Which information should the nurse give to the parent? 1. The child will have chemotherapy and, after that has been completed, radiation. 2. The child will need to have surgery to remove the tumor. 3. The child will go to surgery for removal of the tumor and the kidney and will then start chemotherapy. 4. The child will need radiation and later surgery to remove the tumor.

3. Combination therapy of surgery and chemotherapy is the primary thera- peutic management. Radiation is done depending on clinical stage and histological pattern.

The nurse is caring for a child who is receiving extensive radiation as part of the treatment for Hodgkin disease. Which intervention should be implemented? 1. Administer pain medication prior to the child's going to radiation therapy. 2. Assess the child for neuropathy since this is a common side effect. 3. Provide adequate rest, as the child may experience excessive malaise and lack of energy. 4. Encourage the child to eat a low-protein diet while on radiation therapy.

3. The most common side effect is extensive malaise, which may be from damage to the thyroid gland, causing hypothyroidism.

The parent of a 4-year-old brings the child to the clinic and tells the nurse the child's abdomen is distended. After a complete examination, a diagnosis of Wilms tumor is sus- pected. Which of the following is most important when doing a physical examination on this child? 1. Avoid palpation of the abdomen. 2. Assess the urine for the presence of blood. 3. Monitor vital signs, especially the blood pressure. 4. Obtain an accurate height and weight.

51. 1. Palpating the abdomen of the child in whom a diagnosis of Wilms tumor is suspected should be avoided, because manipulation of the abdomen may cause seeding of the tumor.

The nurse is caring for a 10-year-old with leukemia who is receiving chemotherapy. The child is on neutropenic precautions. Friends of the child come to the desk and ask for a vase for flowers. Which of the following is the best response? 1. "I will get you a special vase that we use on this unit." 2. "The flowers from your garden are beautiful but should not be placed in the room at this time." 3. "As soon as I can wash a vase, I will put the flowers in it and bring it to the room." 4. "Get rid of the flowers immediately. You could harm the child."

2. A neutropenic client should not have flowers in the room because the flowers may harbor Aspergillus or Pseudomonas aeruginosa. Neutropenic children are susceptible to infection. Precautions need to be taken so the child does not come in contact with any potential sources of infection. Fresh fruits and vegetables can also harbor molds and should be avoided. Telling the friend that the flowers are beautiful but that the child cannot have them is a tactful way not to offend the friend.

To decrease potential for infection. 2. To prevent splenic sequestration. 3. To prevent sickling of red blood cells. 4. To prevent sickle cell crisis.

2. Splenic sequestration is a life- threatening situation in children with sickle cell anemia. Once a child is considered to be at high risk of splenic sequestration or has had this in the past, the spleen will be removed.

A child has completed treatment for leukemia and comes to the clinic with the parents for a checkup. The parents express to the nurse that they are glad their child has been cured of cancer and is safe from getting cancer later in life. Which of the following should the nurse consider in responding? 1. Childhood cancer usually instills immunity to all other cancers. 2. Children surviving one cancer are at higher risk for a second cancer. 3. The child may have a remission of the leukemia but is immune to all other cancers. 4. As long as the child continues to take steroids, there will be no other cancers.

2. The most devastating late effect of leukemia treatment is development of secondary malignancy.

When caring for a child with lymphoma, the nurse needs to be aware of which of the following? 1. The same staging system is used for lymphoma and Hodgkin disease. 2. The aggressive chemotherapy with central nervous system prophylaxis will give the child a good prognosis. 3. All children with lymphoma need a bone marrow transplant for a good prognosis. 4. Despite high-dose chemotherapy, the prognosis is very poor for most children with a diagnosis of lymphoma.

2. The use of aggressive combination chemotherapy has a major impact on the survival rates for children with a diagnosis of lymphoma. Because there is usually bone marrow involvement, there is a need for central nervous system prophylaxis.

A nurse is caring for a 5-year-old with sickle cell vaso-occlusive crisis. Which of the following orders should the nurse question? Select all that apply. 1. Position the child for comfort. 2. Apply hot packs to painful areas. 3. Give Demerol 25 mg intravenously every 4 hours as needed for pain. 4. Restrict oral fluids. 5. Apply oxygen per nasal cannula to keep oxygen saturations above 94%.

3, 4. 1. Medical treatment of sickle cell crises is directed toward preventing hypoxia. Tissue hypoxia is very painful, so placing the child in a position of comfort is important. 2. Hot packs help relieve pain because they cause vasodilation, which allows increased blood flow and decreased hypoxia. 3. Tissue hypoxia is very painful. Narcotics such as morphine are usually given for pain when the child is in a crisis. Demerol should be avoided because of the risk of Demerol-induced seizures. 4. The child should receive hydration because when the child is in crisis, the abnormal S-shaped red blood cells clump, causing tissue hypoxia and pain. 5. Providing oxygen when the oxygen satura- tion decreases helps treat the hypoxia.

The physical examination is normal, but his hematocrit level is 20%. Which of the following questions should assist the nurse in making a diagnosis? Select all that apply. 1. "How many bowel movements a day does your child have?" 2. "How much did your baby weigh at birth?" 3. "What does your child eat every day?" 4. "Has the child been given any new medications?" 5. "How much milk does your child drink per day?"

3, 5. 1. Because the child has a low hematocrit level, the child most likely has anemia. Iron-deficiency anemia is the most common nutritional anemia. The number of bowel movements the child has is important information but not necessary to make the diagnosis of iron-deficiency anemia. 2. Knowing birth weight can help determine if the child is following his or her own curve on the growth chart. 3. A diet history is necessary to determine the nutritional status of the child and whether the child is getting sufficient sources of iron. 4. Knowing if the child is taking any new med- ication is good but is not necessary to make the diagnosis of iron-deficiency anemia. 5. By asking how much milk the child con- sumes, the nurse can determine whether the child is filling up on milk and then not wanting to take food.

Which of the following should be done to protect the central nervous system from the invasion of malignant cells in a child newly diagnosed with leukemia? 1. Cranial and spinal radiation. 2. Intravenous steroid therapy. 3. Intrathecal chemotherapy. 4. High-dose intravenous chemotherapy.

Which of the following should the nurse expect to administer to a child with ITP and a platelet count of 5000/mm3? 1. Platelets. 2. Intravenous immunoglobulin. 3. Packed red blood cells. 4. White blood cells.

2. Intravenous immunoglobulin is given because the cause of platelet destruc- tion is believed to be an autoimmune response to disease-related antigens. Treatment is usually supportive. Activity is restricted at the onset because of the low platelet count and risk for injury that could cause bleeding.
