What is the primary clinical manifestation in a child with scabies?

Edema

Maceration

Redness

Pruritus

Answer and Explanation

The Correct Answer is D

A.   Edema (swelling due to fluid accumulation) is not a primary manifestation of scabies. While secondary infections can lead to localized swelling, edema is not characteristic of scabies itself.
B.   Maceration refers to the softening and breaking down of skin resulting from prolonged exposure to moisture. While it can occur if the skin is scratched and becomes wet, it is not a primary clinical manifestation of scabies.
C.   Redness (erythema) can occur due to scratching and irritation, but it is not the defining feature of scabies. While some redness may be present, it is not the primary symptom that indicates scabies infestation.
D.   The primary clinical manifestation of scabies is intense pruritus (itching), which is often worse at night. The itching is a result of an allergic reaction to the mites and their waste products, leading to discomfort and a strong urge to scratch.

Correct Answer is D

Explanation

A. While daycare workers can be at risk for various infections, they are not typically considered at high risk for TB unless they are in close contact with TB-positive individuals. Therefore, this option does not present the highest likelihood of TB.
B. This individual is at a moderate risk for TB, especially if they are caring for patients with known TB or are in an environment where TB may be more prevalent. However, nursing homes are more often associated with other infections rather than being primary sources for TB outbreaks.
C. High school students are generally not at high risk for TB unless they have specific exposure or travel history. Without additional risk factors, this group does not exhibit a high likelihood of TB.
D. This option represents the highest likelihood of TB. Homeless individuals are at increased risk for TB due to factors such as crowded living conditions, poor nutrition, and lack of access to healthcare.

A. "The pressure in the anterior cavity of your eye became elevated, shifting the position of your lens. B. "There's an irregular curvature of your cornea, causing your blurred vision' C. The portion of your eye call the macula, which is responsible for the central vision, is damaged" D. "Your lens became cloudy, causing blurred vision. This cloudiness will increase over time

Correct Answer is C

Explanation

A. This statement describes glaucoma, not macular degeneration. Glaucoma is characterized by increased intraocular pressure that can lead to optic nerve damage and vision loss. It does not specifically pertain to damage of the macula or central vision.
B. This statement refers to conditions like astigmatism, where the cornea has an irregular shape, leading to blurred vision. It is not relevant to macular degeneration, which involves damage to the retina rather than the curvature of the cornea.
C. This statement accurately describes macular degeneration. The macula is the part of the retina responsible for sharp central vision, which is crucial for tasks like reading and recognizing faces. In macular degeneration, this area deteriorates, leading to loss of central vision.
D. This statement describes cataracts, where the lens of the eye becomes cloudy, leading to blurred vision. Cataracts and macular degeneration are distinct conditions, with different causes and impacts on vision.
