Complications of anemia are due to:
An inability of the body to produce clotting factors.
An increase in the number of mature red blood cells.
Reduced oxygen transport in the blood.
Increased white blood cell production.
The Correct Answer is C
A. An inability of the body to produce clotting factors is incorrect because anemia does not directly affect clotting factor production. Clotting factors are primarily produced by the liver, and disorders affecting clotting are separate from red blood cell deficiencies.
B. An increase in the number of mature red blood cells is incorrect because anemia is characterized by a decrease in red blood cells or hemoglobin, not an increase. An elevated red blood cell count is seen in conditions like polycythemia, not anemia.
C. Reduced oxygen transport in the blood is correct because anemia results in a decreased number of red blood cells or insufficient hemoglobin, which reduces the blood’s capacity to carry oxygen to tissues and organs. This leads to symptoms such as fatigue, weakness, pallor, shortness of breath, dizziness, and tachycardia. Severe anemia can cause hypoxia, organ dysfunction, and, in critical cases, heart failure due to the heart compensating for low oxygen delivery.
D. Increased white blood cell production is incorrect because anemia does not cause an increase in white blood cells. WBC production is related to immune function and infection, not red blood cell deficiency.

Correct Answer is ["A","B","C","E"]
Explanation
A. Development of an odd-shaped lesion or new mole is correct because new or unusually shaped lesions can indicate abnormal cell growth. The appearance of a mole that differs from existing moles (the “ugly duckling” sign) is a warning sign of potential skin cancer.
B. A lesion that does not heal is correct because non-healing sores, ulcers, or lesions can indicate skin malignancy, particularly squamous cell carcinoma or melanoma. Persistent lesions should be evaluated promptly.
C. A change in the shape, color, or size of a mole is correct because changes in a mole are part of the ABCDE warning signs of melanoma. Rapid changes or irregular features are concerning for malignancy.
D. Freckles that darken slightly with sun exposure is incorrect because normal freckles darken with UV exposure but are not considered warning signs. This is a physiologic response to sunlight, not indicative of cancer.
E. Skin lesions that repeatedly bleed is correct because recurrent bleeding, especially from a mole, lesion, or sore, is a classic warning sign of malignant transformation. Bleeding often occurs due to fragile, abnormal blood vessels within the lesion.
Correct Answer is B
Explanation
A. 31.5 %: Underestimates TBSA; likely missed one major area such as the anterior torso or leg portion.
B. Using the Rule of Nines for adults: Entire front of torso (anterior trunk) = 18%, entire right arm = 9%; front of right leg (anterior half of one leg) = 9%; face and front of neck (anterior head/neck) = 4.5%. Total TBSA = 18 + 9 + 9 + 4.5 = 40.5%
C. 49.5 %: Overestimates TBSA; may have incorrectly counted the entire leg (18%) instead of just the front (9%).
D. 36 %: Slight underestimation; possibly omitted the face/neck portion (4.5%).
