A nurse is teaching a patient who has a history of ulcerative colitis and a new diagnosis of anemia.
Which of the following manifestations of colitis should the nurse identify as a contributing factor to the development of the anemia?
Intestinal parasites.
Chronic blood loss.
Intestinal malabsorption syndrome.
Dietary iron restrictions.
The Correct Answer is B
Choice A rationale
Intestinal parasites can cause anemia through various mechanisms, such as blood loss, nutrient malabsorption, and inflammation. However, this is not a direct manifestation of ulcerative colitis itself but rather a separate potential cause of anemia in any individual. Ulcerative colitis primarily affects the colon and rectum.
Choice B rationale
Chronic blood loss is a significant contributing factor to anemia in patients with ulcerative colitis. The inflammation and ulceration of the colonic mucosa lead to bleeding into the intestinal lumen. Over time, this persistent blood loss can result in iron deficiency anemia, characterized by low hemoglobin and hematocrit levels. Normal hemoglobin ranges are typically 13.5 to 17.5 g/dL for men and 12.0 to 15.5 g/dL for women.
Choice C rationale
Intestinal malabsorption syndrome can lead to anemia by impairing the absorption of essential nutrients like iron, vitamin B12, and folate, which are crucial for red blood cell production. While malabsorption can occur in inflammatory bowel diseases, it is more commonly associated with Crohn's disease, which affects the entire gastrointestinal tract, rather than primarily ulcerative colitis.
Choice D rationale
Dietary iron restrictions would limit the intake of a necessary component for hemoglobin synthesis, potentially leading to or exacerbating anemia. However, this is an external factor and not a manifestation of ulcerative colitis itself. In fact, patients with ulcerative colitis are often encouraged to maintain a diet rich in iron-containing foods to compensate for blood loss.

Correct Answer is A
Explanation
Choice A rationale
Basal cell carcinoma is the most common type of skin cancer and often presents as a raised, flesh-colored or pearly white lesion with rolled borders and sometimes visible blood vessels (telangiectasia). Its slow growth and characteristic appearance align with the description provided.
Choice B rationale
Malignant melanoma is a more aggressive form of skin cancer that typically appears as an asymmetrical mole with irregular borders, uneven color (often shades of black, brown, red, white, or blue), and a diameter greater than 6 mm. It is less likely to present as a raised, flesh-colored lesion with pearly borders.
Choice C rationale
Actinic keratosis is a precancerous skin condition characterized by rough, scaly patches that develop on sun-exposed areas. These lesions are typically flat or slightly raised and can be red, tan, or flesh-colored. The description of pearly white borders does not typically fit actinic keratosis.
Choice D rationale
Squamous cell carcinoma is the second most common type of skin cancer and can appear as a firm, red nodule or a flat lesion with a scaly or crusted surface. While it can vary in appearance, the description of pearly white borders is more characteristic of basal cell carcinoma.
Correct Answer is D
Explanation
Choice A rationale
Stretching exercises primarily improve flexibility and range of motion by elongating muscles and connective tissues. While beneficial for overall fitness, they do not directly address bone density loss, which is the primary concern in osteoporosis. Osteoporosis requires weight-bearing activities to stimulate bone formation.
Choice B rationale
Riding a bicycle is a low-impact aerobic exercise that improves cardiovascular health and muscle strength. However, because it is non-weight-bearing, it does not provide the mechanical stress necessary to promote bone density and is therefore not the most effective exercise for osteoporosis management.
Choice C rationale
High-impact aerobics, such as jumping and running, can increase the risk of fractures in individuals with osteoporosis due to the stress placed on weakened bones. These types of exercises should generally be avoided to prevent injury.
Choice D rationale
Walking briskly is a weight-bearing exercise that applies moderate stress to the bones, stimulating osteoblast activity and promoting bone density. Regular brisk walking can help slow bone loss and reduce the risk of fractures in older adults with osteoporosis.
