The nurse is caring for a 13-year-old diagnosed with sickle cell anemia. The client asks the nurse what they can do to help prevent sickle cell crisis. What would be an appropriate answer to this client?

Reasoning:

Choice A reason: Monitoring bowel patterns can detect changes in frequency or consistency but is not specific for peptic ulcers. Cushing’s syndrome increases gastric acid production due to cortisol, but altered bowel patterns are more indicative of other gastrointestinal issues, not directly linked to ulcer detection.

Choice B reason: Observing urine output is unrelated to peptic ulcer assessment in Cushing’s syndrome. Urine output reflects renal function or fluid status, not gastrointestinal pathology. Peptic ulcers, caused by cortisol-induced gastric acid hypersecretion, manifest as bleeding or pain, not changes in urine production.

Choice C reason: Observing stool color is critical for detecting peptic ulcers, as cortisol in Cushing’s syndrome increases gastric acid, leading to ulcer formation. Black, tarry stools (melena) indicate gastrointestinal bleeding, a common complication of peptic ulcers, making this the most specific assessment for early detection.

Choice D reason: Monitoring vital signs every 4 hours is routine but not specific for peptic ulcers. While tachycardia or hypotension may indicate severe bleeding, these are late signs. Stool color changes (melena) are earlier and more specific indicators of ulcer-related gastrointestinal bleeding in Cushing’s syndrome.

Reasoning:

Choice A reason: Normal hematocrit is not typical in sickle cell anemia, a hemolytic disorder where red blood cells are destroyed prematurely due to abnormal hemoglobin (HbS). Chronic hemolysis reduces red blood cell mass, lowering hematocrit, making a normal value inconsistent with the disease’s pathophysiology.

Choice B reason: Low hematocrit is characteristic of sickle cell anemia due to chronic hemolysis. Sickled red blood cells have a shorter lifespan, reducing circulating red blood cells and hemoglobin, resulting in a decreased hematocrit. This reflects the anemia’s impact on oxygen-carrying capacity, a hallmark of the condition.

Choice C reason: High hematocrit is not associated with sickle cell anemia. Elevated hematocrit occurs in conditions like polycythemia, where red blood cell mass increases. Sickle cell anemia causes hemolysis, reducing red blood cells and hematocrit, making a high value inconsistent with the disease.

Choice D reason: A normal blood smear is not expected in sickle cell anemia. Blood smears show sickled red blood cells, anisocytosis, and poikilocytosis due to hemoglobin S polymerization. These abnormal findings contrast with a normal smear, which would not reflect the hemolytic and morphological changes of the disease.
