- D. all of the above are correct
Correct Answer: D
Rationale: Children with acute lymphocytic leukemia commonly present with a combination of symptoms which can include fatigability, persistent fever of unknown cause, and a tendency to bruise easily. Fatigue is a common complaint in children with leukemia due to anemia caused by decreased production of healthy red blood cells. Persistent fevers can be a sign of infection, anemia, or other complications related to leukemia. Additionally, children with leukemia may have a low platelet count, leading to easy bruising or bleeding tendencies. Therefore, all of the characteristics mentioned in the options are correct for a child with acute lymphocytic leukemia.
A child with thalassemia was given deferoxamine (Desferal); which of the following should alert the nurse to notify the physician?
- A. Decreased hearing
- B. Hypertension
- C. Red urine
- D. Vomiting
Correct Answer: A
Rationale: Deferoxamine is a chelating agent used to treat iron overload in patients such as those with thalassemia. One of the serious side effects of deferoxamine is ototoxicity, which can manifest as decreased hearing or ringing in the ears. Therefore, if a child with thalassemia who is taking deferoxamine experiences a decrease in hearing, the nurse should promptly notify the physician for further evaluation and possible adjustment of the treatment plan to prevent further hearing damage. Hypertension, red urine, and vomiting are possible side effects of deferoxamine, but decreased hearing is the most concerning side effect that requires immediate attention due to the risk of permanent damage.
