complete loss of vision in one eye.

c) The patient is unable to see in half of the visual field (opposite visual field) in each eye:

This option describes bitemporal hemianopsia, which results in loss of vision in the outer (temporal) fields of both eyes and is often due to damage at the optic chiasm. Homonymous hemianopsia involves the same side of the visual field in both eyes, not the opposite visual fields.

d) No visual impairment:

Homonymous hemianopsia is characterized by significant visual impairment, specifically the loss of half the visual field in both eyes on the same side. Therefore, it is incorrect to say there is no visual impairment with this condition.

A. Intercostal spaces B. Lymph nodes C. Skin Turgor D. Carotid Pulse

Correct Answer is C

Explanation

A) Intercostal spaces:

Assessing intercostal spaces typically involves palpating or inspecting the area between the ribs to check for abnormalities such as retractions or tenderness, usually conducted with the client sitting or standing.

B) Lymph nodes:

Palpation of lymph nodes, such as in the cervical region, involves using fingertips to gently feel for enlarged or tender nodes. This examination focuses on areas like the neck, underarms, and groin.

C) Skin Turgor:

The image depicts a nurse pinching the skin, likely on the chest or forearm, which is a common method to assess skin turgor. Skin turgor evaluation helps determine hydration status; if the skin remains tented and returns slowly to its original position, it indicates dehydration.

D) Carotid Pulse:

Assessing the carotid pulse involves palpating the carotid artery along the side of the neck to evaluate the strength and rhythm of the pulse. This is typically done using the pads of the fingers, not by pinching the skin.
