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 B

Explanation

A. Just after the child falls asleep is not the correct timing. The tape test should be performed in the morning before the child toilets or bathes, not immediately after they fall asleep.

B. Before the child toilets or bathes is correct. The tape test is most effective when the tape is applied to the perianal area before the child uses the toilet or bathes in the morning, as pinworm eggs are typically laid at night and can be collected before washing.

C. After the child awakes is incorrect. The tape should be applied before the child uses the toilet or bathes in the morning to ensure the best chance of collecting pinworm eggs.

D. Before the child falls asleep is incorrect. The tape should be applied in the morning, not at night, to collect pinworm eggs effectively.

A. An elevated red blood cell count B. A decreased white cell count C. An elevated white blood cell count D. A normal glucose

Correct Answer is C

Explanation

A. An elevated red blood cell count is not a typical finding in bacterial meningitis. An increase in red blood cells in cerebrospinal fluid (CSF) is more indicative of a traumatic lumbar puncture or hemorrhage.

B. A decreased white cell count would not be expected in bacterial meningitis. Bacterial infections typically lead to an increase in white blood cell count as part of the immune response to fight the infection.

C. An elevated white blood cell count is a hallmark of bacterial meningitis. This finding indicates an immune response in the CSF to the presence of bacteria. The cells are primarily neutrophils in bacterial infections.

D. A normal glucose level is not expected in bacterial meningitis. Glucose is typically decreased due to the consumption of glucose by bacteria and white blood cells in the CSF.
