A nurse is providing care to an infant newly diagnosed with sickle cell anemia. The infant's parents ask the nurse to describe what sickled red blood cells are and how they affect blood flow. Which of the following statements should the nurse include in the discussion? (Select All that Apply.)

"Sickled red blood cells are flexible, making it easier for these cells to travel through small vessels."

"Sickled red blood cells are c-shaped and tend to stick together more easily."

"Sickled red blood cells have a long-life span. Therefore, they circulate in the blood longer than healthy cells."

"Sickled red blood cells are rigid, making it difficult for the cells to travel through smaller vessels."

"Sickled red blood cells have a short life span which decreases the number of red blood cells circulating in the blood."

Answer and Explanation

Correct Answer : B,D,E

A. Sickled red blood cells are flexible, making it easier for these cells to travel through small vessels is incorrect. Sickled red blood cells are rigid and inflexible, which makes it difficult for them to pass through small blood vessels, contributing to blockages and reduced oxygen delivery.

B. Sickled red blood cells are c-shaped and tend to stick together more easily is correct. Sickled red blood cells have an abnormal, crescent or "C" shape, and they stick together, which can cause clumping and block blood flow in small vessels, leading to pain and organ damage.

C. Sickled red blood cells have a long-life span. Therefore, they circulate in the blood longer than healthy cells is incorrect. Sickled red blood cells have a shortened life span (about 10-20 days) compared to normal red blood cells, which typically last 120 days, leading to a higher rate of cell destruction and anemia.

D. Sickled red blood cells are rigid, making it difficult for the cells to travel through smaller vessels is correct. The rigidity of sickled cells prevents them from easily moving through small blood vessels, causing occlusions, pain, and organ damage.

E. Sickled red blood cells have a short life span which decreases the number of red blood cells circulating in the blood is correct. Due to their short life span, sickled cells are destroyed more quickly, leading to anemia and reduced oxygen-carrying capacity in the blood.

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.
