A nurse reviews the chart of a patient who has ulcerative colitis.
Which finding alerts the nurse to urgently contact the provider for additional orders?
White blood cell count of 8,200/mm.
Hemoglobin level of 5.6 g/dL.
Patient’s weight decreased by 3 lbs.
The patient only consumed 20% of breakfast.
The Correct Answer is B
Choice A rationale
A white blood cell count of 8,200/mm is within the normal range, which is typically 4,500 to 11,000 cells/mm. This finding does not indicate a significant infection or inflammatory process, which would be a concern in a patient with ulcerative colitis, and therefore does not require urgent contact with the provider.
Choice B rationale
A hemoglobin level of 5.6 g/dL is critically low. The normal range for hemoglobin is approximately 12.0 to 16.0 g/dL for females and 14.0 to 18.0 g/dL for males. This finding indicates severe anemia, likely from chronic blood loss associated with ulcerative colitis, and could lead to tissue hypoxia and cardiovascular compromise. This requires urgent intervention.
Choice C rationale
A weight decrease of 3 lbs may be concerning but is not as urgent as a critically low hemoglobin level. Weight fluctuations can occur due to dehydration or decreased food intake. While this should be monitored, it does not represent an immediate life-threatening physiological change compared to severe anemia and blood loss.
Choice D rationale
Consuming only 20% of breakfast indicates poor appetite or intolerance, which is common in patients with ulcerative colitis. While this is important to document and monitor for long-term nutritional deficits, it is not an immediate life-threatening finding. A single meal's consumption does not warrant an urgent call to the provider.

Correct Answer is D
Explanation
Choice A rationale
A ham sandwich on white bread and carbonated beverages are low in fiber and can contribute to constipation. White bread is a refined grain, which lacks the dietary fiber found in whole grains. Carbonated drinks can cause gas and bloating. Applesauce contains some fiber, but it is not enough to offset the low-fiber choices, indicating a lack of understanding.
Choice B rationale
Grilled cheese on white bread is low in fiber. While a small banana contains some dietary fiber, it is often insufficient to promote effective elimination, and a grilled cheese sandwich lacks the roughage needed for bowel regularity. The combination of choices suggests the patient has not grasped the importance of a high-fiber diet.
Choice C rationale
Baked tilapia is a good source of protein, and fresh green beans are a good source of fiber. However, a cup of coffee is a diuretic and can lead to dehydration if not balanced with sufficient fluid intake, which can worsen constipation. The patient's selection shows a partial understanding but is not the most optimal choice for promoting elimination.
Choice D rationale
This selection indicates a correct understanding of dietary teaching. Broiled chicken provides protein, while brown rice and steamed broccoli are excellent sources of dietary fiber. Fiber adds bulk to the stool and helps to regulate bowel movements. The glass of apple juice provides additional fluid, which is essential for preventing constipation.
Correct Answer is A
Explanation
Choice A rationale
Individuals of Ashkenazi Jewish descent have a significantly higher incidence of colorectal cancer, primarily due to a specific genetic mutation, the APC I1307K variant, which is more prevalent in this population. This variant confers a moderately increased risk for developing adenomas and, subsequently, colorectal cancer. This genetic predisposition makes this group a high-priority for screening.
Choice B rationale
The incidence of colorectal cancer is generally lower among Asian Americans compared to other racial and ethnic groups in the United States. While lifestyle and dietary changes in immigrant populations may increase their risk over time, their genetic predisposition does not place them at the highest risk.
Choice C rationale
Native Americans generally have a lower incidence of colorectal cancer compared to non-Hispanic whites and African Americans. While risk factors such as obesity and diabetes are prevalent in this population, their overall incidence of colorectal cancer is not the highest among ethnic groups.
Choice D rationale
African Americans have a higher incidence and mortality rate from colorectal cancer compared to non-Hispanic whites. They are at increased risk due to a combination of genetic, socioeconomic, and lifestyle factors. However, the specific genetic risk factor in the Ashkenazi Jewish population results in a notably higher incidence.
