What is considered the most definitive diagnostic test for leukemia?

Chest X-ray

Urinalysis

Complete blood count (CBC)

Bone marrow biopsy and aspiration

Answer and Explanation

The Correct Answer is D

A. Chest X-ray is not a definitive diagnostic test for leukemia. It is more commonly used to evaluate for signs of infection, lung abnormalities, or metastasis in cancer patients, but it does not confirm leukemia.

B. Urinalysis is not the definitive test for leukemia. While it may help assess kidney function or rule out other conditions, it is not used to diagnose leukemia.

C. Complete blood count (CBC) is useful for detecting abnormalities that may suggest leukemia, such as abnormal white blood cell counts, but it alone cannot definitively diagnose leukemia. It is typically part of the initial evaluation.

D. Bone marrow biopsy and aspiration is the definitive diagnostic test for leukemia. This test allows for direct examination of the bone marrow to confirm the presence of leukemia cells, making it the gold standard for diagnosis.

Correct Answer is A

Explanation

A. Increased appetite is not an expected finding in a child with iron deficiency anemia. Children with iron deficiency anemia typically experience a reduced appetite or may develop pica (craving non-food substances) rather than an increased appetite.

B. Pallor is a common sign of iron deficiency anemia, as a lack of iron reduces the number of red blood cells and the amount of hemoglobin, leading to pale skin and mucous membranes.

C. Tachycardia is a compensatory response to anemia, as the heart works harder to deliver oxygen to tissues due to a reduced capacity of the blood to carry oxygen.

D. Brittle spoon-shaped nails (koilonychia) are a classic physical finding in iron deficiency anemia, caused by the reduced oxygen delivery to the nails and skin.

A. "Processed foods are acceptable, as long as they don't contain flour." B. "I need to check food labels for hidden sources of gluten, like barley and rye." C. "I need to avoid foods like bread, pasta, and cereal." D. "My family should use separate serving utensils for gluten-free foods."

Correct Answer is A

Explanation

A. This statement is incorrect because processed foods can contain gluten even if they don't have visible flour. Gluten can be found in many processed foods as an additive or stabilizer, such as in sauces, soups, and processed meats. It's important to always check food labels for gluten ingredients.

B. This is correct. Barley and rye are sources of gluten and must be avoided in a gluten-free diet for those with celiac disease.

C. This is correct. Foods like bread, pasta, and cereal commonly contain gluten and need to be avoided by individuals with celiac disease.

D. This is correct. Using separate serving utensils for gluten-free foods helps prevent cross-contamination, which is critical for managing celiac disease.
