Which of the following best describes Hyperopia?
Loss of vision in one eye
Clear vision of nearby objects, but difficulty seeing distant objects
Clear vision of distant objects, but difficulty seeing nearby objects
Blurry vision of both distant and nearby objects
The Correct Answer is C
A) Loss of vision in one eye:
Loss of vision in one eye is not related to hyperopia (farsightedness). This condition could be due to various other causes such as retinal detachment, optic neuropathy, or trauma, but it does not describe the refractive error associated with hyperopia.
B) Clear vision of nearby objects, but difficulty seeing distant objects:
This description pertains to myopia (nearsightedness), where individuals can see nearby objects clearly but struggle with seeing distant objects. Hyperopia is the opposite, involving difficulty with near vision rather than distance vision.
C) Clear vision of distant objects, but difficulty seeing nearby objects:
Hyperopia, or farsightedness, is characterized by clear vision of distant objects while nearby objects appear blurry. This occurs because the eye's light focuses behind the retina rather than directly on it, making close-up tasks like reading challenging.
D) Blurry vision of both distant and nearby objects:
Blurry vision of both distant and nearby objects is not specific to hyperopia and may indicate other eye conditions such as astigmatism or severe refractive errors that affect overall visual acuity, rather than the specific issue of near vision seen in hyperopia.

Correct Answer is A
Explanation
A) Dehydration:
When the skin remains tented and returns to its normal position slowly after being pinched, it indicates decreased skin turgor, which is a clinical sign of dehydration. Dehydration can occur due to fluid loss from sweating during vigorous physical activity like a beach tournament.
B) Hypervolemia:
Hypervolemia refers to excess fluid volume in the body, which would typically manifest with signs such as peripheral edema or jugular vein distention rather than decreased skin turgor.
C) Properly Hydrated:
Properly hydrated individuals would have normal skin turgor, where the skin returns promptly to its normal position after being pinched.
D) Infection:
Skin tenting is not a specific sign of infection. Infection would typically present with localized signs such as redness, warmth, swelling, and possibly systemic signs like fever.
Correct Answer is ["A","C","D"]
Explanation
A) Age 55 years:
Advancing age is a risk factor for skin cancer. As individuals age, the cumulative exposure to UV radiation increases, and the skin's ability to repair damage decreases, leading to a higher risk of skin cancer.
B) Yellow palms of the hands:
Yellow palms are typically associated with conditions like carotenemia or jaundice, not skin cancer. This symptom does not indicate an increased risk of developing skin cancer.
C) Light-colored hair:
Individuals with light-colored hair, especially those with fair skin and light eyes, are at higher risk for skin cancer. They often have less melanin, which provides some protection against UV radiation, increasing their susceptibility to damage from the sun.
D) Actinic keratosis on face:
Actinic keratosis is a precancerous skin lesion caused by long-term sun exposure. It is considered a significant risk factor for developing squamous cell carcinoma, a type of skin cancer. Presence of actinic keratosis should prompt careful monitoring and possibly treatment.
E) Poor skin turgor:
Poor skin turgor typically indicates dehydration or aging but is not directly related to an increased risk of skin cancer. It is more of a general indicator of skin and overall health rather than a specific risk factor for cancer.
