Which type of skin cancer can be recognized in the lesion’s character based on the ABCD rule?
Squamous cell carcinoma
Basal cell carcinoma
Melanoma
Sarcoma
The Correct Answer is C
The ABCD rule is a mnemonic used to identify the characteristics of melanoma, which is a type of skin cancer. The leters stand for:
A -Asymmetry: One half of the mole or lesion does not match the other half.
B - Border irregularity: The edges are ragged, notched, or blurred.
C - Color: The color is not uniform and may include different shades of brown or black, or sometimes patches of pink, red, white, or blue.
D - Diameter: The size of the mole or lesion is greater than 6 mm (about the size of a pencil eraser), although melanomas can sometimes be smaller.
This rule is not as useful in detecting other types of skin cancer, such as squamous cell carcinoma, basal cell carcinoma, or sarcoma, as they tend to have different characteristics. However, any new or changing mole or lesion on the skin should be examined by a dermatologist to determine if it is cancerous.

Explanation
Digestion begins in the oral cavity, also known as the mouth, where food is ingested and broken down into smaller pieces through mechanical digestion by the teeth and chemical digestion by enzymes in saliva, such as amylase. Once the food is sufficiently broken down, it forms a bolus and is then swallowed, passing through the esophagus and into the stomach. In the stomach, the food is further broken down by stomach acid and enzymes before passing into the small intestine for the absorption of nutrients.

Correct Answer is C
Explanation
The popliteal artery is located behind the knee and is one of the major arteries that supplies blood to the leg and foot. Palpating the pulse in this artery can be done by pressing firmly on the area behind the knee, just below the crease. It is important to note that palpating the pulse in this area can be more difficult than other pulse points, as the artery is deep and surrounded by other structures such as muscle and bone.
