A client reports experiencing blurry central vision that has recently worsened. Which pathological process supports the client's subjective report?

Blockage of retinal capillaries causing ischemic damage of the central macular area.

Opaque spoke-like lines developing in the periphery of the lens to the center.

Tears in the retina that detach from the lining of the posterior eyeball.

An increase in intraocular pressure with loss of peripheral vision.

Answer and Explanation

The Correct Answer is A

A) Blockage of retinal capillaries causing ischemic damage of the central macular area:

Correct. Blurry central vision that worsens over time can be indicative of macular ischemia, often caused by blockage of retinal capillaries leading to ischemic damage of the central macular area. This condition can occur in diseases such as diabetic retinopathy or retinal vein occlusion.

B) Opaque spoke-like lines developing in the periphery of the lens to the center:

This description is more characteristic of cataracts, which cause visual disturbances such as glare or halos around lights rather than blurry central vision.

C) Tears in the retina that detach from the lining of the posterior eyeball:

Retinal tears and subsequent detachment can cause visual disturbances, but they typically present as sudden onset of floaters, flashes of light, and a curtain-like shadow over the visual field rather than blurry central vision.

D) An increase in intraocular pressure with loss of peripheral vision:

This description is indicative of glaucoma, which can lead to loss of peripheral vision (visual field defects) rather than blurry central vision. Glaucoma-related visual field loss usually begins peripherally and progresses inward, affecting central vision in later stages.

Correct Answer is C

Explanation

Benign prostatic hyperplasia (BPH) is a condition characterized by non-cancerous growth of the prostate gland, leading to its enlargement. This enlargement can contribute to urinary retention by obstructing the flow of urine through the urethra. Here's the breakdown of the explanation:

A) Abnormal growth results in loss of bladder muscle tone:

While BPH can lead to urinary symptoms such as urinary frequency, urgency, and nocturia, it does not directly cause loss of bladder muscle tone. Instead, the enlarged prostate gland obstructs the bladder outlet, making it difficult for urine to pass through the urethra.

B) Inflammation causes spasms of the gland:

Inflammation of the prostate gland, known as prostatitis, can cause symptoms such as pelvic pain, dysuria, and urinary frequency, but it is not typically associated with BPH. BPH is characterized by benign growth of the prostate tissue rather than inflammation and spasms.

C) The enlarged gland compresses the urethra:

Correct. The primary mechanism by which BPH causes urinary retention is by compressing the urethra, which obstructs the flow of urine from the bladder. As the prostate gland enlarges, it can constrict the urethra, leading to symptoms such as hesitancy, weak urinary stream, incomplete emptying, and urinary retention.

D) Nerve compression decreases the sensation that the bladder is full:

While compression of nerves in the pelvic region can contribute to urinary symptoms, such as decreased sensation of bladder fullness, it is not the primary mechanism by which BPH causes urinary retention. The compression of the urethra by the enlarged prostate gland is the main factor leading to urinary obstruction and retention.

A. Small, skin-colored, pedunculated papules in areas of skin folds and on other areas as skin tags. B. Hyperpigmented areas that vary in form and color and are slightly elevated from the skin. C. Hyperactive sebaceous areas forming comedones, papules, pustules on the face, neck, and upper back. D. Sharply demarcated silvery scaling plaques with underlying redness on the elbows and knees.

Correct Answer is C

Explanation

Acne vulgaris is a common skin condition characterized by various types of lesions, including comedones, papules, and pustules, primarily affecting areas with a high density of sebaceous glands, such as the face, neck, chest, and upper back. Here's why option C is the correct choice:

A) Small, skin-colored, pedunculated papules in areas of skin folds and on other areas as skin tags:

This description is more characteristic of acrochordons or skin tags, which are benign skin growths commonly found in areas of friction or skin folds. Skin tags are not typically associated with acne vulgaris.

B) Hyperpigmented areas that vary in form and color and are slightly elevated from the skin:

This description suggests post-inflammatory hyperpigmentation, which can occur after resolution of inflammatory lesions in acne vulgaris. However, it does not capture the primary pathological findings observed in active acne lesions.

C) Hyperactive sebaceous areas forming comedones, papules, pustules on the face, neck, and upper back:

Correct. Acne vulgaris is characterized by the formation of various lesions, including comedones (open and closed), papules, and pustules, resulting from the obstruction of hair follicles and overactivity of sebaceous glands. These lesions typically appear on areas with a high density of sebaceous glands, such as the face, neck, chest, and upper back.

D) Sharply demarcated silvery scaling plaques with underlying redness on the elbows and knees:

This description is more indicative of psoriasis, a chronic autoimmune skin condition characterized by sharply demarcated, raised, silvery scaling plaques commonly affecting extensor surfaces such as the elbows and knees. Psoriasis lesions are distinct from those seen in acne vulgaris.
